The most common security threats in 2025 and how to protect yourself

The digital threat landscape is evolving rapidly, and 2025 is no exception. Businesses across the country need to know what they are facing and how best to protect themselves. Here are the most common threats we see today, and the measures that can make their everyday life safer.

Phishing remains the biggest threat

Phishing is still the most widespread method used by hackers. They exploit human trust to trick employees into clicking links or providing sensitive information. Attacks have become more sophisticated and personalized, making it difficult to distinguish a genuine email from a fake one.

Measures: Make training a regular routine in your company, use technical email filters, and implement two-factor authentication to reduce the damage if someone is tricked. You should also ensure your people receive training throughout the year. We have the solution for that.

We provide a turnkey solution for information security training. As part of the service, we regularly send out short nanolessons every month, ensuring a high completion rate. To test how alert your people are throughout the year, standardized phishing simulations are sent out.

Ransomware

Ransomware attacks have increased in both frequency and severity. Hackers encrypt your data and demand a ransom to restore access. For many businesses, this can mean the end of the road.

Measures: Ensure regular backups are stored offline or in a secure cloud. Update systems continuously and implement network segmentation so that an attack cannot spread unchecked.

Attacks on cloud services

More businesses are moving systems and data to the cloud. This provides flexibility but also opens up new attack surfaces. Poor configuration is one of the biggest risks.

Measures: Maintain control over access management, use strong passwords combined with multi-factor authentication, and ensure you have continuous monitoring of your systems.

Don't have an IT department that can monitor your systems? We recommend partnering with an IT provider who can do it for you. Get in touch with us, and we will help you.

Social engineering

Hackers use psychological tricks to manipulate employees into making mistakes. This could be a phone call from a "supplier," a message from a "colleague," or fake IT support.

Measures: Build a culture where employees feel comfortable asking questions and verifying requests. A simple phone call to the right person can often prevent an attack.

The supply chain

Companies are only as strong as the weakest link in their supply chain. Hackers often target smaller suppliers to gain access to larger targets.

Measures: Set security requirements for suppliers and conduct regular assessments of who has access to your systems and data.

Artificial intelligence as a weapon

AI is not only used for good, but also to develop more sophisticated attacks. This can mean even more credible phishing messages and automated attempts to breach security systems.

Measures: Stay updated on developments and use AI-based security software that can detect patterns humans cannot see.

Security Month is coming to an end, but that doesn't mean we're stopping with our tips. Security is not something that can be paused – it must be built and maintained all year round. New threats emerge constantly, and those who manage to stay afloat are the ones who take regular action. That is why we will continue to share advice, experiences, and knowledge after October, so that both you and your colleagues can feel a little safer in your daily work.

Have a great Security Month!🔐
