The Compliance Gap

Your secrets are leaving the browser.

Every day, employees paste client names, API keys and internal code into ChatGPT. Most don't think twice about it.

Without rehydra

The "Shadow AI" Risk

Employees paste sensitive data into public models.
API keys and credentials are accidentally sent to LLMs.
Security teams have no logs of what data is leaving the VPC.
IT blocks ChatGPT entirely.

Meet rehydra

The Privacy Shield for GenAI.

rehydra sits between your browser and the LLM provider. We anonymize PII in real-time, in your browser, allowing your team to use AI freely without sensitive data ever leaving your device.

Semantic Anonymization

We don't just blur text. We swap sensitive entities (Names, API Keys, Bank information) with context-aware placeholders, preserving the AI's ability to reason while hiding the secrets.

Rehydra anonymizes and rehydrates conten.

Full Observability

Gain a centralized view of which security risks we mitigated in your organization. Deploy our Docker container in your cloud to keep audit logs and encryption keys strictly internal.

Flexible Deployment

One platform. Three ways to stay safe.

Whether you are a solo developer trying to move fast, a CISO securing a thousand seats or just want to stay safe using ChatGPT, rehydra fits your workflow.
