After more than 30 years in cybersecurity, I’ve seen the industry shift in many ways—but none more important than this: we’re no longer just in the business of prevention. We’re in the business of preparation.

The days of believing a strong perimeter will keep us safe are long gone. Attacks are becoming more frequent, sophisticated, and disruptive. The real question isn’t “Will we be targeted?” It’s “How quickly can we detect, contain, and recover?”

That’s what cyber resilience is all about.

From Defence to Durability

For years, security meant building walls, firewalls, antivirus software, and intrusion prevention systems. These are still important, but they’re no longer enough. No system is impenetrable. At some point, something will get through.

Cyber resilience assumes that reality. It’s about keeping the business running, even in the face of an attack. That means having systems that bounce back fast, people who know how to respond, and plans that are tested and ready to go.

Where traditional security aims to stop threats, resilience focuses on withstanding them.

How the Best Are Getting Ready

Organisations leading the way in resilience are doing a few things differently:

  • They plan for disruption. Not just IT, but also business units. Everyone knows what to do when systems go down or data is compromised.
  • They test regularly. Not just technical defences, but decision-making under pressure, through simulations, tabletop exercises, and dry runs.
  • They invest in recovery. That includes clean backups, redundant systems, and recovery teams that can spring into action without waiting for permission.

It’s not just the security team anymore. Resilience touches every part of the business.

Technology Helps, But It’s Not the Whole Story

There’s a lot of talk about AI and automation in security and yes, they’re valuable tools. They can speed up detection, automate containment, and help reduce downtime. But they’re not silver bullets.

Technology only works if clear processes and well-trained people back it. I’ve seen plenty of sophisticated tools fail—not because they were flawed, but because no one knew how to use them in a real crisis.

Ultimately, resilience is a mindset. It’s about accepting that bad things will happen and being ready to respond effectively when they do.

The Bottom Line

Cyber resilience isn’t a project, it’s a capability. One that needs to be built, maintained, and constantly improved.

In my experience, the organisations that weather attacks best aren’t the ones with the most expensive tech; they’re the ones that have done the hard work of planning, training, and testing. They know who does what, when, and how.

If you haven’t assessed your resilience posture lately, now’s the time. Because when the next incident happens — and it will —your ability to recover will matter more than anything else.
