ARMO Platform is the only cloud security platform that continuously minimizes cloud attack surface based on runtime insights, while actively detecting and responding to cyberattacks with real risk context. This runtime-powered, Kubernetes-driven, cloud security platform, empowers businesses to break the vicious cycle of endless back and forth between security and DevOps/Engineering teams and achieve real cloud security. ARMO Platform enables DevOps, security, and platform teams to eliminate the security noise in their clusters from thousands of irrelevant alerts and focus on the most important and exploitable threats. This is done thanks to an eBPF-based runtime sensor which records application behavior and related activities. The recorded baseline is then enriched with relevant context from Kubernetes events, CI/CD data, cloud data and containers’ data. The result is an Application Profile DNA (APDTM), which is the holistic baseline for applications’ normal behavior, configuration, and policies. ARMO Platform protects any type of cloud and Kubernetes deployments: managed, on-premises, and air-gapped.
