2025 Trends

The more (complex) technology we use, the bigger the attack surface for cybercriminals. Here’s a brief overview of the trends shaping cybersecurity this year and what you can do to strengthen your organization’s resilience.

AI

Artificial Intelligence (AI) is playing an increasingly important role in cybersecurity. On one hand, AI helps detect and combat cyber threats in real time by analyzing vast amounts of data. On the other, cybercriminals are leveraging the same technology to carry out ever more sophisticated attacks. Setting up attacks has become easier, even for those with little technical knowledge. AI-generated phishing emails, for example, are now almost indistinguishable from real ones, making incidents more likely.

Zero-Day Vulnerabilities

Zero-day vulnerabilities remain a major risk. These are unknown weaknesses in software or hardware that hackers exploit before patches are available. As IT environments become more complex and new technologies are adopted rapidly, these vulnerabilities are being discovered and exploited faster than ever. Continuous monitoring and advanced detection systems are essential to stay ahead of zero-day attacks.

Cybersecurity Mesh Architecture (CSMA)

Traditional security models fall short when organizations use hybrid and cloud-based infrastructures. Cybersecurity Mesh Architecture (CSMA) offers a solution by allowing security tools to interoperate flexibly, regardless of where data and applications are located. This creates a more dynamic and efficient security strategy that aligns better with modern digital networks.

Supply Chains

Supply chain attacks are on the rise. Cybercriminals no longer just target large organizations but also attempt to infiltrate them via weaker links in the chain, such as software vendors, cloud service providers, or other third parties. It is therefore crucial to thoroughly assess suppliers, enforce strict security requirements, and maintain continuous oversight over the entire chain.

The Human Factor

No matter how advanced and “smart” technology becomes, human error remains one of the leading causes of security breaches. Phishing attacks, weak passwords (yes, still!), and unintentional data leaks are common. Investing in regular security awareness training and strong identity and access management measures is still the best way to minimize these risks.

AI (Again)

Beyond the risks AI introduces, it is also a powerful weapon in defense. AI-driven security solutions can analyze threats in real time, automatically respond to incidents, and even predict where new vulnerabilities may arise. This allows organizations to take a proactive approach to cybersecurity rather than simply reacting after the fact.

Cloud Security and Misconfigurations

The shift to cloud services comes with new challenges. Misconfigured cloud settings are one of the leading causes of data breaches. Think of unsecured S3 buckets or improperly set access controls. Organizations must regularly conduct audits, implement automated compliance checks, and strictly regulate access management to mitigate these risks.

Insider Threats

Internal threats—whether intentional or accidental—are a constant risk. With more employees working remotely and having broader access to sensitive data, the likelihood of insider threats has increased. Zero Trust architectures, regular awareness training, and advanced detection and monitoring tools help mitigate these risks.

Convenient Software

Employees are increasingly using online tools and software, such as productivity apps, file-sharing services, and browser extensions. We call this Shadow IT. While these tools can improve efficiency, they also introduce risks. Poorly secured software can leak sensitive business data, contain malware, or grant unauthorized access to corporate networks. “This software requests access to your network” – sound familiar? It is crucial for organizations to implement clear policies on software usage, including whitelisting approved applications and continuously monitoring network activity. Security awareness training also helps employees make better-informed decisions when installing and using software.

Balancing Security and Usability

Security is essential, but it shouldn’t come at the cost of productivity. Overly complex security protocols often lead to frustration, causing users to engage in risky behavior such as writing down passwords, bypassing security measures, or installing “helpful” external software (sound familiar?). Taking user behavior, location, and device status into account can help maintain both security and usability.

In Summary

By increasing security awareness and strengthening supply chains and cloud environments, organizations can better protect themselves against threats. The question isn’t if you’ll be targeted by a cyberattack, but when. Taking the right steps now is crucial to minimizing the potential impact—and cost—of a breach.
