Sunnyvale, California-based cloud security company Fortinet said on Tuesday it will acquire Edinburgh-based cyber security software firm ZoneFox.

Fortinet has a stock market value of around $14 billion, according to Reuters data.

ZoneFox’s customers include healthcare firm Craneware, Zenith Bank and video gaming giant Rockstar Games.

ZoneFox CEO Jamie Graves said:“We’re pleased to join the Fortinet team and bring together our shared vision of alleviating CISO concerns about insider threats.

“Integrating our solution with the Fortinet Security Fabric will allow us to extend our reach to a broad spectrum of Fortinet and third-party solutions to solve customers’ most difficult challenges in network security.”

Fortinet CEO Ken Xie said:“Enterprise organizations are experiencing a dramatic increase in the number of endpoints and users accessing data and cloud resources, which is also increasing the need to defend against insider threats.

“In fact, 30 percent of breaches involved insiders acting negligently or maliciously …

“By combining ZoneFox’s cloud-based threat-hunting technology with Fortinet’s existing endpoint and SIEM security offerings, we are well positioned to provide our customers with an integrated approach to defend against insider threats, eliminate network blind spots and protect today’s expanding attack surface with automation and machine learning.”
