Security Awareness Training: How to Make Your Staff Cyber-Aware

Security Awareness Training: How to Make Your Staff Cyber-Aware

95% of all successful cyberattacks start with human error. Not a technical vulnerability, but an employee who clicks the wrong link, shares a password or opens a suspicious attachment. That makes security awareness training the most cost-effective investment in cybersecurity a business can make. In this guide you'll learn how to set up an effective training programme and turn your team from the weakest link into your strongest line of defence.

Key takeaways (TL;DR)

• 95% of all data breaches are caused by human error. Technology alone is not enough.
• Businesses with security awareness training experience 70% fewer successful phishing attacks.
• The average cost of a data breach for an SME is €95,000-165,000. Training costs a fraction of that.
• One-off training doesn't work: effective awareness requires ongoing repetition, at least every quarter.
• NIS2 makes awareness training mandatory for many businesses from mid-2026.
• Phishing simulations cut the click rate from an average of 32% to under 5% within 12 months.
• The ROI of awareness training is 5-10x the investment, thanks to the incidents it prevents.

Why Security Awareness Training Is Essential

You can deploy the best firewalls, EDR solutions and encryption, but if an employee types their password into a phishing site, all of it is worthless. People are, and will remain, the most important factor in cybersecurity.

Threats are becoming ever more sophisticated. With the rise of AI-driven phishing, attacks are barely distinguishable from genuine communication. AI writes flawless Dutch, copies writing styles and creates convincing scenarios. Only trained employees can spot the subtle signs.

Remote working increases the risk. Hybrid working means employees are working outside the secure office network, on their own devices and over public Wi-Fi. Securing hybrid working starts with security-conscious staff.

Regulation demands it. The NIS2 Directive, which is being written into Dutch law in mid-2026, requires organisations to train their employees in cybersecurity. It is no longer a nice-to-have but a legal obligation.

The 7 Biggest Risks Training Addresses

1. Phishing and spear phishing

Phishing remains the number one attack method. Every day, employees receive emails that appear to come from familiar senders: colleagues, suppliers or customers. Email security with SPF, DKIM and DMARC helps on the technical side, but the last line of defence is the employee who receives the email.

What training teaches: recognising suspicious features, checking URLs before you click, not opening unexpected attachments and reporting anything doubtful to IT.

2. Social engineering

Attackers phone employees, posing as IT support, a supplier or even the managing director. They play on trust, urgency and helpfulness to gain access to systems or information.

What training teaches: following verification procedures, never sharing passwords by phone or chat, and always calling back on a known number to check.

3. Weak passwords

Despite all the warnings, employees still use weak passwords, reuse the same password across multiple accounts or write them on sticky notes. MFA catches a lot, but good password hygiene remains the foundation.

What training teaches: using strong passwords or passphrases, using a password manager and never reusing passwords.

4. Working insecurely on public networks

Employees working in a coffee shop, on a train or in a hotel connect to unsecured Wi-Fi networks. This opens the door to man-in-the-middle attacks in which traffic is intercepted.

What training teaches: always using a VPN on public networks, postponing sensitive tasks until you're on a secure network, and using a mobile hotspot as an alternative.

5. USB devices and physical threats

A USB stick in the car park, an unattended laptop in a café or a visitor walking around the office unaccompanied: physical threats are often underestimated.

What training teaches: never plugging in unknown USB devices, locking your device when you leave your desk and always accompanying visitors.

6. Shadow IT

Employees using their own tools and cloud services without IT's approval, from free file-sharing services to AI tools fed with company data. This creates hidden risks that fall outside IT's view.

What training teaches: why using approved tools matters, how to request new tools and what risks shadow IT brings.

7. Careless handling of data

Emailing sensitive documents to personal addresses, sharing confidential information over unsecured channels or leaving data on shared printers. Small lapses in attention can lead to major data breaches.

What training teaches: understanding data classification, sharing files securely through approved channels and handling confidential information with care.

How Do You Set Up an Effective Training Programme?

An effective security awareness programme is more than an annual presentation. It is an ongoing process that drives behavioural change.

Step 1: Establish a baseline

Start with a baseline measurement so you know where you stand. Run a phishing simulation without prior warning. How many employees click the test link? That percentage is your starting point.

Typical results from a first measurement:

• 25-35% click the phishing link
• 10-15% actually enter their details
• Fewer than 20% report the suspicious email to IT

Step 2: Basic training for everyone

Start with interactive basic training that covers the fundamentals: recognising phishing, secure passwords, a clean desk policy and reporting procedures. Make it practical and relevant with examples from your own industry.

Duration: 60-90 minutes Format: an interactive workshop, not just a presentation Frequency: when people join and repeated annually

Step 3: Ongoing phishing simulations

Schedule monthly phishing simulations of increasing difficulty. Start with recognisable attempts and gradually increase the realism. Employees who click receive educational feedback straight away.

After 12 months of consistent testing, the average click rate falls from 30% to under 5%.

Step 4: Short micro-learning

Every two weeks, send a short tip or update that takes no more than 3 minutes to read. Current threats, practical tips or a quiz question. This keeps security top of mind without overloading people.

Step 5: Role-specific training

Not every employee faces the same risks. Finance staff are more susceptible to CEO fraud, HR receives lots of external attachments and IT administrators are targets for advanced attacks. Offer in-depth training per department.

Step 6: Measure, report and improve

Track the following KPIs over time:

• Phishing click rate (target: below 5%)
• Reporting rate (target: above 70%)
• Average time to report (target: under 5 minutes)
• Repeat clickers (target: below 2%)

Report to management monthly and adjust the programme based on the results.

What Does Security Awareness Training Cost?

Costs vary depending on size and approach.

Compare this with the average cost of a data breach for an SME: €95,000-165,000. The investment in training is minimal compared with the risk it covers.

The Role of Technology Alongside Training

Security awareness training doesn't stand on its own. It works best in combination with technical measures.

MFA (Multi-Factor Authentication) neutralises stolen passwords. Even if an employee enters their password on a phishing site, the attacker can't log in without the second factor.

Email filtering blocks most phishing emails before they reach the inbox. But no filter is 100% effective, which makes the trained employee the last line of defence.

Endpoint Detection & Response detects suspicious behaviour on workstations and servers. If an employee does click a malicious link, EDR can limit the damage.

Zero Trust limits the impact of compromised accounts by applying the principle of least privilege.

NIS2 and Awareness Training

The NIS2 Directive explicitly states that organisations must ensure "cyber awareness" among their employees. This includes:

• Regular training on current cyber threats
• Awareness of the role every employee plays in cybersecurity
• Documentation of the training programme and its results
• Demonstrable effectiveness through measurable improvements

Failing to meet these requirements can lead to fines of up to €10 million or 2% of annual turnover. That makes awareness training not only sensible but legally necessary.

Frequently Asked Questions

How often should you run security awareness training?

Annual training is the bare minimum, but it isn't enough for real behavioural change. Best practice is a combination of quarterly training, monthly phishing simulations and fortnightly micro-learning. This keeps security permanently top of mind.

Does security awareness training really work?

Yes, the figures are convincing. Businesses that run a structured awareness programme see their phishing click rate fall from 30% to below 5%. The number of security incidents drops by 60-70%. On average, the investment pays for itself 5-10 times over.

How do I convince management of its importance?

Present it as risk management with concrete figures: the average cost of a data breach (€95,000-165,000) versus the cost of training (€5-20 per employee per month). Add the NIS2 obligation and the business case writes itself.

Is online training enough, or does it need to be live?

A combination works best. Online training offers flexibility and scalability, while live workshops create more interaction and engagement. Start with a live kick-off session and supplement it with ongoing online modules and simulations.

Do directors and managers need training too?

Absolutely. Management is in fact a prime target for attackers (whaling). It also sends a powerful signal when the leadership takes part: cybersecurity is a shared responsibility.

What do I do with employees who keep failing phishing tests?

Punishment backfires. Offer extra training and support. Consider tailored simulations that match their specific work. In some cases, a buddy system in which a more security-aware colleague keeps an eye out can help.
