Corelight

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.

The company serves security conscious organisations that run complex networks, including larger enterprises and public sector bodies, as well as teams operating in cloud and hybrid environments. These customers typically have dedicated security operations functions and use a mix of tools such as SIEM, SOAR and endpoint platforms. Corelight is designed to fit into that ecosystem by supplying network derived telemetry and analysis that can be forwarded into the systems security analysts already rely on, helping them correlate events, investigate faster and reduce blind spots.

Within the SaaS landscape, Corelight sits in the cybersecurity and security operations space, with a particular emphasis on network detection and response and network security monitoring. The work is inherently technical and product decisions are closely tied to real world attacker behaviour, data quality, and operational usability for analysts. If you are interested in building software that has to be reliable under pressure and useful during incidents, this is the kind of problem domain where small improvements can have a meaningful impact for customers.

People who tend to thrive at Corelight are likely to include software engineers comfortable with data intensive systems, networking concepts and production grade reliability, as well as security engineers and researchers who enjoy translating threat knowledge into practical detections and workflows. There is also scope for product, customer success and solutions roles that bridge technical depth with an understanding of how security teams work day to day. Given the nature of the product, strong collaboration between engineering, security experts and customer facing teams is likely to be important, along with an ability to communicate clearly about complex technical topics.

For job seekers, Corelight may appeal if you want to work on mission driven security products where the end users are practitioners and the feedback loop is grounded in operational outcomes. The environment is likely to suit people who enjoy tackling hard technical problems, care about accuracy and performance, and want their work to be used in real investigations rather than in abstract demos. If you are motivated by helping defenders gain clearer visibility and respond faster, Corelight’s focus on network evidence and security operations provides a concrete, high impact area to build a career.
