PrivacyScrubber vs Google Cloud DLP
Zero-Trust Local Scrubber vs Cloud-Based DLP API
Google Cloud DLP API vs PrivacyScrubber compared. Why local client-side sanitization outperforms cloud API redaction for interactive AI prompts.
Verdict: PrivacyScrubber wins on zero-trust privacy and cost
Google Cloud DLP requires transmitting raw PII over the internet to Google's API endpoints, demanding strict HIPAA BAA signing. PrivacyScrubber runs 100% locally in browser RAM, meaning raw data never leaves the device and no BAA is required.
Feature-by-Feature Matrix
| Feature | PrivacyScrubber | Google Cloud DLP |
|---|---|---|
| Data Transmission | Zero — processed locally in RAM | Transmitted to Google Cloud servers |
| HIPAA BAA Requirement | Exempt (no data leaves device) | Mandatory (cloud data processor) |
| Network Latency | 0ms (local CPU speed) | Varies (network roundtrip required) |
| Chrome Extension UI | Yes — real-time inline | No (API endpoints only) |
| Reversible Redaction | Yes — local session map | Requires custom DB/key storage |
| Pricing Model | Flat rate — $15/mo or flat TEAMS | Pay-per-gigabyte api usage |
Where PrivacyScrubber Wins
Zero Transit Exposure
PrivacyScrubber does all regex and detection inside your browser. Google Cloud DLP requires you to send your raw, unredacted text over the public network to their servers, creating a transmission liability.
0ms Network Latency
Because redaction happens on the client's CPU, there is no network transit lag. Google Cloud DLP introduces latency for every API call, which slows down real-time chat interactions.
Simpler Security Reviews
Since PrivacyScrubber operates entirely on your device and does not receive or process your data, we do not act as a data processor. This helps you avoid complex Business Associate Agreements (BAAs) or the extended security reviews required for Google Cloud DLP.
Deciding Which Tool is Right For You
Choose PrivacyScrubber if:
- ✓Highly regulated industries (Healthcare PHI, Finance NPI)
- ✓Teams with zero budget for infrastructure setup
- ✓Real-time prompt protection in ChatGPT or Claude
- ✓Offline / air-gapped dev environments
Choose Google Cloud DLP if:
- →Already running a massive cloud architecture on Google Cloud
- →Masking millions of files sitting in Google Cloud Storage (GCS) buckets
- →Building backend microservices where API access is preferred over browser UI
Technical Architecture Trade-offs
The core difference between the two approaches is the underlying architecture. PrivacyScrubber enforces a Zero-Trust Data Sanitization (ZTDS) model: all processing is restricted to volatile browser RAM on the client side. Your PII never hits the disk, never goes through a microservice, and never creates persistent logging footprints.
For regulated operations (such as HIPAA safe harbor or GDPR data protection audits), this RAM-only design eliminates sub-processor exfiltration risks entirely. With cloud-based alternatives, your data is processed remotely, forcing your legal team to conduct extensive Vendor Risk Assessments and sign complex Data Processing Agreements (DPA).
Additionally, tokenization Swaps (e.g. replacing sensitive data with safe identifiers and then reversing them once the LLM responds) are natively implemented on the client. Tools that perform permanent redaction break the semantic context loop, causing AI models to produce inaccurate or generic results.

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 the API endpoints. PrivacyScrubber is inherently HIPAA compliant without a BAA because no data ever leaves the user's local browser runtime.
How does the cost compare?
Google Cloud DLP charges based on the amount of data processed (per GB), which can quickly escalate in a busy organization. PrivacyScrubber offers flat-rate pricing with no volume-based surcharges, making it highly predictable for security budgets.
