The Five Cybersecurity Questions Every Critical Organisation Should Be Asking in 2026

What has changed is not only the scale of cyber threat activity, but the convergence of operational technology, cloud services, remote connectivity, supply chain dependency and geopolitical instability. Many organisations now operate highly interconnected environments where disruption in one domain rapidly affects another. As a result, leadership teams increasingly need to think beyond isolated security tooling and instead consider how cyber resilience is engineered across the whole enterprise lifecycle.

The challenge for many organisations is not necessarily understanding that cyber risk exists, but understanding where to prioritise investment, how to demonstrate resilience, and how to build operationally realistic security programmes that can function in live, highly regulated environments.

Below are five strategic issues organisations should now be considering.

1. Is Cybersecurity Embedded Into Operational Design - Or Added Afterwards?

One of the most persistent challenges across both enterprise IT and operational environments is that cybersecurity is often implemented reactively. Security controls are introduced after systems have already been designed, deployed or integrated.

This becomes particularly problematic in CNI environments where systems may remain operational for decades, where downtime is costly, and where changes can introduce safety or availability risks.

Increasingly, regulators and assurance bodies are moving toward “secure by design” expectations. Organisations are being asked to demonstrate not simply that controls exist, but that resilience, governance and assurance have been considered throughout the system lifecycle.

This is especially important in sectors such as energy, transport, defence and government where complex supplier ecosystems and legacy technology create long-term exposure.

The strategic question for many organisations is therefore no longer:

“How do we secure this system?”

but instead:

“How do we ensure security engineering becomes part of how systems are conceived, procured, integrated and operated?”

That shift has implications for governance, procurement, architecture, assurance and operational culture.

2. Do We Truly Understand Our Operational Technology Risk Exposure?

Operational Technology (OT) environments have become one of the most significant areas of cyber focus globally. Industrial control systems, distributed sensing technologies, remote operational access and interconnected supply chains have expanded the attack surface for critical operations.

However, many organisations still lack complete visibility of their OT estate.

In practice, this often means organisations do not fully understand:

• which assets are exposed,
• how systems communicate,
• where privileged access exists,
• what operational dependencies are present,
• or how cyber compromise could translate into physical or operational consequences.

This becomes increasingly important as IT and OT environments converge.

Organisations now need to move beyond isolated threat detection and instead understand exposure across interconnected assets, prioritise risk by operational consequence and build resilience before disruption occurs.

A recurring challenge in OT security is balancing operational continuity with security improvement. Security programmes that work in enterprise IT environments cannot simply be copied into industrial environments without understanding operational realities.

This is why baseline understanding matters. Asset discovery, behavioural baselining, governance mapping and operational-context analysis increasingly form the foundation of OT resilience strategies.

For many boards and operators, the strategic issue is therefore not simply whether they have OT security tools deployed, but whether they genuinely understand how cyber risk propagates through operational processes.

3. Is Our Cryptographic Strategy Ready for Long-Term Change?

Cryptography has historically operated in the background of enterprise security architecture. Increasingly, however, it is becoming a strategic resilience issue as it underpins the security of organisations.

There are several reasons for this.

First, organisations are becoming more dependent on machine identities, certificates, secure connectivity and distributed trust models. Second, regulatory scrutiny around assurance, sovereignty and data protection is increasing. Third, many organisations are beginning to assess the implications of post-quantum cryptography migration.

The challenge is that cryptographic estates are often poorly understood. Certificates, keys, trust chains and embedded cryptographic dependencies may exist across thousands of systems, applications, devices and suppliers.

Without visibility and governance, cryptographic modernisation becomes extremely difficult.

Importantly, post-quantum migration is not simply a technology refresh exercise. It is an enterprise transformation issue that affects architecture, procurement, interoperability, lifecycle management and assurance.

The key question for organisations is not whether post-quantum transition will eventually matter, but whether enough visibility exists today to understand where future exposure resides.

4. Can Our Security Operations Function Keep Pace With Modern Threat Activity?

Despite heavy investment in security monitoring over the past decade, operational effectiveness remains inconsistent. 

The problem is rarely the absence of tooling alone. More commonly, organisations struggle with:

• fragmented visibility,
• alert overload,
• unclear operational processes,
• lack of skilled analysts,
• inconsistent maturity,
• or insufficient integration between detection and operational response.

At the same time, adversaries are accelerating their operational tempo, automation, and targeting sophistication. 

This has created renewed focus on operational maturity rather than isolated technical controls.

Increasingly, organisations are recognising that effective security operations require:

• operational integration,
• clear governance,
• threat-informed prioritisation,
• and alignment between business risk and technical response.

The strategic challenge therefore becomes determining whether the organisation’s current operating model can realistically detect, prioritise and respond to modern threats at sufficient speed and scale.

5. Are We Building Resilience - Or Simply Adding Security Products?

One of the most important shifts occurring across cybersecurity is the movement away from product-centric thinking toward resilience-centric thinking.

Historically, organisations often approached cybersecurity as a procurement problem:

• deploy another tool,
• add another platform,
• implement another control.

However, resilience failures rarely occur because a single technology was absent. They more commonly occur because:

• processes were fragmented,
• teams were unprepared,
• governance was weak,
• dependencies were misunderstood,
• or operational coordination failed during disruption.

This is why resilience testing, exercising, training and operational validation are becoming increasingly important.

Increasingly, organisations need environments where technologies, operational processes and human response can be tested together under realistic conditions — without introducing risk into live operational systems.

Resilience therefore becomes less about individual security controls and more about whether the organisation can:

• continue operating during disruption,
• recover safely,
• maintain decision-making,
• and adapt under pressure.

That is fundamentally a leadership and operational challenge as much as a cybersecurity one.

Conclusion

Cybersecurity strategy is increasingly converging with operational resilience, governance and long-term organisational trust.

For critical organisations, the challenge is no longer simply deploying additional security technologies. It is understanding how to:

• engineer resilience into complex environments,
• secure interconnected operational ecosystems,
• modernise cryptographic trust,
• improve operational detection and response,
• and validate resilience under real-world conditions.

As regulatory expectations, operational interconnectivity and cyber-physical risks continue to increase, organisations that treat cybersecurity as a strategic resilience discipline — rather than a standalone technical function — are likely to be better positioned to manage both current and future risk.
