If there’s one thing the current threat landscape has made clear, it’s that prevention and response readiness aren’t mutually exclusive; instead, you need both. Preventative controls are essential, but they’re never a guarantee of protection.

Data breaches are happening more often than organisations would like to admit. It only takes one click – and if your response capability isn’t up to speed, you could be dealing with a potential catastrophe. Your incident response capability needs to kick in immediately, isolating and containing the threat before it can propagate through the environment.

To balance prevention and response, one shouldn’t be prioritised over the other, but response is becoming increasingly critical in determining outcomes.

Ideally, organisations should be running simulations monthly, especially against critical applications. It keeps risk top of mind and exposes whether your processes are efficient enough. Many organisations work towards a four-hour response and resolution window. That means isolating the threat, stabilising the environment and resuming business operations within that timeframe. If you don’t practise, you won’t perform when it matters.

Ransomware attacks have evolved rapidly, and they no longer fit neatly into categories like malware, worms or classic ransomware. Today, they’re a combination of techniques aimed at locking organisations out of their own information.

The user remains one of the primary attack vectors, because threats are delivered in ways that appear completely legitimate. Attackers begin with credential harvesting. Once they gain access, ransomware may follow, but it’s rarely the first or only stage. Platforms exist that scrape publicly available information from across the internet and social media, building profiles on individuals and organisations. Threat actors then use this information to impersonate people convincingly.

Corporate networks are generally secure, so attackers often target users on mobile devices, where controls are weaker. A seemingly innocent WhatsApp link can lead to credentials being exposed. The moment something seems out of character, it’s critical to pause, verify and close the loop.

The key lesson here: Ransomware highlights why preparedness and response matter more than prevention alone. Even the most advanced preventative controls can fail, but an organisation that is resilient, well-practised and ready to respond can isolate the threat quickly, contain it and resume normal business operations.

A mature ransomware resilience strategy is built on a governance- driven, risk-based approach. It requires due diligence across the organisation, not just within IT. That includes governance checkpoints, policy reviews and alignment with recognised frameworks and standards. It’s about becoming data-centric, understanding where your data resides and ensuring that everything supporting it is secure.

That means hardened infrastructure, closed ports, patched operating systems and effective vulnerability management to keep systems aligned with best practice and benchmark standards, but it also means a culture of resilience.

Mature organisations understand the importance of business continuity planning, disaster recovery, regular simulations and ongoing policy reviews. Because resilience isn’t built in a single layer, cybersecurity must put equal focus on people, processes and technology.

The single shift that organisations need to make: Organisations must start thinking in terms of prevention and preparedness. Readiness is what determines whether an incident becomes a disruption or a full-blown crisis.
