Agentic AI in Cybersecurity

Security operations centers face cybersecurity fatigue as analysts contend with constant alerts, false positives, and compliance demands, and although agentic AI can automate tasks, it often lacks the tacit knowledge and business context held by experienced staff. The post argues that embedding policies and definitions separately in individual AI agents creates duplicated, inconsistent knowledge, causing agents to make conflicting assessments of concepts such as critical assets, acceptable risk, or inactive accounts. It proposes a centralized Cybersecurity Knowledge Layer that combines a security ontology defining assets, controls, policies, and operational constraints; current enterprise data such as telemetry, inventories, and threat intelligence; and contextual memory containing past decisions, false positives, and remediation outcomes. Neo4j is presented as infrastructure for this layer because graph-based data modeling supports multi-hop attack-path analysis, GraphRAG combines semantic retrieval with network topology, temporal memory preserves changing states over time, and Model Context Protocol integrations can connect specialized agents to shared governed context. By separating agents’ reasoning and action capabilities from the organization’s central knowledge, the approach aims to make automation more consistent, explainable, adaptable, and capable of preserving institutional learning across changing AI models and security tools.
