As concerns grow around how artificial intelligence platforms handle sensitive data, privacy focused companies are introducing new approaches to ensure user information remains protected during AI interactions.
ExpressVPN has launched ExpressAI, a private AI platform designed to deliver AI capabilities without exposing user data to profiling or model training. The ExpressVPN private AI platform leverages confidential computing to process user interactions in secure, isolated environments, marking a significant step toward privacy first AI adoption.
At the core of ExpressAI is the use of secure enclaves, which allow decrypted conversations to be processed within cryptographically isolated environments. According to ExpressVPN, this ensures that user data remains inaccessible not only to external infrastructure but also to the company itself. The system is built on a zero knowledge architecture combined with end to end encryption, meaning only the user can decrypt stored conversations and files.
The ExpressVPN private AI platform also introduces features aimed at giving users greater control over their data. Conversations are not retained for model training, and users can enable a ghost mode that automatically deletes chat history. Additionally, the platform includes an encrypted vault protected by a user defined password, ensuring that stored data cannot be accessed without the correct credentials.
At launch, ExpressAI supports multiple AI models from providers such as OpenAI, DeepSeek, Alibaba through its Qwen models, and NVIDIA. The platform allows users to compare responses across different models side by side, offering flexibility for tasks ranging from writing and coding to document analysis and technical problem solving.
To validate its security claims, ExpressVPN engaged Cure53 to conduct an independent audit. The assessment included penetration testing and a review of the platform’s code, cryptography, and infrastructure. According to ExpressVPN, all identified vulnerabilities were addressed prior to launch.
“Cure53 concludes that the product meets its stated privacy objectives by providing modern AI capabilities within confidential computing enclaves, where user interactions are processed in cryptographically isolated contexts.”
The launch reflects a broader industry shift as users increasingly rely on AI for sensitive tasks such as financial planning, healthcare inquiries, and personal decision making. Many existing AI platforms store or analyze user inputs, creating concerns around data exposure and misuse.
“With ExpressAI, ExpressVPN is effectively extending its long-held stance on traffic protection to AI interactions: The best way to protect user data is not to collect it in the first place,” said Shay Peretz, chief operating officer at ExpressVPN. “We’re not just making privacy claims – we’re proving it with cryptographic guarantees. With our enclave architecture, your messages exist in a secure, isolated environment that even we can’t access. This is the future of reliable, private AI.”
Peretz added, “People are already turning to AI for high-stakes, personal conversations – from health questions to financial decisions. Whether you’re accessing a bank account online or discussing private matters with a professional, you expect strong privacy protections. But those protections don’t automatically carry over to everyday AI chats. That gap has left many users uneasy about how their data is handled. ExpressAI was built to remove that fear and show that private, trustworthy AI can be part of the tools people use every day.”
The ExpressVPN private AI platform signals a growing emphasis on privacy preserving AI, where secure computation and encryption are central to user trust. As AI adoption continues to expand, solutions that balance usability with strong data protection are expected to play a key role in shaping the future of consumer AI services.
