Alternatives to Bright Security at Mid-market companies

middleBrick is a black-box API security scanner that requires no agents, SDKs, or code access. You submit a URL and receive a risk score from A to F with prioritized findings. Scans complete in under a minute, using read-only methods (GET and HEAD) and text-only POST for LLM probes. This approach suits mid-market environments where quick insight without intrusive testing is preferred.

The scanner covers 12 categories aligned to the OWASP API Top 10 (2023). It maps findings to PCI-DSS 4.0, SOC 2 Type II, and OWASP API Top 10 (2023), and helps you prepare for security controls described in HIPAA, GDPR, ISO 27001, NIST, and related regulatory frameworks. Detection capabilities include:

• Authentication bypass and JWT misconfigurations such as alg=none, HS256 use, expired tokens, missing claims, and sensitive data in claims.
• BOLA and IDOR via sequential ID enumeration and active adjacent-ID probing.
• BFLA and privilege escalation through admin endpoint probing and role/permission field leakage.
• Property authorization issues including over-exposure, internal field leakage, and mass-assignment surface.
• Input validation checks for CORS wildcard usage (with and without credentials) and dangerous HTTP methods.
• Rate limiting and resource consumption analysis via rate-limit header detection and oversized responses.
• Data exposure detection for PII patterns, API key formats, and error/stack-trace leakage.
• Encryption checks including HTTPS redirect, HSTS, cookie flags, and mixed content.
• SSRF probes targeting URL-accepting parameters and internal IP detection.
• Inventory issues such as missing versioning and legacy path patterns.
• Unsafe consumption surfaces and excessive third-party URLs.
• LLM / AI Security with 18 adversarial probes across Quick, Standard, and Deep tiers, including system prompt extraction, instruction override, jailbreak techniques, data exfiltration, and token smuggling.

middleBrick parses OpenAPI 3.0, 3.1, and Swagger 2.0 with recursive $ref resolution and cross-references spec definitions against runtime findings. This highlights undefined security schemes, sensitive fields, deprecated operations, and missing pagination. For authenticated scanning (available from Starter tier and above), support includes Bearer, API key, Basic auth, and Cookie. Domain verification is enforced through DNS TXT records or an HTTP well-known file, ensuring only the domain owner can scan with credentials. The scanner forwards a restricted allowlist of headers to limit exposure.

The platform provides a Web Dashboard for scanning, viewing reports, tracking score trends, and downloading branded compliance PDFs. The CLI (middlebrick npm package) supports commands such as middlebrick scan <url> with JSON or text output. A GitHub Action enables CI/CD gating, failing the build when the score drops below a chosen threshold. The MCP Server allows scans from AI coding assistants including Claude and Cursor. The Pro tier adds scheduled rescans every 6 hours, daily, weekly, or monthly, diff detection across scans, email alerts (1 per hour per API), HMAC-SHA256 signed webhooks, and Slack or Teams notifications. Enterprise tiers include unlimited APIs, custom rules, SSO, audit logs, SLA-backed support, and dedicated assistance.

middleBrick does not fix, patch, block, or remediate findings; it detects and reports with remediation guidance. It does not perform active SQL injection or command injection testing, which requires intrusive payloads outside its scope. Business logic vulnerabilities are not detected, as they require human domain understanding. Blind SSRF and other out-of-band infrastructure tests are out of scope, and the scanner does not replace a human pentester for high-stakes audits. Safety measures include read-only methods only, blocking private IPs, localhost, and cloud metadata endpoints at multiple layers. Customer data is deletable on demand and purged within 30 days of cancellation, and it is never sold or used for model training.
