Snyk VulnBench JS 1.0: Can LLMs Find the Same Bugs Twice?

Snyk's 300-run benchmark reveals LLM security scanners produce inconsistent findings across runs, while catching different bug classes than traditional SAST — raising questions about pipeline trust.

Snyk VulnBench JS 1.0: 300 repeated scans show LLM security findings vary by run, while SAST and models catch different vulnerability gaps.

Editorial Analysis

Why it matters

As enterprises integrate AI-powered scanning into CI/CD, non-deterministic results risk both missed vulnerabilities and alert fatigue — demanding hybrid strategies.

What to do

Pair LLM-based scanners with deterministic SAST tools and track finding consistency metrics before relying on AI-only gating in release pipelines.

Board brief

AI code scanners show promise but lack consistency — hybrid approaches with traditional tools remain essential for reliable vulnerability gating.
