Should the board be responsible for a cyberattack the company failed to detect?
At first, the question may sound harsh. Maybe even unfair. After all, the board does not sit in front of logs, analyse network packets or track every anomaly inside the infrastructure. That is the job of specialists, providers, administrators, procedures and systems.
But let us stop for a moment.
If a company cannot see what is happening inside its own infrastructure, are we really talking only about a technical problem?
Or are we talking about a problem of risk management?
Imagine an ordinary morning. Production is running. Salespeople are sending offers. Accounting is issuing invoices. Customers are placing orders. The board is discussing sales, margins and growth plans. On the surface, everything looks normal.
But somewhere in the background, an old technical account starts behaving differently than usual. A supplier logs in in an unusual way. Data leaves the company in small portions. One application begins communicating with an address it has never contacted before. An employee uses an AI tool outside the official process. Traffic appears in the network that does not yet look like a disaster, but no longer looks like normal business activity either.
Does the company see it?
And if it does not see it, is “we did not know” still an acceptable answer later?
This is exactly the point where cybersecurity stops being only an IT issue and becomes a board-level topic. Not because the CEO should understand every technical detail. Not because the CFO should analyse C2 communication. Not because the company owner should know every network protocol.
But because the board is responsible for the company’s ability to see risk, respond to it and protect business value.
And today, business value is not only machinery, buildings, contracts and cash flow. Business value is customer data, operational continuity, reputation, system availability, partner trust, audit readiness, position in the supply chain and the ability to prove that the company acted responsibly.
So the real question is not: should the board understand cyberattacks?
The real question is, should the board ensure that the company is not blind?
That is a very important difference.
Because the biggest problem after an incident is often not the fact that something happened. In business, risk always exists. A machine can fail. A supplier can disappoint. A customer may not pay. A system can be attacked. The real problem begins when the company cannot answer basic questions.
When did it start? Which systems were affected? Did any data leave the organisation? Was a supplier involved? Is the problem still ongoing? Was it a single signal or part of a wider pattern? Do we have facts, or only assumptions?
During a crisis, “we are checking” is sometimes necessary. But if, after many hours or even days, the company still does not have a clear picture of the situation, the issue is no longer purely technical. It becomes a management problem.
Because management without visibility is not management.
It is hope.
And hope is not a cybersecurity strategy.
Many business owners like to think about cybersecurity as if it were an insurance policy: we bought something, so we are protected. But mature companies do not manage finance only because they have an accountant. They do not manage production only because they have machines. They do not manage quality only because they have a certificate. In each of these areas, they need data, indicators, control, monitoring and a fast response to deviations.
So why do we so often accept the phrase “everything is working for now” when it comes to digital infrastructure?
“Working” does not mean “under control”.
That sentence should be taken especially seriously by medium-sized and industrial companies. These are no longer small organisations that can say the topic does not apply to them. They have customers, suppliers, systems, data, remote access, automation, cloud services, production environments, integrations and often regulatory pressure and expectations from larger business partners.
At the same time, they do not always have large security teams, major security operations centres or corporate-level budgets. And this is where one of the most dangerous gaps appears: the company is already too large to operate based on intuition, but often still not equipped well enough to see its risk in real time.
Can the board of such a company say “This is not our issue”?
In our view, that position will become increasingly difficult to defend.
This is not about looking for someone to blame. It is about maturity. It is about whether the board is asking the right questions. Not “Do we have some security tools?” But “Can we see what is happening inside our infrastructure?” Not “Is someone dealing with it?” But “Do we have a clear picture when something starts to deviate from normal behavior?” Not “Will someone prepare a report after an incident?” But “Can we detect a problem before it becomes public?”
These are the questions that increasingly separate reactive companies from resilient ones.
A reactive company finds out about a problem when a customer calls, a system stops or an auditor asks for documentation. A resilient company sees deviations earlier: unusual behaviour, changes in communication, risky access, unauthorised tools and signals that may indicate the beginning of an incident.
And this brings us to the core issue.
Modern cybersecurity is no longer only about blocking known threats. Increasingly, it is about understanding the behaviour of the environment. Who communicates with whom? What is normal for this specific company? When does supplier access start to look different? When does a technical account behave unusually? When does data transfer stop matching the daily pattern? When do automation, AI or a new application create a risk that was never formally approved?
These are not abstract questions.
They are questions about business continuity.
Because a cyberattack does not always stop a company immediately. Sometimes it first collects information. Tests boundaries. Moves inside the infrastructure. Searches for data. Checks access. Waits. And during all this time, the company may continue operating normally and feel that nothing is happening.
The most dangerous incident is not always the one you see immediately.
The most dangerous incident is the one that looks like normal work for a long time.
That is why companies need a new layer of communication between technology and the board. Not the language of hundreds of alerts. Not the language of fear. Not the language of technical abbreviations that mean nothing to management. What is needed is the language of facts: what changed, why it matters, what the potential impact is, whether action is required, whether there is evidence and how quickly a decision can be made.
This is the gap NetSenX is built to close.
Not as another element that creates more noise, but as a layer of visibility and network behaviour monitoring for companies that want to better understand what is happening inside their digital environment. The system analyses communication patterns and helps detect anomalies, unusual behaviour, Shadow IT, Shadow AI, lateral movement, C2 communication, supplier-related risks and potential data exfiltration before small signals become serious incidents.
But the most important thing is not detection itself.
The most important thing is helping the company move faster from uncertainty to decision.
Because in practice, the board does not need to know everything. It needs to know early enough, clearly enough and reliably enough not to manage through fog.
Does this mean the board should be responsible for every cyberattack? No. That would be too simple and unfair.
But the board will increasingly have to answer whether the company was prepared. Whether it had visibility. Whether it could detect deviations. Whether it had a response process. Whether it had evidence. Whether it could show customers, partners, insurers or regulators that it was not operating blindly.
That difference is enormous.
No company can honestly promise that it will never be attacked. But every company can ask a much more important question, if something starts happening, will we see it early enough?
That is now one of the most important management questions in cybersecurity.
And this is why the topic of board responsibility will keep coming back. Not as a scare tactic, but as a consequence of a digital economy in which every company has become partly a technology company even if it still manufactures, transports, sells, treats, designs or serves customers.
In the end, one question remains for every CEO, CFO and business owner:
If an incident happens tomorrow, will you be able to say, “we saw the signals and responded”, or only, “we did not know”?
Should responsibility for an undetected incident end with IT, or should it begin at the level of board risk management? Where do you think the line is between “it could not have been predicted” and “the company did not have enough visibility”?
Someone in your network may need to ask today whether their company is truly managing cyber risk or simply believing that everything is under control.
