Migrating from OWASP ZAP to middleBrick
What middleBrick covers
- Black-box scanning with no agents or code access
- Risk scoring A–F with prioritized findings
- OpenAPI 3.0/3.1 and Swagger 2.0 parsing with ref resolution
- Authenticated scans with header allowlist controls
- LLM security probes across tiered scan levels
- Continuous monitoring and diff detection in Pro tier
Planning your migration from OWASP ZAP
Moving from OWASP ZAP to a self-service scanner changes how you initiate and consume security testing. With middleBrick, you submit a target URL and receive a risk score and prioritized findings within a minute. There are no agents, SDKs, or build integrations to maintain, and the scanner operates read-only with GET and HEAD methods plus text-only POST for LLM probes. Plan your cutover in stages: inventory your current ZAP configurations, export scan artifacts, and define the risk thresholds that will gate your CI/CD pipeline.
Exporting and mapping ZAP data
OWASP ZAP stores findings in its database and can export session data via the API or command line. Use the ZAP API to pull alerts, sites, and active scan results, then map ZAP alert names to the 12 categories aligned to OWASP API Top 2023 covered by middleBrick. Note that explicit request/response pairs and custom scripts will not transfer; you will rebuild test coverage using target URLs and optional authentication. MiddleBrick cross-references spec definitions against runtime findings, which can highlight undefined security schemes or deprecated operations that were previously undocumented in ZAP.
Rebuilding scan history and CI wiring
Historical scan data from ZAP does not import directly; you will re-scan critical APIs to establish a new baseline. Use the middleBrick CLI to automate this: middlebrick scan https://api.example.com, with JSON output for ingestion into dashboards or issue trackers. Wire the CLI into your existing CI pipeline as a gate, failing the build when the score drops below your chosen threshold. If you used ZAP’s automation framework, replace those hooks with equivalent CI commands, keeping the same trigger conditions for each service or repository.
What you will miss and what you gain
You will no longer run local proxies or manage ZAP context files, session handling, and add-on configurations. MiddleBrick does not execute intrusive payloads such as active SQL injection or command injection, and it does not detect business logic vulnerabilities, blind SSRF, or provide client-side exploit paths that ZAP can simulate. What you gain is a standardized, low-overhead workflow that works for any language or framework, OpenAPI spec validation, authenticated scanning with domain verification, and continuous monitoring with diff detection across scans. The tool surfaces findings relevant to PCI-DSS 4.0, SOC 2 Type II, and OWASP API Top 10, and it supports audit evidence for compliance preparation without claiming certification.
Operational considerations and rollout
During the transition, run middleBrick in parallel with ZAP on a subset of APIs to compare coverage and severity classifications. Configure authenticated scans only after domain verification, which requires a DNS TXT record or an HTTP well-known file proving ownership. Limit forwarded headers to Authorization, X-API-Key, Cookie, and X-Custom-* to avoid leaking secrets. Enable Pro-tier continuous monitoring for scheduled rescans and diff alerts if you need ongoing score tracking. Remember that middleBrick is a scanning tool; it does not remediate, and human review remains necessary for business logic and high-stakes audits.
