One console. Any environment. The Illumio Platform identifies and contains threats across hybrid, multi-cloud environments, stopping attacks before they become disasters. It is powered by an AI security graph and built for Zero Trust. Illumio stops breaches from spreading by isolating workloads across cloud, data center, and endpoints. When attackers get in, lateral movement is contained instead of cascading into a full compromise. Detection alone is not enough — the gap between spotting a threat and stopping it is where breaches become disasters, and Illumio closes that gap with fast, automated containment. Core capabilities: - Illumio Segmentation — Microsegmentation that stops lateral movement across any environment. - Illumio Insights — AI cloud detection and response that surfaces threats and contains them in one click. - AI security graph — Maps every connection across your environment so that policy and detection share one source of truth. It is built for security and infrastructure teams responsible for reducing breach impact, operationalizing Zero Trust, and unifying protection across hybrid and multi-cloud environments. --- # Illumio Segmentation Source: https://www.illumio.com/illumio-segmentation Microsegmentation that stops lateral movement across data center, cloud, and endpoints. Illumio Segmentation contains breaches by controlling how workloads communicate. By mapping every connection and applying a least-privilege model to the flow of traffic, it stops ransomware and attackers from moving laterally across an environment — turning a potential disaster into a contained event. Illumio builds a real-time map of application and workload traffic, then lets teams write and enforce segmentation policy based on that visibility. Policy follows the workload across data center, cloud, and end-user devices, rather than being tied to network addresses, which dramatically reduces the architectural complexity of traditional network-based segmentation. Key benefits: - Visibility — See application and workload traffic across the environment to eliminate blind spots. - Containment — Stop lateral movement so a single compromised workload cannot spread. - Zero Trust enforcement — Apply least-privilege access east-west and north-south. - Reduced complexity — Decouple segmentation from the underlying network. Common use cases: ransomware and breach containment; protecting high-value applications and data; securing east-west (interior) and north-south (perimeter) traffic; operationalizing a Zero Trust architecture. --- # Illumio Insights Source: https://www.illumio.com/illumio-insights AI cloud detection and response (CDR) that identifies lateral movement, detects attacks, and contains threats in one click. Illumio Insights is a cloud detection and response solution built on an AI security graph. It identifies lateral movement risks, detects attacks, and contains threats instantly across hybrid, multi-cloud environments — helping security teams expose real threats, reduce false positives, and show impact with every investigation. Insights observes activity across your environment and uses the AI security graph to connect related signals into context-rich detections. Instead of a flood of disconnected alerts, teams see prioritized threats with the context needed to act, and can contain a compromised workload with a single action. Key benefits: - Detection at cloud scale — Identify lateral movement and attacks across hybrid, multi-cloud environments. - Context-rich analysis — Use the AI security graph to prioritize real threats and cut false positives. - One-click containment — Stop a threat the moment it is identified. - Deep observability — Maintain visibility into how workloads communicate. Insights includes an AI teammate, the Insights Agent, that helps prioritize and stop critical threats with context-rich analysis and deep observability. --- # Ransomware Containment Source: https://www.illumio.com/solutions/use-cases/ransomware Control lateral movement to stop ransomware attacks from becoming cyber disasters. Ransomware does its damage by spreading. Once an attacker gains a foothold, they move laterally to reach high-value systems and data. Illumio limits the blast radius of an attack by isolating workloads, so ransomware is contained at the point of entry instead of cascading across the environment. Traditional defenses focus on keeping attackers out. But breaches are inevitable, and once inside, ransomware moves laterally across flat networks at speed. Detection without fast containment leaves a gap that attackers exploit. How Illumio helps: - Visibility — Map workload and application traffic to see how an attack could spread. - Proactive segmentation — Apply least-privilege policy so only required connections are allowed. - Rapid containment — Isolate compromised workloads to stop lateral movement instantly. - Resilience — Recover and restore securely with Zero Trust Segmentation in place. The outcome: reduce the impact of an attack, protect critical applications and data, and maintain operations even when a breach occurs. --- # What is Zero Trust Segmentation? Source: https://www.illumio.com/cybersecurity-101/zero-trust-segmentation Zero Trust Segmentation (ZTS) applies the "never trust, always verify" principle to the connections between workloads, containing breaches by allowing only the traffic that is explicitly required. Zero Trust Segmentation is a modern approach to microsegmentation that supports a Zero Trust security strategy. Rather than assuming everything inside the network is safe, ZTS treats every connection as untrusted by default and permits only the communication that an application legitimately needs. Flat, overly permissive networks let attackers move laterally once they are inside. ZTS shrinks that freedom of movement, so a single compromised workload cannot become a full-scale breach. It is foundational to achieving Zero Trust and to containing ransomware and other fast-moving attacks. How it works: - Visibility — Build a real-time map of how workloads and applications communicate. - Least-privilege policy — Allow only the connections that are required; deny the rest. - Enforcement that follows the workload — Policy is tied to the workload, not the network, so it holds across data center, cloud, and endpoints. - Containment — When a breach occurs, lateral movement is already restricted. Traditional, network-based segmentation depends on firewalls, VLANs, and IP addresses, which become complex and brittle at scale. ZTS decouples policy from the network, reducing architectural complexity while improving containment.
