New Highlights
- HP introduces the first hardware solution to block physical TPM bus attacks, closing a known security gap in BitLocker.
- HP strengthens PC security with new features in HP Wolf Security.
- HP unveils a new LaserJet lineup with quantum-resistant security.
On March 24, 2026, at HP Imagine in New York, HP launched HP TPM Guard, the first hardware solution created to stop physical TPM bus attacks. This enables business notebooks to prevent physical access attacks that could bypass BitLocker drive encryption. HP also announced updates to its HP Wolf Security PC lineup and expanded quantum-resistant security to more HP printers.
Closing the BitLocker Security Gap With HP TPM Guard
PCs play a central role in today’s hybrid work environments, storing large amounts of sensitive information, including confidential documents, credentials, and customer or employee data. As AI applications process more voice, video, and screenshots, the amount of sensitive data on PCs continues to grow.
Many businesses rely on BitLocker to encrypt data if a PC is stolen or lost. However, recently discovered vulnerabilities allow attackers with physical access to bypass BitLocker protection using TPM bus attacks. These attacks tap into the communication channel between the Trusted Platform Module (TPM) and the CPU, intercepting encryption keys or sensitive data. Attackers can execute this in under a minute using inexpensive tools and minimal training.
HP TPM Guard addresses this threat by establishing an encrypted connection between the TPM and CPU, preventing interception and probing attacks. The TPM is securely tied to the device, so it will not work if removed or tampered with. This closes a major security gap without complicating IT teams’ work.
Dr. Ian Pratt, VP, Security and Communications Systems, CTO, Personal Systems, HP Inc., said PCs already hold huge amounts of sensitive information, and new multimedia AI applications are pushing more sensitive workloads to the edge. The security of the underlying PC platform is increasingly critical to the future of work. While BitLocker has previously been relied upon to protect data, today, an attacker with a couple of hours of training and a $20 hardware kit can bypass that protection.
Dr. Ian Pratt said HP, together with silicon partners, developed hardware and firmware to prevent these attacks, delivering the stronger protection customers expect. He stated this solution addresses an industry-wide issue relevant for all organizations handling sensitive data.
HP TPM Guard is the newest security innovation from HP Security Lab, which has been developing solutions for over 20 years. HP now works to spot new threats, build solutions for its products, and work with industry groups to improve security standards. HP has already proposed making TPM Guard technology an industry standard through the Trusted Computing Group.

New HP Wolf Security Capabilities To Reduce Cost And Risk For Businesses
HP is also enhancing security on its commercial PCs by introducing new features to HP Wolf Security, designed to connect the Workforce Experience Platform (WXP), HP Wolf Security, and Enterprise Systems more effectively. These updates aim to simplify management, reduce operational costs, and lower cybersecurity risks. The new features include the following.
- Wolf controller/WXP integration to reduce risk and operational friction.
- The next-generation Wolf Connect cellular card offers improved tracking accuracy while consuming less power.
- Support for a broader range of devices on the Sure Recover platform is now available at a reduced cost.
- Centralized security log collection is now managed through the Wolf controller, streamlining security oversight.
Quantum Resistance: The Future Of Print Security
Experts estimate up to a 34% chance that quantum computers could break current public-key encryption methods by 2034. This threat increases the urgency for cryptography that can withstand quantum attacks. Printers are frequently targeted as entry points to networks. So, HP is implementing quantum-resistant cryptographic algorithms in more devices to secure documents and network access.
- The new HP LaserJet Pro 4000–4100 series are the first SMB printers to offer quantum-resistant protection, as well as tamper-resistant toner chips, firmware, and packaging. The HP Force Experience Platform and optional HP Security Manager help make security compliance and device management easier across all devices.
- The new HP LaserJet Enterprise 5000-6000 series is the first enterprise printer to feature built-in protection against quantum computer-based attacks, reducing the risk of data exposure. These printers use HP Wolf Enterprise to detect, isolate, and automatically recover from cyberattacks and are the only printers with zero-day threat identification and recovery during memory code execution.
The HP LaserJet Enterprise 6000-6000 series will also offer automated guided redaction, which identifies and removes sensitive information such as personal or financial data. This helps organizations meet compliance requirements without adding extra work to IT teams.
