Intel Virtualization Technology for Directed I/O (VT-d) continues from the existing support for IA-32 (VT-x) and Itanium processor (VT-i) virtualization, adding new support for I/O-device virtualization. Intel VT-d can help end users improve the security and reliability of systems and also enhance the performance of I/O devices in virtualized environments. Intel Management Engine Firmware (Intel ME FW) uses built-in platform capabilities and management and security applications to remotely manage networked computing assets out-of-band. Intel Virtualization Technology (VT-x) allows one hardware platform to function as multiple “virtual” platforms. It offers improved manageability by limiting downtime and maintaining productivity by isolating computing activities into separate partitions. Intel Platform Trust Technology (Intel PTT) is a platform functionality for credential storage and key management used by Windows 8 and Windows 10. Intel PTT supports BitLocker for hard drive encryption and meets all Microsoft requirements for firmware Trusted Platform Module (fTPM) 2.0.
