## Why Web Security Regression Scanner ranks for security search

Web Security Regression Scanner is an **offline-first**, research-grade **web application security** utility designed for practitioners who need reproducible analysis without uploading sensitive artifacts to SaaS scanners. It emits structured findings through the shared **secintel** evidence taxonomy (OBSERVED / DERIVED / INFERRED / CORRELATED / VERIFIED) so results are auditable, exportable, and CI-friendly.

## What problem does this solve?

Snapshot web security posture and detect regressions against a known-good baseline for release confidence.

Diff-aware web posture gates vs one-off scans.

## Key features

- Posture snapshots

• Baseline diffing

• Regression alerts

• CI-friendly outputs

• Offline comparisons

  Ideal use cases

  • Block regressions in CI

• Compare staging vs prod

• Track hardening over time

  Who should use this

  • Security engineers & AppSec / NetSec specialists
  • SOC / DFIR / malware analysts (as applicable)
  • Bug bounty hunters and penetration testers
  • DevSecOps teams needing offline/air-gapped tooling
  • Students and researchers learning web application security

  Quick start

  git clone https://github.com/reshot2005/web-security-regression-scanner.git
