TigerByte Cyber has emerged from stealth mode with $3 million in seed funding led by Hale Capital Partners, with additional backing from Tenon VC. The Hanover, New Hampshire based company focuses on cyber hardening for AI and edge devices, aiming to secure systems at the point where they physically operate rather than relying solely on network-level defenses.

Bringing Modern Protections to Legacy Systems

The company’s flagship product, Cyber Protection Suite (CPS), is described as an ultra-compact, plug-and-play solution that delivers hardware-enforced security capabilities. These include data validation, deep packet inspection, network segmentation, and post-quantum encryption, all packaged for deployment on mission-critical edge devices that often run outdated or unpatched software.

According to the source material, TigerByte Cyber’s technology appears to build on work originally developed by WebSensing, a company founded in 2016 that specialized in single-chip network security products. Both products and personnel appear to have transitioned to the new TigerByte Cyber branding.

Government Contracts and Expansion Plans

TigerByte Cyber has already secured more than $7 million in contracts with US government agencies, including the US Space Force, the US Navy, and DARPA. The new seed funding will be used to scale the company’s technology for modernizing communication and navigation systems across military and commercial aircraft, drones, satellites, and vehicles. The company also plans to expand its manufacturing capabilities within the United States.

Why It Matters

CEO Sage Secilmis said the company was founded to bring cloud-style security principles to edge environments, where mission-critical systems often operate with limited protection and no tolerance for failure. Secilmis noted that combining DARPA-developed technologies such as post-quantum encryption, data validation, and formal parsing is intended to create a foundation for autonomous, resilient systems that maintain data integrity without disruption.

For security teams managing legacy operational technology, edge computing, or defense-adjacent infrastructure, TigerByte Cyber’s approach highlights a growing market push to retrofit hardware-level protections onto systems that were never designed with modern threat models, or quantum-era cryptography, in mind.
