BUILD VS BUY

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
TOTAL COST OF OWNERSHIP

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.

INTEGRATION GAP

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

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.

  1. 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.

  2. 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.

  3. 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.

Honest Assessment

When Presidio DIY Might Be the Better Choice

anonymize.solutions is the right choice for most teams, but there are genuine scenarios where self-hosting Presidio makes more sense. We'd rather you make the right decision than the wrong one.

Zero External Dependency

If your threat model treats any third-party API as unacceptable — even Zero-Knowledge — then open-source Presidio with no commercial dependency is the appropriate path. However, this trade-off means you own 100% of the maintenance burden.

Deep Custom Recognizer R&D

Presidio's source code is fully forkable. If your use case requires deeply custom NLP model training that doesn't fit our entity definition system, self-hosting gives you that flexibility. The limitation is the 12-month TCO, which typically reaches $42K–$113K.

Academic / Research Use

For university research, non-commercial experimentation, or courses on privacy engineering, Presidio's open-source license has no drawback. anonymize.solutions is a commercial product and doesn't offer free tiers for academic research.
