Elastic on Defence Cyber Marvel 2026: A Technical overview from the Exercise Floor

Elastic served as a core technology partner for Defence Cyber Marvel 2026 (DCM26), the UK Ministry of Defence's flagship cyber exercise held in February 2026, deploying a multi-tenanted Elastic Cloud infrastructure to support 40 Blue Teams from 29 countries. The exercise infrastructure ingested 800,000 events per second across 5,000 virtual systems spanning a hybrid environment of AWS and the CR14 cyber range, managed entirely through Infrastructure as Code using Terraform. Elastic also provided custom artificial intelligence (AI) agents built with Agent Builder, native AI features such as the AI Assistant for Security and Attack Discovery, and UK-tenanted AWS Bedrock models with strict guardrails and full audit logging.

Why it matters: Military cyber operators and defence organisations benefit from understanding how enterprise security platforms scale to support large-scale force-on-force exercises; practitioners deploying multi-tenant endpoint detection and response (EDR) and security information and event management (SIEM) infrastructure at scale can reference the architectural patterns, data isolation techniques, and automation approaches demonstrated here.
