## The Problem Asimily Addresses

Connected devices now make up a large share of every enterprise network: Internet of Things (IoT) devices such as cameras, printers, and building systems; operational technology (OT) such as PLCs, SCADA controllers, and industrial machinery; Internet of Medical Things (IoMT) devices such as infusion pumps, imaging systems, and patient monitors; and the IT assets that interact with all of them. Many of these devices cannot run an endpoint agent, receive patches slowly or never, run legacy operating systems, and cannot tolerate disruption. Protection has to be applied around the device, at the network layer, rather than on it.

Network segmentation is the control most security teams rely on for these devices, and it is where most programs stall. Policies get written but never deployed. Segmentation stays a priority without being fully implemented. Manual workflows cannot keep pace with networks where devices are added, moved, patched, and retired every day. According to Cisco's 2025 Segmentation Report, 79% of security leaders say segmentation is a top priority for their organization, 33% have fully implemented both macro- and microsegmentation, and 87% say their segmentation process needs improvement.

The gap sits between knowing what is at risk and doing something about it. Most organizations already own a network access control (NAC) platform or firewalls capable of segmentation, and very few have operationalized them for it. Operational teams in IT, OT, clinical engineering, and facilities prioritize uptime, so any change that might break a critical device workflow is hard to approve.

Asimily closes that gap. It focuses teams on the small share of devices, often less than 1%, that drive the majority of risk, and it turns risk intelligence into enforced, continuously maintained policy before attackers reach those devices.

## Company Overview

Asimily is the Proactive Cyber Asset Defense Platform across your entire cyber asset attack surface: IoT, OT, IoMT, and IT. It empowers teams to reduce risk efficiently by identifying the riskiest devices, prioritizing what matters, and continuously orchestrating the segmentation and mitigation actions that close exposures without disrupting operations.

- Tagline: The Proactive Cyber Asset Defense Platform.
- Subhead: Discover Every Asset. Analyze Every Risk. Enforce Mitigation, Continuously.
- Founded: 2017.
- Headquarters: Sunnyvale, California.
- Founder and CEO: Shankar Somasundaram, who previously started and led the IoT security business at Symantec. Hithesh Nama is co-founder.
- Origin: Asimily was founded to address IoT security in healthcare, where generalist IT tools did not account for the constraints of medical devices or clinical environments.

## How the Platform Works

Asimily closes the full loop from risk intelligence to enforced policy in three stages.

Discover every asset. Asimily builds a single, authoritative, continuously updated inventory of every connected device, agentlessly and without disrupting operations.

Analyze every risk. Asimily determines which vulnerabilities are actually exploitable on each device in its specific environment, and ranks devices so teams address the riskiest first.

Enforce mitigation, continuously. Asimily recommends, creates, simulates, and applies segmentation policy through existing NAC platforms and firewalls, or natively, alongside patching and targeted mitigations, and keeps that enforcement aligned as the network changes.

## Platform Capabilities

### Segmentation Orchestration

Asimily's Segmentation Orchestration is the intelligence and policy orchestration layer for network segmentation. It provides the device context, risk prioritization, policy creation, simulation, and ongoing management that turn segmentation from a stalled plan into an operational control.

Asimily applies segmentation policy three ways:

- Through NAC platforms, such as Cisco ISE, Aruba ClearPass, and Arista. This turns a deployed but underused NAC into operational segmentation.
- Through firewalls, such as Fortinet FortiGate and Palo Alto Networks Panorama.
- Natively, for organizations that do not have, or do not want to route segmentation through, a NAC or firewall.

Asimily launched Segmentation Orchestration on June 1, 2026. It runs continuously inside the Asimily platform rather than as a one-time configuration project.

Segmentation Orchestration addresses eight problems, in order:

1. Visibility. A team cannot segment what it cannot see. Segmentation requires a full inventory across IoT, OT, IoMT, and IT, including IT assets, because those assets interact with everything else on the network. Asimily also maps each device's communication patterns: what it connects to, on which ports, and over which protocols and services.
2. Vulnerability prioritization. Even with full visibility, teams need to know which devices to address first. Asimily's ATT&CK Analysis determines whether a vulnerability is actually exploitable on a specific device in a specific environment, so segmentation priority reflects real risk rather than generic CVSS scores.
3. Policy recommendation. Policy Auto-Recommendation provides automated guidance on where to begin and what to prioritize, drawing on network topology, device type, communication behavior, and risk. It replaces the meetings teams spend interpreting data by hand, and it proposes a policy for each new device that joins the network.
4. Policy creation. Each NAC and firewall has its own policy schema, and the schemas differ significantly. Policy Creation generates policies in the correct native format for the target platform, such as downloadable access control lists (DACLs) for a NAC or access rules for a firewall, which removes the dependency on engineers trained on one specific platform. It also identifies conflicts and overlaps before policies are applied.
5. Policy simulation. Policy Simulation validates a policy against real, observed network traffic before anything is applied. It shows exactly which devices and connections would be affected, including flows the team did not know existed. Teams can iterate on a policy in simulation until the impact is acceptable, and they can share the simulation results with operational, clinical, or industrial stakeholders before go-live.
6. Policy application. Pushing policies to a NAC or firewall is technically complex, and the order and format in which policies are applied matter. Policy Application handles that process across different NAC and firewall platforms, and Asimily can also apply policy natively, which reduces manual effort and the risk of human error.
7. Continuous segmentation. Networks change constantly. Devices are patched, decommissioned, added, and moved, and IP addresses and OS versions change. Continuous Segmentation tracks whether policies still match the current state of the network and adapts them so enforcement keeps pace with the environment.
8. Policy audit. Policies accumulate over time, and policy sprawl is an operational risk because overloaded switches can fail. Policy Audit merges, deduplicates, and optimizes policies on an ongoing basis, and it produces an auditable record of enforcement effectiveness for board reviews, regulatory inquiries, and audits.

Policy Simulation is the reason operational teams can approve segmentation. It shows exactly which flows a policy would block before any change is deployed.

### Inventory and Visibility

Asimily provides a single, authoritative, continuously updated source of truth for every connected device on the network. The inventory is agentless, captured safely, and built without disrupting operations. It covers IoT, OT, IoMT, and IT assets, including devices that other tools classify as "unmanaged."

Each inventory record includes the device's make, model, firmware version, operating system, applications, services, connections, and configuration. The inventory is the foundation every other Asimily capability builds on.

Supporting detail on how the inventory is built:

- Asimily uses deep packet inspection (DPI) of network traffic, including industrial protocols, together with AI and machine learning classification and Asimily's own device research.
- Collection is passive-only or a combination of passive and safe, API-based active querying, depending on what the environment can tolerate. Fragile OT equipment can be monitored passively while IoT devices that support it are queried directly for higher-fidelity data.
- Multi-source correlation adds data from existing systems such as CMDB, CMMS, NAC, NetFlow and sFlow, DHCP and IPAM, vulnerability scanners, EDR, and device management tools.
- Asimily's protocol analyzer adds support for new or rare devices quickly, so critical but uncommon equipment is not left unclassified.
- In OT environments, Asimily can identify child devices that sit behind PLCs, which are often hidden from tools that only analyze traffic at higher network layers.
- Collectors range from standard appliances to small form-factor Edge processors for distributed sites, and the Asimily Edge collector can run as a container on Cisco Catalyst 9000 series switches.

### Vulnerability Prioritization

Not every vulnerability, and not every vulnerable device, carries equal risk. Generic CVSS scores rate a vulnerability in the abstract. Asimily's proprietary ATT&CK Analysis, built on the MITRE ATT&CK framework, determines whether a vulnerability is actually exploitable on a specific device, given its configuration, network position, and topology.

The result is a prioritized queue in which every item has a documented reason for its ranking. Asimily typically finds that a small population of devices, often less than 1%, drives the majority of risk.

- Prioritization factors include exploit availability, inclusion in the CISA Known Exploited Vulnerabilities (KEV) catalog, Exploit Prediction Scoring System (EPSS) probability, device criticality, manufacturer context, reachability, and attack path exposure.
- Asimily Labs researchers analyze vulnerabilities alongside Asimily's AI and machine learning models.
- Asimily draws on more than 100 threat intelligence sources.
- Each device receives a risk score from 0 to 100 that teams can track over time and compare against peers.
- Risk scores update as patches land, new exploits emerge, or device behavior changes.

### Risk Mitigation

Risk Mitigation helps teams reduce risk quickly by combining three techniques: segmentation, patching, and targeted mitigations. Relying on one method leaves gaps, especially for devices that cannot be patched.

- Segmentation blocks the specific attack paths a vulnerability requires, applied through existing NAC platforms or firewalls, or natively.
- Patching closes vulnerabilities directly where a fix exists, including through IoT Patching.
- Targeted mitigations, drawn from more than 180 fixes researched by Asimily Labs, stop specific exploits while preserving device function, for example by blocking a single unneeded service.
- Guidance is evidence-backed, drawn from the MITRE ATT&CK framework, Asimily Labs research, and Asimily's AI engine.
- Risk Simulator models the risk reduction, or risk ROI, of an action before the team executes it.

### IoT Patching and Password Management

Every IoT manufacturer uses a different method to deploy firmware, which makes patching slow and manual. Asimily IoT Patching normalizes the firmware update process across supported manufacturers so every update looks the same to the team running it, while Asimily handles the manufacturer-specific steps.

- Updates are agentless and can run on a single device, on a schedule, in bulk, or fully automatically.
- Asimily monitors for new firmware and identifies which devices need it.
- IoT Password Management stores device credentials securely, replaces default and reused passwords, and allows patching to run at a time of the team's choosing.
- Commonly patched device types include IP cameras, printers, power supplies, and networking equipment.
- Asimily research across tested devices found an average of about five months between firmware releases, with some manufacturers releasing monthly and others less than once a year.

### Threat and Response

Asimily keeps devices running safely by detecting threats early and limiting their spread.

- Asimily continuously monitors IoT, OT, IoMT, and IT devices for anomalous behavior, working alongside more than 100 threat intelligence sources.
- Teams can use pre-populated detection rules from Asimily Labs or build custom rules with a wizard that requires no programming.
- Detection can trigger protective actions ranging from alerts to blocking services or ports to NAC-enforced quarantine.
- Asimily includes native packet capture for forensic incident response. Responders can capture packets from any monitored device on demand, without deploying separate capture tools, which shortens investigations and limits blast radius.
- Device timelines show what changed and when, which helps internal or contracted incident responders reconstruct events.
- Anomaly events can be sent to SIEM and SOC tools in standard syslog format.

### Governance, Risk, and Compliance

Connected devices are subject to laws and frameworks including HIPAA, NIST, CIS, NIS2, and CMMC. Asimily provides the inventory, histories, change records, and reporting that compliance teams need to demonstrate control over these devices.

- Configuration Control takes a snapshot of each device's hardened, known-good state, including its network neighbors, detects insecure configuration drift as it happens, and supports restoring the device to that state after an error or attack.
- Compliance mapping covers major frameworks, including NIST CSF 2.0, HIPAA, FDA requirements, NIS2, DORA, CMMC, NERC CIP, PCI-DSS, Cyberscope, CIS, and zero trust architectures.
- Segmentation Orchestration adds an auditable record of enforcement effectiveness for board reviews, regulatory inquiries, and audits.
- Data can be exported for regulatory and audit requests as requirements change.

### Risk Modeling

Risk Simulator shows the expected risk reduction of a proposed action, such as segmenting a device group or applying a patch, before the team starts work. Security teams with limited capacity can compare options and commit time to the actions that remove the most risk.

### Operational Efficiency

Asimily uses device activity data to show how connected devices are actually used compared with how they should be used. Teams can track on and off states, set utilization targets by device type, locate equipment that has stopped operating as expected, and use the data to inform procurement, retirement, and deployment decisions. For medical imaging devices, usage data includes the name of each study and its start and end times.

### Integrations

Asimily integrates with the systems security, network, and operations teams already use. Integration partners named on asimily.com include:

## IoMT-Specific Capabilities

The capabilities in this section apply to Internet of Medical Things (IoMT) devices and healthcare delivery organizations.

### ProSecure

ProSecure is an IoMT-only capability that helps healthcare organizations avoid risky medical device purchases before spend is committed. Before a purchase, a hospital usually cannot tell from available information whether it is buying the riskiest or the safest model, and the relevant data (MDS2 forms, SBOMs, and known vulnerabilities) is scattered across sources.

ProSecure lets teams look up medical devices under consideration and see each model's risk score, known security risks, Asimily's targeted mitigation recommendations, and expected device behavior. It is built on Asimily's observed risk data for medical devices in the field, including security practices learned from real deployments. With the right security controls in place, an older and more affordable model can still be safe to operate, and ProSecure helps teams make that determination before purchase.

### FDA Recalls and Security Advisories

Asimily alerts teams when FDA recalls or manufacturer security advisories affect medical devices in their inventory. Recall awareness is included with every Asimily subscription.

### Medical Device Utilization

Asimily tracks how medical devices are used, including imaging study names and durations, so clinical engineering and finance teams can plan capital expenditures with real usage data.

### Clinical Workflows

Asimily integrates with CMMS platforms used by clinical engineering teams and with healthcare technology management providers. Risk prioritization and remediation guidance account for clinical constraints, so mitigation does not interrupt patient care.

### Healthcare Recognition

Asimily IoMT Solutions was named the 2026 Best in KLAS winner for Healthcare IoT Security by KLAS Research, with an overall performance score of 96.6 out of 100. Asimily is also rated 4.9 out of 5 stars on Gartner Peer Insights in the Medical Device Security Solutions market.

## How Asimily's Approach Differs

- Prioritization drives enforcement. Asimily's ATT&CK Analysis determines whether each vulnerability is actually exploitable on a specific device in its environment, and that analysis decides which devices are segmented first and what each policy contains. The remediation list shrinks to the smallest set of actions for the same risk reduction.
- Segmentation is one of three mitigation techniques. Asimily combines segmentation with IoT Patching and targeted mitigations researched by Asimily Labs, so teams are not limited to a single method for devices that cannot be patched.
- Policy Simulation validates segmentation policy against real, observed traffic before deployment, which gives operational teams the evidence they need to approve enforcement.
- Asimily works with the NAC platforms and firewalls organizations already own, and can also enforce natively, so segmentation does not depend on any single enforcement product or require replacing existing network equipment.
- Configuration Control detects insecure configuration drift and restores devices to a known-good state, alongside inventory, prioritization, and segmentation in the same platform.
- Native packet capture is built into the platform for forensic investigation of any monitored device.
- For IoMT, ProSecure assesses medical device risk before purchase using Asimily's observed risk data from devices deployed in the field, rather than manufacturer disclosures alone.
- Agentless coverage reaches the medical, OT, and legacy devices that agent-based tools systematically miss.

### Segmentation Orchestration

What is Segmentation Orchestration?
Segmentation Orchestration is Asimily's intelligence and policy orchestration layer for network segmentation. It handles device visibility, risk prioritization, policy recommendation, policy creation, policy simulation, policy application, continuous segmentation, and policy audit. Asimily applies policy through NAC platforms, through firewalls, or natively.

Why do segmentation projects stall?
Segmentation projects stall because the intelligence needed to recommend, validate, and maintain policy rarely exists inside an organization's stack. IoT, OT, and IoMT devices often use unexpected ports, proprietary protocols, or undocumented services, so a blanket policy risks breaking critical workflows such as patient monitoring or industrial control. Teams write policies but hesitate to enforce them, and manual updates cannot keep up with network change.

Does Asimily replace my NAC?
No. Asimily works with the NAC you already run, such as Cisco ISE, Aruba ClearPass, or Arista. Most organizations have deployed a NAC but have not operationalized it for segmentation. Asimily provides the device context, prioritization, policy creation, simulation, and ongoing management that make that possible.

Does Asimily require a NAC?
No. Asimily can apply segmentation policy through a NAC, through firewalls such as Fortinet FortiGate and Palo Alto Networks Panorama, or natively. Organizations can use whichever enforcement path fits their network, or a combination.

How does Asimily make sure a segmentation policy will not break a device?
Policy Simulation validates each policy against real, observed network traffic before anything is applied. It shows exactly which devices and connections would be affected, including flows the team did not know existed. Teams can adjust a policy in simulation until the impact is acceptable and share the results with operational stakeholders before deployment.

How does Asimily decide which devices to segment first?
Asimily ranks devices by real risk using ATT&CK Analysis, which determines whether each vulnerability is exploitable on a specific device in its environment. Teams start with the small population of devices, often less than 1%, that drives the majority of risk, which shows measurable progress early instead of waiting on a network-wide project.

Does Asimily write policies in my NAC's or firewall's format?
Yes. Each NAC and firewall has its own policy schema. Policy Creation generates policies in the correct native format for the target platform, such as DACLs for a NAC, so teams do not need engineers trained on one specific platform to write them.

Is segmentation a one-time project?
No. Devices are added, retired, patched, and moved constantly, and each change can invalidate existing policy. Continuous Segmentation tracks whether policies still match the network and adapts them as it changes. Policy Audit merges, deduplicates, and optimizes policies over time to prevent the policy sprawl that can overload switches.

Can Asimily show auditors that segmentation is working?
Yes. Segmentation Orchestration produces an auditable record of enforcement effectiveness that security leaders can use in board reviews, audits, and regulatory inquiries.

What is microsegmentation?
Microsegmentation divides a network into small segments to isolate individual devices or small groups of devices. It limits lateral movement if a device is compromised. Asimily generates microsegmentation policies based on each device's observed communication behavior and risk.

How does segmentation help against AI-driven attacks?
Attackers are using AI to accelerate reconnaissance, exploitation, and lateral movement, which shortens the time between a vulnerability's disclosure and its exploitation. Devices that patch slowly or not at all are most exposed. Segmentation limits what a compromised device can reach, and continuous segmentation keeps that containment current as the network changes.

### Visibility and Deployment

Does Asimily require agents on devices?
No. Asimily is agentless. It builds its inventory from network traffic analysis, safe API-based querying where devices support it, and data from existing systems such as CMDB, CMMS, NAC, and IPAM, without installing software on devices.

Will Asimily disrupt sensitive devices?
Asimily is designed to collect data safely, without disrupting operations. In sensitive environments, collection can be passive-only. Where devices support it, Asimily adds safe, API-based querying for higher-fidelity data. Teams choose the combination that fits each environment.

How does Asimily identify devices?
Asimily uses deep packet inspection of network traffic, including industrial protocols, combined with AI and machine learning classification, Asimily's device research, and correlation with data from existing systems. It identifies each device's make, model, firmware, services, and connections.

Can Asimily see devices behind PLCs?
Yes. Through deep packet inspection of industrial protocols and custom collection where needed, Asimily can identify child devices behind PLCs and map their relationships to parent controllers.

What hardware does Asimily need?
Asimily uses collectors that receive network traffic from SPAN ports, network taps, or other sources. Options include standard appliances, small form-factor Edge processors for distributed sites, and a containerized collector that runs on Cisco Catalyst 9000 series switches.

What is a SPAN port?
A SPAN (Switch Port Analyzer) port is a switch feature that copies traffic from other ports to a monitoring port. Asimily collectors can analyze SPAN traffic to discover and classify devices without affecting the original traffic.

What is a network tap?
A network tap is a hardware device that copies traffic flowing between two network points and sends it to a monitoring tool without affecting the original flow. Asimily can use tap traffic as a data source where SPAN is not practical.

What is an Edge processor?
In Asimily deployments, an Edge processor is a collector placed at or near the network segment it monitors. Small form-factor Edge processors reduce hardware costs in distributed environments with many sites.

### Vulnerability Prioritization and Mitigation

What is ATT&CK Analysis?
ATT&CK Analysis is Asimily's proprietary method for determining whether a vulnerability is actually exploitable on a specific device in a specific environment and topology. It uses the MITRE ATT&CK framework to model the attack paths an exploit requires and checks whether those paths exist for each device.

How is ATT&CK Analysis different from CVSS scoring?
CVSS rates a vulnerability's severity in the abstract, the same way for every device. ATT&CK Analysis evaluates the vulnerability on a specific device, accounting for configuration, network position, exploit availability, and device criticality. The result is a shorter, ranked remediation list in which each item has a documented reason for its ranking.

What is the riskiest 1%?
Asimily typically finds that a small population of devices, often less than 1%, drives the majority of an organization's connected device risk. Addressing those devices first produces the most risk reduction for the effort spent.

What if no patch is available for a vulnerable device?
Many IoT, OT, and IoMT devices cannot be patched quickly or at all. Asimily recommends compensating controls: segmentation that blocks the attack path the vulnerability requires, targeted mitigations such as disabling an unneeded service, and configuration hardening. These reduce risk while preserving device function.

How often should vulnerabilities be reprioritized?
Continuously. Exploits can appear within hours of a vulnerability's disclosure. Asimily updates risk scores as new vulnerabilities, exploits, and patches emerge and as device behavior changes.

What is Risk Simulator?
Risk Simulator models the risk reduction of a proposed action, such as segmentation, patching, or a targeted mitigation, before the team executes it. It helps teams with limited capacity choose the actions with the most impact.

What are common IoT device vulnerabilities?
Common IoT vulnerabilities include default or weak passwords, outdated firmware, weak authentication, insecure data transfer and storage, unnecessary open services, and lack of central device management.

### IoT Patching

Why is IoT patching hard?
Every manufacturer has its own firmware update method, often requiring proprietary management software, and some devices need special handling, such as preserving cluster failover on networking equipment. Manual patching across many manufacturers is slow, which leaves exposure windows open.

How does Asimily make IoT patching easier?
Asimily normalizes the firmware update process so updates look the same across all supported manufacturers, while Asimily handles each manufacturer's specific steps. Updates are agentless and can run per device, on a schedule, in bulk, or automatically.

What does IoT Password Management do?
IoT Password Management stores device credentials securely, replaces default, reused, and weak passwords, and lets patching run on the team's schedule using those stored credentials.

### Threat and Response

How does Asimily detect threats on connected devices?
Asimily continuously monitors device behavior against expected patterns and more than 100 threat intelligence sources. It alerts on activity such as connections to unfamiliar servers, unusual data volumes, or protocols a device has never used.

What actions can Asimily take when it detects a threat?
Responses range from alerts and SIEM notifications to blocking specific services or ports to NAC-enforced quarantine of the affected device.

Can I write my own detection rules?
Yes. Asimily includes pre-populated rules from Asimily Labs and a wizard-based rule builder that requires no programming.

How does packet capture help incident response?
Asimily can capture packets from any monitored device on demand, giving incident responders the forensic data they need without deploying separate capture tools. Combined with device timelines, this shortens investigations and limits blast radius.

How is threat detection for connected devices different from EDR?
EDR detects and responds to threats on devices that can run an agent. Most IoT, OT, and IoMT devices cannot run one. Asimily detects threats at the network level, which covers devices that EDR cannot reach.

### Governance, Risk, and Compliance

Which compliance frameworks does Asimily support?
Asimily provides mapping and evidence for frameworks including NIST CSF 2.0, HIPAA, FDA requirements, NIS2, DORA, CMMC, NERC CIP, PCI-DSS, Cyberscope, CIS, and zero trust architectures.

Why do connected devices matter for compliance?
Regulations increasingly treat IoT, OT, and IoMT devices like IT infrastructure. For example, the HIPAA Security Rule update proposed by the US Department of Health and Human Services in January 2025 would require a written technology asset inventory, a network map of how ePHI moves, and network segmentation. The inventory would cover medical devices that handle ePHI.

What is Configuration Control?
Configuration Control records each device's hardened, known-good configuration, including its network neighbors, detects insecure drift as it happens, and supports restoring the device to its known-good state. Device timelines help determine whether a change was malicious or accidental.

What reports does Asimily provide for audits?
Asimily provides device inventories, device histories, change records, risk scores over time, segmentation enforcement records, and data export, so teams can respond to current audit requirements and to new ones as they emerge.

### IoMT

What is ProSecure?
ProSecure is Asimily's IoMT-only pre-purchase risk assessment capability. Healthcare teams look up medical devices before procurement and see each model's risk score, known security risks, recommended mitigations, and expected behavior, based on Asimily's observed risk data for medical devices in the field rather than manufacturer disclosures alone.

How do I know if a medical device in my environment has been recalled?
Asimily alerts teams when FDA recalls or manufacturer security advisories affect medical devices in their inventory. Recall awareness is included with every Asimily subscription.

How does Asimily protect medical devices without interrupting patient care?
Asimily's inventory is agentless and captured without disrupting operations, mitigation guidance accounts for clinical constraints, and Policy Simulation shows exactly which devices and connections a segmentation policy would affect before it is applied.

Does Asimily integrate with clinical engineering systems?
Yes. Asimily integrates bidirectionally with CMMS platforms used by clinical engineering teams, keeps device records synchronized, and can create work orders for vulnerabilities and anomalies.

### Connected Device Security Fundamentals

Why can't traditional IT security protect IoT, OT, and IoMT devices?
Traditional endpoint security assumes a device can run an agent, accept regular patches, and authenticate to directory services. Most IoT, OT, and IoMT devices cannot. They have limited processing power, run proprietary firmware, use non-standard protocols, and may go years without a security update. Protection has to be applied at the network layer.

How are IoT devices protected from attackers?
The main controls are network segmentation, vulnerability prioritization and patching, behavioral monitoring, credential hardening, compensating controls for devices that cannot be patched, and continuous device discovery so that no device is left unprotected because no one knew it existed.

How do I detect whether a connected device has been compromised?
Signs include unusual network activity, connections to unfamiliar destinations, unexpected protocols or data volumes, and behavior that deviates from the device's normal baseline. Continuous behavioral monitoring at the network level is the most reliable method for devices that cannot run security software.

How should organizations protect industrial control systems?
Core practices include network segmentation, strict access controls, firmware updates where operationally feasible, safe monitoring of ICS network traffic, and intrusion detection. Because ICS equipment is often fragile and runs legacy software, monitoring should not disrupt production, and compensating controls are essential where patching is not possible.

What is OT asset management?
OT asset management is the practice of identifying, monitoring, and maintaining the operational technology assets in industrial and critical infrastructure environments, including PLCs, SCADA systems, and their connected devices. An accurate, continuously updated OT inventory is the starting point for securing those assets.

How should organizations respond to a cyberattack involving connected devices?
Effective response includes an incident response plan, clear communication protocols, capturing traffic from suspicious devices, isolating affected devices, analyzing the attack, remediating, and improving the plan afterward. Many organizations keep a specialist incident response firm on retainer.
