Best Claroty Alternatives: 2026 Guide
Updated November 2, 2026. Asimily publishes this guide and is one of the platforms compared.
The top Claroty alternatives for 2026 are Asimily, Armis, Dragos, Forescout, Microsoft Defender for IoT, Nozomi Networks, Ordr, and Tenable. Asimily fits teams that need exploitability-based prioritization and enforced segmentation across IoT, OT, IoMT, and IT. Nozomi Networks and Dragos fit OT-heavy industrial sites, Armis fits ServiceNow-centric teams, and Forescout fits teams that want their device security platform to be their NAC.
For many security teams, the next Claroty renewal comes in a year when three of its best-known competitors changed hands: Mitsubishi Electric acquired Nozomi Networks in January 2026, ServiceNow acquired Armis in April 2026, and Accenture took a majority stake in Dragos in September 2026. That makes it a practical moment to confirm that your connected device security platform, partner, and future roadmap still match what your program needs. For many, that’s an accurate inventory, a short list of the devices that actually put you at risk, and a reliable path from that list to reduced risk for your entire IoT, OT, IoMT, and IT attack surface.
This guide covers what to evaluate in a Claroty alternative, compares the platforms security teams most often shortlist, and explains where Asimily fits for teams that need to close exposures without disrupting operations.

Why Claroty Customers Are Weighing Their Options
Claroty itself has not changed hands in 2026, but its market has. Claroty remains independent: it raised a $150 million Series F in January 2026 (SecurityWeek) and was named a Leader in the 2026 Gartner Magic Quadrant for CPS Protection Platforms for the second year (Claroty). Mitsubishi Electric completed its acquisition of Nozomi Networks on January 28, 2026 (Business Wire). ServiceNow completed its acquisition of Armis on April 20, 2026 (Verdict). Accenture’s majority investment in Dragos closed in September 2026 (SecurityWeek).
For organizations already standardized on Claroty, those changes may matter little. For others, a renewal is a reasonable time to ask a few practical questions:
- How will packaging and pricing change as Nozomi Networks, Armis, and Dragos move into larger portfolios?
- Does the platform you shortlist now depend on running its new parent’s other products?
- Where does connected device security, especially OT and medical device coverage, sit on each vendor’s roadmap?
- Where will investment dollars flow within the new parent companies, toward or away from these platforms?
They are the same questions any team should ask when a core security vendor, or its market, changes ownership, and they are easier to answer with a comparison already in hand.
Why Teams Evaluate Claroty Alternatives
Beyond market changes, security teams actively evaluate alternatives to Claroty for several practical product and operational reasons:
- High remediation volume: Claroty’s products in healthcare and OT prioritize vulnerable devices but do not analyze whether an attacker has a path to each vulnerability in the customer’s environment, based on Asimily’s October 2026 comparison.
- Enforcement limitations: Claroty creates and applies macro segmentation policies to NACs and firewalls, but does not simulate NAC policy against live traffic, provide a pre-deployment enforcement plan, or adapt policy continuously as devices change, per the same comparison.
- Mitigation beyond segmentation: Claroty integrates with patch management tools but does not patch IoT devices or snapshot device configurations for recovery, per the same comparison.
What to Evaluate in a Claroty Alternative
When evaluating connected device security platforms, eight key criteria help security leaders distinguish capabilities during vendor selection.
| Criterion | Why It Matters |
|---|---|
| Deployment Model | Many IoT, OT, and medical devices cannot run agents or tolerate aggressive scanning. Confirm the platform builds a complete inventory agentlessly, safely, and without disruption. |
| Exploitability Analysis | Generic CVSS scoring produces lengthy lists. More than 48,000 CVEs were published in 2025 alone (2025 CVE Data Review). Does the platform analyze actual network context (especially topology) to determine which vulnerabilities are genuinely exploitable on a specific device? |
| Path to Enforcement | A recommendation is not a control. Check whether the platform creates, simulates, applies, and maintains policy, and through which enforcement points: NAC, firewall, or natively. |
| Mitigation Beyond Segmentation | Some devices can be patched, some can only be reconfigured, and some can only be contained. Look for automated patching, configuration drift control based on snapshots, and targeted mitigations alongside segmentation. |
| Industrial Protocol Depth | Deep industrial protocol coverage is one of Claroty’s core strengths. If your environment is mostly PLCs, DCS, and safety systems, confirm each alternative decodes the protocols your plants actually run. |
| Fit With Your Existing Stack | The platform should work with the NAC you already own, such as Cisco, Aruba, Arista, or Extreme, along with your firewalls, SIEM, and ITSM tools. |
| Vendor Strategy and Focus | Is connected device security the core focus of the vendor’s roadmap, or a secondary module within a broader IT suite? |
| Pricing Transparency and Model | How is licensing structured (e.g., per-device count vs. site licenses), and are quotes predictable as device counts grow? |

| Tenable | Hybrid IT/OT environments needing unified vulnerability management | Hybrid active querying and passive monitoring integrated into Tenable One | Deep integration with IT vulnerability management workflows and active PLC querying |
| Microsoft Defender for IoT | Organizations heavily invested in Microsoft XDR and Sentinel SIEM | Agentless network sensors feeding into Microsoft Defender XDR and Sentinel | Native integration across Microsoft security tools, Defender portal consolidation, and Azure threat intelligence |
| Forescout (Vistaro) | Enterprises that want their device security platform to also be their NAC | Agentless, with more than 30 discovery methods | Access control, segmentation, and discovery from a single vendor with a long NAC history |
Asimily’s Approach: From Risk Intelligence to Enforced Policy
Asimily is the Proactive Cyber Asset Defense Platform empowering teams to reduce risk across their entire attack surface, including IoT, OT, IoMT, IT, software, services, applications, middleware, and AI workloads. Asimily maps the attack surface, identifies and prioritizes the riskiest assets, and continuously delivers segmentation and risk mitigation options. It builds an agentless, continuously updated inventory of every connected asset safely without operational disruption. It deploys in the cloud or on premises and enforces segmentation through the NACs and firewalls a team already runs. Using patent-based ATT&CK Analysis, Asimily isolates the 1% of devices driving the vast majority of actionable risk by evaluating specific network topology and real-world exploitability.
From there, Asimily closes exposures (or recommends closures) with the right technique for each device: segmentation, patching, or a targeted mitigation drawn from Asimily Labs’ work and the ATT&CK Analysis of exploitability. More practically, Risk Simulator models the risk reduction of an action before a team commits to the time and effort needed. For segmentation, Asimily recommends, creates, simulates, and enforces policy through NACs such as Extreme, Cisco ISE, Aruba ClearPass, and Arista. Policies stay matched to intent rather than relying on static ACLs that quickly go stale.
| Capability | What It Does |
|---|---|
| Inventory and Visibility | Agentless discovery and classification of every IoT, OT, IoMT, and IT asset, including services, connections, and firmware versions (for relevant devices). |
| ATT&CK Analysis | Determines real exploitability per device and network, producing the smallest remediation list for the same risk reduction |
| Policy Auto-Recommendation and Policy Creation | Shows where to start and generates policy in each NAC’s native format |
| Policy Simulation | Validates a policy against real, observed network traffic and shows exactly which devices and connections would be affected before anything deploys |
| Continuous Segmentation and Policy Audit | Keeps policy aligned as devices are patched, moved, added, or decommissioned, and merges, deduplicates, and optimizes policies to prevent sprawl and overtaxing of limited switch memory |
| IoT Patching | Applies fixes where devices can be patched, manually or automatically. |
| Configuration Control | Detects configuration drift and restores from known, valid snapshots. |
| Threat and Response | Anomaly detection with protective actions up to quarantine, plus native packet capture for forensic incident response |
| Governance, Risk, and Compliance | Compliance mapping to frameworks including NIST, CIS, NIS2, and CMMC (among many others), with an auditable record of enforcement for audits and board reviews |
Additionally, Asimily won the Operational Technology and Industrial IoT Security category in the 2026 Merit Awards.
Frequently Asked Questions
What Are the Top Claroty Alternatives for 2026?
The leading alternatives to Claroty in 2026 include Asimily, Armis, Dragos, Forescout, Microsoft, Nozomi Networks, Ordr, and Tenable. They fall into four groups: OT specialists (Asimily, Nozomi Networks, and Dragos), broad asset intelligence and vulnerability platforms (Asimily, Armis, Microsoft, and Tenable), a NAC-based platform (Forescout), and platforms that carry findings through to enforced mitigation (Asimily and Ordr).
How Did Claroty’s Competitors Change in 2026?
Three of Claroty’s main competitors changed ownership in 2026: Mitsubishi Electric completed its acquisition of Nozomi Networks in January, ServiceNow completed its acquisition of Armis in April, and Accenture’s majority investment in Dragos closed in September. Claroty itself remains independent. Teams reviewing Claroty are weighing how those new owners may shape each platform’s roadmap and packaging.
Why Do Security Teams Replace Claroty?
Teams often consider alternatives when they need vulnerability prioritization based on exploitability in their own environment, segmentation policy that is simulated against live traffic before enforcement, or remediation beyond segmentation, such as IoT patching and configuration snapshots. Others want a vendor whose roadmap delivers relevant features quickly, which matters more as attackers use AI to move faster.
Do Claroty Alternatives Require Software Agents?
No. Leading alternatives, including Asimily, can discover connected devices without installing endpoint agents, using passive network traffic analysis, native switch integrations, and API integrations to identify and secure devices without risking device disruption.
How Does Asimily Compare With Claroty?
Asimily and Claroty both discover IoT, OT, and IoMT devices agentlessly. Asimily adds per-device exploitability analysis, segmentation policy simulated against live traffic, IoT patching, and configuration snapshots.
What Does Switching From Claroty Involve?
Switching from Claroty usually happens in stages. Run the new platform in parallel to compare device counts and classification, then build segmentation policy from observed traffic rather than copying old rules, and finally move SIEM, NAC, and ITSM integrations before retiring the old platform. Asimily’s Policy Simulation lets teams validate new policy against live traffic before anything is enforced.
Choosing the Right Claroty Alternative
Start with your riskiest devices, not a vendor’s feature list. Ask each finalist to show which devices in your environment carry exploitable risk, why each one is ranked where it is, and what it would take to contain them. Ask how they determined that a vulnerability is exploitable: from a generic score, or from analysis of your own network topology?
Then test the path to enforcement. Ask each finalist to show the impact of a proposed policy against your observed traffic before anything changes, using your own NAC, and to explain how that policy stays current as devices move and change. Your IT, OT, and facilities colleagues will want that answer before they agree to any enforcement.
Ask for a past and future roadmap to show you how quickly new capabilities have been developed and will be developed going forward.
