Community viewpoint: Cyber trends in 2025
What's occuring, and how to adapt your defences to an evolving landscape
What's occuring, and how to adapt your defences to an evolving landscape
2025 brings with it both new opportunities and challenges in protecting sensitive information and maintaining the integrity of digital systems. Here are some of the key cybersecurity trends our members are talking about that are shaping the industry this year.
Artificial intelligence (AI) and machine learning (ML) are playing pivotal roles in cybersecurity. Organisations are leveraging AI to detect and respond to threats in real time, significantly reducing reaction times to breaches. Advanced threat detection systems use ML algorithms to identify anomalies in network behaviour, helping to prevent zero-day attacks.
The downside of AI? The bad guys use it too! Cybercriminals are also using AI to craft more sophisticated phishing attacks, bypass traditional defenses, and automate malicious activities. This arms race underscores the importance of staying ahead with robust AI-driven security systems.
The shift toward a Zero Trust security model continues to gain momentum. This approach assumes that no user, device, or system can be trusted by default, regardless of whether it resides inside or outside the organisation’s perimeter.
With the rise of remote and hybrid work environments, implementing Zero Trust has become essential. Multifactor authentication (MFA), continuous monitoring, and micro-segmentation are key elements being widely adopted to minimise risks and secure sensitive data.
As quantum computing technology advances, traditional encryption methods face unprecedented challenges. Quantum computers have the potential to break widely used cryptographic algorithms, threatening the security of sensitive data across industries.
In response, organisations are investing in quantum-resistant cryptography and preparing for a post-quantum era. The government is also establishing frameworks to regulate the use of quantum technologies to prevent misuse by cybercriminals.
Ransomware remains a significant threat, but there are shifts in its delivery mechanisms. The rise of Ransomware-as-a-Service (RaaS) allows even non-technical cybercriminals to deploy ransomware attacks by subscribing to pre-built platforms.
These services lower the barrier to entry for cybercriminals and have contributed to a surge in ransomware incidents targeting small businesses, healthcare systems, and critical infrastructure. Organisations must adopt proactive strategies, such as robust backup systems and incident response plans, to mitigate the impact of ransomware.
The proliferation of IoT devices has introduced new vulnerabilities to networks. Attackers increasingly exploit IoT devices as entry points for larger network breaches. Cybersecurity for IoT has become a priority, with manufacturers implementing stronger device-level security and businesses deploying network segmentation to limit IoT-related risks. Improved regulatory standards are also pushing toward greater accountability for securing connected devices.
The demand for skilled cybersecurity professionals continues to outpace supply in the UK. Because of this, organisations are investing in training programmes, certifications, and partnerships with academic institutions to bridge the gap. Automation and AI-driven tools are also being utilised to compensate for workforce shortages, enabling existing teams to focus on high-priority tasks.
With increased reliance on data-driven technologies, the government is introducing stricter data protection regulations. Compliance with laws such as GDPR, CCPA, and other regional frameworks remains a challenge for organisations. Privacy-focused technologies, such as secure multi-party computation and homomorphic encryption, are becoming mainstream to ensure compliance and protect user data.
The cybersecurity landscape in 2025 will be shaped by technological advancements and evolving threats. Organisations must stay agile, adopting innovative solutions and fostering a culture of security awareness to navigate this dynamic environment. Proactive investment in cybersecurity is no longer optional but essential for maintaining trust and resilience across your business.
