SYSDIG
Sysdig is the first unified approach to monitor and secure containers across the entire software lifecycle and helps you gain trust in your container-based microservices platform. Sysdig gives you control over and accelerates the transition to cloud native technologies by giving insights into day-to-day telemetry and security operations.
Sysdig is an Open Core company, meaning their core tools are open source, and offer commercial versions with enterprise features and support. For Sysdig, this means the sysdig, inspect and falco tools are their open core, and rely on a number of other existing open source tools, such as Prometheus. They build a number of commercially available products on top.
