Alternatives to 42Crunch for Framework migration validation

When migrating between API frameworks or runtime environments, verifying that security behaviors remain consistent is essential. This tool is designed to support that validation by comparing runtime responses against expected security characteristics defined in your API specification. It focuses on configuration issues and detectable deviations rather than attempting to certify or guarantee framework compliance.

Findings from each scan map directly to three frameworks: PCI-DSS 4.0, SOC 2 Type II, and OWASP API Top 10 (2023). For all other frameworks, the tool aligns with security controls described in the target standard and supports audit evidence collection. It does not claim certified status, nor does it ensure or guarantee compliance with any regulation.

During a framework migration, you need to know whether authentication expectations, object-level constraints, and data exposure risks change. The scanner covers 12 categories aligned to OWASP API Top 10, including authentication bypass, broken object level authorization (BOLA), broken function level authorization (BFLA), property authorization, input validation, rate limiting, data exposure, encryption, SSRF, inventory management, unsafe consumption, and LLM/AI security. OpenAPI 3.0, 3.1, and Swagger 2.0 specs are parsed with recursive $ref resolution, and findings are cross-referenced against the spec to highlight undefined security schemes, sensitive fields, deprecated operations, and missing pagination.

Authenticated scans are available starting at the Starter tier and support Bearer, API key, Basic auth, and Cookie credentials. Domain verification is enforced through DNS TXT records or an HTTP well-known file so only the domain owner can scan with credentials. The scanner sends read-only methods (GET and HEAD) plus text-only POST for LLM probes, with destructive payloads never sent. Private IPs, localhost, and cloud metadata endpoints are blocked at multiple layers, and customer data can be deleted on demand and is never used for model training.

Each scan produces a risk score from A to F and a prioritized list of findings with remediation guidance. You can review scans in a web dashboard, track score trends, download branded compliance PDFs, and integrate via CLI, GitHub Action, MCP Server, or a native API client. Continuous monitoring options include scheduled rescans, diff detection, email alerts, HMAC-SHA256 signed webhooks, and Slack or Teams notifications. This tool does not fix, patch, block, or remediate issues, does not perform active SQL injection or command injection testing, does not detect business logic vulnerabilities, does not detect blind SSRF, and does not replace a human pentester for high-stakes audits.
