Arnica Secrets Security vs Gitleaks

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.

Gitleaks is free, MIT-licensed software that detects secrets such as passwords, API keys, and tokens in Git repositories, files, and standard input. It runs on Linux, macOS, Windows, and self-hosted systems. Scans can target repositories, directories, individual files, or streamed data. Custom rules can use Go regular expressions, entropy checks, path matching, keywords, and allowlists. A previous report can serve as a baseline so later scans show only new findings. Output is available in JSON, CSV, JUnit, SARIF, or template formats. The project documents pre-commit hook and GitHub Action use, plus CI/CD, pull-request, and supported VCS workflows for GitHub, GitLab, Azure DevOps, Gitea, and Bitbucket. Installation options include Homebrew, Docker, Go, and prebuilt release binaries. A redaction option masks secrets in logs and standard output, with a default redaction value of 100%. The project describes itself as feature complete, with future releases limited to security patches, and its security policy supports only the latest version.
