The GenAI Security Standard

Using Cloud LLMs means exposing data to external services. PromptGuard prevents leaks automatically — scanning every prompt locally before it ever leaves your system.
Home icon

100% Local Processing

All scanning, blocking and logging happens locally on your network. No data sent to external servers. No telemetry. Complete Privacy.

Link icon

Universal Compatibility

Works with any OpenAI-compatible endpoint - ChatGPT, Claude, Cursor, Copilot, local models and more. Install once, protect everything.

Target icon

Intelligent Detection

Proprietary detection engine combines AI models, NLP, and pattern matching to identify thousands of sensitive data types in context. Catches what basic pattern matching misses.

Activity monitor icon

Complete Visibility

See exactly what was blocked, when, and in which prompt. Real-time transparency into every protection event.

Check verified icon

Built-In Compliance

Pre-configured policies for GDPR, HIPAA, SOX, SOC 2, ISO 27001, CCPA, and PCI-DSS. Automatic audit logs for compliance reporting.
