Is 42Crunch good for Post-deploy verification?

Post-deploy verification confirms that an API behaves as expected once it is reachable in production or staging. The process requires a scanner that operates without disrupting traffic, that respects deployment safety constraints, and that provides clear, actionable findings rather than raw tool outputs. Tests must be read-only, runtime checks aligned to recognized security standards, and reporting must integrate with deployment workflows and ownership models.

middleBrick is a self-service API security scanner designed for runtime verification after deployment. You submit a target URL and receive a risk score from A to F with prioritized findings. The scanner is black-box, requiring no agents, SDKs, or code changes, and works across languages, frameworks, and cloud environments. Scan duration is under one minute, using read-only HTTP methods (GET and HEAD) plus text-only POST for LLM probes. This approach limits operational impact while still surfacing misconfigurations and security issues observable from external requests.

The scanner maps findings to OWASP API Top 10 (2023), PCI-DSS 4.0, and SOC 2 Type II controls, which supports audit evidence for common compliance expectations. Detection categories include authentication bypasses, JWT misconfigurations such as alg=none or expired tokens, authorization flaws like BOLA and BFLA, PII and sensitive data exposure, input validation issues including CORS misconfigurations and dangerous HTTP methods, rate limiting and resource consumption signals, encryption and cookie security, SSRF indicators, inventory and versioning issues, unsafe consumption surfaces, and LLM/AI security probes across multiple scan tiers. OpenAPI specifications in versions 3.0, 3.1, and Swagger 2.0 are parsed with recursive $ref resolution, and findings are cross-referenced against the spec to identify undefined security schemes or deprecated operations.

For environments that require authenticated checks, middleBrick supports Bearer tokens, API keys, Basic auth, and cookies in Starter tier and above. Domain verification is enforced through DNS TXT records or HTTP well-known files so that only the domain owner can submit credentials for scanning. A strict header allowlist ensures that only Authorization, X-API-Key, Cookie, and X-Custom-* headers are forwarded, reducing side effects during verification. These capabilities allow controlled, authenticated scans without exposing internal systems or modifying production state.

middleBrick provides multiple integration options for post-deploy workflows. The web dashboard centralizes scans, score trends, and downloadable compliance reports, while the CLI supports on-demand checks via middlebrick scan <url> with JSON or text output. A GitHub Action can gate CI/CD pipelines when scores drop below a threshold, and an MCP server enables scanning from AI-assisted coding tools. Continuous monitoring (Pro tier) offers scheduled rescans, diff detection for new or resolved findings, email alerts, HMAC-SHA256 signed webhooks, and deletable data stored with strict retention policies.

At the same time, the tool does not fix, patch, block, or remediate issues; it detects and reports with remediation guidance. It does not perform active SQL injection or command injection testing, does not detect business logic flaws that require domain context, and does not perform blind SSRF tests that rely on out-of-band infrastructure. It is not a replacement for a human pentester in high-stakes audits, and it does not certify or guarantee compliance with any regulation.
