The Liability

Most AI workflows are an
uncontrolled liability.

Many standard AI workflows can expose sensitive company data if not properly controlled.

Your data leaves your control.

Standard API calls transmit employee names, client records, contract terms, and credentials to third-party AI providers — often without audit trails, consent records, or contractual protections adequate for your industry.

You're paying for tokens you don't need.

Filler language, pleasantries, and assistant boilerplate inflate every API request by 15–30%. At production scale, that margin leak becomes a line item that compounds every month.

You have no proof of compliance.

When an incident occurs, "we use a reputable AI provider" is not a defensible position. Without data custody logs and redaction records, you cannot demonstrate control — to regulators, clients, or your own legal team.

Data Shield

The AI never sees
the real data.

Data Shield intercepts every prompt before it leaves your device. Names become tokens. Emails become placeholders. Financial figures become variables. The AI only ever sees the shape of your data — never the substance.

  • PII Scrambling — names, emails, phone numbers
  • Credential Detection — API keys, passwords, tokens
  • Financial Figure Obfuscation
  • Entity Audit Trail per session
  • Zero-Persistence Architecture — no server storage
  • Ghost toggle — view original vs. transmitted
