differential-review

To perform a security review on a git diff, you analyze the code changes to identify security-impacting modifications and new attack surfaces introduced in a pull request. This contextual review evaluates authentication, authorization, cryptography, and PII edits to prevent insecure changes from merging.

Differential code review analyzes git diffs in the broader project context rather than simple line-level scanning. It identifies vulnerabilities by classifying changes, reading surrounding code, evaluating altered trust boundaries, and providing high-confidence findings with concrete exploit scenarios.

Yes, this security review reduces noisy false positives by applying hard exclusion rules and assigning 1-10 confidence scores. It uses contextual reasoning to evaluate whether a change creates a real vulnerability, ensuring only actionable, high-confidence findings are promoted.

You can automate pre-merge security audits for authentication, cryptography, PII, infrastructure, dependency, and configuration edits. The review produces a structured report with remediation recommendations and a final verdict to gate pull requests and inform merges.

The best way to triage new attack surfaces in a code diff is to perform attack surface analysis that identifies new endpoints, changed trust boundaries, and data flow alterations. This contextual approach focuses reviewers on real exploit paths instead of isolated code changes.
