Dell and HP Roll Out Quantum-Resistant Device Security and AI-Era Cyber Resilience

HP and Dell Technologies separately announced new security capabilities this week that strengthen hardware-level protections and data resilience against physical attacks and emerging quantum-computing threats in the AI era.  HP launches TPM Guard and adds quantum-resistant cryptography to printers HP introduced hardware-based HP TPM Guard, which encrypts the link between the Trusted Platform Module and CPU to block physical bus-intercept attacks that can break full-disk encryption solutions such as Microsoft BitLocker.  “With this protection in place, all TPM responses – including full disk encryption keys – are sent through an authenticated and encrypted tunnel rather than travelling across the motherboard in cleartext. This makes physical bus sniffing attacks ineffective,” HP explained. “Beyond this, TPM Guard also protects against advanced TPM move and interposition attacks. During manufacturing, HP establishes a pre‑shared hardware key that binds the TPM to its specific CPU. This binding ensures that a TPM removed from its original device – or presented with replayed measurements – can’t be tricked into releasing its secrets,” it added. HP also announced new HP Wolf Security capabilities for commercial PCs, deepening integration with the Workforce Experience Platform (WXP). Enhancements include Wolf Controller/WXP integration to reduce risk and operational friction, a next-generation Wolf Connect cellular card offering improved accuracy with lower power consumption, and broader and lower-cost support for the Sure Recover platform. The company also added quantum-resistant cryptography to its new LaserJet Pro and Enterprise printer lines. In the Enterprise series printers, HP Wolf capabilities are designed to provide protection against cyberattacks, including zero-day attacks. In addition, the enterprise printers include a feature called Automated Guided Redaction, which detects and removes personal, financial, and other sensitive data.  Dell introduces quantum-resistant firmware signing and PowerProtect enhancements Dell revealed quantum-ready upgrades to its 2026 commercial PCs. Specifically, the company has introduced security features designed to harden the embedded controller (EC) and protect firmware with quantum-resistant code signing. “This helps prevent the controller from accepting malicious or tampered firmware and reduces supply chain risk by validating updates with stronger encryption and digital signatures,” Dell explained. In addition, the company upgraded BIOS tampering detections, improving resilience even against quantum-powered attacks. [ Read: Cyber Insights 2026: Quantum Computing ] Dell also announced enhancements to its PowerProtect cyber resilience products, including an AI assistant in PowerProtect Manager to help organizations respond more efficiently to recovery-related issues.  Cyber resilience has been extended to smaller environments with the new PowerProtect Data Domain DD3410 appliance, and an updated Data Domain Operating System now supports TLS 1.3 for stronger encryption of data in transit. To address visibility gaps in AI workloads, Dell is expanding its Managed Detection and Response (MDR) service to Dell PowerScale storage platforms, providing enhanced threat visibility into unstructured data and AI environments. Additionally, Dell introduced an EDR-only service option that monitors and responds to endpoint threats with advanced detection and next-generation antivirus. When paired with Dell PCs, it provides BIOS verification insights and automatically alerts Dell’s MDR team if a potential BIOS compromise is detected.
