PrivacyScrubber vs Google Cloud DLP
In-Process <1ms SDK, Python MCP & Browser RAM vs Metered Cloud DLP API
Google Cloud DLP API alternative: replace 300ms cloud roundtrips and per-GB fees with PrivacyScrubber's <1ms in-memory SDK, Python MCP, and browser DLP.
Verdict: PrivacyScrubber wins on <1ms in-process SDK speed, zero cloud egress, and flat-rate cost
Google Cloud DLP (Sensitive Data Protection) requires transmitting raw PII over the internet to Google's API endpoints, adding 150–350ms of network latency, demanding HIPAA BAA signing, and charging metered per-GB fees. PrivacyScrubber runs 100% locally in application RAM via our 150KB Node.js/WASM SDK (<1ms), Python PyPI MCP server, and zero-install Chrome Extension with $0 per-GB API fees.

Zero-Docker In-Memory PII Engine in Under 60 Seconds
Replace 500MB+ Python NLP containers and cloud DLP APIs with a synchronous in-memory engine (<1ms in volatile RAM).
import OpenAI from 'openai';
import { wrapOpenAI } from '@privacyscrubber/sdk';
// Transparently wrap client: prompts sanitized in RAM, responses restored automatically
const openai = wrapOpenAI(new OpenAI({ apiKey: process.env.OPENAI_API_KEY }));
const res = await openai.chat.completions.create({
model: 'gpt-4o',
messages: [{ role: 'user', content: 'Audit patient John Doe (MRN-99281) for asthma treatment.' }]

Technical Architecture: In-Process RAM Sanitization vs Remote Cloud API Hops
Google Cloud DLP (Sensitive Data Protection) requires sending raw, unredacted payloads over HTTPS to Google's cloud endpoints. In synchronous LLM and RAG applications, this introduces a 150ms–350ms network latency penalty per call, creates an external data subprocessor relationship, and incurs metered per-GB inspection charges ($1.00 to $3.00 per GB).
PrivacyScrubber enforces Zero-Trust Data Sanitization (ZTDS) in-process. Backend engineers drop in @privacyscrubber/sdk (see our Google Cloud DLP In-Memory Node.js Migration Guide and Python FastAPI Local Sidecar) to sanitize text in <1ms in local RAM with 1-line wrapOpenAI() auto-detokenization. Verify live speeds on the Interactive DLP Latency Benchmark Tool.
Under HIPAA Safe Harbor Compliance and GDPR Article 25 (Privacy by Design), eliminating cloud transmission eliminates third-party processor risk. Compare with Microsoft Presidio and Nightfall AI.

Frequently Asked Questions
Is Google Cloud DLP HIPAA compliant?
Yes, Google Cloud DLP is HIPAA compliant but only if you sign a Business Associate Agreement (BAA) with Google and properly secure your API keys and IAM roles. PrivacyScrubber is inherently compliant without a BAA because no PHI ever leaves the user's local browser runtime.
How does the cost compare between Google Cloud DLP and PrivacyScrubber?
Google Cloud DLP charges metered rates based on data volume processed ($1.00–$3.00 per GB), which creates unpredictable cloud bills as AI adoption grows. PrivacyScrubber offers flat-rate pricing with no volume surcharges or seat caps.
Can Google Cloud DLP protect ChatGPT prompts in real time?
No. Google Cloud DLP does not provide a Chrome Extension or browser interface. Integrating it with ChatGPT requires custom proxy servers or browser extension development. PrivacyScrubber provides an instant, plug-and-play Chrome Extension out of the box.
