Illumio has announced major enhancements to Illumio Insights, introducing a Network Posture capability that expands how lateral movement risk is detected and prioritised across hybrid, multi‑cloud, and operational technology environments.
The move reflects a wider industry response to the speed and complexity of agentic AI‑enabled attacks that blur traditional network boundaries and demand faster containment strategies.
Illumio’s enriched AI security graph delivers real‑time visibility into how attacks propagate end‑to‑end, enabling security teams to pinpoint weak points and assess breach containment options system‑wide rather than in isolated workloads.
Network Posture analyses live network traffic and policy alignment against frameworks including NIST CSF, PCI DSS, and DORA, giving organisations a continuous measure of security maturity across connected environments.
“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 defence remains breach containment.”
The company’s latest research illustrates how agentic AI is changing adversary tactics—enabling autonomous intrusion attempts that move laterally at machine speed through enterprise infrastructure. The system‑level visibility offered by Network Posture is designed to expose such propagation paths before attackers exploit them, correlating network activity with application and business context to improve segmentation and containment decisions.
Commenting on the implications of AI‑driven attacks, Dr Chase Cunningham, known as DrZeroTrust, observed: “Organisations still treat Zero Trust like a shopping list — buy more stuff, feel better, hope it works. Agentic AI is going to punish that mindset."
He adds that 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.”
Amid a landscape where AI reshapes both offence and defence, Illumio’s additions aim to redefine breach containment from an endpoint exercise to a holistic, real‑time view of connected risk.
