PrivacyScrubber vs Philter (Phileas)
In-Process <1ms SDK, Python MCP & Browser DLP vs JVM Redaction Containers

Compare PrivacyScrubber vs Philter (Phileas): 150KB <1ms in-memory SDK, Python PyPI MCP, Apache-2.0 ZTDS™, and browser DLP vs JVM Docker containers.

Verdict: PrivacyScrubber wins on <1ms in-process SDK speed, zero JVM container overhead, and turnkey browser DLP

Philter (and its Apache-2.0 open-source core Phileas) is a Java/JVM-based redaction server that requires running Docker containers, managing JVM heap memory, and making out-of-process HTTP calls. PrivacyScrubber combines an Apache-2.0 open-source ZTDS™ baseline (ztds-mcp / npx ztds-audit) with a 150KB zero-dependency Node.js/TypeScript SDK (<1ms in RAM), a Python PyPI MCP server (pip install privacyscrubber-mcp), a <60MB Alpine sidecar, and a zero-install Chrome Extension & Web Workspace.

Technical Architecture: 150KB In-Process WASM/JS & Python MCP vs JVM Container Services

When engineering teams search for Microsoft Presidio alternatives, Philter (and its Apache-2.0 open-source engine, Phileas) is frequently evaluated because it provides turnkey filter profiles and avoids Python/spaCy dependencies. However, Phileas is architected on the Java Virtual Machine (JVM). Running it in modern TypeScript, Node.js, or Python AI stacks still requires deploying an out-of-process JVM Docker container, allocating 300MB–600MB+ of heap memory, and incurring HTTP serialization latency on every prompt.

PrivacyScrubber eliminates the JVM and container layer altogether while matching Philter's dual open-source + commercial turnkey model:

  • Open-Source Apache-2.0 Standard: Our Zero-Trust Data Sanitization (ZTDS™) reference tools (npx ztds-audit and ztds-mcp) are 100% open-source under the Apache-2.0 license, governed by IETF draft-sibiryakov-ztds-protocol.
  • In-Process Node.js & TypeScript SDK (@privacyscrubber/sdk): A ~150KB zero-dependency engine executing in <1ms in local RAM with 1-line wrapOpenAI() bijective de-tokenization.
  • Python & Polyglot Sidecars: Install pip install privacyscrubber-mcp for LangChain, LlamaIndex, and CrewAI, or deploy our <60MB Alpine Docker Sidecar and Python FastAPI Sidecar (<1.2ms).
  • 30 Turnkey Vertical Profiles + Browser DLP: Out-of-the-box coverage for HIPAA Safe Harbor (§164.514(b)), PCI-DSS Level 1, SWIFT, and Defense CMMC across both backend SDKs and our Manifest V3 Chrome Extension.

Frequently Asked Questions

How does PrivacyScrubber compare to Philter and Phileas for Microsoft Presidio users?

Both Philter (Phileas) and PrivacyScrubber solve Microsoft Presidio's heavy Python/spaCy NLP overhead and offer an Apache-2.0 open-source foundation paired with commercial turnkey profiles. However, Phileas is a Java/JVM server requiring Docker container orchestration, whereas PrivacyScrubber runs in-process in <1ms via a 150KB Node.js/TypeScript SDK (@privacyscrubber/sdk), a Python PyPI MCP package (pip install privacyscrubber-mcp), a <60MB Alpine sidecar, and a browser extension.

Does PrivacyScrubber offer an Apache-2.0 open-source option like Phileas?

Yes. The reference Zero-Trust Data Sanitization standard implementation (ztds-mcp and npx ztds-audit) is licensed under Apache-2.0. Teams needing 30 specialized industry profiles, 1-line wrapOpenAI() SDK wrappers, offline PDF/OCR scrubbing, and centralized team governance upgrade to PrivacyScrubber PRO, TEAMS ($99/mo), or Developer SDK ($299/mo).

Which tool is better for LLM prompt protection: PrivacyScrubber or Philter?

PrivacyScrubber provides both a 1-line backend LLM wrapper (wrapOpenAI) that automatically restores bijective tokens ([NAME_1]) in RAM and a Manifest V3 Chrome Extension that protects employees typing directly into ChatGPT, Claude, and Gemini. Philter operates strictly as a backend server or API proxy without a browser extension.
