About DeployPass

DeployPass scans a public website for common deployment risks before you ship. It runs 19 passive checks covering security headers, CORS configuration, cookie flags, mixed content, and frontend exposure, then returns a pass or fail score with a shareable report. There is no login, port scanning, or exploitation involved, only observation of publicly visible responses. The whole product is free with no signup, and the vendor labels it free while the product is in beta. It is explicitly not a penetration test, so a pass does not prove an application is secure.

The free plan in practice

What you can actually do on DeployPass's free plan (No account needed, unlimited passive scans), where it stops, and when it's worth paying.

What you can do free

19 passive security checks per scan
Security headers, CORS, cookie flags, and mixed content checks
Shareable scan reports
No signup or account required

Where it stops

Passive checks only, not a penetration test
Cannot verify application security comprehensively
Vendor notes paid monitoring and deeper scans may come later

When to upgrade to a paid plan

Stay on the free plan while you're comfortably under the free plan's limit (No account needed, unlimited passive scans). It's worth moving to a paid plan once you consistently bump into that ceiling, need to remove branding, or want features the free tier holds back.
