TigerByte Cyber exits stealth with $3M seed and $7M in government contracts
What's the deal? TigerByte CyberDealroom has a profile for this one. Try Dealroom →, a defence-focused cybersecurity startup, has emerged from stealth with a $3 million seed round led by Hale Capital PartnersDealroom has a profile for this one. Try Dealroom →, with Tenon VC participating. The company has also secured more than $7 million in contracts from US government agencies, including the US Space Force, the US Navy, and DARPA.
What's the endgame? TigerByte secures the edge devices that connect legacy aircraft, satellites, and communications systems to modern capabilities. Its flagship Cyber Protection Suite (CPS) delivers post-quantum encryption, policy-enforced data validation, deep packet inspection, and network segmentation in a compact, plug-and-play form built for space- and power-constrained platforms.
Why now? Recent incidents underline the risk. In August 2026, cameras aboard British Royal Navy K3 Scout unmanned surface vessels were found transmitting status signals to an internet address in China, and a Delta passenger showed how easily a spoofed in-flight Wi-Fi network could intercept connected traffic.
What's the traction? TigerByte's technology has been tested in real deployments. In March 2026, CPS upgraded the encryption of an operational satellite in orbit; in August 2026, the company demonstrated at the Navy's Joint Interagency Field Experiment at Camp Roberts. The Space Force recently awarded it a contract to explore new approaches to edge computing in space.
In their words: "We founded TigerByte Cyber to bring the principles of modern cloud security to the edge, where mission critical systems operate with limited protection and no margin for failure," said chief executive officer Sage Secilmis.
The signal: The round reflects growing demand to defend ageing military and commercial platforms — aircraft, satellites, vehicles, and drones — that were never built for today's threats. As these systems add connectivity, hardware-based security at the edge is becoming a distinct market pulling both venture and defence-agency money.
