The challenge

The danger of flat networks.

Traditional security focuses on the perimeter. But once an attacker or ransomware breaches it — through phishing, a stolen credential or an unpatched vulnerability — they move freely across your flat network, traversing from a user endpoint to a database server, infecting systems and exfiltrating data.

Segmenting with legacy firewalls or VLANs is complex, expensive and risks breaking critical application dependencies. You need a modern approach that stops the spread without halting the business.

The solution

Illumio Zero Trust Segmentation.

Decoupled from the network, Illumio uses the native stateful firewalls already in your workloads to enforce granular micro-segmentation across bare-metal, virtualized, containerized and cloud environments.

Real-time dependency mapping

An interactive, live map of all traffic between workloads — see how apps communicate before you write a single rule.

Automated containment

Pre-built policies instantly block commonly exploited ports (RDP, SSH, SMB) across the estate to shrink the attack surface.

Infrastructure-agnostic

Enforce consistent policy across data centres, private cloud and AWS, Azure and GCP — no network redesign.

Zero Trust ring-fencing

Isolate critical assets — payment databases, HR systems — so only authorized, authenticated systems can reach them.

Test mode before enforce

Simulate rules against live traffic without blocking connections — guaranteeing zero downtime at enforcement.

SIEM & PAM integration

Feed telemetry and alerts into your SIEM, monitoring and privileged-access tooling for unified visibility.

Core use cases

From problem to contained — in practice.

The need

Proactive ransomware containment

Prevent a single compromised server or endpoint from taking down the entire organisation.

The solution
  • A "kill switch" for lateral movement
  • Ransomware isolated to its point of entry
  • The rest of the data centre stays protected
The need

IT and OT environmental separation

Secure operational technology and legacy systems from broader IT risk without complex physical firewalls.

The solution
  • Logically separate IT and OT environments
  • An IT infection can't bridge into OT
  • Protect industrial & public-sector operations
The need

Secure cloud migration

Maintain consistent controls while migrating legacy applications from on-prem to the cloud.

The solution
  • Map dependencies and model policy first
  • Migrate workloads with segmentation intact
  • Centralized visibility wherever workloads run
The need

Protecting crown-jewel applications

Ensure only authorized systems can reach your most sensitive, high-value applications.

The solution
  • Ring-fence payment and HR systems
  • Allow only authenticated, authorized identities
  • Drastically reduce the blast radius of a breach

What reviewers say

Top-rated by the people who run it.

Independent voices from enterprise review platforms — verified practitioners deploying segmentation at scale.

"The real-time dependency map was a revelation — we finally saw every flow before writing policy. Ring-fencing our payment systems took days, not the months a firewall project would have."
