Tines was built to support the world’s most important workflows, including the work of strengthening cyber resilience at every level. That’s why we were so excited and honored to participate in Defence Cyber Marvel 4 (DCM4), a global cyber defense exercise led by the British Army Cyber Association and hosted in Seoul, South Korea.
Organised by a dedicated volunteer team of military and civilian personnel, DCM4 is the largest defence-led cyber exercise of its kind.
The event brought together over 1,000 participants from 27 countries, including military personnel, government agencies, and industry partners - all collaborating to test, improve, and innovate cyber defence capabilities.
DCM4 uses a sophisticated cyber range to simulate real-world systems and networks, incorporating emerging technologies like AI and quantum computing to prepare for future threats. It's inspiring to see how this volunteer-run exercise continues to improve the cyber defense capabilities of the UK and its international partners.
Strength in partnership
For our first year at DCM4, Tines joined forces with Elastic and Endace to support the defending blue teams in this complex, simulated environment. Together, we enabled participants to rapidly deploy a resilient, self-hosted detection and response stack - combining Elastic’s SIEM, Endace’s packet capture, and Tines’ no-code automation platform.
Whether integrating with intelligence tooling or orchestrating actions across systems, our goal was to empower participants to act faster, with greater confidence and precision, even under the constraints of an air-gapped environment.
Speed, scale, and flexibility
In real-world incidents, the ability to move quickly and adapt is critical, and DCM4 was no different. Throughout the exercise, more than 50 self-hosted Tines tenants were spun up — many in a matter of hours. This speed of deployment, combined with the security and control offered by self-hosting, demonstrated why Tines is uniquely well-suited for these types of high-stakes missions.
Tines gave teams the ability to create and iterate workflows on the fly, helping defenders visualize, react to, and adapt to aggressive red team tactics.
Learning through collaboration
DCM4 isn’t just about testing processes, it’s about sharing knowledge and building skills. Participants took part in a wide range of challenges designed to simulate real-world cybersecurity incidents, from disruptive state-level attacks to full-spectrum national threats.
By involving technology partners like Tines, the organizers showcased how modern tools can be used not just to defend, but to teach, giving participants hands-on exposure to cutting-edge technology that will shape the future of defence cyber operations.
Looking ahead
We’re incredibly grateful to the Army Cyber Association for inviting Tines to join DCM4, and proud to stand alongside partners like Elastic and Endace in delivering mission-critical capability at speed.
Events like this not only highlight the importance of international collaboration - they also underscore how adaptable, self-hosted technologies like Tines can give defenders the speed and confidence they need, even in the most demanding environments.
