We help defence systems survive attacks and adapt in real time — whether we're hardening what you already run or engineering it from the ground up.
Trusted where failure is not an option
Ten years across IT, OT, and defence systems — including security solutions operating in Ukraine's power grid since the systemic attacks of 2016–2017, and through the sustained cyber-physical attacks since 2022; and architecting, building, and securing integrated targeting, situational-awareness, and force-level C2 systems used in active conflict.
We work on defence systems alongside the operators who run them and the vendors who build them, from system design through to field deployment, with dozens of projects spanning Ukrainian and international defence and dual-use manufacturers.
UA DroneIDUA DroneID is a security and identification technology for unmanned systems that must operate in contested, degraded, and adversarial network conditions. As cybersecurity partner on the programme, we shaped the standard, security, and reference implementation for integration of unmanned systems into control and coordination system.
Ukraine’s primary C2 system operates under daily nation-state-level cyberattacks. Cossack Labs works with the DELTA team as a security engineering partner: helping build and maintain a product security programme, as well as hardening more than 30 integrated systems so that the ecosystem remains operational, secure, and resilient under continuous adversarial pressure.
MINISTRY OF DEFENCE OF UKRAINEThe programme that let the Ministry of Defence of Ukraine assess and mitigate the risks across its defence information and communication systems. Grounded in first-hand understanding of how adversaries operate against defence systems in active conflict.
Over 1 million active-duty military personnel rely on the platform's digital services, developed by the Ministry of Defence of Ukraine. The platform runs dozens of business integrations – each a potential threat vector. We work with the Army+ team on the platform's product security programme to design and implement a multi-layered security system that reduces the risks of data compromise and enables the security of integrations.
What our partners say
The security engineering team cares not only about security but also about the product itself. It creates real alignment, making security feel like a natural part of the process rather than just a compliance checkbox.

Identify weaknesses across legacy and modern systems — hardware, software, and the interfaces between them — before an adversary does, so your teams keep operational tempo without disruption.
Learn moreWe work alongside defence agencies and public-sector organisations to navigate complex security challenges — supporting decisions and shaping policy, grounded in deep technical understanding.
Learn moreBring defence products and emerging capabilities to field deployment with confidence they will hold under adversarial conditions — from architecture review through to live-environment deployment.
Learn moreWhen existing standards don't cover the problem, we build what's missing: new protocols, security controls, and methodological frameworks. We assess emerging capabilities for the weaknesses standards haven't yet caught up to.
Learn moreCross-domain integration framework
for mission-critical systems
Interoperability framework for heterogeneous distributed systems, enforcing security across untrusted networks, and delivering data to control and decision systems under degraded, intermittent or denied connectivity.
Proven in the most challenging environments, operating across private, national and defence critical infrastructures, under daily real-world attacks.
Security and lifecycle management
for edge device fleets
Platform for building and operating secure fleets of edge devices across their full lifecycle, in contested, disconnected environments.
Proven in the most challenging environments: application spans the private and public sectors, including power grids and defence, under daily real-world attacks.
Securing AI from model build
to field inference
Securing AI across its lifecycle — datasets, training environments, models in the cloud and at the edge, and the AI-enabled applications. Built for ML models running in high-risk environments, shaped by real threats and operational requirements.
Helmet capabilities are built and running across our programmes in private and public sectors including mobile apps with 100 million+ users and defence systems.
