What are the best AI tools for security code review?
Prefer tools that reason about data flow — where untrusted input enters and what it reaches — over pattern matchers. The vulnerabilities that matter in agent-written code are authorization gaps and injection, not known-CVE dependencies.

What to look for
- 01Does it trace untrusted input to a sink, or grep for risky function names? Only the first finds real injection paths.
- 02Does it check authorization, not just authentication? Row-level access control is where generated code most often fails.
- 03Does it validate the fix? A remediation nobody re-tested is a finding you closed, not a vulnerability you removed.
Common questions
- Is AI security review enough on its own?
- No. Treat it as a fast first pass that catches common classes early and cheaply. Anything handling money, credentials, or personal data still warrants a human audit before it ships.
- What do these tools miss most often?
- Business-logic flaws and broken authorization — cases where every line is individually correct but the combination lets one user reach another user's data. Those need someone who knows the intended rules.
