Process
How it Works
Intercept Inbound
Mask intercepts data entering LLMs and encrypts sensitive fields.
Format-Preserved Tokens
LLMs see format-preserved tokens instead of raw PII. Tool calls stay intact.
Intercept Outbound
Mask intercepts data leaving LLMs and decrypts it for downstream use.
Secure Execution
Tools execute with real data securely. End-to-end encryption maintained.
Benefits
Mask Advantages
Privacy that doesn't break your AI agents.
Industry-compliant Security
Agents reason over PII without seeing raw plaintext. Critical for finance and healthcare.
Consistent Tool Execution
Format-preserved encryption keeps model context and tool calls intact. No blind redactions.
Improved Speed
Privacy computation stays local, not hitting an API. Agents execute faster than competitors.
