Illumio · Zero Trust Breach Containment
Best Zero Trust Security Platform
Overview
Illumio, the breach containment company, helps organizations apply Zero Trust inside their environments—where today's most damaging attacks occur. In hybrid and multi‑cloud estates, breaches are inevitable. The greatest harm happens when attackers move laterally through over‑trusted internal connections to reach critical systems.
Illumio is built for that moment. Our approach focuses on containing the breach, reducing blast radius, and keeping operations running during an incident—rather than relying solely on prevention.
The Illumio Platform delivers continuous visibility and enforcement to enable breach containment at scale. Illumio Insights provides real‑time visibility into internal traffic and abnormal behavior, while Illumio Segmentation enforces policy‑based controls to isolate compromised workloads and block unauthorized communications without network disruption.
Together, these capabilities enable security teams to move quickly from visibility to action—stopping lateral movement before it causes operational impact.
Illumio is recognized as a Leader in the Forrester Wave™: Microsegmentation Solutions (Q3 2024), positioning segmentation as a core pillar of Zero Trust by enforcing least‑privilege access and removing implicit trust across hybrid environments.
Key Capabilities
- Segmentation grounded in Zero Trust principles: Uses segmentation to stop lateral movement by enforcing least‑privilege communication between workloads and applications, removing implicit trust after initial access.
- Breach containment designed for survivability: Limits the spread of attacks when prevention fails, keeping incidents manageable and accelerating recovery.
- Continuous internal visibility tied directly to action: Provides real‑time visibility into traffic and dependencies and translates insight into enforceable segmentation policies.
- Policy‑based isolation without network redesign: Isolates compromised workloads and reduces blast radius without requiring network changes or disrupting operations.
- Consistent protection across hybrid and multi‑cloud environments: Applies segmentation seamlessly across data centers, clouds, and endpoints where organizations operate today.
- Board‑ready reporting with clear security outcomes: Demonstrates reduced lateral movement risk, smaller blast radius, and improved operational resilience.
How we are different
Illumio operationalizes Zero Trust at the moment that matters most: after initial access. Many Zero Trust approaches stop at access decisions. Illumio prevents attackers from turning an initial foothold into a widespread incident by containing lateral movement inside over‑trusted internal environments.
Illumio combines continuous visibility with enforcement in a single platform. Instead of "see and alert," security teams can see and act. Insight into internal traffic maps directly to segmentation policy, enabling control without waiting on network redesign.
Illumio treats Zero Trust as a resilience strategy. The goal is not to promise perfect prevention, but to ensure breaches do not become disasters.
