Zero-Trust PII Masking and Data Privacy Vault for Enterprise LLMs & Agents

Adopting generative AI and autonomous agents in regulated sectors—such as banking, insurance, healthcare, and telecommunications—demands rigorous compliance with privacy mandates (GDPR, KVKK, HIPAA, and SOC 2).

Sending unredacted customer data to third-party model providers violates data residency and confidentiality requirements.

Bidirectional Tokenization: How Privacy Vault Works

Traditional masking tools permanently alter text, breaking the model's ability to reason over entities. Argate solves this with Bidirectional In-Memory Tokenization:

1. Ingress Redaction: As a user or agent submits a prompt, Argate identifies sensitive entities (SSN, credit cards, IBANs, email addresses, phone numbers) in <0.35ms.
2. Surrogate Token Injection: Replaces raw values with reversible cryptographic tokens ([REDACTED_SSN_1], [REDACTED_CARD_1]).
3. Safe Inference: The LLM receives only sanitized tokens. No raw PII is ever recorded in model logs or training pipelines.
4. Egress Detokenization: When the LLM responds or invokes an internal enterprise tool, Argate restores original values in volatile memory for the downstream tool execution.

Performance & Latency Benchmark

By executing entirely in volatile memory with zero disk I/O, Argate delivers enterprise compliance without sacrificing agent execution speed.
