New York, Mar 27: HP Inc. today announced a major advancement in hardware security with the launch of HP TPM Guard at HP Imagine 2026, marking the world’s first business notebook solution designed to prevent physical-access attacks that can bypass BitLocker drive encryption.
As hybrid work environments expand and AI-driven applications increase the volume of sensitive data stored on devices, securing endpoints has become more critical than ever. HP TPM Guard addresses a key vulnerability known as TPM bus attacks, where attackers intercept communication between the Trusted Platform Module (TPM) and CPU to extract encrypted data.
Closing Critical Security Gaps
HP TPM Guard introduces an encrypted communication link between the TPM and CPU, effectively preventing interception and probing attacks. The solution cryptographically binds the TPM to the device, ensuring it becomes inoperable if tampered with or removed—closing a longstanding industry-wide security gap without adding complexity for IT teams.
Commenting on the launch, Dr. Ian Pratt, VP, Security & Commercial Systems CTO at HP Inc., said:
“PCs already hold vast amounts of sensitive information, and AI applications are accelerating this trend. While BitLocker has been widely relied upon, emerging attack techniques have exposed vulnerabilities. HP TPM Guard delivers a hardware and firmware solution that eliminates this entire class of threats.”
HP has also submitted the TPM Guard technology proposal to the Trusted Computing Group, aiming to elevate industry-wide security standards.
Enhanced HP Wolf Security Capabilities
In addition to TPM Guard, HP announced new enhancements to its HP Wolf Security portfolio, focused on reducing operational risk and improving enterprise security management. Key updates include:
- Integration of Wolf Controller with Workforce Experience Platform (WXP)
- Next-generation Wolf Connect cellular card for improved efficiency
- Expanded Sure Recover platform support at reduced cost
- Centralized security log collection for streamlined monitoring
Advancing Toward Quantum-Resistant Security
Recognizing the growing threat posed by quantum computing, HP is expanding quantum-resistant cryptography across its printer lineup.
New offerings include:
- HP LaserJet Pro 4000/4100 Series – the world’s first SMB printers with quantum-resistant protection
- HP LaserJet Enterprise 5000/6000 Series – enterprise printers designed to withstand quantum-based attacks, featuring zero-day threat detection and automated recovery
These devices are powered by HP Wolf Enterprise and include features such as automated guided redaction to enhance data privacy and compliance.
