Horizon3 is positioning itself to capture the accelerating demand for automated security validation across Southeast Asia by establishing its ASEAN headquarters and a Regional Centre of Excellence in Singapore. This strategic move, backed by new investments from EDBI and SG Growth Capital, aims to address a critical gap in regional defense as AI-driven cyberattacks increase in speed and sophistication. The company is leveraging this expansion to support broader growth into Australia and Japan, signaling a shift toward continuous, evidence-based resilience. This development follows a US$250 million Series E funding round in August 2026, which valued the firm at over US$2 billion, providing the capital necessary to scale sales, customer, and partner operations within the high-growth ASEAN digital economy.
EDBI and SG Growth Capital Back Singapore Expansion
The expansion into Singapore is fueled by strategic investments from EDBI and SG Growth Capital, a platform established by the Singapore Economic Development Board and Enterprise Singapore. These investments are intended to support Horizon3’s regional growth and its mission to provide continuous, evidence-based cyber resilience. By establishing a local presence, Horizon3 intends to scale its go-to-market operations across enterprise, mid-market, and public-sector segments throughout Southeast Asia. The company also plans to deepen its integration with local Managed Security Service Providers (MSSPs), systems integrators, and cloud providers to deliver its validation services at scale.
Beyond direct sales, Horizon3 is aligning its growth with Singapore’s national cybersecurity priorities and the broader regional movement toward outcomes-based security. The company intends to collaborate with the local cybersecurity ecosystem, including initiatives led by the Cyber Security Agency (CSA) regarding AI for cybersecurity and Critical Information Infrastructure (CII) resilience. This expansion is timed to coincide with a period of heightened regional risk; according to the CSA’s 2025/2026 Singapore Cyber Landscape report, infected infrastructure in Singapore rose 142% in 2025, reaching 284,300 systems. Horizon3 is positioning its presence to help organizations navigate this increasingly complex and high-velocity threat environment.
NodeZero Technology and the Shift to Continuous Validation
At the core of Horizon3’s regional strategy is NodeZero, an AI-native platform designed to autonomously validate attack paths and provide remediation guidance. As digital environments grow more complex, the company argues that traditional, periodic security assessments are becoming insufficient. NodeZero is designed to function as an "AI hacker," testing defenses at machine speed to uncover exploitable vulnerabilities and then retesting to verify that fixes are effective. This creates what the company describes as a continuous "hack-fix-verify" loop, providing security teams with visibility into real-world exposure rather than static compliance checklists.
The technical necessity for this approach is driven by the compression of attack timelines. Horizon3 notes that AI can reduce the time required for successful attacks from months to mere hours. By providing continuous, attacker-validated proof of resilience, the platform aims to help organizations prioritize vulnerabilities that pose actual business risk. This shift is particularly relevant in Singapore, where regulatory bodies like the Monetary Authority of Singapore (MAS) have tightened technology-risk notices, and the CSA has introduced the Cyber Trust Mark roadmap. These regulatory shifts suggest that security is increasingly expected to be measurable and proven through continuous validation rather than just documented through periodic audits.
Key Takeaways
- Horizon3 is establishing its ASEAN headquarters and a Regional Centre of Excellence in Singapore, supported by investments from EDBI and SG Growth Capital.
- The company’s NodeZero platform provides autonomous security validation, aiming to move organizations from periodic assessments to a continuous "hack-fix-verify" loop.
- The expansion follows a US$250 million Series E funding round in August 2026 that valued Horizon3 at more than US$2 billion.
TechInsyte's Take
In our view, Horizon3’s aggressive expansion into Singapore is a calculated response to the "compliance vs. resilience" gap currently facing Southeast Asian enterprises. As regulatory frameworks like MAS's technology-risk notices evolve, the era of "check-the-box" security is ending. Horizon3 is betting that the market will move toward a model where security posture must be continuously proven through automated, adversarial testing. By securing backing from EDBI and SG Growth Capital, the company is not just entering a market; it is embedding itself into the national cybersecurity fabric of Singapore. This move suggests that the next frontier of cybersecurity competition will be won by platforms that can match the speed of AI-driven attackers. For CISOs, the strategic implication is clear: the focus is shifting from merely identifying vulnerabilities to the continuous, automated verification of remediation efficacy.
Questions & Answers
How does Horizon3's expansion support Singapore's national cybersecurity goals?
Horizon3 is aligning its operations with Singapore’s national cybersecurity priorities, including collaborating on CSA-led initiatives regarding AI for cybersecurity and CII resilience. The company aims to support the digital transformation goals outlined in Singapore's National AI Strategy by providing continuous assurance for digital infrastructures.
What specific technical problem does the NodeZero platform aim to solve for enterprises?
NodeZero addresses the inadequacy of periodic security assessments in the face of AI-driven attacks that can compress timelines from months to hours. The platform autonomously validates attack paths and provides a continuous "hack-fix-verify" loop to ensure that vulnerabilities are not only identified but effectively remediated and retested.
What financial context supports Horizon3's ability to scale in the ASEAN region?
The expansion is supported by new investments from EDBI and SG Growth Capital, following a US$250 million Series E funding round announced in August 2026. This funding round previously established a company valuation of more than US$2 billion, providing the necessary capital for scaling sales and partner operations.
Why is Singapore being used as the primary launchpad for Southeast Asian expansion?
Singapore offers a high concentration of financial institutions, critical infrastructure operators, and regional headquarters. Furthermore, the regulatory environment—characterized by the CSA’s Cyber Trust Mark roadmap and MAS’s tightened technology-risk notices—is driving a regional shift toward measurable, outcomes-based security.
