Shipping since 2003, INTEGRITY Multivisor is built upon security-certified separation kernel technology that provides highly assured isolation between one or more "guest" operating systems (personas) while also providing a native open standard execution environment for security-critical tasks, including FIPS 140-2-certified and NSA Suite B-compliant data encryption, user authentication, security event auditing, and remote management. INTEGRITY Multivisor offers several approaches to virtualization, including paravirtualization and full virtualization with or without hardware hypervisor acceleration. As the digital world grows in complexity, no single operating system suffices. The hypervisor provides the right level of abstraction — the virtual machine — for flexibility, scalability, and portability, enabling elegant yet practical solutions to previously intractable computing problems..
