Our take
When trying to become more cybersecure, many businesses find themselves operating blindly, as they lack the necessary insights to understand potential attack points within their networks. This information gap has led to an alarming vulnerability, leaving organizations exposed to threats that remain unseen.
ExtraHop provides organizations with the network visibility and threat detection capabilities they need. Through its cyber defense platform, the company enables businesses to detect and respond to advanced cyber threats before they can compromise their operations. Importantly, its use of cloud-scale AI and ML means this is done in real time.
With a portfolio of over 70 AI and ML patents, ExtraHop has built a reputation as an innovator in the space. It has been able to accelerate growth since its acquisition by Bain Capital and Crosspoint Capital in 2021, and fresh funding will ensure it is able to continue expanding capabilities and reinforcing its already strong position.
