Last week, while travelling through my local airport for a trip to Dublin (which is an amazing city to visit), I had one of those unexpected and disruptive experiences. As I joined the queue for security, the fire alarm sounded. Within minutes, the terminal was evacuated, and thousands of people were ushered out into the car park, all wondering whether it was real or just a drill. Before long, we were back inside, queuing again, shoes off, laptops out, belts back in trays. Fortunately, in this instance, there was no actual fire.
The cause was never announced but was probably something harmless, like a faulty sensor, someone vaping in the toilets, or a chef leaving a pan unattended. Whatever triggered it did not matter. The system did exactly what it was designed to do. It detected a potential threat and triggered a response. That response kept people safe.
Now think about your organisation. You would never move staff into a new office and say, “Let’s skip the fire alarms. We’ll deal with flames if we see them.” That would be reckless, uninsurable and completely irresponsible.
Yet every day, many businesses are doing the digital equivalent of exactly that.
No Security Signals Means No Security Response
Far too many organisations are still operating without meaningful cyber threat detection. No Security Operations Centre (SOC). No endpoint detection. No identity protection. No threat intelligence. No incident response plan. Just quiet optimism based on the false belief that “we haven’t had a cyber attack, so we must be fine”.
But here is the uncomfortable truth:
- Cyber threats do not wait for your budget cycle
- Attackers do not care about your size, sector or mission statement
- No organisation is too small or too unimportant to be targeted
If your business operates online, you are exposed. The question is not if you will be targeted. It is when. And more importantly, will you know when it happens?
Most Attacks Go Undetected
According to multiple industry reports, the average cyber breach goes undetected for more than 200 days. That is not because attackers are unbeatable. It is because victims lacked the basics. No alarms. No monitoring. No visibility.
You cannot respond to what you cannot see.
Build Your Security Warning System
Just as modern buildings rely on alarms, smoke detectors and sprinklers, modern organisations need fundamental cyber safety systems in place:
- Essential controls and protection
- Continuous security monitoring
- Real-time threat detection
- Alerting and visibility
- Defined response plans
Without these, businesses are gambling with customer trust, data integrity and operational continuity.
Treat Every Alert as a Potential Threat
At the airport, the reaction was as if the fire was real until proven otherwise. Cyber security should be approached in the same way. Whether it is a suspicious login at 2AM, an unusual data transfer, or a privileged account behaving strangely, every alert deserves investigation. AI and automation now make it possible to prioritise and respond to these at speed and scale.
Sometimes the alert will be harmless. Sometimes it will be noise. But one day, it will not be. If that is the moment your organisation is caught unprepared, the consequences can be severe:
- Operational disruption
- Financial loss
- Regulatory scrutiny
- Legal implications
- Brand damage
- Lost contracts and customers
- In the worst cases, business failure
If you are not detecting threats, or are still relying on manual detection and response, things will slip through, and your organisation is at risk.
Resilience Comes from Security Maturity
Security is not a product. It is a capability you build and continually improve. It requires the right strategy, the right platforms and the right experts behind it.
At Node4, we help organisations build cyber resilience through our structured ACT Against Cyber Risk approach:
- Assess the risk – Gain clarity on vulnerabilities, gaps and priorities
- Consolidate security – Simplify fragmented tools and reduce risk exposure
- Triage and respond – Detect and contain threats quickly with 24/7 SOC expertise
If your business has no “digital fire alarms” in place, that is a risk you no longer need to accept.
