Posts about Cyber Security

Network security protects an organisation’s IT infrastructure, systems, and data by preventing unauthorised access, detecting threats, and ensuring secure communication across networks. In the UK, businesses increasingly rely on integrated solutions combining firewalls, access controls, monitoring, and zero trust models to maintain security across cloud, on-site, and remote environments.

Crisis readiness reality check

Cyber insurance premiums for UK businesses have risen sharply in recent years. Insurers are tightening underwriting requirements, increasing excesses, and in some cases refusing cover altogether - particularly for organisations with weak cyber security controls.

For years, organisations have measured their cyber maturity by how well they prevent incidents. How many controls are in place. How many standards are met. How clean the audit looks.

Organisations often use the terms MDR, SIEM, and SOC interchangeably, but they are not the same thing. While all three relate to cyber security monitoring and response, they serve different purposes and levels of operational maturity. Understanding the differences is essential for UK organisations looking to improve threat detection and response.

Artificial intelligence is accelerating innovation, but it is also reshaping the cyber threat landscape faster than most organisations expect. From highly convincing phishing campaigns to deepfake impersonation and hidden AI-driven manipulation, the assumptions that once underpinned cyber security are no longer reliable.

This Q&A answers the most common and critical questions raised during our Secure AI in Action webinar. It explores how AI is reshaping the cyber risk landscape, where organisations are most exposed, and what practical steps leaders can take to defend the business while enabling responsible AI adoption. If you are looking for a broader view of how AI is driving these changes and what organisations must do next, we explore this in more detail in our companion article, Secure AI in action: how AI is reshaping cyber risk and what organisations must do next.

Remote and hybrid working are now standard across many industries. While this shift has delivered flexibility and productivity gains, it has also expanded the attack surface for cyber criminals. Home networks, personal devices, cloud platforms, and collaboration tools all introduce new risks.
