Our take
Corelight is a software company that integrates machine learning into cyber and cloud security. It develops NDRs (Network Detection and Response systems) alongside virtual, software and cloud sensors to better protect enterprises and institutions.
The company's most popular product is the Zeek Network Security Monitor, which is used by the likes of Amazon and Mozilla. It is also continually developing new products (such as a Cloud Sensor for Amazon Web Services) as the nature and complexity of cyber threats continue to grow.
Launched back in 2013, the company has been around for a while now, but it continues to keep up to date with the changing market. In 2024, Corelight secured immense Series E funding as it capitalises on the booming AI and cyber defense markets.
