The modern attack surface has expanded so dramatically that cyber resilience has shifted well beyond the remit of IT departments in an organization to become a national security imperative for economies across Asia.
Organizations today are no longer defending a clearly defined perimeter. Instead, they are responsible for securing a complex web of endpoints, identities, applications, data, and underlying infrastructure, often spread across hybrid and multi-cloud environments.
This interconnectedness means that a single vulnerability can have cascading effects, not just within one organization but across supply chains, critical services, and even national economies.
At the same time, investment in cybersecurity is no longer just about deploying more tools. It requires a clear, ongoing understanding of where vulnerabilities exist and how they evolve. Without this visibility, organizations and governments risk investing heavily in protection while leaving critical gaps exposed.
This challenge is compounded by the rapid adoption of emerging technologies such as AI and cloud platforms, which are driving innovations but also introducing new, often poorly understood risks.
The stakes are higher, and the margin for error is significantly smaller. We discuss this security imperative for nations across Asia with Romanus Prabhu Raymond, Director of Technology, ManageEngine.

Why has cyber resilience become a national security imperative, not just an IT priority?
Romanus: Today, it is no longer sufficient to focus solely on preventing attacks because breaches are increasingly seen as inevitable. Instead, organizations must be prepared to assess their security posture continuously and respond effectively when incidents occur. The ability to detect threats quickly, contain their impact, and restore operations with minimal disruption is now a defining characteristic.
Ultimately, cyber resilience has become a national security imperative because the consequences of failure extend far beyond individual organizations. Disruptions can impact essential services, economic stability, and public trust. Ensuring resilience means maintaining business continuity even when under attack, and it is supported by robust incident management and recovery strategies.
In this environment, resilience is not just about surviving cyber incidents but about sustaining operations and confidence in an increasingly digital society.
Cyber resilience has taken on a far more strategic dimension when viewed through the lens of national security, particularly as geopolitical tensions increasingly play out in cyberspace. For instance, alongside the ongoing hostilities in the Middle East, there has been a parallel surge in cyber operations targeting national infrastructure, which underscores how digital systems have become integral to state stability.
These attacks are not abstract or isolated. They are deliberately aimed at government and critical infrastructure systems such as pipelines, water treatment facilities, and electric grids. The intent is clear: to disrupt the essential services that societies depend on daily.
When cyber-attacks succeed in these areas, the consequences can quickly cascade, affecting access to clean water, reliable electricity, and even transportation networks. What makes this particularly concerning is that such disruptions can occur far from traditional conflict zones, impacting everyday life in ways that feel immediate and local.
Unlike conventional warfare, cyberwarfare is largely invisible, making it harder to detect and identify in real time. This lack of visibility raises the stakes for preparedness. Nations cannot rely solely on prevention; they must assume that some level of compromise is inevitable. In this context, resilience becomes a core pillar of national defense.
The ability to detect intrusions quickly, contain their spread, and restore critical services with minimal downtime is what ultimately determines whether an attack becomes a temporary disruption or a prolonged crisis.
Building this level of resilience requires coordinated efforts across government agencies, private sector operators, and critical infrastructure providers. It is not just about protecting systems but about ensuring the continuity of essential services for citizens under all circumstances.
In that sense, safeguarding critical infrastructure is no longer just a technical challenge. It is fundamental to national security, economic stability, and public trust in an increasingly digital, interconnected world.
