PXI is the industry-leading platform used by engineers to build high-performance, mixed-measurement systems for validation and production test. These systems are used in many applications where security is a critical necessity.
Some PXI controllers include a Trusted Platform Module (TPM) chip. This can be used by the operating system to store encrypted information that can be used to protect the PC in various ways. It can be used to detect malicious software during the boot process, access the encrypted drive of a computer, improve network authentication, improve VPN protection, and more.
TPM provides secure storage for authentication artifacts used by the operating system. However, the OS software must use the TPM chip for it to be valuable to the security of the system. Windows 10 and Windows 11 use TPM, so a PXI controller with TPM will be more secure when running Windows.
NI Linux Real-Time does not yet use TPM, but NI engineering teams are exploring ways to make test systems more secure when running NI Linux Real-Time on the PXI system.
There are two versions of TPM used, 1.2 and 2.0. 2.0 has become common and is the most widely supported version in NI's PXI controllers.

CompactRIO modules do not currently contain TPM chips. NI engineers are working to add TPM to these devices. However, TPM can be provided in CompactRIO on a limited basis. Contact security@ni.com for more information.
