● illumio · Zero Trust Segmentation

Contain the breach before it spreads.

Attackers don't stop at the perimeter — they move laterally. Illumio's AI-powered breach containment platform sees every connection, contains attacks in real time, and stops one compromised workload from becoming an enterprise-wide event.

The problem

The hybrid cloud network must be secured.

Identity, perimeter and app controls all matter — but once an attacker is inside, the network is where they travel. Flat, over-connected networks let a single foothold reach everything.

Lateral movement

One foothold. Unlimited reach.

From a single phishing click or unpatched VM, attackers pivot across servers, OT, endpoints and cloud workloads. The longer they move undetected, the closer they get to your crown jewels.

Implicit trust is the vulnerability.

Once inside, east-west traffic is rarely inspected or restricted.

Hybrid expands the blast radius.

Data center, public cloud and remote endpoints share one flat fate.

Prevention is fallible.

Detection works — stopping the spread is where most teams struggle.

East-west is the blind spot.

Legacy defenses watch north-south traffic entering and leaving — but most attacks travel east-west, between internal systems, where flows go uninspected.

Why Illumio

The control that absorbs failure.

Prevention will eventually be bypassed. Segmentation determines whether a breach is survivable — addressing the exact control gap that modern attacks make urgent.

1

Continuous real-time observability

You can't stop movement you can't see. Illumio gives live visibility into all communication paths and implicit trust relationships.

2

Inevitable compromise → contained incidents

Segmentation prevents one compromised workload from becoming an enterprise-wide event.

3

The control that absorbs failure

When prevention is fallible — and it will be — segmentation determines whether a breach is survivable.

4

Vulnerability-agnostic protection

Illumio limits lateral movement regardless of the exploit used. You don't need to know the CVE for the policy to hold.

Zero Trust Segmentation

One platform. Many high-value outcomes.

Visibility and segmentation feed a single Zero Trust Segmentation Platform — spanning cloud, data center and endpoints — so the same controls power dozens of security and compliance use cases.

Breach containment anchored in observability.

Complete coverage of lateral movement risk — proactively reducing exposure, and reactively containing what gets through.

The shift

From flat & exposed — to contained.

Microsegmentation turns one open network into thousands of isolated zones. A breach in one workload stays in one workload.

With segmentation

Contain the breach.

Least-privilege policy by application, environment and role draws a perimeter around every workload — across data center, public cloud and users. The attack hits a wall instead of an open plain.

Ring-fence crown jewels first.

Protect the assets that matter without redesigning the network.

Allow only what's needed.

Every other path is denied by default — lateral movement has nowhere to go.

Test before you enforce.

Model each rule against real traffic in draft mode, then switch enforcement on with confidence — no outages, no guesswork.

Coverage

Segment everywhere your workloads run.

From the mainframe to cloud-native — one consistent policy model across every platform in your estate, enforced by a lightweight VEN on hosts or fully agentless in the cloud. No workload is left unsegmented.

How it works

Real-time adaptive policy.

The Policy Compute Engine ingests resource & flow data and computes least-privilege rules; lightweight enforcement nodes apply them on every workload — and adapt the moment anything changes.

What Insights surfaces

Detection that reads the whole graph.

Risk is scored continuously across every flow and resource — so analysts triage the threats that matter first, then quarantine with one click.

Ransomware protection

Pinpoint exposed RDP & SMB paths and the workloads ransomware would use to spread.

Malicious IP threats

Flag inbound and outbound traffic to known-bad IPs, scored against live threat intel.

Risky services

Surface high-risk protocols — SSH, VNC, TeamViewer, RustDesk — and exactly where they're exposed.

Shadow LLMs

Detect unsanctioned AI and LLM traffic leaving your environment before data does.

External data transfer

Watch for unusual outbound volume that signals exfiltration in progress.

DORA & compliance

Map flows against DORA, PCI and regional scopes for audit-ready resilience reporting.

Container segmentation

Segmentation that follows every container.

Containers spin up in seconds — your security should too. Illumio segments containerized hosts alongside the rest of your environment, with one consistent label-based policy across Kubernetes and Red Hat OpenShift.

Why Illumio for containers

Speed of containers, without losing breach control.

Microservices expand the attack surface, and native cloud controls work in silos. Illumio segments both containerized and non-containerized apps under one policy model.

Centralized visibility.

See clusters and pod-to-pod traffic in one application dependency map — alongside VMs, on-prem and cloud.

No firewall rules to write.

Policy by label and business context, enforced close to the workload.

Adaptive & agile.

Policy adjusts as namespaces, pods and services change — no manual scripts, no CI/CD delays.

Dynamic Kubernetes discovery

Automatically find namespaces, pods and services as teams create them — no manual setup.

Automatic labeling & inheritance

Container workload profiles apply a default policy across clusters the instant a pod starts.

Pre-built OpenShift templates

Ready-made policies protect cluster nodes and core services, separate from the workloads on them.

DevSecOps

Build Zero Trust into the pipeline — without slowing delivery.

Define and test segmentation policy in plan, build and test; enforce and monitor in deploy. Illumio translates high-level policy into firewall rules automatically — no thousands of hand-written rules.

Closes the DevOps gap

Security that fits agile — and stops attacks in progress.

Tailored policy.

Segment by role, application, environment (dev / test / prod) and location.

No security PhD required.

High-level policy compiles to detailed rules automatically — devs stay devs.

Instant isolation.

See traffic in real time and immediately block infected systems from the network.
