anonymize.solutions vs Presidio DIY
We built on Microsoft Presidio’s excellent detection foundation and added everything you need for production: managed infrastructure, integrations, and enterprise support.
TL;DR
anonymize.solutions is a managed service built on Presidio’s detection core, adding Zero-Knowledge architecture, MCP Server, Office Add-in, Chrome Extension, managed hosting, and confidence scoring with context-aware validation for higher accuracy. Microsoft Presidio is a free open-source Python library that requires you to build, deploy, scale, and maintain everything yourself.
Choose anonymize.solutions for production-ready deployment with support. Choose Presidio DIY if you have dedicated engineering resources and want full control over every layer.

What You Get, What You Build, What We Add
Presidio is an excellent detection engine. But a detection engine is not a product. Here’s what it takes to go from library to production service.
What Presidio Gives You
- PII detection engine (Python)
- Extensible recognizer framework
- 50+ built-in entity types
- spaCy NLP integration
- Anonymization operators
- Active open-source community
What You Must Build
- Production hosting & deployment
- Auto-scaling infrastructure
- REST API layer with auth
- Monitoring & alerting
- Security hardening
- Ongoing updates & patching
- User-facing integrations
- Error handling & retry logic
What We Add
- All of the above, managed
- 317 custom regex recognizers
- MCP Server for AI workflows
- Office Add-in for Word
- Chrome Extension for AI chat
- Desktop App (online + air-gapped)
- Zero-Knowledge encryption
- 317 custom regex recognizers
The True Cost of “Free”
Presidio is free to download. But deploying, securing, scaling, and maintaining it in production is not. Here’s a realistic cost comparison.
anonymize.solutions
- Setup: Hours (API key + integration)
- Initial build: None
- Ongoing maintenance: None
- Infrastructure: Included
- Monitoring: Included
- Updates: Automatic
- Support: Dedicated team
- Total: Predictable subscription
Presidio DIY (“Free”)
- Setup: 2 – 4 weeks engineering
- Initial build: API, auth, deployment pipeline
- Ongoing maintenance: 20 – 40 hrs/month
- Infrastructure: Cloud hosting + scaling
- Monitoring: Build + maintain
- Updates: Manual testing + rollout
- Support: Your own team
- Total: Free license + significant engineering cost
Note: Engineering time estimated at industry-standard rates for backend Python developers with NLP experience. Actual costs vary by team size, cloud provider, and compliance requirements.
What Presidio Lacks Out-of-the-Box
Presidio is a Python library. Everything beyond the detection engine — every integration, every interface, every security layer — must be built and maintained by your team.
- MCP Server for AI workflows — Connect Claude Desktop, Cursor, VS Code to anonymization with 6 operators and entity groups
- Chrome Extension for browser protection — Real-time PII interception on ChatGPT, Claude, and Gemini with response de-anonymization
- Office Add-in for document processing — One-click anonymization in Microsoft Word with format preservation
- Desktop App for local/air-gapped use — Encrypted vault, batch processing, offline mode with local NLP models
- Managed API with auth and rate limiting — JWT authentication, usage tracking, and automatic scaling without a single line of infrastructure code
- Zero-Knowledge encryption layer — Argon2id + XChaCha20-Poly1305 ensuring your data is never visible to us or any third party
The integration math
Building just one of these integrations from scratch takes 2–8 weeks of engineering time. We ship six production-ready integrations on day one, fully maintained and updated automatically. That’s 12–48 weeks of engineering you never have to do.
Migration Path from Presidio DIY
Already running Presidio? Moving to anonymize.solutions is straightforward. We built on the same foundation, so your customizations transfer directly.
-
Keep your custom recognizers
We support Presidio-format recognizers natively. Your custom entity patterns, deny lists, and regex recognizers work without modification. Upload via API or UI.
-
Point API calls to our managed endpoint
Replace your self-hosted Presidio URL with our managed API endpoint. Request and response formats are compatible — most migrations require changing a single environment variable.
-
Remove your infrastructure — we handle it
Decommission your Presidio servers, monitoring stack, and deployment pipeline. We manage hosting, scaling, updates, and security on EU infrastructure with 100% uptime SLA.
Stop maintaining infrastructure. Start protecting data.
Get production-ready PII detection and anonymization with managed infrastructure, enterprise integrations, and dedicated support — all built on the Presidio foundation you already trust.
