Network detection and response firm ExtraHop has named Rob Greer as its new chief executive officer, following a “banner year” in 2024.
ExtraHop delivered more than $300m in total bookings in 2024. The company closed the year with more than 40 different customers contributing $1m-plus in annual recurring revenue (ARR), and added “several” new Fortune 100 clients, including major US banks and global corporations, to its roster.
Greer, an industry veteran with a record of leading and scaling network security companies, will work alongside outgoing CEO Greg Clark, who is transitioning to executive chairman of the ExtraHop board of directors, where he will remain an active member of the leadership team, supporting customers, partners, and strategic initiatives, said the company.
“ExtraHop achieved tremendous success in the last year, growing its customer base, disrupting the market with industry-leading innovations, and receiving prestigious analyst recognition and awards,” said Clark. “We are well-positioned to accelerate our roadmap as more organisations realise the power of the RevealX NDR platform and its ability to solve many of their security challenges.”
Greer brings 30 years of experience, including roles at HP Tipping Point, Forescout Technologies, Blue Coat Systems, and SonicWALL, where he supported the largest enterprises globally. Greer most recently served as general manager of Broadcom’s enterprise security group division, overseeing the merger between Symantec and Carbon Black. He is also an operating partner at Crosspoint Capital Partners.
“The ExtraHop team has laid an incredible foundation in the NDR market, garnering a loyal customer base and revolutionising how enterprises approach cybersecurity and risk management with the most in-depth network telemetry,” said Greer. “We’ve now entered a new phase of growth that will empower us to reach even more customers, with a robust platform that supports all of their network-centric detection and response needs.”
