Cypherz vs Microsoft Presidio
Cypherz vs Microsoft Presidio
Presidio is Microsoft's open-source PII detection toolkit — Python library, customizable recognizers, well-documented. It's a great starting point if your engineering team has the cycles to wire detection into an LLM proxy themselves. Cypherz is what you get when you don't want to build the rest: proxy + audit + files + multi-tenant + dashboard.

Common questions
Frequently asked.
Is Cypherz a direct replacement for Microsoft Presidio?
For developer-shaped AI integrations — yes, and you'll likely ship faster. For enterprise-shaped data privacy vault deployments with central PII storage as the goal, Microsoft Presidio remains the more mature pick.
Can I migrate from Microsoft Presidio to Cypherz?
Yes. Tokenization mappings are project-scoped on both products; you can rotate keys and re-tokenize within a maintenance window. We've helped customers migrate in under a day.
Does Cypherz sign a BAA / DPA?
Yes, at Business and Enterprise tiers we sign BAAs (HIPAA) and DPAs (GDPR). Free and Pro tiers do not include signed agreements but use the same encryption and audit primitives.
Where is Cypherz hosted?
EU (Hetzner — Helsinki and Falkenstein) by default for the managed product. Self-host anywhere with one docker-compose command.
