HP Inc. (NYSE: HPQ) announced the launch of HP TPM Guard, a hardware solution designed to prevent physical attacks that can bypass BitLocker drive encryption. The technology was unveiled at HP Imagine 2026 on March 24, 2026.

HP TPM Guard addresses vulnerabilities in Trusted Platform Module (TPM) bus communications that allow attackers with physical access to devices to intercept data between the TPM chip and CPU. According to the company, these attacks can be performed in under a minute using approximately $20 worth of hardware.

The solution creates an encrypted link between the TPM and CPU and cryptographically binds the TPM to the device, making it inoperable if removed or tampered with. HP states this represents the first hardware solution to address TPM bus attacks in business notebooks.

"PCs already hold huge amounts of sensitive information, and new multi-media AI applications are pushing more sensitive workloads to the edge," said Dr. Ian Pratt, VP, Security & Commercial Systems CTO, Personal Systems at HP. "Today an attacker with a couple of hours of training and a $20 hardware kit can bypass that protection."

HP TPM Guard will be available from July 2026 on select HP G2 commercial PCs as a firmware update, with no additional cost to customers. The company has submitted a proposal to the Trusted Computing Group to contribute the technology as an industry standard.

HP also announced enhancements to its Wolf Security capabilities and introduced new LaserJet printer series featuring quantum-resistant cryptography. The LaserJet Pro 4000/4100 Series and LaserJet Enterprise 5000/6000 Series include protection against potential quantum computer-based attacks.
