Compliance-focused API scanning for security and audit readiness

Organizations under pressure to demonstrate compliance require evidence-backed tooling that integrates into existing workflows. This scanner provides a self-service method to surface security issues aligned to recognized standards without requiring code access or agents.

It supports PCI-DSS 4.0, SOC 2 Type II, and OWASP API Top 10 (2023) by mapping findings to specific control areas. For other frameworks, it helps you prepare for audits by aligning with security controls described in relevant guidelines and by supplying findings that support audit evidence.

Because the approach is read-only, it avoids production impact while still validating authentication, authorization, input handling, and data exposure relevant to compliance expectations.

Black-box methodology and supported authentication

Being a black-box scanner means it operates without SDKs, agents, or access to source code, making it applicable to any language, framework, or cloud environment. Scan time remains under a minute for most endpoints.

Authenticated scanning is available for Bearer tokens, API keys, Basic auth, and Cookies. Before scanning with credentials, a domain verification gate confirms ownership via DNS TXT record or an HTTP well-known file, ensuring only the domain owner can submit authenticated checks.

Header forwarding is limited to Authorization, X-API-Key, Cookie, and X-Custom-* headers, reducing risk while still allowing necessary context for security checks.

Detection coverage across OWASP API Top 10 and related areas

The scanner covers 12 categories aligned to OWASP API Top 10, including Authentication bypass, Broken Object Level Authorization, Broken Function Level Authorization, and Sensitive Data Exposure.

  • Authentication checks multi-method bypass and JWT misconfigurations such as alg=none, weak algorithms, expired tokens, missing claims, and sensitive data in claims.
  • Authorization testing identifies IDOR via sequential ID enumeration and adjacent ID probing, along with privilege escalation through admin endpoint probing and role/permission leakage.
  • Input Validation covers CORS wildcard usage with and without credentials, dangerous HTTP methods, and debug endpoints.
  • Data Discovery identifies PII patterns such as email and context-aware SSN, common API key formats for AWS, Stripe, GitHub, and Slack, as well as error and stack-trace leakage.
  • LLM/AI Security performs 18 adversarial probes across Quick, Standard, and Deep tiers, including system prompt extraction, instruction override, jailbreak techniques, data exfiltration attempts, and token smuggling.

OpenAPI analysis is included for versions 3.0, 3.1, and Swagger 2.0, with recursive $ref resolution to compare spec definitions against runtime findings such as undefined security schemes or deprecated operations.

Reporting, integrations, and continuous monitoring options

The Web Dashboard centralizes scans, enabling review of prioritized findings, tracking score trends, and downloading branded compliance PDFs for stakeholder reporting.

CLI access through the middlebrick npm package supports scripted workflows with JSON or text output. The GitHub Action acts as a CI/CD gate, failing the build when the score drops below a defined threshold. An MCP Server allows scans from AI coding assistants such as Claude or Cursor.

For ongoing risk management, Pro tier provides scheduled rescans every 6 hours, daily, weekly, or monthly. Diff detection highlights new findings, resolved items, and score drift. Alerts are rate-limited to one email per hour per API, and webhooks use HMAC-SHA256 signing with auto-disable after five consecutive failures.

Limitations and safety posture

The tool does not fix, patch, block, or remediate issues; it detects and provides guidance for remediation. It does not execute active SQL injection or command injection tests, as those fall outside the read-only scope. Business logic vulnerabilities require human analysis tied to your domain, and blind SSRF is out of scope due to the lack of out-of-band infrastructure.

Safety measures include read-only methods only, blocking of private IPs, localhost, and cloud metadata endpoints at multiple layers, and strict data handling policies. Customer scan data is deletable on demand and purged within 30 days of cancellation, and it is never sold or used for model training.

Frequently Asked Questions

Does this replace a human pentester for compliance audits?
No. The scanner detects and reports findings with remediation guidance, but it does not replace a human pentester for high-stakes audits or certify compliance.
Which frameworks are explicitly mapped for compliance reporting?
Findings map directly to PCI-DSS 4.0, SOC 2 Type II, and OWASP API Top 10 (2023). Other frameworks are supported through alignment with described security controls.
Can authenticated scans be run in CI environments?
Yes, authenticated scans are supported with Bearer, API key, Basic auth, and Cookie, provided domain ownership is verified via the gate mechanism.
How are new or resolved findings tracked over time?
Pro tier continuous monitoring uses diff detection across scans to highlight new findings, resolved items, and score drift, with alerts delivered via email or webhook.
