Horizon3, a U.S. security company that sells AI-driven proactive testing software, will establish its ASEAN headquarters and a regional center of excellence in Singapore.
In a statement on Monday, San Francisco-based Horizon 3 said the expansion is backed by new investments from EDBI and SG Growth Capital, the strategic investment platform set up by the Singapore Economic Development Board and Enterprise Singapore.
The company said the Singapore base will also support its operations in Australia and Japan, and that it will add local staff across sales, customer and partner operations. Horizon3 said the expansion follows its $250 million Series E round, announced in August 2026 at a valuation of more than $2 billion.
Horizon3 said the move responds to growing demand across Southeast Asia for continuous, evidence-based security testing as AI-driven attacks become faster and more sophisticated.
The company’s NodeZero platform can test a customer’s live network for exploitable attack paths, and can recommends fixes and confirm the result. This can replace periodic testing with continuous validation, Horizon3 noted.
Snehal Antani, CEO and co-founder of Horizon3, said boards can no longer rely on confidence or compliance checklists and must be able to prove resilience. AI is compressing attack timelines from months to hours, so security leaders need to check continuously risks and the quality of fixes.
Gareth Cox, vice president for Asia-Pacific and Japan at Horizon3, said the company chose Singapore because it has a concentration of financial institutions, critical infrastructure operators, and regional headquarters. Singapore also features a forward-looking direction on cyber resilience and AI governance.
He also said Singapore would serve as a base for Malaysia, Indonesia, Thailand, and other markets.
Horizon3 said the Singapore operation will expand go-to-market work across enterprise, mid-market and public-sector customers. The expansion can deepen partnerships with managed security providers, systems integrators, and cloud providers, and collaborate with Singapore’s cybersecurity initiatives. Horizon3 will support the digital transformation agenda in line with Singapore’s National AI Strategy.
