Arnica Secrets Security vs KeyHog

Arnica Secrets Security detects and validates hardcoded secrets in code repositories. For newly pushed validated secrets, it can automatically rewrite commits and remove secrets from Git history. Severity considers validation context, including whether credentials belong to a highly privileged or development account. Codebases are scanned daily, with secrets revalidated on code changes and scheduled scans. Integrations include GitHub, GitLab, Azure DevOps, and Bitbucket; alerts can go to Slack or Microsoft Teams, while tickets can be created through Jira or Azure DevOps Boards. Teams can configure regex-based detectors, ignored paths, and policies for scanning and resolution. Arnica says it does not persist source-code snippets containing detected secrets and that customer data is encrypted at rest with tenant separation. Its cloud infrastructure is hosted on AWS, with TLS 1.2 or 1.3 in transit and AES 256 at rest. The Free plan's data ingestion runs every seven days; premium plans run in real time. Prices are per identity per year: Free is free, Business is $300 a year, and Enterprise is $600 a year. A 14-day trial is available.

KeyHog is free, open-source Rust software for finding and verifying exposed API keys, tokens, passwords, and other credentials. It scans source repositories and Git history, archives, Docker images, URLs and HAR captures, collaboration content, VCS inventories, cloud-storage inventories, browser assets, and running systems. The project lists 934 service-specific detectors, decode-before-scanning, contextual evidence and suppression, and optional live provider verification. GPU execution can use CUDA, native Metal, or portable WGPU, with calibration selecting a parity-backed option. Its GitHub Action scans checked-out trees, fails on high or critical findings, uploads SARIF to Code Scanning, and retains a workflow artifact. Documented CI integrations include GitLab, CircleCI, Jenkins, Buildkite, and shell jobs. A Unix daemon checks changed repository blobs before commits; Windows uses in-process scanning. KeyHog runs on Linux, macOS, Windows, and self-hosted deployments, and requires Rust 1.89 or newer. Code and detector TOMLs are licensed MIT OR Apache-2.0. The plan costs nothing.
