The Threat Landscape in 2025 and How to Protect Your Data

2025 has brought its fair share of cyber incidents—how prepared are you?

This year is already proving to be a busy one for cybercriminals. While technology is moving at breakneck speed—bringing loads of benefits—it’s also opening new doors for attackers. We're seeing more cyberattacks than ever, and they're getting smarter by the day.

The big question for 2025: is your organisation ready to keep up?

To help you stay ahead, we’ve done the hard work and read Fortinet’s 2025 Threat Landscape Report—so you don’t have to. In this blog, we’re breaking down the key insights and trends, along with practical steps you can take to stay protected.

Whether you work in IT, InfoSec, or compliance, this guide will help you navigate the fast-changing threat landscape and put the right defences in place before trouble hits.

Navigating the new horizon of cyber threats

Five key challenges shape the threat landscape:

1. Ransomware is hitting bigger targets

Ransomware has grown up. It’s no longer just hitting small businesses—it’s going after critical infrastructure like power grids and transport networks. And thanks to AI and machine learning, these attacks are faster, stealthier, and harder to stop.

Example:

Recent automated ransomware attacks on the energy sector demonstrated the devastating potential of targeting critical services. Operations were down for weeks, costing millions.

How to protect yourself:

• Conduct regular backups of critical assets and store them in secure, air-gapped environments.
• Implement proactive threat exposure management to locate, monitor, and mitigate vulnerabilities.
• Deploy advanced endpoint detection and response (EDR) solutions to detect ransomware execution in real time.

2. Insider threats are on the rise

With hybrid work here to stay—and economic pressures mounting—more organisations are seeing risks from within. Whether it’s negligence or malicious intent, insiders are becoming a bigger part of the problem.

How to protect yourself:

• Employ user behaviour analytics to flag unusual activity by employees.
• Enforce strict access controls based on least privilege across sensitive systems (i.e., Zero Trust).
• Regularly review and update insider threat management strategies, ensuring they adapt to changing work environments.

3. Data privacy rules are getting complicated

Trying to stay compliant across multiple regions? You’re not alone. Global data laws are becoming more fragmented, with every country seemingly doing its own thing.

Example:

The mix of EU GDPR, Australia’s data laws, and emerging US regulations has many companies struggling to keep up.

How to protect yourself:

• Use a centralised platform to track compliance requirements by region.
• Automate compliance monitoring workflows to remain aligned with ongoing regulatory changes.
• Conduct regular audits to verify adherence and address gaps.

4. The cybersecurity talent gap isn’t closing

There just aren’t enough cybersecurity professionals to go around. Demand is skyrocketing, but supply? Not so much. This is leaving many businesses understaffed and exposed.

How to protect yourself:

• Leverage AI and automation to offset the resource shortage, particularly for repetitive tasks like patch management and threat detection.
• Invest in upskilling initiatives for existing employees, offering certifications and hands-on practice.
• Collaborate with external security service providers for specialised expertise.

5. The attack surface keeps growing

More IoT devices. More cloud apps. More complexity. All of this adds up to a bigger attack surface—and more opportunities for attackers to slip in unnoticed. With interconnected ecosystems, even a small vulnerability can open the floodgates to extensive damage.

Example:

Automated scanning tools like SIPVicious and Qualys have surged in popularity, facilitating reconnaissance that identifies vulnerable IoT environments. Attackers are targeting protocols like SIP and Modbus TCP to breach systems efficiently. 

How to protect yourself:

• Map and continuously monitor your evolving attack surface with automated tools.
• Tighten configurations for IoT devices and adopt best practices like secure firmware updates.
• Segment networks to restrict lateral movements and limit potential attack scopes.

Practical tips to outsmart your opponents

Defending against modern threats takes more than just firewalls and antivirus. It’s about being proactive, layered, and strategic. One approach gaining traction is Continuous Threat Exposure Management (CTEM)—a way to constantly test, prioritise, and close security gaps.

1. Simulate real-world attacks:

Pen tests and red teaming help you find weaknesses before attackers do.

2. Prioritise high-risk vulnerabilities:

Focus on the vulnerabilities most likely to be exploited.

3. Automate security testing:

Leverage AI and machine learning to perform rapid and accurate testing across environments.

4. Utilise dark web intelligence:

Monitor activity on the dark web to anticipate threat actor movements and prepare countermeasures.

By implementing these strategies, you equip your organisation with the means to not only survive but thrive in an increasingly complex cyber threat environment.

Stay informed and confident

The cybersecurity challenges of the future require action today. Organisations that take steps to understand and address these threats will gain a competitive advantage.

This means tackling issues like ransomware, insider threats, and compliance challenges while leveraging modern technology to stay agile.
