The pipeline

Four checkpoints between your users and the model.

01

Intercept

Drop-in SDK or proxy sits in front of OpenAI, Anthropic, Bedrock, or your own model gateway.

02

Inspect

Every prompt, tool call, and response is scored against your policies in under 8ms.

03

Enforce

Block, redact, or rewrite in real time. Or just observe — you stay in control.

04

Audit

Immutable, cryptographically signed logs your auditors can verify themselves.

Platform

Built for teams shipping AI to regulated industries.

Read the technical overview

Real-time policy engine

Write policies in plain language or YAML. Hot-reload across every environment without a deploy.

PII & secrets redaction

60+ detectors for PHI, PCI, API keys, and custom patterns. Reversible tokens when you need them back.

Prompt-injection defense

Detect jailbreaks, indirect injections, and tool-use exfiltration with a model trained on 4M attack samples.

Immutable audit trail

Every call signed and chained. Export to S3, Snowflake, or your SIEM in the format auditors expect.

8ms p50 overhead

Edge-deployed inspectors run beside your model, not in a round-trip across the country.

Works with any model

OpenAI, Anthropic, Google, Bedrock, Mistral, Llama, and your fine-tunes. One API, one dashboard.

Compliance

Every framework your auditor will ask about.

Zaprex ships with mapped controls and evidence collection for the frameworks that matter most. One source of truth, every audit.
