Cybersecurity challenges and trends in 2025: expert predictions and technology trends

Our yearly series of blog articles aims to gather predictions and ideas from leading vendors, independent analysts and consultants on cybersecurity trends for the upcoming year. In 2025 we will also be presenting this extensive overview, providing insights into the expected threats, technology trends and practical advice on how to prepare.

As we enter 2025, the cybersecurity landscape is evolving. The emergence of new technologies, changing attack methods and tightening global regulations are all impacting how companies and individual users prepare for the threats of the future. Below, I detail the predictions and recommendations of leading industry players and share my personal views on what we can learn from these predictions.

Expected threats in 2025: the changing threat landscape

AI-based attacks: hand in hand with technology... or against it?

As artificial intelligence (AI) becomes more available, attackers are beginning to exploit its potential. According to Palo Alto Networks, AI-based attacks pose a particularly high risk in automated phishing campaigns and the distribution of fake content. These so-called "deepfake" attacks can threaten not only corporate systems, but also political and social stability.

Personally, I think that AI will probably act as a double-edged sword: those who adapt and build in defenses earlier will have a much better chance of winning.

Supply chain attacks and geopolitical conflicts

Trend Micro's annual report warns that attacks against supply chains remain one of the biggest threats, particularly in critical infrastructure such as energy and water utilities. These attacks are becoming increasingly sophisticated and can cause significant damage on a global scale.

Deepfake and manipulation of social media

We've all seen a video or picture that was too good (or too unbelievable) to be true. But deepfake technology can be used not only for entertainment, but it can also easily become a weapon. Serious damage can be done by manipulating and misleading people, especially when political or economic interests drive the attackers.

To be honest, it's a trend that I'm afraid of, because the notion of reliability and of truth is becoming more and more relative.

Quantum Threat - The New Era of Encryption

One of the most interesting technological directions is the development of quantum computers. I know that many people are still learning about the concept, but the effects are already being felt. In principle, quantum technology could be able to crack current encryption algorithms, which poses a huge risk.

I think this is an area where investment shouldn't be spared. The development of quantum-safe encryption is now not only an option but a necessary one.

IoT devices: more connectivity, more risk

The explosion of smart devices is opening new opportunities, but unfortunately with it comes an increase in vulnerabilities. A hacked IoT device, such as a thermostat or security camera, can be a serious part of a larger attack.

Personal data: most valuable currency

The demand for personal data has never been higher. I believe that individuals and companies alike need to be proactive about their data security, otherwise they could suffer serious losses.

The evolution of attack methods: what should we be prepared for?

Cyber-warfare and state-level attacks

According to Check Point analysts, by 2025, a significant proportion of cyber-attacks will be geopolitically motivated, in the form of sophisticated attacks backed by state actors. These attacks will be targeted at systems such as the financial sector or transport.

Speed and effectiveness of attacks

Fortinet experts warn that the exploitation of zero-day vulnerabilities will take place in nearly real time. Attackers are adapting defense systems faster and faster, which puts a lot of pressure on security teams.

Social engineering at new heights

Social engineering remains one of the most common forms of attack. Gartner points out that attackers can use AI to launch personalized phishing campaigns to deceive even the most sophisticated users.

New technologies for protection

Zero Trust: the new principle

The Zero Trust approach, which checks all access requests and only grants minimal access, will be a key security strategy in 2025. Forrester Research predicts that Zero Trust will become the norm in every sector in the coming years.

Automation and AI at the forefront of protection

Fortinet and Trend Micro agree that AI plays a key role in identifying and managing threats in real time. Automated systems not only speed up attack detection, but also reduce the risk of human errors.

Cyber insurance: moving to the next level

Gartner predicts that the cyber insurance market will see explosive growth by 2025 and will be essential for most businesses. Such insurances not only cover financial risks, but also encourage the implementation of better safety practices.

What can businesses and individual users do?

Company level: proactive protection is the key

Check Point recommends that companies invest in holistic security strategies that cover the supply chain, cloud systems and endpoints as well. Education and ongoing training of staff is essential to recognize the latest attack techniques.

Individual level: awareness and device safety

It is important for individual users to ensure that IoT devices are properly configured, and strong passwords secure with strong passwords. Palo Alto Networks underlines that regular updating of tools, and the use of two-factor authentication are essential to protect personal data.

Closing thoughts

The year 2025 will be full of challenges and opportunities for cybersecurity. Applying the trends and technologies highlighted by industry players will be essential to fight against constantly evolving threats. In my view, the most important thing is not only to think in terms of technology, but also to strengthen the security culture - both at company and individual level. Proactive defense, integration of new technologies and continuous education will be crucial to maintain security.
