Security scanner for AI-generated code

Your AI writes code fast. Who checks if it's secure?

Cursor, Copilot, and ChatGPT ship code in seconds — but 73% of AI-written code has security issues. Shieldy catches them before you deploy.

Cursor wrote your login page. It also wrote a SQL injection.

AI code generators don't think about security. They write code that works — not code that's safe. Hackers love that.

73% of AI-generated code contains at least one security vulnerability.
login.js — AI Generated
// AI-generated login handler
app.post('/login', (req, res) => {
  const { username, password } = req.body;

  // ⚠️ SQL Injection vulnerability
  const query = `SELECT * FROM users
    WHERE username = '${username}'
    AND password = '${password}'`;

  db.query(query, (err, results) => {
    if (results.length > 0) {
      res.json({ token: jwt.sign(results[0]) });
    }
  });
});

How It Works

Three steps to secure your codebase

Step 1

Connect GitHub

Link your repo in one click. Works with your existing workflow.

Step 2

AI Scans Your Code

Our AI checks every line for security issues, bad patterns, and risky dependencies.

Step 3

Fix with One Click

Get plain-English explanations and one-click fixes. No security expertise needed.

Code Scanning

Finds the bugs your AI missed

Shieldy reads your code like a security expert would — understanding what it does, not just matching patterns.

  • Catches SQL injection, XSS, and more
  • Finds hardcoded secrets and API keys
  • Spots broken login and auth flows
  • Works with JS, TS, Python, Go, Ruby
auth.js

const query = `SELECT * FROM users

WHERE email = '${email}'`

SQL Injection — user input in query

const secret = "sk_live_a1b2c3"

Hardcoded API key detected
Hacker Simulation

See your app the way a hacker would

On every push, Shieldy runs real attack simulations against your code — so you find the holes before anyone else does.

  • Simulates the 10 most common attacks
  • Tests login bypass and permission flaws
  • Shows exactly what an attacker could exploit
  • Runs automatically on every push
