In our latest the latest episode of our NightVision event for our 2026 season, NightDragon Founder and CEO Dave DeWalt sat down with one of the world’s most respected cybersecurity leaders, David Koh, Commissioner and Chief Executive of the Cyber Security Agency of Singapore. Koh, who has led the agency since 2015, shared his insights on the global cyber threat landscape, emerging technologies, and the importance of international collaboration.
Here are some key highlights from their conversation. Tune into the full NightVision discussion below to hear the entire exchange.
The Cyber Threat Landscape Is Intensifying
Koh highlighted that cyber threats are becoming increasingly sophisticated, persistent, and impactful. Over the past few years, state-linked actors and ransomware groups have intensified operations, often targeting critical infrastructure and essential services. Singapore, as a highly connected global hub, has seen advanced persistent threat activity rise fourfold between 2021 and 2024. He emphasized that even small disruptions can quickly escalate, threatening national security, economic trust, and digital infrastructure.
Cybersecurity as a Leadership Priority
Cybersecurity is no longer just a technical problem; it is a strategic imperative. Koh stressed that C-suite leaders and boards must fully understand cyber risks and view them as a critical enabler for business and government operations. Building resilience, fostering a culture of trust, and preparing for incidents are just as important as prevention. In highly connected environments, protecting digital infrastructure is directly tied to maintaining public confidence and economic stability.
Public–Private Partnerships Are Essential
Singapore’s Operation Cyber Guardian showcased the importance of collaboration between government, military, and private-sector organizations. The operation, mounted in response to a sophisticated APT attack, involved multiple agencies and telecommunications providers working together for months. Koh emphasized that no single entity can manage large-scale threats alone; partnerships allow for quicker response, shared expertise, and stronger overall resilience. Effective coordination across civil, military, and private sectors is critical to staying ahead of persistent threats.
International Collaboration Matters
Cyber threats do not respect borders, making global cooperation essential. Koh highlighted initiatives like the Singapore International Cyber Week, which convenes policymakers, academics, industry leaders, and diplomats worldwide. In an era of increasing geopolitical fragmentation, these forums provide opportunities for dialogue, knowledge sharing, and consensus-building. Koh stressed that even when countries or organizations disagree, maintaining communication channels can prevent more serious crises.
AI Is Reshaping Cybersecurity
Artificial intelligence is transforming both attacks and defenses in the cyber domain. Koh noted that attackers are already leveraging AI to create more convincing phishing campaigns, identify vulnerabilities, and accelerate exploit development. On the defensive side, AI can help detect anomalies, correlate weak signals, and automate critical tasks like vulnerability patching. However, defenders often face operational and procedural constraints, which can slow adoption. Bridging this gap is one of the key challenges for cybersecurity professionals today.
Agentic AI as the Next Frontier
Looking ahead, Koh sees agentic AI systems as a major opportunity to augment cybersecurity operations. Acting as “co-pilots” for skilled professionals, AI agents can coordinate complex tasks, identify vulnerabilities, and even assist in automated patching. This approach enhances human capacity, accelerates response times, and could eventually enable self-healing networks. While promising, Koh also cautioned that understanding and monitoring these systems is critical, as their decision-making processes are not always fully transparent.
The Bottom Line
Cybersecurity is entering a new era defined by technological acceleration, global interconnectivity, and increasing sophistication of threats. Koh emphasized that collaboration, innovation, and strategic adoption of AI are essential to maintaining resilience and trust. From public-private partnerships to international dialogue and agentic AI innovation, the global cybersecurity community must adapt rapidly to stay ahead.
