Horizon3 launches ASEAN HQ in Singapore with state-backed funding after $250M Series E

Horizon3 announced on October 19, 2026, that it is expanding its operations in Singapore to serve as its new ASEAN headquarters. The company will establish a Regional Centre of Excellence there, supported by strategic investments from EDBI and its parent organization, SG Growth Capital. This expansion aims to meet growing demand for continuous security validation across Southeast Asia.

The investment comes from SG Growth Capital, the strategic investment platform established by the Singapore Economic Development Board and Enterprise Singapore. According to Horizon3, this funding supports the company’s growth in early to late stages. The firm will increase its local headcount to scale sales, customer support, and partner operations. This Singapore base will also support Horizon3’s broader expansion into Australia and Japan markets.

Regional Cybersecurity Context

This expansion aligns with Singapore’s national cybersecurity priorities and a regional shift toward continuous proof of cyber resilience. The Singapore Cyber Security Agency reported in its 2025/2026 Singapore Cyber Landscape report that threat actors are increasingly using AI to conduct attacks with greater speed and sophistication. The agency noted that infected infrastructure in Singapore rose by 142% in 2025, reaching 284,300 systems.

Snehal Antani, CEO and co-founder of Horizon3, stated that boards can no longer rely on confidence or compliance checklists. He emphasized that organizations must prove their cyber resilience and preparedness for AI-enabled cyber warfare. Antani noted that AI compresses attack timelines from months to hours, making continuous validation of exploitable vulnerabilities critical. The strategic question for security leaders is whether they can verify that remediation has reduced business risk.

Market Strategy and Leadership

Gareth Cox, vice president of Asia Pacific and Japan at Horizon3, explained that Singapore was chosen for its concentration of financial institutions and critical infrastructure operators. He highlighted the country’s forward-looking direction on cyber resilience and AI governance as key factors. Cox pointed to the Cyber Trust Mark roadmap and tightened technology-risk notices from the Monetary Authority of Singapore as evidence of measurable security expectations.

The expansion follows Horizon3’s US$250 million Series E funding round announced in August 2026, which valued the company at more than US$2 billion. Cox stated that the company is working with boards and CISOs to demonstrate with evidence that security investments are closing the most dangerous attack paths. The goal is to help organizations in Malaysia, Indonesia, Thailand, and beyond shift from tick-box compliance to outcomes-based security.

What should you do?

Security leaders should review their current vulnerability management processes to ensure they provide evidence of actual risk reduction. Organizations should assess whether their security tools can autonomously validate attack paths rather than just listing potential weaknesses. Teams should verify that remediation efforts are continuously tested to confirm that business risk is lowered.

What to do and how to stay safe: Horizon3

• Evaluate if your security validation processes provide continuous, evidence-based visibility into real-world exposure rather than periodic snapshots.
• Assess whether your organization can distinguish between theoretical vulnerabilities and those that are actually exploitable by attackers.
• Review remediation workflows to ensure they include retesting steps that verify fixes have effectively reduced business risk.
• Align security reporting with measurable outcomes to demonstrate cyber resilience to boards and regulators, moving beyond simple compliance checklists.
