“Cybersecurity is a last-mile trust business,” said Snehal Antani, Co-Founder and CEO of Horizon3. “The technology matters, but the relationship often decides the outcome. Our partners have already built deep trust with CISOs over the years. They already have master service agreements in place. They already understand the customer’s environment and procurement process. They are uniquely positioned to extend our reach and accelerate our sales cycles,” said Antani.

From day one, Horizon3 was built as a channel-first company. When partners bring NodeZero® into their accounts, they are not simply reselling software. They are bundling remediation, incident response, vCISO advisory, and other high-value services that create recurring revenue and measurable outcomes. Horizon3 deliberately leaves that high-margin services layer for partners because their success is the most efficient path to scale. That model is already delivering results. Demand for the NodeZero Proactive Security Platform has driven 120% year-over-year ARR growth, supported by more than 310,000 production-safe autonomous security tests across more than 7,000 customer environments. Today, 90% of Horizon3’s business flows through partners.

“Our global partner ecosystem is central to our mission at Horizon3,” said Tim Mackie, Vice President of Global Channels and Alliances at Horizon3. “This investment signifies a long-term commitment to ensure our partners have the technology and expertise to deliver security their customers can prove, at the speed and scale the market demands.”

The $20 million commitment strengthens the systems that make partner-led growth work at scale:

  • Expanded channel leadership with dedicated executives focused on Service Providers, Strategic Alliances, and North America Channels, providing deeper technical expertise, stronger co-selling, and support for building profitable proactive security practices.

  • Investing to develop a frictionless transaction experience with Horizon3, enabling partners to accelerate deal registration, quoting, fulfillment, and expansion.

  • Training and enablement programs designed for role-specific learning paths and certifications for sales professionals, systems engineers, solution architects, and platform administrators so partners can ramp faster and deliver with confidence.

  • Go-to-market incentives for high-performing partners including marketing development funds and additional resources to accelerate growth.

Horizon3 continues to expand the ecosystem around NodeZero through strategic technology alliances and joint go-to-market initiatives. Recent partnerships with World Wide Technology and Brinqa extend proactive security into exposure management, remediation orchestration, and cyber resilience programs, helping customers move from visibility to measurable risk reduction.

New platform capabilities further expand the addressable market partners can serve. NodeZero® WebApp extends the platform across web applications, identities, infrastructure, and cloud environments, enabling both organizations and the partners who support them to validate complete attack paths from initial access to business impact.

The company is also increasing investment in bringing the partner community together and generating joint demand. Following its annual Global Partner Conference: Americas in April, Horizon3 will host its second European Partner Conference on September 16–18. As a Pinnacle sponsor of CrowdStrike Fal.Con 2026, Premier sponsor of Fal.Con Europe, and Platinum sponsor of this year’s AWS re:Invent, along with expanded participation at Zenith Live, CriblCon, and other strategic industry conferences, Horizon3 is creating more opportunities for partners to engage customers and showcase joint solutions.

“The future of cybersecurity isn’t finding more vulnerabilities; it’s continuously understanding and reducing exposure,” Mackie said. “Our partners are at the center of that shift. We are committed to giving them the training, tools, and go-to-market support they need so they can proactively prove that their customers are secure and build thriving practices while doing it.”
