  • CI/CD integration via GitHub Action
  • Authenticated scanning with header allowlist

CI/CD security gate requirements

A CI/CD security gate must be fast, deterministic, and non-disruptive to release velocity. It should introduce minimal maintenance overhead and integrate cleanly into existing pipelines without requiring code changes or special runtime dependencies. Gate criteria need to be objective, repeatable, and tied to a clear risk model that teams can act upon.

How middleBrick fits as an alternative to 42Crunch

middleBrick provides a black-box API security scanner designed for CI/CD gates. You submit an API URL and receive a risk score from A to F with prioritized findings. The scan completes in under a minute using read-only methods and text-only POST probes, avoiding intrusive payloads that would disrupt services.

Mapping to compliance frameworks

middleBrick maps findings to OWASP API Top 10 (2023), supports controls required by PCI-DSS 4.0, and aligns with audit evidence for SOC 2 Type II. It surfaces findings relevant to regulations such as HIPAA, GDPR, ISO 27001, NIST, CCPA, and others, while avoiding guarantees of certification or compliance.

Authenticated scanning for CI/CD

With Starter tier and above, authenticated scans validate how APIs behave with credentials. Supported methods include Bearer tokens, API keys, Basic auth, and cookies. Domain verification ensures only the domain owner can run authenticated scans, and a strict header allowlist limits forwarded headers to Authorization, X-API-Key, Cookie, and X-Custom-*.

Developer experience and integrations

The CLI allows a one-command scan with JSON or text output, suitable for local debugging and scripting. The GitHub Action fails the build when the score drops below a chosen threshold, enforcing quality gates before merge. For AI-assisted workflows, the MCP Server enables scanning from tools such as Claude and Cursor, and the Web Dashboard provides trend tracking and compliance PDF exports.

Operational safety and data handling

middleBrick follows a read-only safety posture, never sending destructive payloads. Private IPs, localhost, and cloud metadata endpoints are blocked at multiple layers. Customer scan data is deletable on demand and purged within 30 days of cancellation, and it is never sold or used for model training.

Frequently Asked Questions

Does middleBrick perform active injection tests like SQL injection?
No. It does not perform active SQL injection or command injection, as those require intrusive payloads outside its scope.
Can it replace a human pentester for high-stakes audits?
No. It does not replace a human pentester, especially for high-stakes audits, as it does not detect business logic vulnerabilities.
How are new findings tracked across scans?
With Pro tier, continuous monitoring produces diffs across scans to show new findings, resolved findings, and score drift. Alerts are rate-limited to one per hour per API.
Is compliance certification provided?
No. The tool surfaces findings that help prepare evidence for frameworks such as PCI-DSS 4.0 and SOC 2 Type II, but it does not certify compliance.
What happens to scan data after cancellation?
Customer scan data is deletable on demand and purged within 30 days of cancellation. It is never sold and never used for model training.
