APIsec vs Cloudflare API Shield

This comparison focuses on deployment model and who can operate the tool. Cloudflare API Shield is a managed service tied to Cloudflare infrastructure and requires routing traffic through their edge. middleBrick is a self-service scanner that runs as a read-only assessment against any reachable API surface without code, agents, or SDKs.

For teams that need a quick, no-code check against external endpoints, middleBrick offers CLI and dashboard access without changing DNS or traffic routing. Cloudflare API Shield suits organizations already on Cloudflare who want integrated protection and monitoring at the edge.

Cloudflare API Shield emphasizes runtime protection and monitoring for APIs behind Cloudflare, including rate limiting integration, bot management, and WAF signals. It focuses on enforcement capabilities rather than deep specification analysis.

middleBrick maps findings to OWASP API Top 10 (2023), PCI-DSS 4.0, and SOC 2 Type II, with a scan surface that covers authentication bypass, BOLA, BFLA, property authorization, input validation, data exposure, SSRF, and LLM security probes. It supports OpenAPI 3.0, 3.1, and Swagger 2.0 with recursive $ref resolution and cross-references spec definitions against runtime behavior.

Unlike runtime enforcement, middleBrick does not fix, patch, block, or remediate. It reports findings with remediation guidance and detects issues such as debug endpoints, CORS misconfigurations, unsafe HTTP methods, and exposed API keys.

Authenticated scanning is available in middleBrick at Starter tier and above, supporting Bearer, API key, Basic auth, and Cookie methods. Domain verification is required so that only the domain owner can scan with credentials, and a strict header allowlist is applied.

middleBrick uses 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. Cloudflare API Shield operates within Cloudflare edge rules, applying its own bot and rate-control logic to traffic it terminates.

Cloudflare API Shield pricing is bundled with Cloudflare plans and tied to edge features, generally available at higher tiers or add-on costs for advanced bot management and rate limiting.

middleBrick offers a free tier at zero cost with 3 scans per month and CLI access, a Starter plan at 99 US dollars per month for 15 APIs with dashboard and email alerts, a Pro plan at 499 US dollars per month for 100 APIs with continuous monitoring and CI/CD integration, and Enterprise with unlimited APIs, custom rules, SSO, and audit logs. Only middleBrick provides clear per-API add costs and published thresholds for email alerts and webhooks.

Cloudflare API Shield integrates through Cloudflare configuration, DNS, and edge rules, making it suitable for teams that want enforcement close to traffic. Changes are applied via Cloudflare dashboard or API with immediate effect.

middleBrick provides a CLI for on-demand scans, a web dashboard for tracking score trends and downloading compliance PDFs, a GitHub Action to gate CI/CD, an MCP server for AI coding assistants, and a programmatic API for custom integrations. Scheduled rescans, diff detection, and HMAC-SHA256 signed webhooks are available in Pro and above. middleBrick does not replace a human pentester for high-stakes audits and does not detect business logic vulnerabilities that require domain understanding.

Choose Cloudflare API Shield if you are already heavily using Cloudflare edge services and want integrated runtime protection, bot mitigation, and rate limiting with minimal operational overhead.

Choose middleBrick if you need an independent, black-box scanner that works across languages and clouds, supports specification-aware checks against OpenAPI definitions, provides detailed OWASP-aligned findings, and fits into existing CI/CD or dashboard workflows without routing traffic through a specific provider.

Consider running middleBrick periodically for deep API security assessments while relying on Cloudflare or another edge solution for enforcement, and use the comparison criteria of deployment model, detection coverage, authentication requirements, pricing clarity, and integration fit to finalize your selection.
