# SEV Technology ### What is Secure Encryption Virtualization (SEV) ? SEV technologies (including SEV, SEV-ES and moving towards SEV-SNP) address the cloud trust problem and bring world-class data security to it. It provides better security isolation, rooted in the hardware itself, that means customer data is protected cryptographically from each other and protected from the hosting software. Our ‘DNA Vaults’ harness SEV technology. These DNA Vaults are fully virtualized machines that run all processes in encrypted memory, encrypting user provided genomic data in storage with private keys provided by their mobile device. These user keys are never stored outside encrypted memory and are only available to the user.
