cfg-guard features
- Flock-based lock. Uses OS file lock (flock) to prevent simultaneous writes.
- Content-hash compare-and-swap. Refuses a write if the base file bytes have changed since read.
- Inotify + /proc writer identification. Detects and reports the process that attempted an out-of-order write.
- Standard-library only. No external dependencies; works with Python's stdlib.
- Simple installation. Install via pip with a single command.
- MIT licensed source. Open-source code hosted on GitLab.
Snyk features
- Automated AI Attack Protection. Scans AI-generated code artifacts for vulnerabilities at machine speed.
- Agentic Development Guardrails. Validates tools and code created by AI agents before they are committed.
- AI Application Governance. Provides inventory and policy enforcement for AI models, workflows, and agents in production.
- Continuous Offensive Security. AI-powered pentesting and red-team simulations to find chained business-logic flaws.
- AI Security Posture Management. Central dashboard with automated guardrails and risk scoring for AI workloads.
- IDE & CI/CD Integrations. Integrates with IDEs, pipelines, and AI coding assistants like Claude Code, Cursor, and Codex.
