Illumio has expanded its strategic partnership with Armis, deepening integration between their respective platforms as organisations grapple with securing converged IT and operational technology (OT) environments.
The collaboration links Illumio’s segmentation and breach containment capabilities with Armis’ cyber exposure management platform, creating a combined approach aimed at improving visibility and limiting lateral movement across mixed IT, OT and IoT networks.
The announcement reflects growing demand for integrated security controls in environments where traditional IT systems intersect with industrial control systems, manufacturing equipment and other operational technologies. As digital transformation accelerates across critical infrastructure sectors, these environments have become increasingly interconnected — and increasingly exposed.
Armis specialises in asset discovery and classification, including unmanaged and legacy devices that often sit outside standard endpoint management frameworks. Under the expanded partnership, Armis’ asset intelligence feeds into the Illumio platform to improve network mapping and identify segmentation opportunities based on risk context.
Illumio’s microsegmentation capabilities are designed to limit the spread of threats once detected, enforcing containment policies that restrict lateral movement between systems. The integration allows automated segmentation actions when anomalies are identified, linking visibility and enforcement more closely.
From a security operations perspective, telemetry from both platforms can be integrated into SIEM and SOAR workflows, supporting investigation and response processes within existing SOC environments.
The move comes amid sustained regulatory pressure on operators of critical infrastructure to strengthen cyber resilience. Frameworks such as NERC CIP, IEC 62443 and NIST 800-82 emphasise asset visibility, segmentation and risk-based controls in industrial environments. Vendors are increasingly positioning integrated platforms as a way to simplify compliance while reducing operational risk.
Converged IT/OT environments present distinct challenges. Legacy industrial systems often cannot be easily patched or replaced, and downtime can carry safety and economic consequences. As a result, segmentation and containment strategies are often prioritised over traditional prevention-based approaches.
The partnership also includes closer alignment of sales and go-to-market efforts, signalling an attempt to compete more directly in the critical infrastructure and industrial cybersecurity space, where platform consolidation is accelerating.
While integration between visibility and enforcement tools is not new, the continued convergence of IT and OT networks is reshaping security architecture decisions. Organisations are under pressure to understand what is connected, prioritise risk effectively and contain breaches quickly — particularly in sectors where disruption affects public safety and essential services.
The Illumio–Armis integration is now available globally for joint customers, as vendors continue to position combined asset intelligence and segmentation as a foundation for Zero Trust architectures in industrial and hybrid environments.
