PrivacyScrubber vs Skyflow Privacy Vault
Zero-Server Client-Side Masking vs Cloud Vault Infrastructure

Compare PrivacyScrubber local browser sanitization against Skyflow cloud vaults. Zero-trust in-browser tokenization without complex vault APIs.

Verdict: PrivacyScrubber wins for prompt protection and zero-ops deployments

Skyflow is a cloud privacy vault for tokenizing database records via REST APIs. However, for interactive AI workflows (ChatGPT, Claude), routing text through a cloud vault introduces high API latency, per-call billing, and vendor custody of sensitive tokens. PrivacyScrubber executes tokenization entirely in local browser RAM with $0 cloud infrastructure costs and zero network transit.

Where PrivacyScrubber Wins

Zero Third-Party Custody

Skyflow stores your tokenized PII in a hosted cloud vault, creating a high-value third-party honeypot. PrivacyScrubber uses ephemeral RAM mappings that disappear the moment your browser tab closes, eliminating persistent liability.

Instant Browser Integration

While Skyflow requires software engineers to integrate backend SDKs and restructure SQL queries, PrivacyScrubber protects ChatGPT, Claude, and Gemini immediately in the browser without writing a single line of code.

Flat Rate & Zero Per-Call Tax

Skyflow bills on API call volume and vault storage tiers. PrivacyScrubber provides flat-rate pricing with unlimited tokens, files, and prompts.

Deciding Which Tool is Right For You

Choose PrivacyScrubber if:

  • Protect employees using web chatbots (ChatGPT, Claude, Perplexity)
  • Need instant, client-side PII sanitization without backend development
  • Require a zero-server, air-gapped compliance posture
  • Want flat-rate pricing without metered API surcharges

Choose Skyflow Privacy Vault if:

  • Building a core fintech database requiring long-term cloud token storage
  • Need PCI DSS Level 1 payment card vaulting in cloud infrastructure
  • Have dedicated dev teams to integrate custom REST API privacy endpoints

Technical Architecture: Ephemeral RAM Token Maps vs Persistent Cloud Vaults

Skyflow is designed around the concept of a persistent cloud data privacy vault: sensitive customer records are extracted via backend REST APIs, encrypted with polymorphic encryption, and stored in a multi-tenant cloud vault while returning surrogate tokens to your database. For long-term database storage this is effective, but for real-time generative AI prompts it creates a high-latency external dependency and recurring per-call billing.

PrivacyScrubber enforces ephemeral, client-side tokenization. Instead of storing tokens in an external cloud vault, PrivacyScrubber isolates token mappings strictly within the browser tab's volatile RAM using tab-isolated scoping. When the browser tab closes or refreshes, the session map is instantly destroyed, leaving zero residual data footprint and satisfying SOC 2 Type II Zero-Retention Controls and PCI DSS Data Sanitization Standards.

Frequently Asked Questions

Is PrivacyScrubber a direct competitor to Skyflow?

Skyflow is designed for persistent database tokenization (replacing credit card and SSN columns in production SQL databases). PrivacyScrubber is purpose-built for ephemeral Generative AI prompt sanitization. For securing LLM prompts, PrivacyScrubber is vastly faster, cheaper, and safer because data never leaves endpoint RAM.

Does PrivacyScrubber require sending tokens to a vault?

No. PrivacyScrubber keeps token mappings in ephemeral browser memory. No tokens or original values are ever transmitted over the network or saved to disk.

How does latency compare between Skyflow and PrivacyScrubber?

PrivacyScrubber performs local in-memory tokenization in under 2ms. Skyflow REST API calls require 150ms to 400ms per tokenization/de-tokenization roundtrip.
