How to Choose

Why TPM Matters: Research and Evidence

Independent guidance and vendor research support using hardware roots of trust to reduce security risk across enterprise endpoints. Standards bodies and major platform vendors recommend TPM and secure boot as part of a layered defense strategy because hardware-backed keys and measured boot reduce the attack surface for credential theft and persistent firmware attacks. For organizations in the USA, adopting TPM-enabled desktops is a practical step toward meeting regulatory expectations and improving resilience against common enterprise threats.

NIST and industry guidance recommend hardware roots of trust and secure boot mechanisms to strengthen endpoint security and integrity.

TPM stores cryptographic keys in isolated hardware, making it considerably more difficult for attackers to extract credentials compared with software-only storage.

Integration with full-disk encryption solutions such as BitLocker provides seamless protection for data at rest and helps meet compliance requirements.

Measured and secure boot reduce the risk of persistent malware by ensuring only trusted firmware and OS components load during startup.

Vendor whitepapers and enterprise case studies show TPM adds strong security with minimal performance impact for typical office workloads.
