Horizon3 Expands in Singapore for AI Security Push

Horizon3, an AI-native proactive security leader, has announced a significant expansion in Singapore, establishing its ASEAN headquarters and a Regional Centre of Excellence. This strategic move is supported by new investments from EDBI and SG Growth Capital, aimed at addressing the accelerating demand for continuous security validation across Southeast Asia due to the rise of AI-driven cyberattacks.

The expansion aligns with Singapore's cybersecurity agenda, emphasizing the shift from periodic assessments to continuous proof of cyber resilience. Recent reports indicate a substantial increase in infected infrastructure in Singapore, highlighting the urgent need for advanced security solutions.

Horizon3's NodeZero platform autonomously validates attack paths, offers remediation guidance, and retests fixes, providing organizations with continuous, evidence-based visibility into their real-world exposure. This capability is crucial as AI compresses attack timelines from months to hours, making it imperative for security leaders to validate exploitable vulnerabilities.

The company chose Singapore for its concentration of financial institutions, critical infrastructure operators, and its forward-looking approach to cyber resilience and AI governance. Horizon3 plans to scale its go-to-market operations, deepen partnerships, and collaborate with Singapore's cybersecurity ecosystem to secure digital transformation efforts.

This expansion follows Horizon3's substantial US$250 million Series E funding round in August 2026, which valued the company at over US$2 billion. The company was recognized as the Fastest Growing Cybersecurity Company in North America by Deloitte Technology Fast 500 and one of Fast Company's Most Innovative Companies in 2026.
