Corelight
Corelight processes network traffic to generate detailed security data for analysis. It leverages open-source Zeek to provide context-rich insights that support threat detection and investigation.
Why these ratings?
Cyberse perspective
Summary by Cyberse
Microsoft Sentinel may be considered a good fit for you due to its powerful capabilities.
Here’s a few tips on how to maximize its capabilities:
We use the following criteria to rate this product’s functionality:
Cost considerations
Corelight lists about $6k–$9k per Gbps per year and entry appliances are around $19k annually. Signature detection, smart PCAP, fleet management and 24×7 support require extra subscriptions, so full coverage means several add-ons. Competitors bundle those functions, so Corelight’s total cost to scale sits at the higher end even though its list prices are public.
Functionality
Corelight delivers high-fidelity detection via Zeek data and Suricata IDS but does not provide firewall functions or traffic enforcement. The product offers passive alerts and some machine-learning analytics yet omits inline IPS, sandboxing, TLS decryption and segmentation expected from modern NGFW suites. Because these preventive controls are missing, its functionality aligns more with monitoring than with a full network security stack.
Compatibility
Corelight deploys on rack-mount sensors, virtual machines, containers, and is offered in AWS and Azure marketplaces. Native IPv6 support and Zeek-based APIs stream data directly into Splunk and other SIEMs without coding. These deployment and integration options let security teams drop Corelight into nearly any network environment with minimal effort.
User experience
Many reviewers find Corelight easy to deploy and say its dashboards make network events clear. However, other users note the console still lacks a polished GUI, the setup feels complex, and new analysts require additional training, so the overall experience sits in the middle of the pack
Customer support
Corelight offers round-the-clock assistance and an hour-or-less initial response for critical tickets, and the Enterprise plan ships replacement hardware next business day while guaranteeing the same one-hour SLA for P1 issues. These commitments align with 24×7 access, sub-hour response, and rapid RMA standards in the rubric. An online knowledge base and included Technical Account Manager further strengthen the support experience.
