Your AI writes code fast. Who checks if it's secure?
Cursor, Copilot, and ChatGPT ship code in seconds — but 80% of AI-written code has security issues. Shieldy catches them before you deploy.
How It Works
Three steps to secure your codebase
Connect GitHub
Link your repo in one click. Works with your existing workflow.
Shieldy Scans Your Code
Our advanced scanner checks every line for security issues, bad patterns, and risky dependencies.
Fix with One Click
Get plain-English explanations and one-click fixes. No security expertise needed.
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, and many more
const query = `SELECT * FROM users
WHERE email = '${email}'`
const secret = "sk_live_a1b2c3"
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
$ shieldy simulate --target ./src

One score that tells you: safe to ship?
Get a clear 0–100 security score for every repo. Set a minimum score to block unsafe deploys automatically.
- Instant score after every scan
- Block deploys that aren't safe enough
- Track your score over time
- Share reports with your team
Your packages could be the weak link
Every package install adds someone else's code to your project. Shieldy watches for known security bugs in all your dependencies.
- Alerts you to known security bugs
- Checks license compatibility
- Detects compromised packages
- Suggests safe update paths

Don't just take our word for it
See why thousands of developers trust Shieldy to secure their code
“Shieldy caught a critical SQL injection that Cursor generated in my auth flow. Would have been a disaster in production.”
Alex Chen
Full-Stack Developer @ Vellum
“We integrated Shieldy into our CI pipeline. Our security score went from 47 to 93 in three weeks. The team barely had to change their workflow.”
Priya Sharma
CTO @ Stackbyte
“I ship solo with Cursor and Claude. Shieldy is like having a security engineer on call 24/7. Found 12 hardcoded secrets I totally missed.”
Marcus Rivera
Indie Hacker
“The dependency scanner alone justified the cost. It flagged a compromised npm package before it made it to staging.”
Sarah Kim
Engineering Lead @ Patchwork
“Clients now ask how I guarantee code security. I just show them the Shieldy report. Instant credibility boost.”

“Most SAST tools drown you in false positives. Shieldy's AI actually understands context — we cut our triage time by 80%.”
Emily Zhang
Security Engineer @ Nimbly
“We were about to deploy with a wide-open admin endpoint. Shieldy blocked the merge. That alone paid for a year of the tool.”
Daniel Park
Co-founder @ Launchfast
“Set it up in under 5 minutes. Scans run on every PR now. The team forgot it was even there — until it caught something critical.”
Rachel Torres
DevOps Lead @ Gridline
“Switched from Snyk for the AI code analysis. Shieldy finds logic-level vulnerabilities that pattern matchers completely miss.”
Liam O'Brien
Senior Developer
“The plain-English explanations are a game-changer. Junior devs on my team fix security issues without escalating now.”
