Former CrowdStrike and Proofpoint sales executive joins Ent to scale revenue and expand adoption among enterprises

Ent, the AI endpoint security company, today announced the appointment of Kevin Arsenault as chief revenue officer. Arsenault brings more than two decades of sales leadership experience, including senior roles at CrowdStrike and Proofpoint.

Arsenault was part of CrowdStrike’s early sales team and ultimately served as vice president of sales for North America, helping build the business through its growth and 2019 initial public offering. Previously, he served as vice president of worldwide advanced security and information governance sales at Proofpoint, where he helped develop the sales organization ahead of its 2012 IPO.

At Ent, Arsenault will focus on accelerating the company’s revenue growth and expanding platform adoption across large enterprises. His priorities will include scaling the go-to-market organization and strengthening relationships with customers and partners.

“Kevin has helped build some of the most successful companies in cybersecurity,” said Lou Manousos, co-founder and CEO of Ent. “He understands the endpoint market and knows how to scale revenue with a customer-first organization that moves with urgency and owns the outcome. That means helping customers modernize their endpoint security to address AI-driven threats, simplify their legacy security stack, and adopt agents securely.”

“I’ve spent my career helping customers and partners navigate major shifts in cybersecurity, and AI is creating another one,” said Arsenault. “AI agents are moving onto the endpoint with access to applications, data, and credentials, while attacks are unfolding faster than teams can respond. I’m excited to work with our customers and partners to solve these problems and bring Ent’s approach to more organizations by understanding the context and intent behind activity and instrumenting the shift to prevention.”

Arsenault’s appointment follows Ent being named the 2026 CyberSecurity Breakthrough Award winner for “Endpoint Security Innovation of the Year.” The recognition comes as Ent expands its platform to help organizations secure activity involving people, AI agents, applications, data, scripts, tools, and process execution.
