Migrating from 42Crunch to Nuclei

Migrating from a specialized API security scanner to a different solution involves comparing detection models, coverage scope, and operational workflows. This guide outlines the practical steps to move configurations and scans while acknowledging gaps that require manual follow-up.

Export findings from the source platform in its native report format, typically JSON or PDF, and retain the raw scan artifacts if available. Rebuilding historical dashboards is not automatic; you will map findings to severity levels and frameworks such as OWASP API Top 10 (2023) to preserve trend visibility in the new toolchain.

• Download comprehensive reports for each scanned API.
• Record scan timestamps, target inventories, and authentication contexts.
• Map existing severity ratings to the new platform risk scoring model.

Note that qualitative context, such as assumed business logic assumptions, does not transfer and must be re-established manually.

Recreate pipeline integrations by exporting CI job definitions and environment variables used in the original scanner. Reconfigure the pipeline to invoke the new tool using its CLI or API client, ensuring that gate thresholds and failure conditions are redefined based on the new platform limits. Common patterns include passing a target URL list and setting a score threshold that blocks promotion when findings are present.

Validate that only read-only methods are exercised and that authentication tokens are sourced from secure vaults. Adjust scheduling to respect rate limits and avoid unintended resource consumption during parallel runs.

Understand that no scanner replaces contextual analysis for business logic flaws. The new toolset will surface findings aligned to standards such as PCI-DSS 4.0, SOC 2 Type II, and OWASP API Top 10 (2023), but validation of controls may require manual test cases for scenarios like complex multi-step workflows or nuanced authorization checks.

• Confirm supported authentication methods, such as Bearer, API key, Basic auth, and Cookie, and verify header allowlists.
• Check whether sensitive data exposure detection includes PII patterns and API key formats relevant to your tech stack.
• Review coverage of advanced probe types, such as those for LLM/AI security or SSRF indicators, against your risk profile.

Supplemental manual testing or targeted scripts may be necessary to close blind spots that scanners cannot safely probe.

Plan for ongoing operations by configuring scheduled rescans, alerting cadence, and notification channels. Set up email alerts at sensible rate limits, such as one per hour per API, and verify webhook signatures using HMAC-SHA256 to ensure integrity of automated events. For long-term management, define compliance report generation cadence and retention policies for scan data in line with data governance requirements.

Establish a clear demarcation of responsibilities: the scanner detects and reports, while your team determines remediation priority and validates fixes. Use the platform to track score trends and to export evidence for audit purposes where applicable.
