42Crunch vs Salt Security: which is better?

Both tools focus on API security, but their testing approaches differ significantly. middleBrick is a black-box scanner that submits read-only methods (GET and HEAD) plus text-only POST for LLM probes. It does not modify, delete, or write any data. The scan completes in under a minute and covers 12 categories aligned to OWASP API Top 10 (2023), including authentication bypass, IDOR, input validation, data exposure, and LLM security probes. It parses OpenAPI 3.0, 3.1, and Swagger 2.0 with recursive $ref resolution and cross-references spec definitions against runtime findings.

42Crunch takes a more production-centric compliance and policy enforcement approach. It emphasizes runtime protection, API gateways, and policy-as-code, with a strong focus on traffic inspection and enforcement in live environments. While it can validate configurations and schemas, its testing is less oriented around standardized adversarial profiles and more around enforcing organizational rules and regulatory expectations at scale.

middleBrick maps findings directly to PCI-DSS 4.0, SOC 2 Type II, and OWASP API Top 10 (2023). It detects exposed PII such as email and context-aware SSN, API key formats (AWS, Stripe, GitHub, Slack), and authentication misconfigurations like JWT alg=none, expired tokens, or missing claims. It flags dangerous HTTP methods, CORS wildcard usage, sensitive header leakage, and SSRF indicators such as internal IP references in URL-accepting parameters.

42Crunch aligns strongly with regulatory frameworks, helping teams prepare for audits around SOC 2 and PCI-DSS through policy enforcement and traffic monitoring. It provides detailed insights into request patterns and gateway-level anomalies, but it does not expose the same breadth of proactive adversarial testing that middleBrick offers through its OWASP-aligned scan profiles. For teams whose primary need is demonstrating control enforcement at the gateway, 42Crunch can be a fit, whereas teams focused on discovery and guided remediation may find middleBrick more actionable.

middleBrick supports authenticated scans at the Starter tier and above, including Bearer, API key, Basic auth, and Cookie-based authentication. A domain verification gate is required, using DNS TXT records or an HTTP well-known file to ensure only the domain owner can scan with credentials. The scanner forwards a strict header allowlist limited to Authorization, X-API-Key, Cookie, and X-Custom-* headers.

42Crunch relies heavily on its positioned gateway or sidecar proxies for context about authenticated sessions and policies. It does not require a separate domain verification step for scans, but it expects traffic to pass through its enforcement layer to build meaningful profiles. If your architecture already forces all API traffic through a gateway with existing identity context, 42Crunch can leverage that, but you lose the portable, gateway-agnostic nature of a black-box scanner like middleBrick.

middleBrick offers a CLI via an npm package, a web dashboard for reports and trend tracking, a GitHub Action to gate CI/CD builds, an MCP server for AI coding assistants, and a programmatic API for custom integrations. Its Pro tier adds scheduled rescans, diff detection across scans, email alerts, HMAC-SHA256 signed webhooks, and compliance report downloads. The tool is designed for lightweight deployment without requiring agents or SDKs in the target environment.

42Crunch integrates tightly with API gateways and service meshes, providing policy templates and analytics within those platforms. It focuses on continuous monitoring and real-time enforcement rather than periodic scanning. Teams that already operate a gateway-centric security model and want to codify policies as code may prefer this approach, while teams seeking a portable scanner that runs anywhere without gateway dependency are better served by middleBrick.

For most security and engineering teams that need an objective, on-demand assessment of API risk without requiring access to source code or infrastructure, middleBrick is the better choice. It delivers clear, prioritized findings mapped to recognized standards, fast scans, and flexible deployment options. It is especially suitable for teams performing pre-release checks, third-party API vetting, or periodic posture reviews.

42Crunch is a stronger fit for organizations that enforce security policy at the gateway level and want continuous, automated enforcement rather than point-in-time scanning. If your workflow depends on runtime protection and traffic inspection within a controlled environment, and you already have identity context flowing through proxies, 42Crunch can complement existing controls. In an apples-to-apples comparison of scanning capabilities and breadth of testing, middleBrick holds the advantage for teams focused on discovery, measurement, and remediation guidance.
