Illumio - Experts & Thought Leaders

Agentic AI is fundamentally changing the scale, speed, and sophistication of cyberattacks—increasing lateral movement, exposing the limits of fragmented, asset-centric security, and accelerating the asymmetry of cyber warfare. In response, Illumio Inc. is changing how breach containment works, shifting from protecting workloads in isolation to a system-wide approach that continuously reveals how attacks move end-to-end and where and how they must be stopped. AI security graph Illumio is delivering new enhancements to Illumio Insights that fundamentally expand how lateral movement risk is exposed and mitigated, anchored by the introduction of Network Posture. By further enriching its AI security graph, Illumio now delivers system-wide, real-time visibility across hybrid, multi-cloud, and OT environments, surfacing end-to-end attack paths and showing where risk must be prioritised and mitigated. In an era where AI agents traverse enterprise infrastructure autonomously and at machine speed, the ability to see and control lateral movement has become existential. Continuous measurement of security Network Posture analyses live network traffic, policy intent, and enforcement alignment against industry security frameworks to identify where lateral movement risk exists — including exposures that may not yet be actively exploited. By correlating these findings with application and business context, teams can prioritise breach containment and segmentation decisions based on real, system-level risk rather than static assets or point-in-time assessments. Network Posture also provides continuous measurement of security posture across hybrid environments, supporting clear reporting on maturity and alignment with frameworks such as NIST CSF, PCI DSS, SOC 2, and DORA based on how the network is behaving. Traditional IT infrastructure “Most security failures happen because teams don’t understand how things are connected,” said John Kindervag, Chief Evangelist at Illumio. “Attackers exploit relationships, not individual assets. If you can’t see how traffic flows throughout your environment, you can’t see the attack and contain the breach. We’re approaching an ‘AI event horizon’ in cyber, where the attacker advantage becomes nonlinear, and defenders can’t keep up by chasing alerts alone. When prevention and detection fall short, the last line of defense remains breach containment.” “Organizations still treat Zero Trust like a shopping list — buy more stuff, feel better, hope it works,” said Dr. Chase Cunningham (DrZeroTrust). “Agentic AI is going to punish that mindset. The only measures that matter are outcomes: how often you get hit, how far the attacker can move, and how fast you can contain. That requires understanding how systems connect and how risk propagates because you can’t defend what you don’t understand, and you can’t contain what you can’t see.” Expanded context for OT environments Extends risk analysis beyond traditional IT infrastructure by incorporating OT system inventory, context, and traffic. By enriching attack path analysis with OT visibility through integrations such as Armis, teams gain a clearer understanding of exposure and can prioritise containment and segmentation decisions based on real operational risk across their entire interconnected OT and IT environments. Delivers agentless visibility into private data centers to expose lateral movement risk and attack paths across on-prem and cloud environments, and connects those insights directly to enforcement through integrations with Fortinet and Check Point, and other leading firewalls. This makes it even easier and provides greater flexibility for customers wishing to prioritise breach containment. Accelerated SOC investigation and response Shifts SOC investigations from isolated alerts to attack path awareness by correlating identity, vulnerability, and traffic relationships across the environment. Analysts can see how activity propagates through the system and act on the paths that pose the greatest risk - directly within existing SIEM and ticketing workflows.

Illumio, Inc., the breach containment company, announces an expanded partnership with Armis, the cyber exposure management & security company, to protect converged information technology (IT) and operational technology (OT) environments with deeper insights into risk and coordinated market strategies. The joint offering combines the Illumio Platform—featuring Illumio Insights and Illumio Segmentation—with Armis Centrix™, Armis’ Cyber Exposure Management Platform. Together, they enable businesses to detect threats earlier, automatically contain breaches, and embed resilience into their most vulnerable systems. Most vulnerable systems “Securing the entire attack surface starts with knowing what’s connected and where risk lives,” said Nadir Izrael, CTO and Co-Founder, Armis. “This partnership unifies visibility, asset intelligence, and enforcement. Together, we empower organizations to act decisively, stopping threats before there’s any impact and keeping critical operations resilient.” Illumio breach containment, combined with Armis’ continuous cyber exposure management and security capabilities, creates a unified Zero Trust security approach for converged IT and OT environments. With the addition of Illumio Insights, the relationship between Armis and Illumio extends beyond segmentation, evolving into a native capability that simplifies operations and enables proactive containment. High-impact segmentation Integration Highlights: Comprehensive Asset Visibility: Armis discovers and classifies all IT, OT, and IoT devices—including unmanaged and legacy assets—and shares this classification with the Illumio Platform to enhance visibility and mapping. Risk Prioritisation: Armis intelligence feeds Illumio Insights to surface high-impact segmentation opportunities. Dynamic Containment: Illumio enforces microsegmentation when Armis detects anomalies, preventing lateral movement. SOC Integration: Joint telemetry integrates with SOC workflows, SIEM, and SOAR for faster investigations. Continuous asset intelligence This collaboration enables Zero Trust across IT, OT, and IoT environments, reduces the impact of breaches through rapid containment, and supports compliance with standards including NERC CIP, IEC 62443, and NIST 800-82. “When these types of environments are compromised, it’s not just downtime—it’s safety, infrastructure, and trust at stake,” said Todd Palmer, SVP of Global Partner Sales and Alliances, Illumio. “By pairing Illumio breach containment with Armis’ continuous asset intelligence, we empower teams with insight and control to act fast and keep essential systems online.” Protecting critical infrastructure Illumio is expanding its collaboration with Armis beyond technology, aligning go-to-market strategies to make it easier for organizations to access and deploy advanced Zero Trust Security solutions. Joint sales and marketing efforts ensure that customers benefit from seamless integration, expert guidance, and a unified approach to protecting critical infrastructure.

FireMon, the foremost network security and firewall policy management company, announced the general availability of its integration with Illumio, giving organizations operational control over both microsegmentation and traditional firewall policies from a single platform. Zero Trust adoption risks lie at the point of implementation. Policy conflicts between segmentation and firewall rules stall deployments, leaving even strong designs incomplete and unenforced. These conflicts are not visibility gaps, but governance gaps caused by disconnected policy models across enforcement domains. FireMon solves this problem by unifying Illumio policies and firewall rules in a single place, enabling teams to detect and resolve conflicts automatically and to move Zero Trust initiatives from prototype to production. Strong security and compliance “Effective Zero Trust governance depends on consistent compliance and unified policy management across all enforcement points,” said Todd Palmer, SVP of Global Partner Sales and Alliances at Illumio. “FireMon’s integration with the Illumio Breach Containment Platform enables the first truly unified approach to analyzing and managing both microsegmentation and firewall policies. Together, the platforms provide stronger security and compliance, streamline reporting, and enable transparent auditing, accelerating organizations’ Zero Trust maturity.” Operational management Unlike point integrations that stop at application visibility, the FireMon–Illumio integration delivers true operational management. By consolidating policy governance and changing workflows, FireMon bridges the gap between network and workload segmentation, eliminating blind spots, reducing manual review, and ensuring consistent enforcement across hybrid environments. The result is a Zero Trust architecture that finally works as designed enabling enterprises to successfully adopt zero trust by bringing policy consistency, visibility, and control. Application driven connectivity “Application discovery has real limits in dynamic, non-deterministic environments,” said Jody Brazil, CEO and cofounder of FireMon. “As workloads move and identities change across cloud and on-prem, discovery alone can’t keep up. That’s why intent-based approaches like Illumio are so effective. Our integration brings that intent together with unified policy governance, giving organizations a practical way to support application-driven connectivity while managing enterprise complexity across hybrid environments.” Steps to evaluate the integration Organizations can begin evaluating the FireMon–Illumio integration immediately through the following options: Explore the FireMon–Illumio Zero Trust partnership Watch FireMon CEO Jody Brazil and Zero Trust creator John Kindervag explain the integration Attend an upcoming joint FireMon–Illumio product webinar See the integrated solution in a video demonstration

Trevor Dearing, the EMEA Director of Critical Infrastructure Solutions at Illumio, said “It is encouraging to see NIST releasing updated guidance acknowledging the increase in cyber-attacks targeting the supply chain and the consequent necessity to bolster the supply chain’s cyber security. We can no longer turn a blind eye to the exponential increase in attacks on the IT systems of manufacturers, logistics companies and organizations, which ultimately target the operational part of the business.” Cyber-attacks have real-world impacts Cyber-attacks that disrupt the logistics or manufacturing process can have immediate real-world impacts" He adds, “The truth is threat actors have realized they can increase efficiency and profitability, by compromising a single product, knowing it will have impact downstream on companies who use it.” Trevor Dearing continues, “Moreover, cyber-attacks that disrupt the logistics or manufacturing process can have immediate real-world impacts, further increasing the likelihood that any ransom demands will be met, as organizations flounder to get critical systems back up and running. The result is that supply chain attacks have increased with a vengeance.” Zero Trust approach to security He adds “A Zero Trust approach to security provides organizations with confidence in their supply chain security because by only allowing known and verified communication between environments, security teams can be sure that an attack on the IT systems will not affect the management or logistics processes.” Trevor Dearing concludes, “With the move to industry 4.0 and the adoption of cloud-connected industrial IoT (Internet of Things), the potential impact of a ransomware attack will only continue to grow. That’s why, it is important to act now and put security measures in place that will make our infrastructure resilient to attacks – even once they’ve breached our perimeter.”
