The INTEGRITY architectures provides support for multiple Protected Virtual Address Spaces, each of which can contain multiple application tasks. The INTEGRITY kernel is itself protected in its own address space, along with kernel mode tasks.

The INTEGRITY® operating system technology is the most secure technology in the world having been certified by the NSA-managed NIAP lab to EAL6+ High Robustness. No other commercial operating system has attained his level of security.

The INTEGRITY RTOS is designed for use in embedded systems that require maximum reliability and absolute security. INTEGRITY represents the most advanced RTOS technology on the market today.

Without the burden of compatibility with 1980s vintage products, INTEGRITY was designed from the ground up. It employs the latest in RTOS technology and achieves unprecedented levels of reliability, availability, and security for a broad range of real-time applications.

INTEGRITY uses hardware memory protection to isolate and protect itself and user tasks from incorrect operation caused by accidental errors or malicious tampering. Its object-oriented design allows strict access control and verification of the security and integrity of data, communications, individual components, and the system as a whole. Its strict adherence to provable resource requirements allows an embedded system designer to guarantee resource availability. Unlike other memory protected operating systems, INTEGRITY does not sacrifice real-time performance for security and protection. It is first and foremost a true hard real-time operating system.
