“It Won’t Happen to Us…” – Five Common Misconceptions in IT Security

“We’re too small to be hacked.” – Have you thought that too? Many SMEs have a false sense of security. Unfortunately, this often backfires: cybercriminals don’t discriminate by company size; on the contrary, small businesses with minimal protection are easy prey for automated mass attacks. In this article, we debunk five common misconceptions about IT security and show why they are dangerous.

The Five Most Dangerous Cybersecurity Myths

Misconception 1: “We don’t have anything that would interest hackers”

Every company has something valuable: data, customer information, money, or simply computing power. Attackers steal personal data to commit identity theft, or use your compromised computers as part of a botnet. Even if your business is local and small – automated malware scans the internet for every vulnerable weakness. SMEs are usually attacked not in a targeted way, but broadly and automatically. No internet connection goes unnoticed.

Misconception 2: “IT security is a matter for the IT department, not management”

In small companies, there is often no IT department – and yet someone must take the reins. Cybersecurity is a leadership task because a major incident can be existentially threatening to the company. Company management must assess risks, allocate budgets, and approve measures. In an emergency, they may also be liable for failures. The BSI emphasizes that responsibility for information security always lies with company leadership. There’s no point in delegating this topic away.

Misconception 3: “Our antivirus software and firewall are enough”

Basic protection like antivirus programs and firewalls is important – but today it is far from sufficient. Many attacks bypass technical defenses by, for example, exploiting people as a vulnerability (phishing emails, social engineering) or using new malware that virus scanners don’t yet recognize. Moreover, such protection programs must be kept up to date and correctly configured. An outdated virus scanner provides deceptive security. Additional measures such as backups, access restrictions, and employee training are indispensable.

Misconception 4: “Cyber insurance? Then we’re carefree”

Cyber insurance can be very helpful in the event of damage. But it is not a substitute for preventive security. Many policies make coverage conditional on basic protective measures having been maintained – those who act negligently may get nothing. Furthermore, insurance cannot compensate for intangible damages such as the loss of customer trust. Insurance covers the financial side, but does not prevent the attack itself.

Misconception 5: “IT security only costs money and brings no added value”

Yes, security measures cost time, effort, and money. But a successful cyberattack costs far more – financially and reputationally. According to studies, cyberattacks and sabotage cost the German economy an estimated €267 billion per year. Preventive measures such as regular updates or awareness training are often low-cost but can prevent millions in damages. Moreover, more and more business partners are requiring evidence of IT security (e.g., certifications) – security is becoming a competitive advantage.

From False Assumptions to Effective Protection

Practical tip: Go through these five points in discussion with your leadership team. Where do you catch yourself thinking similarly? Consciously correct these misconceptions – they represent “dangerous half-knowledge.” By debunking these myths, you create the foundation for a realistic risk assessment and effective protective strategies.
