Most businesses know what a cyber incident looks like once it becomes visible. Systems go down, information is compromised, customers are affected or operations suddenly stop. By that point, everyone knows there is a problem.
What is harder to see is what was happening in the weeks or months beforehand.
A cyber incident does not always begin with one dramatic event. Risk can build gradually as a business changes. New employees join, others leave or move roles, software is added, suppliers are given access, systems miss updates and more information moves into cloud platforms. Each change may be perfectly reasonable at the time, but over time it can create gaps that nobody is actively looking for.
Access is a good example. Businesses often focus on giving people the access they need to do their jobs, but how often is that access reviewed afterwards? An employee may change roles while keeping old permissions. A former supplier may still have credentials. An administrator account may have broader access than is actually necessary. Nothing appears wrong on the surface, but the exposure is still there.
The same applies to systems and software. An unpatched application may continue working normally. A vulnerability does not necessarily announce itself by causing an outage. The business may only become aware of it when somebody finds a way to exploit it.
Then there is the human side of cyber risk. Phishing and social engineering are designed to look believable. An email may appear to come from a colleague, supplier or senior manager. A request may arrive at exactly the sort of busy moment when someone is less likely to question it. Technology can provide safeguards, but people still need to understand what they are looking for and feel comfortable questioning something that does not seem right.
Third-party relationships add another layer. Most organisations rely on external providers, cloud platforms and connected systems to operate. That makes it important to understand not only how your own environment is protected, but also who else can access it and what happens when those relationships change.
This is why cyber security deserves attention beyond the IT team. For business leaders and boards, the conversation is also about governance, accountability and preparedness.
Who has access to critical systems today? When were security controls last tested rather than simply reviewed? Would employees recognise a realistic attempt to gain access? If an incident happened tomorrow, does everyone know what happens next?
These are relatively simple questions, but the answers can reveal a great deal about how well an organisation understands its cyber exposure.
The objective is not to assume that every unseen vulnerability will become an incident. It is to recognise that a business cannot manage a risk it does not understand. Regular reviews, testing, clear ownership and sensible access controls can help bring some of those hidden risks into view while there is still time to deal with them.
A business can look completely normal from the outside while risk is developing underneath.
The warning signs may not always be obvious and that makes looking for them even more important.
