AI's Security Limitations in Code Review

AI won't catch your security vulnerabilities. But it might save you hundreds of hours fixing them. Joseph Katsioloudes recently demonstrated something revealing at AI Native DevCon: he asked GitHub Copilot to find security issues in code. It correctly identified SQL injection. It also flagged passwords stored in plain text, except they weren't actually there. Pure hallucination. 𝗧𝗵𝗲 𝗿𝗲𝗮𝗹 𝗽𝗿𝗼𝗯𝗹𝗲𝗺? Run the same prompt twice, get different results. Same code, same model, completely different outputs. Here's what actually works: • Purpose-built security tools handle detection (they're deterministic and reliable) • AI handles fixing (where it genuinely excels) • This hybrid approach helps teams fix vulnerabilities 3x faster Joseph's team built something practical for this: instruction files that prompt AI to perform structured security assessments of dependencies. Most developers spend under 15 minutes evaluating a new package before adopting it. These prompts deliver executive summaries with flagged risks and verifiable sources. The takeaway isn’t that AI is ineffective for security. It’s that understanding where AI is strong versus where it can be unreliable makes all the difference.
