HP Introduces TPM Guard to Block Physical Attacks on Encrypted Data
Event summary
- HP launched TPM Guard, the first hardware solution to prevent physical TPM bus attacks that bypass BitLocker encryption.
- New HP Wolf Security capabilities integrate with Workforce Experience Platform to reduce operational overhead and cyber-risk.
- HP expanded quantum-resistant security to its LaserJet Pro 4000/4100 and Enterprise 5000/6000 printer series.
- TPM Guard will be available as a firmware update for select HP G2 commercial PCs starting July 2026 at no additional cost.
The big picture
HP's TPM Guard addresses a critical security gap in enterprise PCs, where physical access attacks can bypass BitLocker encryption. As hybrid work models expand and AI applications process more sensitive data, the need for robust hardware security solutions is growing. HP's move positions it as a leader in endpoint security, particularly for organizations handling highly sensitive information. The integration of quantum-resistant security in printers also reflects the company's forward-looking approach to emerging cyber threats.
