Elastic Network Security

Elastic Network Security is a network detection and response and security analytics capability within Elastic Security, designed to analyze network traffic, packet captures, and flow records to identify cyber threats, anomalous communications, and lateral adversary movement across enterprise networks. By indexing network telemetry in Elasticsearch, it enables security operations teams to correlate network behavior with endpoint and cloud logs for comprehensive threat hunting.

The solution ingests network telemetry from network sensors, Zeek, Suricata, NetFlow, IPFIX, and firewall logs across on-premises data centers, branch networks, and multi-cloud environments. It integrates natively with the Elastic Common Schema, MITRE ATT&CK detection rules, and security orchestration systems to automate alert generation and incident investigation workflows. Common organizational use cases include detecting command-and-control communications, identifying unauthorized data exfiltration, uncovering lateral movement across network segments, and investigating suspicious DNS traffic patterns.

With the high-speed search and machine learning anomaly detection capabilities of the Elastic Stack, Elastic Network Security empowers analysts to detect stealthy network intrusions that bypass traditional perimeter defenses. Security teams can pivot from high-level network dashboards down to individual packet flows in seconds, accelerating forensic investigation workflows. The platform enhances network visibility, strengthens threat hunting capabilities, and provides comprehensive network defense across modern enterprise infrastructures.
