Chief Information Security Officer (CISO)
About Ent
Ent is the intent-aware workspace security platform for securing human and AI-driven work. Built to protect productivity, the new attack surface, Ent understands not just what users and agents do but why, and intervenes at the moment of risk before incidents occur. Where existing tools see events, Ent sees intent, so security teams can step in at the moment of risk instead of investigating days later. Founded by Lou Manousos and Brandon Dixon, co-founders of RiskIQ (acquired by Microsoft) and the team behind Microsoft Security Copilot, Ent is in production with Global 2000 customers across hospitality, financial services, and defense, and backed by Decibel, Sequoia, Crosspoint Capital, Craft Ventures, Shield Capital, Felicis, and In-Q-Tel. We’re now hiring the team that will define this category.
How We Work
Customer first. The product and the business are built around problems we’ve watched real security teams struggle with — not the other way around. Every roadmap conversation starts with what a CISO told us last week.
Humble. No drama. We hire people who share the mission and trust each other to deliver. Teamwork over showmanship. Accountability over politics. The work speaks louder than the person doing it.
Urgency. The window to build a durable security company in the AI era is open right now and it will not stay open. The shot clock has started. We move at the speed of the people we want to protect.
About the Role
We are seeking a hands-on Chief Information Security Officer to build and lead Ent's internal security program as we scale. You will own the security of our people, systems, infrastructure, product development environment, and company data. You will work closely with our founders and leaders across Engineering, Product, Legal, People Operations, IT, and Go-to-Market to make clear, risk-based decisions and earn the trust of large enterprise and government customers.
This is an internal security leadership role with meaningful customer-facing responsibility. Because Ent is building AI-native endpoint security, you will need deep technical credibility, strong operating judgment, and the ability to turn high security standards into practical controls that protect the company without slowing the team down. You will set the strategy, personally drive the highest-priority work, and build the team and operating model Ent needs for its next stage.
