Alternatives to APIsec on Gin

middleBrick is a self-service API security scanner that operates as a black-box solution against Gin endpoints. You submit a target URL, and the service returns a risk score from A to F along with prioritized findings. The scanner uses only read-only methods (GET and HEAD) plus text-only POST for LLM probes, so it does not require access to your source code, SDKs, or agent installations. Scan completion typically occurs in under a minute, and the approach is compatible with any language, framework, or cloud environment.

The scanner evaluates 12 security categories aligned to the OWASP API Top 10 (2023). For Gin services, relevant detections include authentication bypass attempts, JWT misconfigurations such as alg=none or weak algorithms, security header validation, and WWW-Authenticate compliance. It also probes for Broken Object Level Authorization (BOLA/IDOR) via sequential ID enumeration and adjacent ID testing, as well as Broken Function Level Authorization (BFLA) through admin endpoint discovery and privilege leakage indicators. Other categories cover input validation (CORS wildcard usage and dangerous HTTP methods), data exposure risks (PII patterns and API key formats), and SSRF indicators involving URL-accepting parameters.

middleBrick parses OpenAPI 3.0, 3.1, and Swagger 2.0 specifications for Gin-based APIs, resolving recursive $ref entries to compare the spec against runtime behavior. Findings highlight undefined security schemes, sensitive field exposure, deprecated operations, and missing pagination definitions. For authenticated scanning, the tool supports Bearer tokens, API keys, Basic auth, and cookies. Domain verification is enforced through DNS TXT records or HTTP well-known files so that only domain owners can submit credentials, and forwarded headers are limited to Authorization, X-API-Key, Cookie, and X-Custom-* headers.

With Pro tier capabilities, middleBrick provides scheduled rescans at intervals of six hours, daily, weekly, or monthly. It detects diffs between scans, highlighting new findings, resolved items, and score drift. Alerting includes rate-limited email notifications and HMAC-SHA256 signed webhooks that auto-disable after five consecutive failures. The tool integrates into CI/CD via a GitHub Action that can fail builds when scores drop below a defined threshold, and an MCP server enables scanning from AI coding assistants. An API client supports custom integrations for programmatic workflows.

middleBrick is a scanning tool and does not fix, patch, block, or remediate issues. It does not perform active SQL injection or command injection testing, nor does it detect business logic vulnerabilities that require domain context. The platform surfaces findings relevant to compliance activities and helps you prepare for controls defined in PCI-DSS 4.0, SOC 2 Type II, and OWASP API Top 10 (2023). For other frameworks, it aligns with security controls described in applicable guidance but does not certify or guarantee compliance with HIPAA, GDPR, ISO 27001, NIST, CCPA, or similar regulations.
