By TigerByte Cyber, a defense-focused cybersecurity company specializing in hardware-based edge computing solutions, announced on September 17 it has raised a $3 million seed funding round led by Hale Capital Partners with the participation of Tenon VC. The funding will support rapid scaling of TigerByte Cyber’s technology to modernize legacy communications and navigation systems across military and commercial aircraft, satellites, vehicles and drones.
The company’s solutions provide post-quantum encryption, policy enforced data validation, and system hardening techniques to defend these critical systems against cyberattacks. TigerByte Cyber’s technology has drawn strong interest from multiple U.S. government agencies, including the US Space Force, the US Navy and DARPA, and the company has secured over $7 million in contracts.
“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 Sage Secilmis, CEO of TigerByte Cyber. “By combining multiple DARPA-developed technologies, such as post-quantum encryption, data validation, and formal parsing, we are creating a new foundation for autonomous, resilient systems that can operate with complete confidence, maintain data integrity, and remain secure without disruption.”
Aircraft, satellites and other platforms increasingly rely on connected edge devices to enhance their capabilities, but many of these platforms were not designed to withstand today’s cyber threats. Recent incidents illustrate the risk: in August 2026, cameras aboard British Royal Navy K3 Scout unmanned surface vessels were found transmitting automated status signals to an internet address in China, and a Delta airlines passenger demonstrated how easily a spoofed in-flight Wi-Fi network could be created to intercept or manipulate connected traffic. These events show how threats can enter through trusted devices, third-party components, wireless networks and insider activity, as well as conventional external attacks. Strengthening the cybersecurity of these systems is essential to achieving trusted mission autonomy, preserving data integrity, and enabling aircraft and satellites to operate securely and without disruption.
TigerByte Cyber’s flagship product, Cyber Protection Suite (CPS), brings modern cybersecurity capabilities to legacy platforms. Designed for mission-critical edge environments, CPS combines an ultra-compact form factor with plug-and-play functionality. It delivers high-speed, hardware-enforced security, including policy enforced data validation, deep packet inspection, post-quantum encryption, and network segmentation. Its compact, resilient design enables in-transit encryption and deep packet inspection on aircraft, satellites and other space- and power-constrained environments.
TigerByte Cyber’s CPS technology has been validated through real-world testing with multiple government agencies. In March 2026, it achieved flight heritage by successfully upgrading the communications security of an operational satellite in orbit through the deployment of its encryption technology. In August 2026, TigerByte demonstrated its capabilities at the Navy’s Joint Interagency Field Experiment (JIFX) at Camp Roberts. The company was recently awarded a contract by the U.S. Space Force to investigate new approaches to edge computing in space, in addition to other government contracts totaling $7 million.
“Protecting data at the network edge is vital to ensuring the continued relevance and impact of legacy platforms as AI/ML continues to develop and connected devices and sensors proliferate,” said Nathan Foos, managing director at Hale Capital Partners. “TigerByte Cyber is solving an urgent and surprisingly hard problem that spans national security, commercial aviation and much more.”
