Intruder.io
Continuous external vulnerability scanner aimed at SMBs — published pricing from $113/mo per target group.
What it does well
- Clear, prioritized reporting helps small teams focus on the most critical vulnerabilities first.
- Integrates with CI/CD pipelines (e.g., GitHub Actions, GitLab) for automated developer workflows.
- User interface is clean and straightforward, requiring minimal security expertise to operate.
Where it falls short
- Primarily focused on external scanning; authenticated internal network scanning is less comprehensive.
- Pricing is per target group, which can become costly for organizations with many assets.
- No free tier is available for teams wanting to test the platform long-term.
