Kingfisher – secret‑scanning and live validation tool

Kingfisher is a fast secret‑scanning and live validation tool. It combines Intel’s hardware‑accelerated Hyperscan regex engine with language‑aware parsing via Tree‑Sitter, and ships with hundreds of built‑in rules to detect, validate, and triage secrets before they ever reach production.

Kingfisher originated as a fork of Praetorian’s Nosey Parker.

This is free and open source software.

Features include:

  • Performance: multithreaded, Hyperscan‑powered scanning built for huge codebases
  • Extensible rules: hundreds of built-in detectors plus YAML-defined custom rules.
  • Multiple targets:
    • Git history: local repos or GitHub/GitLab orgs/users
    • Docker images: public or private via –docker-image
    • Jira issues: JQL‑driven scans with –jira-url and –jql
    • Confluence pages: CQL‑driven scans with –confluence-url and –cql
    • Slack messages: query‑based scans with –slack-query
    • AWS S3: bucket scans via –s3-bucket/–s3-prefix with credentials from KF_AWS_KEY/KF_AWS_SECRET, –role-arn, –aws-local-profile, or anonymous
  • Compressed Files: Supports extracting and scanning compressed files for secrets
  • Baseline management: generate and track baselines to suppress known secrets
