Its open-source offering, Calico Open Source, is the most widely adopted container networking and security solution. Tigera’s solutions specify security and observability as code to ensure consistent enforcement of security policies, which enables DevOps, platform, and security teams to protect workloads, detect threats, achieve continuous compliance, and troubleshoot service issues in real time.

Powering more than 100M containers across 1.5M nodes in 166 countries, Calico software is supported across all major cloud providers and Kubernetes distributions, and is used by leading companies including AT&T, Discover, Merck, ServiceNow, HanseMerkur, RealPage, L3Harris, and Mindbody.
