Alternatives to APIsec for Security architects

What middleBrick covers

  • Black-box scanning with risk score and prioritized findings
  • Covers 12 OWASP API Top 10 (2023) categories
  • OpenAPI 3.0/3.1 and Swagger 2.0 parsing with $ref resolution
  • Authenticated scanning with strict domain verification
  • Continuous monitoring with diff detection and alerts
  • Integrations including CLI, GitHub Action, and MCP Server

Black-box scanning approach

The tool operates as a black-box scanner. You submit a URL and receive a risk score from A to F with prioritized findings. It does not require agents, SDKs, or code access and supports any language, framework, or cloud. Only read-only methods are used, and scan completion typically occurs in under a minute.

Detection coverage aligned to standards

The scanner covers 12 categories aligned to the OWASP API Top 10 (2023). It maps findings to PCI-DSS 4.0 and SOC 2 Type II where relevant, and supports audit evidence for these frameworks. Detection includes authentication bypass, JWT misconfigurations such as alg=none or expired tokens, BOLA and IDOR via sequential ID probing, BFLA and privilege escalation attempts, property over-exposure, input validation issues like CORS wildcard usage, rate-limit header detection, data exposure including PII and API key patterns, encryption checks, SSRF indicators, and inventory management concerns.

OpenAPI and authenticated scanning

The tool parses OpenAPI 3.0, 3.1, and Swagger 2.0 with recursive $ref resolution and cross-references spec definitions against runtime results. Authenticated scanning is available starting at the Starter tier and supports Bearer, API key, Basic auth, and Cookie methods. Domain verification is enforced so that only the domain owner can scan with credentials, and a restricted header allowlist is applied.

Continuous monitoring and integrations

Pro tier options include scheduled rescans at intervals from 6 hours to monthly, diff detection across scans, email alerts rate-limited to one per hour per API, and HMAC-SHA256 signed webhooks that auto-disable after 5 consecutive failures. Integration options include a Web Dashboard for reporting and trends, a CLI via an npm package, a GitHub Action for CI/CD gating, an MCP Server for AI coding assistants, and a programmable API for custom workflows.

LLM security and scope limitations

The scanner includes 18 adversarial probes across Quick, Standard, and Deep tiers targeting LLM/AI Security, such as system prompt extraction, instruction override, DAN and roleplay jailbreaks, data exfiltration, token smuggling, and nested instruction injection. The tool does not perform active SQL injection or command injection, does not fix or remediate findings, and does not detect business logic vulnerabilities or blind SSRF. It is not a replacement for a human pentester in high-stakes audits.

Data handling, safety, and pricing

Scan data is deletable on demand and purged within 30 days of cancellation. Private IPs, localhost, and cloud metadata endpoints are blocked at multiple layers. The product does not use customer data for model training or any form of transfer. Pricing tiers include a free plan with 3 scans per month and CLI access, Starter at 15 APIs with dashboard and email alerts, Pro with continuous monitoring and CI/CD integration, and Enterprise with unlimited APIs and dedicated support.

Frequently Asked Questions

Does the tool actively exploit vulnerabilities?
No. The scanner only uses read-only methods and never sends destructive payloads. It detects and reports findings with remediation guidance.
Which API specifications does it parse?
It parses OpenAPI 3.0, 3.1, and Swagger 2.0, resolving recursive $ref definitions and comparing spec definitions to runtime behavior.
How are webhook notifications secured?
Webhooks are signed using HMAC-SHA256 and will be automatically disabled after 5 consecutive delivery failures.
Can authenticated scans be performed?
Yes, authenticated scanning is available from the Starter tier onward, supporting Bearer, API key, Basic auth, and Cookie methods with domain ownership verification.
Does the tool provide compliance certifications?
It does not certify compliance. It supports audit evidence for frameworks such as PCI-DSS 4.0 and SOC 2 Type II and aligns with security controls described in OWASP API Top 10 (2023).
