Snyk by Snyk

Snyk was the first to really do DevSecOps - fast, actionable, developer focused CI/CD security scanning. They also were early to consolidate scanners into a single place - IaC, Code, SCA, and Container. There are many platforms with small improvements over them - better reachability, workflows, etc. - but they remain a strong player in the space for having scaled so meaningfully across enterprises.
