About the job

Requirements
  • At least 5 years carrying a quota in a full-cycle closing role selling cybersecurity; endpoint security experience is preferred.
  • Experience selling to CISOs and their teams, with the ability to discuss technical topics with a security architect without relying on a sales engineer to answer everything.
  • Existing, current relationships with security leaders, with the ability to explain how those relationships were built and their value.
  • Experience selling to organizations with 5,000 or more employees, navigating multi-stakeholder deals, technical evaluations, security reviews, and sales cycles measured in quarters.
  • Ability to self-source a meaningful share of pipeline and explain the percentage and methods used.
  • Ability to respond to call reviews and coaching by incorporating feedback into subsequent calls; willingness to participate in pitch practice and deal reviews.
Responsibilities
  • Own a quota and run the full sales cycle from first conversation through signature and a clean handoff.
  • Open named accounts through existing relationships and build additional pipeline through outbound activity, networks, events, and partners.
  • Build account plans covering organizational structure, security priorities, budget cycles, incumbent solutions, and paths to decision-makers.
  • Run technical evaluations with security teams by scoping proofs of value, working with engineers, and reaching clear decisions rather than allowing pilots to stall.
  • Engage multiple stakeholders, including CISOs, security architects, IT and identity owners, procurement, legal, and executive sponsors, and build a business case that can withstand budget review.
  • Manage enterprise security reviews, privacy reviews, legal redlines, and procurement early in the sales process.
  • Maintain an accurate forecast by tracking deal status, next steps, and quarterly outcomes.
  • Share customer objections, competitive patterns, and product gaps with internal teams so field learning informs the roadmap and sales pitch.
  • Use AI tools for account research, preparation, follow-up, and call review, and share effective practices with the team.
Desired Qualifications
  • Endpoint security experience.
  • Experience as an early seller at a startup before a sales playbook existed.
  • Experience using a formal sales methodology and the ability to assess where it is useful.
  • Experience selling through partners or resellers alongside a direct sales motion.
  • Experience closing a seven-figure deal or landing a first customer in a regulated industry.
  • Experience working a territory outside the United States.
  • Interest in applying AI to sales.

About the company

Ent provides an intent-aware workspace security platform that preemptively prevents security incidents by interpreting the intent behind user and AI agent actions in real time. A lightweight endpoint agent and a browser extension monitor activity and compare it to corporate policies, triggering automated interventions before risky actions complete. It is hosted in the customer’s cloud and extends existing security stacks like EDR, SIEM, SOAR, and IAM rather than replacing them. Its goal is to help enterprises manage insider risk, govern AI usage, and prevent data loss for both humans and AI agents in modern work environments.

AI endpoint security firm Ent named to 2026–27 Fortune Cyber 60

Ent, an AI endpoint security company, has been named a winner of the 2026–27 Fortune Cyber 60, a list of 60 leading venture-backed cybersecurity companies. Lightspeed Venture Partners and Amazon Web Services present the list in partnership with Fortune. Lightspeed assessed more than 300 startups on annual recurring revenue, growth, and business operations, and Fortune validated the final list. Ent runs AI on the endpoint to understand human and agent activity and its intent, then controls execution before risky behaviour becomes an incident. The company emerged from stealth in June and recently appointed Kevin Arsenault chief revenue officer. A Lightspeed survey found AI agents are in production at 77% of surveyed companies, yet only 20% of those using or exploring them have a complete inventory.

Ent appoints Kevin Arsenault chief revenue officer. Former CrowdStrike and Proofpoint sales executive joins Ent to scale revenue and expand adoption among enterprises. Ent, the AI endpoint security company, 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. "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." - Kevin Arsenault, CRO at Ent 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.

Ex-Microsoft duo behind Security Copilot raises $100M seed to catch AI threats before they strike — TFN

Ent, the endpoint security startup founded by ex-Microsoft leaders behind RiskIQ and Security Copilot, has raised $100M in seed funding to stop AI-era threats before they strike.

Ent emerges from stealth to bring prevention back to cybersecurity.

Ent emerges from stealth to bring prevention back to cybersecurity. Ent emerged from stealth with $100 million in seed financing. The company is pioneering a new approach to cybersecurity built around the simple belief that AI compresses the time between compromise and impact; prevention must once again become the primary objective of security. Ent's platform helps organizations understand and intervene in risky actions by humans and AI agents before they become incidents. Ent is already deployed with Global 2000 customers across hospitality, financial services, and defense. Customers use Ent to detect insider risk, govern AI usage, prevent data loss, stop last-mile threats, and investigate incidents with the full behavioral context of what happened, why it happened, and what should happen next. "Security has been stuck in a reactive loop for over a decade, but AI-powered attacks require new thinking," said Elias Manousos, CEO and co-founder of Ent. "AI is changing both how people work and how quickly attackers can act. What once took days now happens in seconds. By the time traditional security systems detect a problem, it is too late. We believe the future of security lies in understanding intent in real time across people and AI agents and stopping risk before it becomes an incident." Prevention requires a new layer at the workspace where work happens, across the browser, apps, AI workflows, and agents. Existing tools are blind because they collect at the wrong layer, tied to process and file events, and respond too late. As enterprises consolidate the platforms that protect endpoints, identities, applications, and data, the layer that reads intent across humans and AI agents in real time becomes the critical one. Ent operates at that layer. Hosted in the customer's cloud with complete data sovereignty, Ent runs as a lightweight agent that brings AI reasoning to endpoints. The platform observes behavior across applications, browsers, workflows, data movement, and local runtimes; evaluates human and AI agent intent at the moment of use, applies customer-defined policy, and acts through configurable, just-in-time interventions before incidents occur. The funding is led by Decibel, with participation from Sequoia, Crosspoint Capital Partners, Craft Ventures, Shield Capital, Felicis, and In-Q-Tel (IQT). "AI has been a killer app for hackers and offensive researchers, but the industry is waiting for a novel defensive solution that can keep up with the modern era of LLMs," said Jon Sakoda, Founding Partner at Decibel. "Ent has reimagined what is possible to protect the endpoint by using specialized AI models and adaptive policy enforcement to detect and prevent malicious activity in real time. It's a game changer for cybersecurity teams who need a paradigm shift to defend their workforce against LLM-based attacks." "For a decade, endpoint security has relied on signals that arrive after the user's action is complete," said Konstantin Buhler, Partner at Sequoia. "By running AI reasoning directly on the device, Ent moves from detection to prevention at the moment of decision. That shift is where the next era of endpoint defense gets built." "We have entered a new era defined by AI-powered attacks, one that demands a return to prevention and resilience," said Greg Clark, Co-Founder and Managing Partner, Crosspoint Capital Partners. "The level of inference required to stop threats before they materialize must now live directly on the endpoint. Ent is leading this fundamental shift in endpoint protection." "We are working with agencies where AI adoption is outpacing the ability of most enterprises to govern it, and where forensic clarity matters as much as prevention. Ent gives them both," said Steve Bowsher, CEO at IQT. "They can see what people are doing with AI in the moment, and they have a comprehensive record of what happened on every device." Ent's team brings together engineers and security operators with deep enterprise experience. The company's advisors include former CISOs of Google, Aetna, and MassMutual, the former Director of the NSA, and the former CVP of Microsoft Azure Cloud Security. The new funding will support continued hiring across engineering and go-to-market, while accelerating Ent's roadmap across AI governance, threat prevention, security integrations, and multimodal endpoint intelligence. Ent is generally available today for Windows, macOS, Linux, and browser-extension deployments.
