The Compliance Gap
Your secrets are leaving the browser.
Employees are pasting sensitive code and customer PII into ChatGPT every day. You shouldn't have to choose between productivity and privacy.
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 VPC.
Semantic Anonymization
We don't just blur text. We swap sensitive entities (Names, API Keys, CC#) with context-aware placeholders, preserving the AI's ability to reason while hiding the secrets.
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.
Pricing & Plans
Enterprise-grade privacy. Zero-knowledge architecture.
