Introducing Asimily’s Segmentation Orchestration: AI-Driven Proactive Segmentation

Most organizations have some segmentation in place. Almost none have segmentation that works. According to Cisco’s 2025 Segmentation Report, 79% of security leaders say segmentation is a top priority – yet only 33% have fully implemented it, and 87% say their process needs improvement. The reason isn’t a lack of intent. It’s that segmentation projects routinely stall in pilot because the intelligence required to recommend, simulate, and continuously adapt policy doesn’t exist inside most organizations’ stacks. Meanwhile, attackers are adopting AI-driven techniques to accelerate reconnaissance, exploit vulnerabilities, and move laterally — exploiting exactly the gaps that stalled segmentation leaves open.

Introducing Segmentation Orchestration from Asimily: your line of defense against AI-driven cyberattacks. With Segmentation Orchestration, organizations gain a scalable approach to segmentation initiatives, eliminating the multi-quarter analyst effort that stalls most segmentation projects, reducing operational costs, and improving policy accuracy and safety. Segmentation Orchestration is the only solution on the market today that combines complete asset visibility, vulnerability prioritization, and segmentation orchestration on top of existing NACs, Firewalls and other infrastructure – unlike point tools that address only one of these functions in isolation.

Why Traditional Segmentation Approaches Fall Short

Modern enterprise networks are dynamic and complex, consisting of various devices with different protocols and security capabilities. Few organizations maintain a purely flat network. Most implement some segmentation, yet the policies fail to remain effective as the network evolves. IT and networking teams face several major challenges, including:

• Limited visibility into devices, communications, and data flows.
• Difficulty prioritizing which assets and vulnerabilities represent the greatest risk.
• Fear of breaking the network with complex segmentation policies.
• Inability to simulate policy changes before deployment.
• Manual policy application is error-prone and time-consuming.
• Constantly reacting to new devices, configuration changes, and evolving threats.
• Little guidance on where segmentation efforts will have the greatest security impact.
• No continuous auditing or validation to ensure policies still meet their intended purpose.

Many organizations struggle to operationalize segmentation efforts because they use traditional approaches that rely heavily on access control lists (ACLs) that become outdated or overridden by newer rules. Networking teams must navigate complex policy languages and manually update controls across thousands or hundreds of thousands of devices. Meanwhile, attackers increasingly leverage automation and AI-driven tactics to accomplish their objectives.

Ultimately, organizations collect multiple tools, creating a fragmented view of their environments while still struggling to reduce risk.

8 Ways That Asimily’s Segmentation Orchestration Solution Reduces Exposure

With Asimily, organizations can transform segmentation from a one-time deployment project into a continuously managed and intelligently-orchestrated security operation. Segmentation Orchestration provides prescriptive recommendations to establish, maintain, and progressively mature segmentation initiatives so that organizations can build true proactive and responsive segmentation strategies.

1. Gain Complete Visibility into Every Connected Asset

Most IT and networking teams struggle to understand the devices connected to their network. Without visibility into devices, their connections, and data flows, the teams must make imprecise decisions about what to segment and how to do it.

With Asimily, teams gain deep discovery and device classification across IT, OT, IoT, and IoMT environments, enabling organizations to understand exactly which devices are communicating, how they interact, and where the greatest risks exist. By using Asimily’s analysis of real network traffic, behavioral patterns, and integrations across the network, organizations can identify exploitable vulnerabilities and contextualize risk based on actual business impact, enabling network teams to make informed segmentation decisions rather than relying on static assumptions.

Asimily’s platform:

• Ingests data across networking infrastructure, NAC, NetFlow/sFlow, IPAM, vulnerability management, EDR, device management, CMMS/CMDB, and other tools — without requiring agents on devices.
• Deploys on switches for active and passive collection.
• Engages in deep packet inspection plus Asimily’s research data to identify exact device make, model, firmware, and behavior.
• Maps device-to-device communication patterns across the network, like communication between PLCs and SCADA controllers.
• Continuously inventories updates as devices appear, disappear, change firmware, or shift behavior.
• Acts as a single source of truth that becomes the input to every downstream segmentation policy.

2. Prioritize Segmentation Efforts Based on Real Risk

When organizations manage tens or hundreds of thousands of connected assets, manually determining where to begin segmentation efforts is nearly impossible. Often, the resulting segmentation policies consume significant operational effort while delivering minimal security value.

Asimily’s Segmentation Orchestration identifies the riskiest cyber assets and prioritizes segmentation actions based on:

• Vulnerabilities that are relevant in the given network
• Device criticality
• Manufacturer context
• Real-time risk intelligence
• Attack path exposure

Security and networking teams can focus their segmentation based on devices and communication paths that present the highest compromise risks, improving the initiative’s effectiveness while reducing operational burdens.

Asimily’s platform:

• Pinpoints devices that can be exploited in each environment using Asimily’s proprietary ATT&CK Analysis, not generic CVSS.
• Auto-prioritizes based on real-time risk and exploit availability, asset criticality, and reachability.
• Identifies the small population of devices, often less than 1%, that drive the majority of segmentation urgency.
• Maps each prioritized attack vector to the specific NAC or Firewall policy that contains it.
• Updates risk scoring as patches land, exploits emerge, or device behavior changes.
• Provides defensible, auditable evidence for why each high-risk device received the policy it did.

3. Automatically Recommend High-Impact Segmentation Policies

When building segmentation policies, many security and network teams rely on a trial-and-error approach that becomes overwhelming in large, complex environments.

For automatically-generated, precise, conflict-free NAC or Firewall policies, teams can use Asimily’s Segmentation Auto-Recommendation Capabilities that eliminate uncertainty by incorporating:

• Network topology
• Device type
• Communication behavior
• Optional risk prioritization

With intelligent policy recommendations, security and networking teams can:

• Accelerate segmentation initiatives
• Reduce policy conflicts
• Improve policy accuracy
• Prioritize the highest-risk exposures first
• Minimize operational complexity

Network segmentation initiatives can move forward with confidence by implementing policies that will have the most significant impact on their risk posture.

Asimily’s platform:

• Creates error-free, precise policies based on complete device and network context
• Detects every new device joining the network and proposes the correct policy automatically.
• Streams continuous policy updates into security policy tools so enforcement never lags reality.

4. Simulate Policies Before Deployment

Many teams struggle with uncertainty that prevents them from understanding how a change will impact the network, often forcing them to slow down their initiative or avoid segmentation.

With Asimily’s Policy Simulation capabilities, security and networking teams can preview the segmentation policy’s operational impact before enforcing it. Before deploying changes into production, teams can use Asimily to evaluate:

• Potential communication disruptions
• Policy conflicts
• Operational dependencies
• Segmentation effectiveness

With insight into potential operational issues, organizations can minimize service outages or business disruption while improving their security.

Asimily’s platform:

• Simulates each policy against real, observed device communication, not synthetic test traffic.
• Surfaces every flow that would be blocked, including flows that the organization’s team did not know existed.
• Identifies operational dependencies that would break under a proposed policy.
• Allows teams to iterate on a policy in simulation until the impact is acceptable, then push to security policy tools.
• Eliminates the “we wrote the policy, but we are too afraid to enforce it” deadlock.
• Provides simulation evidence to operations and clinical or industrial stakeholders before go-live.

5. Create Intelligent Policies that follow the format of the NAC or Firewall

Once the policy has been agreed upon, network teams have to write precise policies in the language of the NAC or Firewall. This can become a challenge as every NAC and FIrewall has its own format in which policies have to be written. An error in the policy can lead to an adverse outcome

Asimily’s Smart Policy Management capabilities simplify segmentation orchestration by intelligently generating segmentation policies in the right format. With Asimily’s policy engine,   Asimily creates the policy in the language of the NAC or Firewall, ensuring precise, error-free policies that work as intended 

Asimily’s platform:

• Writes precise, fine-grained policies that are in the language of the NAC or Firewall 
• Identifies conflicts and overlaps before policies are pushed to security policy management tools.
• Removes the multi-quarter analyst effort that currently blocks segmentation rollouts.

6. Apply Policies to NAC / Firewall

The nuance of actually applying a policy to a NAC / Firewall is intricate and complex, at best. Not to mention the added complexity that each unique vendor brings to the table.

Asimily leverages APIs and capabilities built with the NAC or Firewall vendor to apply the policies directly on the NAC or Firewall. This automation layer eliminates the need for security and network teams to apply them manually, which comes with the added burden of human error and potentially breaking the network.

Asimily’s platform:

• Communicates with each unique NAC / Firewall vendor via built-in capabilities or direct APIs.
• Applies each policy directly to ensure error-free implementation, at scale.
• Removes the complexity of manual policy application, reducing the burden on security and network teams.

7. Continuously Adapt Segmentation to Network Changes

Many segmentation initiatives fail because they rely on static policies that require continuous manual intervention as new devices appear, configurations change, vulnerabilities evolve, and attack paths shift.

Asimily’s Continuous Segmentation capabilities proactively apply policies based on dynamic criteria rather than static device lists. As the network changes, Asimily continuously adapts segmentation policies based on:

• Device behavior
• Risk posture
• Configuration changes
• Newly discovered assets
• Network Topology 

With automation that responds to changes, IT and networking teams can focus on strategic business initiatives while still mitigating risk effectively.

Asimily’s platform:

• Reacts to firmware changes, vulnerability disclosures, and behavior shifts with policy updates.
• Identifies devices whose risk profile has changed enough to require policy re-tiering.
• Maintains policy alignment with original intent as the environment grows and changes.
• Streams continuous policy updates into the NAC or Firewall so enforcement never lags reality.
• Replaces the periodic-review model with always-current segmentation.

8. Continuously Audit, Optimize, and Demonstrate Policy Effectiveness

Often, organizations have little visibility into whether their policies continuously achieve the desired security objectives, as policy drift, conflicting rules, and environmental changes can reduce segmentation effectiveness.

Using Asimily’s Policy Audit capabilities, organizations can continuously evaluate segmentation policies for:

• Errors
• Inconsistencies
• Policy conflicts
• Preventing Policy Sprawl 
• Drift from original intent

Asimily automatically recommends optimized policies to improve segmentation outcomes while minimizing operational disruption, enabling organizations to maintain effective segmentation without overwhelming networking teams with manual policy management. Critically, the continuous audit process produces an auditable evidence trail — giving security leadership defensible documentation for compliance reporting, board-level security reviews, and regulatory inquiries that demonstrates segmentation is working as intended.

Asimily’s platform:

• Looks at every policy present in the network
• Evaluates if the policies are working without errors
• Evaluates if the policies are still needed or are redundant based on changing device and network configuration
• Evaluates if multiple policies can be combined to create a single policy that is more effective in reducing risk. 

What the Data Says About Segmentation Initiatives

Security and networking teams work tirelessly to reduce exposures, improve compliance, and mitigate data breach risks. In theory, network segmentation acts as a core security control. Realistically, it has become increasingly difficult to maintain and operationalize segmentation. According to Cisco’s 2025 Segmentation Report, segmentation remains a high-priority security control, yet few have fully executed their strategies:

• 79% say that segmentation is a top priority for their organization.
• 33% have fully implemented both macro- and micro-segmentation.
• 87% agree that their process of segmentation needs improvement.

For the 87% percent that need improvement, the two biggest challenges professionals face are environment complexity and lack of visibility.
