A few years ago, many owners of smaller companies could still think “Cybersecurity? That is a problem for banks, corporations, critical infrastructure operators, large retail networks and technology giants.”
Today, that way of thinking is dangerous. Not because every small company has suddenly become the target of a nation-state attack. The problem is more practical. A modern company, even a relatively small one, is often part of a larger business ecosystem. It serves bigger clients, provides services to regulated industries, uses cloud systems, stores customer data, integrates with payment platforms, sells online, or has access to a client’s internal tools and processes.
And this is exactly where the risk begins the risk many CEOs still do not see.
A cyberattack does not always begin at the headquarters of a large organization. Very often, it begins with a weaker supplier. A small service provider. An external IT partner. A marketing agency with access to advertising accounts. An accounting office. A subcontractor that “only” handles one small part of the process.
For an attacker, it does not matter whether the company has 20, 50 or 200 employees. What matters is access. If a smaller company has access to data, systems, accounts, documents, APIs, customer portals, infrastructure or business processes of a larger organization, then from a cyber-risk perspective it is no longer “small”.
It becomes a side entrance. This is the point that should concern every CEO and business owner. New European regulations no longer treat cybersecurity as a purely technical IT issue. Increasingly, cybersecurity is becoming a matter of risk management, business continuity, board responsibility and supply chain security.
The NIS2 Directive expands cybersecurity obligations across many sectors considered essential or important for the economy and society. This includes energy, transport, healthcare, banking, digital infrastructure, public administration, waste management, manufacturing of certain critical products, postal services, food, chemicals, digital providers and other areas.
But the most important question for smaller companies is different. If our company is not directly covered by NIS2, but we work with a client who is covered by these obligations, can we still pretend this does not affect us?
In practice, more and more often, the answer will be, no. Because a large company, a bank, a critical infrastructure operator, a healthcare organization, a logistics company or a digital service provider will need to look at the cybersecurity posture of its suppliers. They will ask about procedures, incidents, access rights, backups, monitoring, vulnerability management, incident response and evidence that risk is being controlled.
Not because they want to make life harder for smaller partners. Because they themselves will be accountable. This is a fundamental shift.
Cybersecurity is no longer just an “IT cost”.
It is becoming a condition of being a trusted supplier.
A similar direction is visible in DORA, the EU regulation on digital operational resilience for the financial sector. Financial entities are required to manage ICT risk seriously, including the risk created by third-party providers. This means that a technology company, software house, cloud provider, platform operator, integrator, consultant or subcontractor serving the financial sector may face contractual and audit requirements even if it is not a bank itself.
The AI Act also follows a similar logic: technology must be managed through the lens of risk, documentation, responsibility and control. If a company uses AI in processes that affect customers, data, decisions or security, the question is no longer only: “Does it work?”
The question becomes. Can we prove that we understand how it works, what risks it creates and how we control them? Then there is GDPR.
Many companies still make a serious mental mistake here. They think a cyberattack is only a technical issue. But a data breach, loss of access to data, ransomware, misconfigured system or compromised account can very quickly become a legal, reputational and financial problem.
The biggest risk is not always the regulatory fine. Sometimes the bigger risk is the loss of trust. A client may ask:
Did you have monitoring in place?
Did you detect the anomaly earlier?
When did you discover the incident?
Who had access?
Do you have logs?
Can you prove what happened?
Can you show that management knew about the risk and managed it properly?
And this is where many companies may discover an uncomfortable truth.
It is not enough to say: “We have antivirus.”
It is not enough to say: “We have an IT person.”
It is not enough to say: “Nothing has ever happened before.”
The absence of a known incident is not proof of security.
Very often, it is only proof that the company does not know whether something happened.
This is especially important for CEOs.
Modern cybersecurity is not only about buying another tool. It is about being able to answer three strategic questions:
Do we know what is happening in our network?
Can we detect unusual behavior before a problem becomes a crisis?
Can we prove to a client, auditor or regulator what we did and why?
This is where many small and medium-sized companies have their biggest gap.
Not necessarily in technology.
But in awareness. Cybersecurity has become the language of business trust.
Soon, more contracts will include cybersecurity questions. More large clients will require evidence. More boards will ask whether a supplier creates risk. More companies may lose opportunities not because their product is worse, but because they cannot demonstrate digital resilience.
And here is the key point. A small company does not need to build a corporate-level security operations center overnight.
But it must start thinking like a responsible participant in the supply chain.
It needs to know what data it processes. Who has access. How it detects anomalies. How it responds to incidents. How it documents actions. How it secures accounts. How it manages suppliers. How it performs backups. How quickly it can restore operations. And how it can show a client that security is not just a declaration, but a controlled process.
Because in the world of NIS2, DORA, GDPR and the AI Act, the question is no longer:
“Is my company too small to be attacked?”
The real question is:
“Is my company mature enough for a larger client to trust it?”
This is the moment when cybersecurity stops being a technical add-on and becomes a competitive advantage.
Companies that understand this early will be able to use cybersecurity as a sales argument.
Companies that ignore it may only discover the problem when a client requests an audit, a bank asks about digital resilience, an insurer demands procedures, or after an incident someone asks why no one saw the warning signs earlier.
In our view, we are entering a period where the question “Are you secure?” will be replaced by a much harder one:
“Show us the evidence.”
And this is exactly what small and medium-sized companies should start preparing for now.
How do you see it?
Do small companies really understand that they can become the weak link in a larger supply chain?
Are larger organizations already starting to demand concrete cybersecurity evidence from suppliers?
Will cyber resilience become a condition for winning contracts in the coming years?
