Your AI assistant writes vulnerable code. Who's checking its work?

AI assistants like GitHub Copilot generate code with SQL injection, hardcoded secrets, and known CVEs roughly 40% of the time. These aren't exotic attack vectors. They're the stuff that slips through every day because your AI sounds confident about every suggestion it makes.

Traditional scanners use regex patterns and catch the obvious stuff. But AI-generated vulnerabilities are subtler. They look like valid code because they are valid code. You need a scanner that thinks like the AI that wrote them.

That's CodeVigil. Triple-check scanning with regex, AST, and GitHub Copilot LLM verification, right in your editor.

auth.py (AI-generated)
14def login(username, password):
15 db = get_connection()
16 query = f"SELECT * FROM users
17 WHERE name='{username}'"
SQL Injection (CWE-89): User input directly interpolated into SQL query. Use parameterized queries.
18 result = db.execute(query)
19 return result.fetchone()

What's Under the Hood

AI-assisted triple-check scanning, secret detection, dependency CVE checks, and Copilot Chat integration. Built for the code your AI writes.

Code Pattern Scanning

100+ regex patterns across SQL injection, XSS, command injection, SSRF, path traversal, and more.

Secret Detection

Catches AWS keys, GitHub tokens, API keys, and private keys sitting in your source code.

Dependency CVE Matching

Checks package.json, requirements.txt, go.mod, Gemfile, and more against 130,000+ known CVEs.

Triple-Check Scanning

AI-generated code needs AI-assisted scanning. Three layers: regex, AST, and GitHub Copilot LLM verification. They catch what single-pass tools miss.

Your AI Checks Its Own Work

Copilot wrote the code, now it checks its own work. Type @codevigil in Copilot Chat to scan, explain, and fix vulnerabilities without leaving your editor.

10 Languages

JS/TS, Python, Java, C#, Go, PHP, Ruby, C/C++, and Kotlin. If you write in it, we probably scan it.

Why not just use Snyk / SonarLint / Semgrep?

They're great tools, but none of them were built for AI-generated code. CodeVigil uses AI to scan what AI writes: triple-check analysis with regex, AST, and LLM verification, plus Copilot Chat integration.
