HP and Karamba Security Sign Multi-Year Licensing Agreement to Protect Millions of HP’s Printers
The companies extend their longstanding agreement with a three-year renewal for XGuard® runtime integrity software, strengthening HP Print security leadership
Palo Alto, California and Hod Hasharon, Israel – February 3rd, 2026 — HP (NYSE: HPQ), the world’s largest printer provider, and Karamba Security, a global leader in product cybersecurity, announced today that HP has renewed its multi‑year agreement to license Karamba’s XGuard® software across HP’s business printer families. The renewal marks years of collaboration, strengthening HP’s commitment to deliver the world’s most secure printers.
Printers: The Back Door to the Enterprise
Modern printers have evolved into fully networked, cloud-connected, computing devices with powerful processors and remote‑management capabilities. As a result, they have become prime targets for attackers. Hackers attempt to exploit vulnerabilities in printer firmware, extract sensitive data from it, and use it as a segway into the organizational network.
HP’s Industry-Leading Security Strategy
HP provides the “world’s most secure printers”, embedding multiple layers of hardware- and firmware-level defenses. HP’s adoption of Karamba’s XGuard forms a critical part of this architecture.
“Security remains a top priority for HP as our customers face increasingly sophisticated adversaries,” said Shivaun Albright, Chief Technologist for Print Security at HP Inc. “Karamba Security’s XGuard software delivers reliable runtime protection, helping our customers safeguard their printers against a broad range of cyberattacks, such as file-based and file-less malware.”
How XGuard Protects HP Printers
Karamba’s patented XGuard® technology enforces binary-level allow-listing and Control Flow Integrity directly inside the printer firmware. It provides protection by:
- Blocking unauthorized code execution through deterministic allow‑listing
- Preventing memory‑manipulation attacks such as buffer overflows
- Preserving runtime integrity to prevent exploitations of zero‑day or known vulnerabilities
A Six-Year Strategic Partnership
Since 2020, Karamba and HP have collaborated to integrate XGuard across multiple generations of HP’s printers to offer HP users unmatched security levels.
“We are proud to partner with a formidable and global leader such as HP Print”, said David Barzilai, Co-Founder and CEO of Karamba Security. “This agreement strengthens our long-term partnership with HP and reinforces the industry’s move toward a simple to integrate - yet broadly defensive - product security”.
“Our collaboration with Karamba Security has proven highly valuable”, continued Shivaun Albright. “XGuard software was seamlessly integrated into our printers, enabling HP to continue delivering the world’s most secure printers, as it has done for over a decade.”
