ARMO

ARMO is a cloud-native security vendor founded in 2019 and headquartered in Tel Aviv, Israel, best known as the creator and primary maintainer of Kubescape, an open-source Kubernetes security scanner that became a Cloud Native Computing Foundation (CNCF) sandbox project. Kubescape scans Kubernetes manifests, Helm charts, live clusters and worker nodes for misconfigurations and known vulnerabilities against frameworks including NSA-CISA hardening guidance and MITRE ATT&CK, and has amassed several million downloads and thousands of GitHub stars as one of the more widely adopted open-source Kubernetes security tools.

The company’s commercial offering, the ARMO Platform, extends Kubescape’s open-source scanning with cloud application detection and response (CADR), Kubernetes security posture management (KSPM), cloud security posture management (CSPM), and vulnerability management that incorporates runtime reachability analysis, i.e., prioritizing vulnerabilities that are actually exploitable in a running workload rather than flagging every CVE in an image. This open-core model, monetizing an enterprise layer on top of a widely used free tool, is ARMO’s primary go-to-market and adoption funnel.

ARMO has raised approximately $34.5 million in total funding, including a $30 million round led by Tiger Global with participation from Hyperwise Ventures, Pitango First and Peled Ventures, and counts customers including Verizon, Nokia, Dell and Broadcom. For CISOs and platform teams running Kubernetes at scale, ARMO’s open-source-led adoption path and reachability-based vulnerability prioritization address real alert-fatigue and misconfiguration problems; its challenge is standing out in an increasingly crowded cloud-native/CNAPP security market where several larger vendors offer overlapping Kubernetes security capabilities.
