Top 50 Security Scanning Tools — May 2026

Security scanning buyers are comparing tools that cover very different parts of the stack: cloud posture, Kubernetes, API security, secrets, containers, AI-agent controls, vulnerability management, and CI/CD checks. The ToolVitals dataset for May 2026 scores 50 Security Scanning Tools using the supplied health, shipping, GitHub star, status, and ToolVitals score fields.

The ranking is ordered by ToolVitals score from highest to lowest, with GitHub stars used only as a secondary popularity signal when scores are tied. That is why several tools with a 94 ToolVitals score lead the list, and NetBird ranks ahead of other 94-score tools because it has the largest GitHub star count among that tied group.

Akto ranks third with a 94 ToolVitals score, 97 health score, 100 shipping score, and 1,471 GitHub stars. Its description focuses on API discovery, posture, and CI/CD testing, which makes it one of the more directly API-security-oriented tools near the top of the ranking.
