ImmuniWeb
DAST + dark-web monitoring + compliance reporting — free public tests, paid quote-based platform.
Free tier: free Community Edition tests (SSL, headers, mobile, dark web)
What it does well
- Offers several free, public-facing security tests for SSL, mobile, and dark web exposure.
- Combines application security testing (DAST) with compliance and dark web monitoring in one platform.
- Provides detailed reports with grades and remediation advice, even on the free tools.
Where it falls short
- Core platform pricing is not public; requires contacting sales for a custom quote.
- The free tests are public, potentially exposing scan results to anyone with the URL.
- No self-hosted deployment option is available; the platform is cloud-only.
