description Illumio Core Overview

Illumio Core is a policy-based firewall solution that analyzes network traffic in real-time to enforce security rules based on application conversations rather than traditional IP addresses or ports, providing granular control and reducing the attack surface.

help Illumio Core FAQ

What problem does Illumio Core solve that a normal firewall may miss?

Illumio Core is built for microsegmentation, so it can control workload-to-workload communication inside a data center or cloud environment. That helps limit lateral movement after an attacker reaches one system, where a perimeter firewall may have little visibility.

How does Illumio Core write rules around applications?

It uses application relationships, workload labels, and observed conversations to express policy instead of relying only on changing IP addresses and ports. That lets a team say which application tiers may talk, then block connections outside that design.

Does Illumio Core replace an EDR tool?

No, Illumio Core enforces network segmentation, while an EDR product such as Carbon Black Cloud watches endpoint behavior and investigates processes. Many security teams use both because blocking lateral traffic and detecting a malicious process are separate controls.

Can Illumio Core protect hybrid cloud workloads?

Its policy model is intended for workloads across data centers and cloud environments, not only a single flat office network. Confirm support for the exact operating system, cloud account, and deployment method before treating every asset as covered.
