Cybersecurity innovations tailored for defence tech

21st century conflict, digitalised and all-pervasive, is not limited to specialised military infrastructure and solutions.

Leveraging deep experience with defence forces, we tailor modern technologies and battle-earned insights to make mission-critical systems secure, ensuring they remain resilient under real-world pressure.

Enabling secure modern defence technology capabilities

Mission-aligned security

Security and resilience in defence systems demand solutions that perform under pressure and fatigue of users. We engineer security measures tailored to operational realities, ensuring mission continuity and success.

Security that adapts under fire

Security is a constant competition. Advanced adversaries operate with well-planned strategies and near-unlimited resources, changing their tactics, techniques and procedures. Only well-designed and thoughtful security can adapt to evolving tactics and recover quickly from incidents.

Security for advancing defence tech

Modern warfare increasingly relies on commercial and non-military tech, widening the attack surface. Security must keep pace with evolving defence tech and meet new operational realities. We build defences that blend proactive and reactive measures, tailored to real-world threats.

Novel security for novel tech capabilities

New battlefield technologies need security beyond traditional “military-grade”. We rely on strong fundamental security, cryptography, defence in depth, data-centric security architecture and zero trust principles to ensure new capabilities are resilient, secure by design, and ready for mission.

Cossack Labs advantages

Battlefield experience

Battle-hardened experience through years of helping critical Ukrainian defence systems stay secure and operational. Not just “battle-tested”, but actively used and relied on, every day, by agencies, branches and forces.

Securing nation-scale and planet-scale systems

Our team brings experience from protecting military systems, OT / industrial control systems, finance, healthcare that are exposed to elevated risks daily, and stay serving millions of people despite advanced threats.

Advanced R&D lab

We solve high-risk, mission-critical problems by adapting cutting-edge R&D to defence and critical civilian environments whatever it takes – designing new hardware, protocols, figuring out complex security problems as they emerge in practice.
