ExpressAI is built on confidential computing enclaves. These are secure, isolated environments that process your data with end-to-end encryption. This means your prompts, files, and conversations can never be accessed by others and never be used for training.
Confidential computing is a hardware-based security technology that creates a sealed execution environment called an enclave. Only the enclave can access the data being processed, preventing cloud providers, attackers, or even ExpressVPN employees from viewing it.
Most AI services store some portion of prompts or conversations on their servers and may use them for training or quality improvement. ExpressAI ensures all information is end-to-end encrypted and never used to train models. Every interaction happens inside verifiable, encrypted enclaves that even ExpressVPN cannot access.
Beyond our secure backend architecture, ExpressAI gives you direct control over your privacy with built-in tools:
- Zero-access chat history: Saved chats and uploaded files are secured with a user-generated primary password that ExpressVPN cannot see or reset.
- Ghost mode: Users can configure conversations to automatically expire and delete themselves.
- Private web search: The AI can fetch real-time internet data without compromising your identity or exposing your queries to trackers.
ExpressAI has been independently audited by Cure53, a leading cybersecurity firm known for its rigorous security assessments. You can read the full audit report here.
