The AI control plane for PII redaction.
Route your AI agents’ LLM calls through Treza to strip sensitive data before it reaches any provider — with redaction policy, audit logs, and least-privilege access in one place.
One layer between your agents and the model
An AI control plane governs how your agents reach LLMs. Treza is the control plane for data privacy: a proxy that redacts PII, enforces policy, and audits every request — so you can run AI on sensitive data without leaking it.
from openai import OpenAI
client = OpenAI(
base_url="https://app.trezalabs.com/api/redact",
api_key="treza_...", # your Treza key
)
# PII is stripped before the prompt ever reaches the model
client.chat.completions.create(
model="gpt-4o",
messages=[{"role": "user", "content": "Email jane@acme.com re: invoice #4471"}],
)Agents leak data you can’t see
The moment an agent calls an LLM, sensitive data leaves your perimeter — usually with no policy, no redaction, and no record.
PII leaks to the model
Raw prompts ship names, emails, and SSNs straight to third-party LLM providers.
No audit trail
When an agent sends sensitive data, there's no record of what left your perimeter.
Over-privileged agents
Agents see far more sensitive data than the task in front of them requires.
Compliance exposure
GDPR, HIPAA, and SOC 2 reviews stall when data handling can't be proven.
Three steps to redacted AI
No SDK to learn and no agent to rewrite — just a base URL change.
Point your client at Treza
Swap your provider base URL for the Treza redaction proxy. Your existing SDK calls stay the same.
Treza redacts in flight
The proxy detects PII and replaces it with typed placeholders before forwarding to the model.
Model responds, you audit
The completion returns through Treza, every request is logged, and sensitive data never left your control.
Policy, redaction, and audit in one plane
Everything you need to put guardrails around how agents touch sensitive data.
Inline PII redaction
Detect and strip names, emails, SSNs, payment data, and more before any prompt reaches the model.
Per-proxy policy
Define exactly which entity types to redact for each use case, provider, and environment.
Full audit log
Every redacted request is logged and exportable — proof for security, legal, and auditors.
Least-privilege access
Scope what each agent and key can do so models only ever see the minimum required.
Usage metering
Track redaction requests per period with usage-based pricing and overage visibility.
Any provider
Works with OpenAI, Anthropic, Azure OpenAI, or a custom upstream — no agent rewrite.
