The technology allows controlled bi-directional transfer of classified data between different networks and command levels, enabling forces to respond more quickly to evolving threats. Insta stated that the solution ensures operational security in data transmissions and applies NATO standards while incorporating advanced cybersecurity measures to filter and limit what information can be transmitted or received by different parties.
Developed in collaboration with Lockheed Martin, Insta DomainLink Secret is aimed at addressing the growing complexity of data exchange in NATO missions involving multiple participants and vast operational areas. By safeguarding sensitive information against cyber threats and ensuring its controlled flow, the solution enhances both situational awareness and tactical decision-making.
Petri Reiman, Senior Vice President, Defence and Cyber Security at Insta, highlighted the practical importance of real-time data exchange in joint operations. “For example, if there were a military conflict in Europe, it would be necessary to communicate critical information between different systems and chains of command. An F-35 on a stealth mission needs to be able to share the information that all of its sophisticated sensor systems detect with the rest of the forces. If the aircraft detects an enemy threat, you need to decide very quickly who responds to it: the air force, a navy vessel, or ground-based assets? Real-time sharing of data and its effects across all branches is critical for both command and on-field operatives to effectively respond to threats and achieve high joint operational capability,” he said.
Traditionally, different branches such as naval forces and air defence have operated their own command and control systems with limited interoperability. Without proper cybersecurity controls to enable secure connections, exchanging information has often been restricted, slowing decision-making and reducing situational awareness. This lack of integration could put missions and personnel at risk, particularly in fast-moving scenarios.
Until now, cross-domain technologies have typically required tailor-made programming or complex scripting. These solutions were slow to implement and limited by pre-defined rule sets that could not be altered during real-time operations. Insta DomainLink Secret™ seeks to overcome these constraints by allowing system operators themselves to adjust operational rules instantly, without the need for technical reprogramming. This flexibility is intended to improve responsiveness and efficiency in critical environments.
The new system also addresses the need to balance information superiority with operational security. While commanders and field operatives require access to mission-critical data from multiple sources, some information must remain restricted to avoid jeopardising operations. Insta DomainLink Secret provides filtering features that allow operators to define what data is transmitted, what can be received, and even control what specific systems, such as radar, are permitted to share.
“Information superiority is a key dimension of multi-domain operations – you simply must have a full operational picture available at all times. Our Cross Domain Solution has been specifically developed to meet the increasing challenges of the modern defence and military realities, including cyber threats. Our decades of experience in demanding defence solutions and strong focus on developing state-of-the-art command and control systems utilising data and AI put us in a unique position to offer secure solutions for NATO needs,” said Reiman.
Insta DomainLink Secret is based on Field Programmable Gate Array (FPGA) technology, which enables hardware-based content validation and filtering. This not only improves performance and resilience against threats but also provides adaptability, as the hardware can be reconfigured without removal to respond to changing operational requirements.
The launch coincides with growing investment in defence and cybersecurity. The last few years have seen a rise in cyberattacks against military systems, prompting governments to strengthen digital defences. The United Kingdom increased spending on cyber capabilities in 2025, and at the NATO Summit in The Hague the same year, member states committed to spend 5% of GDP on defence by 2035, including 1.5% dedicated to cybersecurity and critical infrastructure protection.
Insta also plays a role in Finland’s future air defence capabilities. From 2026, the country will begin receiving F-35 stealth fighters, considered the world’s most advanced combat aircraft. In addition to maintaining the avionics of the new fleet, Insta will integrate the F-35’s systems with Finnish command and control infrastructure in cooperation with the Finnish Defence Forces.
The company will present Insta DomainLink Secret at DSEI UK 2025, one of the world’s largest defence and security exhibitions, held in London from 9 to 12 September.
