Migrating from 42Crunch to middleBrick for GDPR Article 32 alignment
What middleBrick covers
- Black-box API scanning with risk score A–F under one minute
- 12 OWASP API Top 10 categories including LLM security probes
- OpenAPI 3.0/3.1 and Swagger 2.0 parsing with $ref resolution
- Authenticated scans with domain verification and header allowlist
- Continuous monitoring with diff detection and alerting
- GDPR Article 32 aligned reporting without compliance claims
Assessment coverage and scope difference
Migrating from 42Crunch to middleBrick changes the scope of what you scan and how you scan it. middleBrick is a black-box API security scanner that submits read-only HTTP methods to surface risks without code access, agents, or SDKs. You submit a URL and receive a risk score from A to F with prioritized findings within under a minute. Where 42Crunch may rely on instrumentation or preconditions, middleBrick operates against the live API surface using GET and HEAD, plus text-only POST for LLM probes.
Mapping findings to compliance frameworks
middleBrick maps findings directly to three frameworks: PCI-DSS 4.0, SOC 2 Type II, and OWASP API Top 10 (2023). For every finding, you receive guidance on how the result aligns with security controls described in these standards. The scanner helps you prepare for audits by surfacing findings relevant to GDPR Article 32, such as data exposure and encryption checks, without claiming certification or compliance.
In contrast, 42Crunch often references its own taxonomy, which can require re-mapping to audit frameworks. With middleBrick, the output is framed in familiar control sets, reducing the manual work needed to translate results into audit evidence.
Authentication and authorized scanning workflow
middleBrick supports authenticated scans using Bearer tokens, API keys, Basic auth, and cookies. Before you authenticate, domain verification is required: the system checks a DNS TXT record or an HTTP well-known file to confirm you control the domain. Only then are your credentials used, and only specific headers such as Authorization, X-API-Key, Cookie, and X-Custom-* are forwarded.
For GDPR Article 32, this gate ensures that scanning is limited to your owned endpoints. 42Crunch may have different auth models that do not always enforce the same domain ownership check, which can complicate evidence collection during audits.
LLM and input validation security
The scanner includes specific coverage for LLM/AI Security with 18 adversarial probes across Quick, Standard, and Deep tiers. These probes test for system prompt extraction, instruction override, DAN and roleplay jailbreaks, data exfiltration, token smuggling, and related attack chains. Input validation checks include CORS wildcard configurations, dangerous HTTP methods, and debug endpoints.
While 42Crunch focuses heavily on API schema and runtime behavior, middleBrick adds explicit testing for prompt injection and model abuse vectors that are increasingly relevant to GDPR Article 32 when personal data is processed by AI endpoints.
Operational reporting and monitoring differences
middleBrick provides a web dashboard for scanning, viewing reports, tracking score trends, and downloading branded compliance PDFs. The CLI allows quick scans with JSON or text output, and a GitHub Action can fail builds when scores drop below a set threshold. Pro tier adds scheduled rescans, diff detection across scans, email alerts rate-limited to one per hour per API, and HMAC-SHA256 signed webhooks that auto-disable after five consecutive failures.
Compared to 42Crunch, this approach emphasizes continuous monitoring and CI/CD integration without requiring proprietary agents. You retain control of scan data, which is deletable on demand and purged within 30 days of cancellation, aligning with data minimization expectations under GDPR Article 32.
