Horizon3, an AI-native cybersecurity company known for its NodeZero autonomous penetration testing platform, is expanding into Singapore with backing from the Singapore Economic Development Board (EDB) and EDBI, part of SG Growth Capital.
The company is setting up its ASEAN headquarters and a Regional Centre of Excellence in Singapore, a base it will also use to support growth in Australia and Japan. It plans to grow its local headcount across sales, customer and partner operations as it scales up.
The expansion follows a US$250 million Series E round in August 2026, which valued Horizon3 at more than US$2 billion.
Singapore’s cyber threats are growing fast
The timing lines up with what Singapore’s Cyber Security Agency (CSA) has been flagging. Its 2025/2026 Singapore Cyber Landscape report found that AI is increasingly used by threat actors to carry out attacks with more speed and sophistication, and that infected infrastructure in Singapore jumped 142 per cent in 2025 to 284,300 systems.
Horizon3’s pitch is that organisations need to move past periodic security assessments and prove, continuously, that they can withstand an attack. Its NodeZero platform autonomously tests which vulnerabilities can actually be exploited, gives remediation guidance, then retests to confirm the fix worked.
“Singapore’s regulatory and national cybersecurity agenda signals a broader shift across the region: boards can no longer rely on confidence or compliance checklists; they must be able to prove cyber resilience and prove they are prepared for AI-enabled cyber warfare,” said Snehal Antani, CEO and co-founder of Horizon3. “As AI compresses attack timelines from months to hours, the strategic question for security leaders is not how many vulnerabilities they have, but whether they can continuously validate what is actually exploitable and verify that remediation has reduced business risk.”
Gareth Cox, Horizon3’s vice president for Asia Pacific and Japan, said Singapore was chosen for its mix of financial institutions, critical infrastructure operators and regional headquarters, alongside clear direction on cyber resilience and AI governance. “This makes it the ideal launchpad for supporting organisations across Malaysia, Indonesia, Thailand and beyond as they shift from tick-box compliance to outcomes-based security,” he said.
EDBI backs the bet on continuous validation
Yeung Chia Li, senior partner at EDBI, said Horizon3’s technology fits where Singapore and the region are heading on cybersecurity. “The establishment of its ASEAN headquarters and Regional Centre of Excellence in Singapore reflects the company’s long-term commitment to the region and will contribute to the growth of Singapore’s cybersecurity ecosystem,” he said, adding that EDBI would also help connect Horizon3 to talent and partners across Southeast Asia.
Horizon3 said the Singapore base will also be used to deepen partnerships with managed security service providers, systems integrators and cloud providers, and to work with CSA-led initiatives on AI for cybersecurity and critical infrastructure resilience.
More than 7,000 organisations use Horizon3’s platform, including defence agencies, Fortune 10 companies, multinational banks and healthcare providers. The company was named the fastest-growing cybersecurity company in North America by the Deloitte Technology Fast 500, and one of Fast Company’s Most Innovative Companies for 2026.
