Alternatives to APIsec on Fiber
What middleBrick covers
- Black-box scanning with no agents or code access
- Under-one-minute scan time with read-only methods
- 12 OWASP API Top 10 (2023) aligned detection categories
- OpenAPI 3.0/3.1 and Swagger 2.0 parsing with $ref resolution
- Authenticated scans with strict header allowlist
- Continuous monitoring with diff detection and signed webhooks
Black-box scanning for any backend stack
Because it is a black-box scanner, the tool interacts with your API solely through HTTP requests. It does not require access to source code, SDKs, or build pipelines, so it works with any language, framework, or cloud environment used by Fiber or other backends.
Scan time remains under a minute using read-only methods (GET and HEAD) plus text-only POST for LLM probes. The approach avoids any runtime instrumentation, making it compatible with legacy, monolithic, or microservice architectures without requiring redeployment.
Detection aligned to OWASP API Top 10 and common compliance mapping
The scanner evaluates 12 categories aligned to OWASP API Top 10 (2023), including Authentication bypass, BOLA and BFLA, Property Authorization, Input Validation, Rate Limiting, Data Exposure, Encryption, SSRF, Inventory Management, Unsafe Consumption, and LLM / AI Security. Each finding maps to relevant controls in OWASP API Top 10 (2023).
It also maps findings to PCI-DSS 4.0 and SOC 2 Type II where the detected control patterns correspond to requirements in those frameworks. For other regulations, the tool helps you prepare for and supports audit evidence collection, while clearly avoiding any compliance certification language.
OpenAPI analysis and authenticated scan options
The tool parses OpenAPI 3.0, 3.1, and Swagger 2.0 files with recursive $ref resolution, then cross-references spec definitions against runtime behavior to identify undefined security schemes, sensitive fields, deprecated operations, and missing pagination.
Authenticated scanning supports Bearer, API key, Basic auth, and Cookie credentials. Domain verification is enforced via DNS TXT record or an HTTP well-known file so only the domain owner can run credentialed scans. A strict header allowlist limits forwarded headers to Authorization, X-API-Key, Cookie, and X-Custom-*.
Continuous monitoring and developer-focused integrations
Pro tier enables scheduled rescans every 6 hours, daily, weekly, or monthly, with diff detection to surface new findings, resolved findings, and score drift. Alerts are rate-limited to one email per hour per API and include HMAC-SHA256 signed webhooks that auto-disable after 5 consecutive failures.
Integrations target developers and CI/CD workflows via a web dashboard for trend tracking and branded compliance PDFs, a CLI (middlebrick scan <url>) with JSON or text output, a GitHub Action that fails builds when scores drop below a threshold, and an MCP server for use with AI coding assistants. An API client allows custom integrations.
Safety posture and explicit limitations
The scanner uses read-only methods only and never sends destructive payloads. Private IPs, localhost, and cloud metadata endpoints are blocked at multiple layers. Customer data is deletable on demand and purged within 30 days of cancellation; it is never sold or used for model training.
The tool does not fix, patch, block, or remediate issues; it detects and reports with remediation guidance. It does not perform active SQL injection or command injection testing, does not detect business logic vulnerabilities, does not cover blind SSRF, and does not replace a human pentester for high-stakes audits. Results should be interpreted as part of a broader security program.
