Don’t Let Overconfidence Undermine Your Cyber Security Defences

You trust your team.

They’re smart, capable, and know better than to click on dodgy links or download unexpected attachments.

They understand that phishing emails are designed to look convincing – precisely to trick people into revealing sensitive information or installing malware.

They’d never fall for that.

Or would they?

Confidence Isn’t Competence

The truth is, confidence doesn’t equal competence when it comes to spotting phishing scams.

Recent research shows that 86% of employees believe they can confidently identify a phishing email – yet over half have fallen victim to a scam in the past. That’s a significant gap between perception and reality.

And that’s exactly what cyber criminals are counting on.

Today’s Threats Are Far from Obvious

Gone are the days of the laughably bad “Nigerian prince” emails. Modern phishing tactics are far more sophisticated, including:

• Emails disguised as messages from banks or trusted suppliers
• Fake invoices that look 100% legitimate
• Internal-looking emails that appear to come from colleagues or management

These scams are crafted to blend in with the day-to-day noise of the inbox — making them harder to spot than ever.

The danger? Employees who are overconfident are less likely to scrutinise emails and more likely to click without thinking.

The Dunning-Kruger Effect in Cyber Security

This is a textbook example of the Dunning-Kruger effect – a psychological bias where people overestimate their knowledge or ability.

When an employee believes they’re immune to scams, they’re less cautious. They might not double-check a link, verify a sender, or question a request that seems unusual. That’s how breaches happen.

So, What Can You Do About It?

The good news? You can reduce the risk – but it takes more than just trusting your team.

Start with a shift in mindset:

Don’t assume knowledge – confirm it.

Run regular phishing awareness training that covers the latest scam tactics and teaches staff how to spot and respond to them.

Encourage open reporting.

Make it easy – and judgment-free – for employees to report suspicious emails. If they feel embarrassed or worried about speaking up, they may stay quiet, and that gives attackers the advantage.

Build a cyber-aware culture.

Cyber security isn’t just a technical issue – it’s a people issue. Create a culture where caution is encouraged, not criticised.

Confidence Is Not a Defence

Even your most tech-savvy team member can be caught off guard. That’s why the smartest approach is to assume a threat is real until proven otherwise – and to act with caution at all times.

Because the moment someone thinks, “I’d never fall for that,” is often the moment they do.
