DevSecOps-owned API security

Teams that integrate security checks into pull requests and pipelines reduce findings late in the release cycle. When API security is treated as a separate gate, issues surface closer to production, increasing remediation cost and operational disruption.

Without ownership, security becomes an afterthought: tests run manually, reports sit in email threads, and critical findings are deprioritized against feature work. Owning the workflow means scans are triggered on merge, results are visible in familiar tooling, and risk thresholds are enforced before code reaches production.

Skipping automated checks increases exposure to common API weaknesses such as broken authentication, excessive data exposure, and insecure default configurations. These issues are often missed in manual reviews because they require testing many endpoints with varied inputs and authentication contexts.

Another gap is the lack of continuous monitoring. APIs change frequently; without scheduled scans, new endpoints or debug routes may remain undetected. Teams also risk inconsistent compliance evidence when controls are validated only during annual assessments rather than on every change.

A robust workflow integrates scanning early and often. Start by running scans in local development or pre-commit hooks using the CLI to catch issues before code review. Merge checks in CI use the GitHub Action to enforce a minimum risk score and fail builds when critical findings appear.

In production, use the Pro tier for scheduled rescans and diff detection so new risks are surfaced as soon as they appear. Security and engineering can track score trends in the dashboard, correlate findings with specific PRs, and generate compliance artifacts that map to OWASP API Top 10, SOC 2 Type II, and PCI-DSS 4.0 requirements.

Example CLI usage in a pipeline:

middlebrick scan https://api.example.com/openapi.json --output json --threshold C

Example GitHub Action configuration:

uses: middlebrick/action@v1
with:
  url: openapi.json
  threshold: B
  alerts: true

middleBrick is a black-box API security scanner that requires no agents or SDKs. Submit an OpenAPI specification or a reachable endpoint and receive a letter-grade risk score with prioritized findings within minutes. The scanner exercises read-only methods and text-only POST probes to validate behavior without modifying state.

It parses OpenAPI 3.0, 3.1, and Swagger 2.0 with recursive $ref resolution and cross-references spec definitions against runtime behavior. Detection categories include authentication bypass, broken object level authorization, injection surfaces, rate limiting issues, data exposure, SSRF indicators, unsafe third-party callbacks, and LLM-specific adversarial probes across multiple depth tiers.

Authenticated scanning supports Bearer tokens, API keys, Basic auth, and cookies, protected by a domain verification gate to ensure only domain owners can submit credentials. The tool respects a strict header allowlist and does not attempt to remediate or patch findings.

Pro tier enables scheduled rescans at intervals from six hours to monthly, with diff detection that highlights new findings, resolved findings, and score drift. Alerts are rate-limited to one per hour per API and delivered by email or through HMAC-SHA256 signed webhooks that auto-disable after five consecutive failures.

For audits, the platform helps prepare evidence by surfacing findings relevant to control validation across OWASP API Top 10, SOC 2 Type II, and PCI-DSS 4.0. Reports can be downloaded as signed PDFs that reflect the state of an API at a point in time. Data deletion and retention policies allow on-demand removal, with purges completed within 30 days of cancellation.
