OT security has entered a new phase.
The convergence of industrial systems with IT, OT and cloud has created an attack surface that is broad, fast-moving, and deeply consequential. Visibility gaps are no longer tolerable when a single unpatched controller or connected sensor can halt production, disrupt energy grids, or impact patient safety.
That's why Armis Centrix™ and Fortinet's Security Fabric have integrated their platforms at eight critical control points, thus creating a unified, data-driven approach to exposure management and defense. The result is a closed-loop system that continuously discovers, prioritizes, and protects every asset that keeps your business running.
Seeing What Others Miss
Armis Centrix™ identifies and classifies every device across OT, IT, IoT, and IoMT environments using the industry's largest asset intelligence engine of over 6.5 billion device fingerprints and counting. This live, contextual insight feeds directly into Fortinet's secure networking and operations layers.
Through FortiGate firewalls, Armis ingests network traffic via PCAP streams, enabling instant device visibility without deploying new sensors. FortiManager then ingests Armis segmentation recommendations and applies them across distributed sites, enforcing Zero Trust principles. And FortiNAC ensures that rogue or unknown assets are automatically contained before they ever become a problem.
From Detection to Action
Armis and Fortinet built this integration so teams that don't have time to sift through noise. When Armis detects suspicious behavior or a vulnerable asset, it doesn't just alert, it acts.
FortiSIEM consumes that telemetry to enhance correlation and investigation across the entire attack surface, while FortiSOAR uses it to drive automated response playbooks thereby isolating devices, tightening controls, and disabling the ability for attacks to migrate through the digital landscape.
FortiAnalyzer leverages Armis risk scores and behavioral data in unified reports that give CISOs and plant operators a single view of exposure and response across sites and systems. The result is a measurable improvement in mean time to detect and remediate.
Adaptive Controls that Keep Pace with Change
Static policies don't work in dynamic OT networks. Armis Centrix™ continuously evaluates device behavior and posture, updating Fortinet's enforcement points in real time. FortiManager uses these updates to refine policies. FortiEDR ensures critical endpoints such as servers, HMIs, engineering workstations are properly protected, highlighting where coverage is missing or overlapping.
For organizations operating in hybrid environments, FortiCNAPP integrates with Armis Centrix™ to normalize, contextualize and prioritize findings across toolchains. This enrichment prevents wasted cycles and helps security teams efficiently focus on the exposures that truly matter to the business.
Segmentation and Zero Trust Done Right
The Armis–Fortinet solution goes beyond visualization to enforcement. Using real-time intelligence from Armis, FortiGate and FortiManager automatically apply segmentation rules that contain risk and minimize blast radius.
Consider a production plant where a legacy PLC can't be patched. Instead of leaving it exposed, Armis identifies it, classifies its behavior, and triggers FortiGate to enforce compensating controls which isolates that PLC within milliseconds if it exhibits suspicious activity. This is what Zero Trust looks like when it's operationalized.
Built for Operational Resilience and Compliance
Every sector faces its own standards such as IEC 62443 in manufacturing, NIST 800-82 in energy, HIPAA and FDA guidance in healthcare. The joint Armis–Fortinet solution aligns with these frameworks by providing the visibility, context, and enforcement needed to demonstrate continuous compliance coupled with operational. Security teams can see where vulnerabilities intersect with critical processes and implement safeguards without halting operations. For organizations where uptime equals safety or revenue, this alignment is crucial.
Eight Integrations. One Unified Defense.
This partnership is about measurable key business outcomes. It reduces mean time to visibility, accelerates containment, and allows security teams to deploy Fortinet controls with surgical precision using Armis intelligence. When every second matters and every asset counts, Armis and Fortinet deliver the visibility, security, and resilience that modern OT environments demand while also ensuring the speed of business operations.
