Migrating from 42Crunch to middleBrick for NIS2 directive readiness

Many teams use 42Crunch to enforce gateway policies and surface common API issues. Its deployment model relies on a managed cloud control plane and injected proxies, which introduces dependency on the vendor for policy updates and runtime behavior. When assessing NIS2 directive readiness, you need to map existing detections and response playbooks to specific technical controls, and understand what evidence you can retain and reproduce independently.

middleBrick is a self-service API security scanner that operates as a black-box tool: no agents, no SDKs, and no code access are required. You submit a URL and receive a risk score from A to F with prioritized findings. Scans complete in under a minute using read-only methods plus text-only POST for LLM probes. This approach supports any language, framework, or cloud target, which reduces operational coupling and aligns with NIS2 emphasis on asset inventory and independent verification.

The scanner evaluates 12 categories aligned to OWASP API Top 10 (2023), including authentication bypass, BOLA and BFLA, property authorization, input validation, rate limiting, data exposure, encryption, SSRF, inventory management, unsafe consumption, and LLM/AI security. Findings map directly to OWASP API Top 10 (2023) and support controls described in SOC 2 Type II and PCI-DSS 4.0. For other frameworks, the tool helps you prepare for and aligns with security controls described in relevant standards, while providing audit evidence through exportable reports.

With Starter tier and above, you can enable authenticated scanning using Bearer tokens, API keys, Basic auth, and cookies. Domain verification is enforced through DNS TXT records or an HTTP well-known file, ensuring that only the domain owner can scan with credentials. The scanner forwards a restricted allowlist of headers, and all scan data is deletable on demand, supporting evidence retention and data minimization requirements under NIS2.

Pro tier adds scheduled rescans every 6 hours, daily, weekly, or monthly, with diff detection to highlight new findings, resolved findings, and score drift. Email alerts are rate-limited to one per hour per API, and HMAC-SHA256 signed webhooks can notify monitoring systems, with auto-disable after five consecutive failures. The CLI and GitHub Action allow CI/CD gating, so risk thresholds can be integrated into your NIS2 compliance workflows. Note that the tool detects and reports with remediation guidance, but does not fix, patch, block, or remediate issues.
