Corelight Open NDR vs ObservabilityOS

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.

ObservabilityOS collects structured logs and supports observability workflows across logs, metrics, and traces. It uses rolling statistical Z-score baselines to flag changes in error rates, latency, and CPU usage, then can use GPT-4 or Claude for incident analysis that describes what happened, why, and a suggested hotfix. Log collection options include a JavaScript/TypeScript SDK and a Docker sidecar for local logs or container output. The ingestion API supports native OTLP HTTP/JSON for existing collectors. Listed integrations include OpenTelemetry, GitHub, Slack, Discord, Microsoft Teams, Docker, Kubernetes, PostgreSQL, and Redis. Incident tools include threaded comments, runbooks, health dashboards, SLOs, and live SSE monitoring. The maker says telemetry is scrubbed before storage and sensitive client data is not sent to external LLMs. Plans include a free developer option, a free source-available self-hosted option, and Pro Cloud at $29/mo. The developer plan allows one service, 500MB of logs monthly, and seven-day retention; Pro Cloud lists 10 services, 10GB monthly, and 30-day retention.
