Cybersecurity Company Horizon3.ai Goes From Strength to Strength
- Customer base and ARR more than doubled year-on-year
- Industry-leading scale: largest single-run pentest to date, safely testing 100,000+ IP addresses
- Media requests with CEO & co-founder Snehal Antani: team@euromarcom.com
London, 15 September 2025 – Horizon3.ai, the leading provider of offensive security solutions, today announced record first-half 2025 results. The company reports that its customer base has grown to around 4,000 organisations worldwide, up 117% year-on-year. Annual recurring revenue (ARR) increased 137% year-on-year. With more than 170,000 penetration tests already completed, Horizon3.ai is on track to exceed 200,000 all-time tests by the end of 2025.
NodeZero is a cloud-based platform that enables organisations and public-sector bodies to run their own penetration tests against their IT estates to validate cyber resilience. Its cloud model keeps costs low, making regular pentesting affordable for mid-market firms. While widely adopted by SMEs, NodeZero is built for enterprise scale: Horizon3.ai counts three of the world’s ten largest companies among its customers, alongside Fortune 500 firms in financial services, pharmaceuticals, automotive, manufacturing and technology.
H1 2025 saw Horizon3.ai execute its largest single-run pentest to date, safely testing more than 100,000 IP addresses for a major municipal transport authority; the company believes this to be the biggest on record.
Horizon3.ai is expanding its global footprint through new partnerships with organisations including NCC Group, Tech Mahindra and Kyndryl. Via these and other partners with access to NodeZero, enterprises worldwide can continuously assess their security posture. This is essential for meeting cybersecurity regulatory requirements (including in the EU) and strongly recommended to defend against attacks that are growing more frequent, severe and sophisticated.
“Risk boils down to three questions: Are you exploitable? What would the business impact be if you are? And are attackers actively using those tactics? Enterprises need clear answers to prioritise action. NodeZero delivers that proof, enabling organisations to focus on what matters most and continuously validate their security posture,” said Snehal Antani, CEO and Co-Founder of Horizon3.ai.
About Horizon3.ai and NodeZero
Horizon3.ai provides a cloud-based platform, NodeZero, enabling organisations and public authorities to run production safe self-attacks on their IT infrastructure to assess their cyber resilience through penetration testing (pentesting). Thanks to its cloud model, the platform offers affordable, regular autonomous pentesting, making it accessible from small to mid-sized, to large enterprises. Horizon3.ai continuously monitors the cybercrime landscape to ensure that newly discovered weaknesses are swiftly integrated into the cloud system. NodeZero not only identifies security flaws but also offers tailored recommendations for remediation. Through this platform, Horizon3.ai helps organisations meet rising regulatory demands for cyber resilience in Governance, Risk & Compliance (GRC), with guidelines recommending an internal self-attack at least once a week.
