middleBrick vs APIsec

middleBrick is a black-box API security scanner that submits requests to a reachable endpoint and analyzes responses. It does not require agents, SDKs, or access to source code, and supports any language or framework. Scans use read-only methods (GET and HEAD) plus text-only POST for LLM probes, complete in under a minute, and map findings to OWASP API Top 10 (2023).

APIsec focuses on application security testing with a mix of passive analysis and active testing. Its public documentation describes dynamic scans that attempt to evaluate runtime behavior, plus options for authenticated testing where credentials are provided. The tool aims to cover OWASP API Top 10 and related standards, though its exact test catalog is defined by the vendor.

middleBrick detects 12 categories aligned to OWASP API Top 10 (2023), including authentication bypass, JWT misconfigurations, BOLA and IDOR, privilege escalation, over-exposed properties, input validation issues, rate limiting behavior, data exposure patterns such as PII and API keys, encryption misconfigurations, SSRF indicators, inventory issues, and LLM/AI security probes. Findings map directly to OWASP API Top 10 (2023) and supports audit evidence for SOC 2 Type II and PCI-DSS 4.0.

APIsec reports detections aligned to common frameworks, including references used for SOC 2 Type II and PCI-DSS 4.0. For other regulatory frameworks, APIsec materials describe alignment with security controls described in HIPAA, GDPR, ISO 27001, NIST, CCPA, and related standards using alignment-based language. middleBrick does not claim certification or compliance guarantees for any framework.

middleBrick supports authenticated scans at the Starter tier and above, handling Bearer tokens, API keys, Basic auth, and cookies. Domain verification is required, allowing only the domain owner to scan with credentials. A strict header allowlist is applied, forwarding only Authorization, X-API-Key, Cookie, and X-Custom-* headers.

APIsec provides authenticated scan options when credentials are supplied, with documented guidance on configuring authentication methods. Public information notes that APIsec validates authentication setups and can test endpoints behind login flows, though specific header allowlisting policies are defined by the user during configuration.

middleBrick offers a web dashboard for scan management and trend tracking, downloadable compliance PDFs, a CLI via an npm package, a GitHub Action for CI/CD gating, an MCP server for AI coding assistants, and a programmatic API for custom integrations. Pro tier adds scheduled rescans, diff detection, email alerts, signed webhooks, and Slack or Teams notifications.

APIsec provides integrations through agents, CLI tools, and CI/CD plugins, with documented steps to incorporate scans into development workflows. Public tier offerings include dashboard access and scheduled scans, with enterprise options for extended API coverage and team collaboration features.

middleBrick is read-only and does not fix, patch, block, or remediate. It does not perform active SQL injection or command injection testing, does not detect business logic vulnerabilities, and does not perform blind SSRF testing. Private IPs, localhost, and cloud metadata endpoints are blocked at multiple layers, and customer data can be deleted on demand and is never sold or used for model training.

APIsec relies on its scanning engine to detect a broad set of runtime issues while avoiding intrusive exploit tests. The tool documents that certain vulnerability classes, such as business logic flaws, require manual review, and that scans should complement but not replace comprehensive manual assessments.
