Principle Security Architect at Eversource Energy4.0I've used Corelight Open NDR for three years, finding its Suricata engine crucial for IoC alerting and visibility. It's an excellent, stable product with great support, delivering positive ROI and vital structured evidence for AI.
Account Executive at Fishtech Group4.0I use Corelight for east-west traffic visibility, finding it stable, scalable, and offering immediate ROI due to its low cost and easy setup. However, I note that new features haven't been added recently.
Technical Sales Manager at Spire Solutions3.5I rate Corelight a 7/10. It's excellent for traffic monitoring, stable, and scalable with powerful threat detection and integrations. However, I found its architecture complex, setup difficult, and pricing high.
Manage Consultant at SITE4.0I use Corelight for customer incident response. It's easy to deploy, handle, and scalable, with good support. I'd improve the interface's interactivity and feature access. Despite this, I rate it 8/10, preferring it for its rule-based approach over alternatives.
Pre Sales Technician at DotForce5.0I find Corelight an excellent, stable, and affordable solution for network traffic analysis, providing crucial data for cyber security. It integrates well and simplifies incident remediation, despite initially lacking machine learning. I highly recommend it.
Chief Executive Officer at NetMetrix4.0I use Corelight for security, valuing its embedded Suricata IDS. While stable and scalable, it is expensive and needs a GUI. Setup is easy, and support is good. I rate it 8/10.
