APIsec vs Protect AI: which is better?

middleBrick is a black-box API security scanner that submits read-only methods (GET and HEAD) plus text-only POST for LLM probes, while Protect AI often relies on agent-based instrumentation or requires code integration to understand runtime behavior. Because middleBrick does not need agents or SDKs, it can scan any language, framework, or cloud target that exposes an HTTP endpoint. Protect AI may deliver deeper runtime insights in environments where its agent can safely install, but that same dependency limits coverage and adds integration overhead.

middleBrick maps findings to OWASP API Top 10 (2023), PCI-DSS 4.0, and SOC 2 Type II, and it covers 12 vulnerability categories including authentication bypass, BOLA, BFLA, property authorization, input validation, rate limiting, data exposure, encryption, SSRF, inventory management, unsafe consumption, and LLM/AI security across three scan tiers. Protect AI provides broad coverage, yet middleBrick specifically validates authentication misconfigurations such as JWT alg=none, HS256, expired claims, and sensitive data in claims, and it detects API key patterns for AWS, Stripe, GitHub, and Slack alongside PII like email and context-aware SSN. For standards not framed as certifications, middleBrick helps you prepare for compliance by surfacing findings relevant to audits without claiming guarantees.

middleBrick supports Bearer, API key, Basic auth, and Cookie authentication in the Starter tier and above, gated by a domain verification step using DNS TXT records or an HTTP well-known file to ensure only the domain owner can scan with credentials. Header forwarding is limited to Authorization, X-API-Key, Cookie, and X-Custom-* for safety. Protect AI may support more auth mechanisms in agent-based flows, but middleBrick’s explicit allowlist and read-only posture reduce risk of accidental impact. middleBrick does not perform active SQL injection or command injection testing, does not attempt to exploit business logic, and does not replace a human pentester for high-stakes audits.

The middleBrick CLI enables one-command scans via middlebrick scan <url>, outputting JSON or text for scripting, while the Web Dashboard centralizes reports, score trends, and branded compliance PDFs. CI/CD integration is available through a GitHub Action that fails builds when scores drop below a threshold, and the MCP Server lets AI coding assistants trigger scans directly. Continuous monitoring on Pro schedules rescans every 6 hours, daily, weekly, or monthly, provides diff detection for new and resolved findings, and includes rate-limited email alerts and HMAC-SHA256 signed webhooks. Protect AI often emphasizes agent-driven workflows; middleBrick favors lightweight, programmatic access and integrations that fit into existing pipelines without requiring persistent runtime agents.

middleBrick parses OpenAPI 3.0, 3.1, and Swagger 2.0 with recursive $ref resolution, cross-referencing spec definitions against runtime findings to highlight undefined security schemes, sensitive fields, deprecated operations, and missing pagination. Scan data is deletable on demand and purged within 30 days of cancellation, and customer data is never sold or used for model training. Protect AI may offer richer runtime tracing, but middleBrick’s spec-driven approach provides transparent mapping between design and observed behavior, supporting audit evidence for security reviews.
