James C Foster becomes CEO of eSentire
His appointment follows a year of exec reshuffles at the company
Canada-HQ cybersecurity vendor eSentire has appointed James C Foster as its new CEO, with Kerry Bailey retiring after an eight-year tenure.
The new head of the company brings nearly 30 years of IT experience.
He joins from IronCircle, where he served as CEO since August until its sale to cybersecurity workforce development and talent marketplace firm QuickStart last month.
Foster previously founded and led Ciphent since 2006, until its acquisition by Accuvant in 2010.
He also founded ZeroFox, where he assumed the role of CEO for 11 years, during which he achieved 30 consecutive quarters of ARR growth and completed five acquisitions.
“The threat landscape is evolving faster than ever, and organisations need a cybersecurity partner who can meet that pace with both agentic and human expertise,” said Foster.
“I am honoured to work alongside this outstanding team and ensure that eSentire is delivering on our mission: hunting, investigating and stopping cyberthreats before they become business-disrupting events.”
Bailey added: “Foster brings exceptional vision, deep industry expertise and a proven track record of building world-class security organisations.
“I have every confidence that under Foster's leadership, eSentire will continue to raise the bar for our customers, our partners and the industry as a whole.”
The announcement also coincides with the appointment of Tim O’Rourke as CMO and Dani Averill as chief of staff, who also joins from IronCircle.
The vendor has made several other leadership changes over the past 12 months.
In January, it named Leslie Marinaro as chief customer officer.
In August, Dustin Hillard was promoted to chief product and technology officer.
A month earlier, Mark Gillett stepped up as chief product officer.
These developments come despite a Reutersreport in 2024 stating that the owners of eSentire were exploring options, including a potential sale that could value the company at around $1bn (£747.4m), including debt, according to sources close to the matter.
Established in 2001, the vendor works with more than 2,000 organisations across over 80 countries and 35 industries.
