Cyberattacks don't start with red lights or loud alarms. Often, the first thing that happens is as simple as a misplaced click, a weird connection or an update that was never installed. What's worse is that by the time someone finally notices, the damage has already been done.
The curious (and worrying) thing is that a security incident is not always detected when it happens, let alone from the cybersecurity area. Sometimes the first sign comes from the most unexpected places: a ticket at the help desk, a call to the call center, an alert in the NOC or SOC, or even a frustrated user because he can't log in.
If no one is clear about who should notice these signals first, the company is practically blindfolded.
And that's where a question that very few people ask themselves, but which can make all the difference, comes in: who would detect the first attack in your organization? In this article we're going to talk about why this question matters so much, how it should be approached from a more strategic perspective, and what things are key for your company to detect a threat before it's too late.
Why does it matter so much to detect the first attack?
Cybercriminals act fast. They know what they are looking for and they don't waste time. According to an IBM study, it takes an average of 204 days for companies to discover they have been attacked. Yes, more than six months. That means that a threat can be embedded in your network all that time, moving from one system to another, accessing sensitive information... without anyone noticing. Imagine what can happen in all that time: data theft, espionage, system manipulation, or simply spying on your every move without arousing suspicion.
Because the damage is not only technical, it is also of trust.
And it's not just about fixing servers or changing passwords. The blow can be very hard, both financially and in terms of reputation. According to the Ponemon Institute, a data breach in Latin America costs on average more than 2 million dollars. But the hardest thing to recover is not money, it's trust. When customers feel that their data is no longer safe with you, it is difficult for them to trust you again. And trust, when it is lost, is not fixed with a simple security patch.

Whose responsibility is it to detect the first sign?
The SOC (Security Operations Center) is basically the team that keeps an eye on the company's cybersecurity 24/7. Their job is to detect anything odd that might look like a threat in real time. On the other hand, the NOC (Network Operations Center) makes sure that everything technical (servers, networks, systems) works as it should. If something goes down or there is a failure, they are the first to know. Although they focus on different things, both can be the first barrier to notice that something is wrong.
Now, having a SOC is no guarantee of anything if you don't know what to look for, if you don't have access to the right sources, or if you are simply looking in another direction. It's like having security cameras, but all pointing down an empty hallway, while on the other side, where the intruder actually sneaks in, there isn't one. Detection only works if the team is clear about which indicators to follow, which tools to use and how to interpret the signals. It is no use having the best technology if it is poorly configured or if it is not adapted to the real risks faced by the company. Using a one-size-fits-all solution simply won't work.
And if no one within the company is clear about who should be the first to notice that something is wrong, then they are pretty much in the dark. Detecting an attack is not just about having firewalls or advanced systems; it's also about knowing how to read small signs: a computer behaving strangely, a strange access to a system, errors that start repeating for no apparent reason.
Sometimes, even an ordinary user can notice that something is wrong. But many times, for fear of being scolded or thinking it's their fault, people decide not to say anything. That silence can cost the company valuable hours (or even days) to stop an attack. That's why it's so important that everyone in the organization knows they have a role to play. Taking care of cybersecurity is not just the job of the technical area: everyone can be part of that first line of defense.
A critical vulnerability can also be the first sign of a cyber-attack
Detecting a critical vulnerability (either with a scan or a penetration test) should not be seen as “something to fix later”, but as a warning sign as serious as a confirmed incident. It is not enough to fix the technical glitch and continue business as usual. It is key to ask: has someone already exploited this flaw before we found it? And if there is that possibility, the incident response team should jump into action immediately to check for suspicious activity.
One of the most common mistakes in cybersecurity is to treat vulnerabilities as if they were isolated problems, without considering that they might be connected to unauthorized access. This disconnection is one of the most frequent failures in technology risk management.
And be careful with this: assuming that “if no one has reported anything, everything is fine” can be a big trap. No reporting doesn't mean there are no incidents. In many organizations, people don't know how to report, don't feel comfortable doing it or, even worse, are afraid of getting into trouble. That is why it is so important to have clear channels of communication, to train staff to know how to identify unusual signals and, above all, to foster a culture where those who raise their hand when something goes wrong are not punished.
Many attacks are neither loud nor immediate. They are discreet, move slowly and try to go unnoticed for as long as possible. In more than one real case we have seen, the attacker had been inside the systems for up to eight months before doing anything visible. Every day that goes by without detection, the impact (both in money and reputation) can multiply.
The question any manager should ask is a simple but powerful one: Do we know for sure how we would detect the first sign of an incident? If that answer is not clear and concrete, the biggest risk is not the external attacker, but the internal inability to detect it in time.
Because in cybersecurity, you can't protect what you can't see. And if you don't have a detection system that works beyond the technical area (involving everyone from operations to customer service), then you're not going to react in time. Real resilience doesn't start when the alarm sounds. It starts much earlier, with the ability to see it coming.

Conclusion: Seeing before it's too late changes everything
Detecting the first sign of a cyberattack is not just a technical issue, it's a strategic capability. Sometimes, that first sign is in a strange system behavior, a user complaint, or a seemingly minor alert. The difference between containing in time or regretting the consequences is knowing how to see, interpret and act before the damage is done.
At TecnetOne we understand how crucial it is to anticipate. That's why we offer comprehensive cybersecurity solutions designed to help you prevent, detect and respond quickly and effectively. We have tools and managed services such as our SOC, NOC, backup systems, intelligent monitoring, threat detection and more, so you don't have to wait for the alarm to ring... because many times, when it does, it's already too late.
Our approach is not only technical, it is collaborative: we work with you so that your entire organization is part of an active defense. Because true resilience doesn't start with attack, it starts with preparation.
