Enterprise Security & Guardrails
Can I build an AI compliance and security stack entirely from open-source tools?
Yes — you can cover PII redaction, guardrails, red teaming, evaluation, and compliance automation without a single license fee. The stack: 1. PII redaction: Microsoft Presidio detects and anonymizes PII before data reaches an LLM API. 2. Guardrails: NeMo Guardrails for programmable conversational rails, or Guardrails AI for composable output validators. 3. Red teaming: Garak for baseline vulnerability scans plus PyRIT for multi-turn adversarial testing. 4. Evaluation: DeepEval for pytest-style LLM tests, Ragas if you run RAG pipelines, Giskard for model scanning. 5. Compliance automation: Comp AI (AGPLv3) as a self-hostable alternative for SOC 2 and ISO 27001 workflows. The frameworks are free too: NIST AI RMF and the OWASP LLM Top 10 cost nothing to adopt. The trade-off is maintenance: after LLM Guard was archived in July 2026, the practical rule is to check every repo's activity before you build on it — and keep one migration path documented per critical tool.
