The Ministry of Defence faces an unacceptable cyber risk due to escalating malicious cyber activity, pressuring defence security operations centres. Current detection times are too slow, taking days or weeks to identify sophisticated threats. The MoD's Digital Strategy prioritizes rapid detection and response through integrated cyber defenses. This requires unified capabilities to reduce mean time to detect and respond, not just adding more tools. Elastic Security offers AI-powered analytics and workflows for defence SOCs to automate processes and improve visibility. Attack Discovery correlates alerts into attack narratives, revealing adversary movements and prioritizing genuine threats. Machine learning components identify known and novel attack methods, preventing overwhelming analysts. Elastic AI Assistant acts as a copilot, automating tasks like alert summarization and suggesting response actions. It uses custom defence knowledge sources to align AI insights with MoD requirements. This automation addresses cybersecurity gaps in people, processes, and technology within the MoD.
