Summary: Cybersecurity doesn’t have to be expensive or complex. Start with an audit to know your weakest points, close critical gaps, train your employees and test your defenses. On average, a Flemish SME invests €5,000 to €15,000 in the first year, and with VLAIO grants, the government pays up to half.

Cybersecurity feels overwhelming if it’s not your business. Dozens of acronyms, hundreds of possible measures and vendors all claiming their solution is indispensable. Yet the reality is simpler than it seems. The VLAIO Cybersecurity Barometer 2024 shows that while 45.8% of Flemish companies were victims of a cyberattack in 2024, the most affected companies often had not implemented even the basic measures. This article gives you a concrete roadmap to take your SME from zero to basic protection, including budget indications and grant opportunities.

Why cybersecurity is no longer a luxury for Flemish SMEs

The perception that only large companies get hacked is no longer true. SMEs are even a more attractive target for cybercriminals: they have valuable company data but usually have less protection than multinationals. Automated attacks via phishing and ransomware make no distinction. One vulnerability, one human error or one misconfiguration is enough to compromise systems.

The numbers for Flanders speak for themselves. Almost half of Flemish companies faced a cyber attack in 2024. In 1 in 10, this led to effective damage: data breaches, financial losses or damage to reputation. At the same time, 71% of entrepreneurs think they are well protected, while practice shows that procedures and measures, especially for SMEs, are often inadequate. Only 23.4% of Flemish companies have a formal cybersecurity policy document.

On top of that comes legislation. Since Oct. 18, 2024, Belgium’s NIS2 law has been in effect. Medium-sized companies (50 to 250 employees) in critical sectors fall under this regulation and must demonstrably implement security measures. Directors are personally liable for negligence, with fines of up to 2% of annual global turnover. A comprehensive overview of all NIS2 obligations can be found in our NIS2 guide for Flemish companies.

The roadmap: in five stages from zero to basic protection

An effective cybersecurity approach does not have to be done all at once. The roadmap below spreads the effort over three to six months, allowing you to complete each phase before moving on to the next.

Phase 1: know where you stand (month 1)

Everything starts with understanding. You can only protect what you know. A cybersecurity audit maps your entire IT environment: what systems are you running, where are the weakest points, and which risks are the highest priority? The result is not a thick report gathering dust, but a concrete roadmap with quick wins and structural improvements.

For SMEs covered by NIS2, the Belgian CyberFundamentals (CyFun) framework is an excellent starting point. The CCB offers free self-assessment tools to help you assess your current level. You can read more about CyFun and the different levels here.

Investment: market range €5,000 to €15,000 for an audit, depending on the size of your organization. After VLAIO grant, you will pay 50% to 65% less.

Phase 2: close the critical gaps (months 1 to 3)

The audit produces a priority list. The top five items are typically the same in most SMEs:

Activate multi-factor authentication (MFA) on all remote access points and cloud applications. This is the most effective measure against stolen passwords, and account compromise doubled in 2025 from the previous year.

Testing and strengthening backups. Not just make, but restore effectively. The 3-2-1-1 rule is the standard: three copies of your data, on two different media, one offsite and one immutable. Learn how ransomware groups specifically target your backups in our article on ransomware 2.0.

Implement network segmentation so that an attacker who enters does not have immediate access to your entire network.

Structuring software updates and patch management. The average time between disclosure of a vulnerability and its exploitation has dropped to less than five days.

Move from traditional antivirus to Endpoint Detection & Response (EDR), a technology that monitors suspicious behavior in real time and can intervene automatically.

Investment: many of these measures are organizational and primarily require time from your IT team or IT partner. Technical investments such as EDR software typically cost €6 to €12 per user per month.

Phase 3: train your people (months 2 to 4)

Technology captures much, but humans remain the first line of defense. The VLAIO Barometer 2024 shows that 42.8% of companies consider insufficient training and awareness among staff to be the biggest cyber risk.

An effective security awareness program combines short, regular training sessions (monthly, no more than five minutes per session) with simulated attacks. A phishing simulation acts as a baseline measurement: how many employees click on a suspicious link? The average click rate in an initial simulation is between 20% and 30%. After 12 months of training, that drops to less than 5%.

Equally important: encourage a reporting culture. Employees who report suspicious matters without fear of reprimand are your strongest detection mechanism. One quick report of a clicked link can make the difference between a local incident and a company-wide disaster.

Investment: awareness platforms cost an average of €2,000 to €4,500 per year. Training is subsidizable through the SME portfolio.

Phase 4: test your defenses (months 3 to 6)

After the audit, quick wins and awareness training, it’s time to validate your defenses. A penetration test (pen test) simulates a real attack on your systems. Where the audit assesses your security, a pen test proves whether an attacker can get through effectively.

For most SMEs, an annual infrastructure pen test on the external perimeter is sufficient, supplemented by a test after any major change in the IT environment. Do you have a web application or customer portal? Then an application pen test is also recommended.

Investment: market range €3,000 to €8,000 for an infrastructure pen test, €4,000 to €12,000 for a web app pen test. After subsidy, a small business pays up to 45% less.

Phase 5: structural assurance (ongoing)

Cybersecurity is not a project with an end date, but an ongoing process. In this phase, you embed the measures from the previous phases into your operations.

Choose a compliance framework as a guide. For most Flemish SMEs, CyFun Basic is the logical entry level. Our comparison between ISO 27001 and CyberFundamentals tells you which framework best suits your situation.

Repeat the audit annually to measure whether your security is improving. Hold awareness training on an ongoing basis. Test your backup recovery procedure at least quarterly. And set up a simple incident response plan with contact information for your IT partner, insurer and the CCB so you don’t have to improvise in the event of an incident.

Does your company have cyber insurance? If so, insurers will be setting high standards for your level of security in 2026. MFA, an incident response plan, EDR and regular pen tests are now non-negotiable underwriting requirements.

What does cybersecurity cost for an SME?

The total investment in the first year depends on your starting position and company size. For an SME with 50 to 100 employees, a realistic budget indication:

A cybersecurity audit as a starting point: €5,000 to €15,000. Technical measures such as EDR software, password management and adjustments to your network: €3,000 to €8,000. An awareness platform with phishing simulations: €2,000 to €4,500 per year. An annual pen test: €3,000 to €8,000. Total first year: €13,000 to €35,500, depending on scope and complexity.

That seems like a lot, but contrast it with the cost of an incident. The average cost of a data breach is $4.44 million worldwide, according to the IBM Cost of a Data Breach Report 2025. For a Flemish SME, a ransomware attack realistically lies at €20,000 to €200,000 in direct damage: downtime, technical recovery, legal fees and lost revenue. How a Flemish producer avoided an attack of more than €100,000 thanks to a proactive approach, read our case study.

Flemish subsidies that make it affordable

The Flemish government wants SMEs to invest in cybersecurity and offers two powerful grant instruments.

VLAIO Cybersecurity Improvement Projects are the most comprehensive option. The government covers 50% of the cost (35% for companies too large for the SME definition but covered by NIS2). Three packages are available: START (€7,100 to €11,900) for a baseline measurement and action plan, MEDIUM (€16,600 to €28,600) with active guidance on troubleshooting, and PLUS (€26,500 to €39,900) for an intensive track including implementation support. Full details on the improvement pathways can be found in our VLAIO article.

The SME portfolio has been reserved exclusively for cybersecurity advice and training since February 1, 2026. Small companies (less than 50 employees) receive 45% subsidy, medium-sized companies (50 to 249 employees) 35%, with a maximum of €7,500 per year.

Calculation example. A medium-sized SME commissions a €8,000 cybersecurity audit and then purchases a €3,500 awareness training package. Through the SME portfolio, the company receives a 35% subsidy on both services: €4,025 back. The effective investment drops from €11,500 to €7,475. If you combine this with a START improvement program, VLAIO pays an additional 50% of €8,500 (the average START rate): another €4,250 subsidy. Total savings: more than €8,000.

The five most common cybersecurity mistakes for SMEs

“Our IT company will take care of that.” Your IT partner makes sure systems work. That is not the same as making sure they are secure. Make explicit agreements about who is responsible for security, monitoring and patch management. Trust is good, but verifying is better.

Once a year, an awareness session and done. One-time training sessions have been shown to have little effect. Frequency and repetition are what works. Monthly short sessions combined with simulated phishing attacks make all the difference.

Backing up but never testing. 89.7% of Flemish companies make backups, but a fraction regularly test whether the recovery process is actually working. Ransomware groups know this and specifically target backup systems.

“We are too small to be hacked.” That very attitude makes SMEs vulnerable. Automated attacks scan the Internet looking for vulnerabilities, regardless of the size of the company. Moreover, SMEs are increasingly being used as a springboard to attack larger companies in the supply chain.

Approach cybersecurity as a one-off project. An audit and a pen test are not an end point but a starting point. Without ongoing attention to updates, training and monitoring, your measures become obsolete faster than you think.

Frequently asked questions about cybersecurity for SMEs

Does my SME need to be NIS2 compliant?

It depends on your sector and company size. Companies with 50 or more employees operating in sectors such as energy, transport, healthcare, digital infrastructure or manufacturing fall under the Belgian NIS2 law. Registration with the CCB has been mandatory since March 2025. In doubt? Our NIS2 roadmap will help you determine quickly.

How much should an SME invest in cybersecurity?

The VLAIO Barometer 2024 shows that Flemish companies spend an average of 22% of their total IT budget on cybersecurity. For an SME with 50 to 100 employees, this translates into an indicative investment of €13,000 to €35,500 in the first year, depending on the starting position. With VLAIO grants, that investment can drop by up to 50%.

What is the difference between a cybersecurity audit and a pen test?

An audit assesses your entire security status: policies, processes, technical configuration and compliance. The result is a prioritized roadmap. A pen test is a targeted technical test that attempts to actually exploit vulnerabilities in a specific system or network. The audit tells you where the risks are, the pen test proves whether an attacker can get through. Both complement each other.

Can I combine VLAIO grants?

Yes. You can combine the SME Portfolio (45% or 35% subsidy on cybersecurity advice) and the VLAIO Cybersecurity Improvement Pathways (50% subsidy), as long as you don’t duplicate the same costs. In practice, for example, you fund the audit through the improvement track and the awareness training through the SME portfolio.

How quickly can my company achieve basic protection?

With a structured approach, an average SME reaches a solid baseline within three to six months. You will deliver the first quick wins, such as MFA activation and strengthening backups, within the first month. The full cycle from audit to structural assurance through a compliance framework typically takes six to 12 months.

Is cybersecurity also relevant to sectors outside NIS2?

Absolutely. The NIS2 Act is a legal lower limit for certain industries, but cyber attacks make no distinction. Any SME with digital systems, customer data or online accessibility is at risk. Moreover, more and more clients, insurers and banks are imposing cybersecurity requirements on their suppliers, regardless of sector. Read how this affects the healthcare sector and the manufacturing industry.
