Corelight Open NDR vs Elastic Security

Corelight Open NDR turns network and cloud traffic into evidence for security operations. Its detection combines machine learning, behavioral analytics, curated signatures and threat intelligence, with real-time detection and anomaly explanations. Automated triage and integrated response workflows provide context for containing threats. The platform brings network security monitoring, intrusion detection, static file analysis and intelligent packet capture together. It handles network traffic, packets, flow logs, cloud network traffic, protocol logs and files. Deployment options include physical, software, virtual, cloud and flow-log sensors across on-premises, air-gapped, hybrid and multicloud environments. Cloud-native sensors support AWS, Azure and Google Cloud; software sensors support Linux-based systems. Physical and software sensors are built for environments at 100+ Gbps scale. Native integrations cover SIEM, XDR, SOAR and cloud platforms, including Splunk, CrowdStrike, Microsoft, Elastic and AWS. A Logs API and MCP server support programmatic access. Pricing is on request, with capacity-based licensing. Corelight serves large enterprises and government agencies in more than fifteen countries.

Elastic Security combines SIEM, XDR, endpoint security, and cloud security for detecting, preventing, and responding to cyber threats. Detection options include prebuilt and customizable rules, machine-learning anomaly detection, and threat hunting. Elastic Defend uses machine learning, behavioral analysis, and prebuilt rules to address endpoint threats; cloud capabilities cover cloud and Kubernetes security posture management, workload protection, and vulnerability management. Elastic Workflows can automate triage, enrichment, response, notifications, and case management. Elastic lists more than 400 prebuilt integrations and up to 1,000 total security and data-source integrations, alongside native OpenTelemetry support. The software can run on Elastic Cloud or self-managed infrastructure, with APIs and query options KQL, Lucene, and ES|QL. The free Basic plan includes SIEM, XDR, and host security analysis. Elastic Cloud Hosted and Serverless offer a 14-day free trial. Security Analytics Essentials is listed at $0.09 a month, with retention priced separately; Essentials also includes endpoint protection, while retention is priced separately at as low as $0.017 per retained GB per month. Elastic Cloud uses HTTPS for internet-facing and inter-node communications and encrypts cluster data at rest.
