42Crunch vs Noname Security

42Crunch positions itself as an API security gateway, placing enforcement near the ingress layer. It assumes you want request-time blocking and policy enforcement. Noname Security also offers scanning but emphasizes runtime protection and a gateway component. middleBrick targets engineers and security teams who need a fast, gateway-free assessment without adding infrastructure. Its black-box scanner requires only a URL, avoiding agent installation, SDK changes, or cloud-specific dependencies.

42Crunch provides API security as a service with a rules engine focused on gateway-level policy and threat prevention. Noname Security covers OWASP API Top 10 and includes runtime monitoring alongside scanning. middleBrick aligns its findings to OWASP API Top 10 (2023), PCI-DSS 4.0, and SOC 2 Type II by mapping detected issues to those frameworks. It performs black-box discovery across 12 categories, including authentication bypass, IDOR, privilege escalation, input validation, data exposure, SSRF, and LLM/AI security probes, with no intrusive payloads such as active SQL injection or command injection.

middleBrick operates as a read-only scanner, sending only GET and HEAD requests and text-only POST for LLM probes, with destructive payloads never sent. Private IPs, localhost, and cloud metadata endpoints are blocked at multiple layers. It parses OpenAPI 3.0, 3.1, and Swagger 2.0 with recursive $ref resolution, cross-referencing spec definitions against runtime behavior. The tool does not fix, patch, or block findings; it reports with remediation guidance. It does not perform active SQL injection or command injection, does not detect business logic vulnerabilities, and does not replace a human pentester for high-stakes audits.

Authenticated scanning in middleBrick supports Bearer, API key, Basic auth, and cookies, gated by domain verification via DNS TXT or HTTP well-known file. Only a limited set of headers is forwarded. Integrations include a Web Dashboard for trend tracking and compliance PDFs, a CLI with JSON or text output, a GitHub Action that can fail builds on score drops, an MCP server for AI coding assistants, and a programmatic API. Pro tier adds continuous monitoring with diff detection, scheduled rescans, email alerts, HMAC-SHA256 signed webhooks, and compliance report exports. Pricing ranges from a free tier with limited scans to paid tiers with increasing API coverage and team features.

Choose 42Crunch if you need API gateway enforcement and rules-based blocking as part of your runtime posture. Choose Noname Security if you want integrated runtime protection and monitoring alongside scanning. Choose middleBrick if you want a quick, gateway-free, black-box assessment that maps to compliance frameworks without code access or infrastructure changes. Consider your team’s need for authenticated scans, the importance of open-dashboard reporting, and whether continuous monitoring fits your budget. Balance the depth of runtime features against the overhead of deployment and maintenance when comparing these tools.
