CISO

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.

WHAT YOU’LL ACHIEVE

• Set Ent's company-wide security strategy and roadmap, with priorities, ownership, and measurable outcomes that reflect our stage, risk profile, and customer commitments.

• Serve as a hands-on security leader. Personally drive critical assessments, control design, remediation, and incident work while building a focused internal team and using outside partners where they add leverage.

• Own security risk across identities, employee endpoints, SaaS applications, cloud infrastructure, company data, the software supply chain, and third-party vendors.

• Partner with Engineering and Product to embed security into architecture and the software development lifecycle, including threat modeling, secure design reviews, vulnerability management, secrets and dependency management, logging, monitoring, and remediation.

• Establish and continuously improve core controls for identity and access management, device security, privileged access, data protection, configuration management, and employee onboarding and offboarding across Ent's cloud-first environment.

• Build and lead incident response, including detection and escalation processes, investigation, containment, communications, tabletop exercises, post-incident reviews, and improvements to business continuity and disaster recovery.

• Lead Ent's security assurance and compliance program. Translate requirements from frameworks and programs such as SOC 2, ISO 27001, FedRAMP, and customer-specific standards into durable controls, with clear judg
