Corelight

corelight.com
Corelight builds security software that helps organisations see what is happening across their networks so they can detect and investigate threats more effectively. Its focus is on turning raw network activity into data that security teams can use, which matters because many attacks move laterally inside environments and can be difficult to spot using endpoint signals alone. In practice, Corelight’s products support monitoring, threat hunting and incident response by providing high quality network evidence that can be integrated into existing security operations.
