From a record number of zero-day attacks to the proliferation of state-based attacks, 2024 has seen cyber threats escalate like never before.
With the release of the National Cyber Security Centre’s 2024 report, we look ahead to the trends predicted for 2025 and how organisations must adapt to a complex environment shaped by advanced technologies, sophisticated threat actors, and increased regulatory scrutiny:
Artificial Intelligence (AI) is transforming cyber security—for both defenders and attackers.
In 2025, cybercriminals are expected to deploy AI-enabled tools to automate reconnaissance, craft highly convincing phishing campaigns, and exploit vulnerabilities faster than ever. These AI-powered attacks will bypass traditional defences, making it critical for businesses to adopt advanced threat detection systems.
To mitigate this threat, organisations should prioritise AI-enhanced security tools capable of detecting anomalies in real time. But don’t underestimate the human element: rolling out employee training on recognising AI-driven social engineering attempts will play a vital role in reducing exposure to such attacks.
Ransomware remains one of the most pervasive and damaging cyber threats. By 2025, ransomware attacks are predicted to become even more sophisticated, targeting critical infrastructure, supply chains, and cloud environments.
Cybercriminals are also likely to adopt double extortion tactics, where they not only encrypt data but also threaten to leak it publicly if ransoms are not paid.
To defend against ransomware, businesses must implement robust backup strategies, network segmentation, and endpoint protection. Regular vulnerability assessments and penetration testing are also advised to help identify and address potential entry points before attackers exploit them.
As businesses increasingly rely on third-party vendors and partners, supply chain vulnerabilities are emerging as a significant concern.
In 2025, attackers are expected to target supply chains to exploit weak links and gain access to larger organisations. These attacks can cause widespread disruption and damage the reputation of businesses that fail to secure their supply chain ecosystems.
To combat this, organisations should enforce stringent third-party risk management practices. This includes conducting regular supplier audits, ensuring compliance with cyber security standards, and adopting frameworks like Cyber Essentials to strengthen baseline security measures.
Insider threats – whether malicious or unintentional – will continue to pose a significant challenge in 2025.
With hybrid working models becoming the norm, the risk of employees misusing access or equipment (known as shadow IT), falling victim to social engineering, or accidentally exposing sensitive data increases.
National Insurance rises also make redundancies more likely. This potentially means a large number of disgruntled employees looking for leverage against employers or to utilise business data for gain.
Businesses must adopt a zero-trust security model, which enforces strict access controls and continuous monitoring of user activities. Implementing behavioural analytics tools can help detect unusual activity patterns, while comprehensive employee awareness programmes can reduce the risk of accidental breaches.
Don’t underestimate the power of workplace IT policies as well, which can give a route for redressal should shadow IT lead to the risk of data compromise.
As organisations integrate Internet of Things (IoT) devices and critical infrastructure systems, attackers are shifting their focus to exploit these often-overlooked vulnerabilities. This has already had some spectacular results.
In 2025, IoT-enabled attacks are likely to rise, targeting sectors like healthcare, manufacturing, and energy. These attacks can disrupt essential services and have far-reaching consequences.
To address this threat, businesses should prioritise securing IoT devices through regular firmware updates, secure configurations, and network segmentation.
Taking up a ‘defence-in-depth’ approach – layering multiple security measures – can also help reduce the risks associated with critical infrastructure attacks.
Preparing for these evolving threats requires a proactive approach to cyber security. Here are key steps businesses can take to develop threat protection and enhance their resilience:
Cyber security is no longer optional—it’s a critical component of modern business resilience.
The cyber security threats of 2025 demand vigilance, adaptability, and a commitment to proactive security measures. By understanding and preparing for these threats businesses can protect their operations, safeguard sensitive data, and maintain trust with stakeholders.
ToraGuard offers insight into crafting a cyber security strategy for 2025, with a focus on the current challenges, evolving regulations, risk management strategies, and budget optimisation.
Cyber attacks are an inevitable part of modern operations: no organisation is immune. Having a structured approach to handling security incidents is critical to minimising damage, protecting sensitive data, and ensuring business continuity.
With growing cyber threats, regulatory pressures, and unprotected legacy systems, it’s clear that traditional protection methods are no longer enough.
