What are the most common cyber threats?

The most prevalent threats are phishing emails, ransomware, business email compromise (fraudulent emails impersonating directors to redirect payments), and supply chain attacks. Most successful attacks exploit human error — making staff training as important as technical controls.

What is Cyber Essentials?

Cyber Essentials is a UK government-backed certification demonstrating a baseline standard of security across five controls: firewalls, secure configuration, access control, malware protection, and patch management. Many government contracts and large clients now require it, and the NCSC estimates it reduces common cyber attack risk by up to 80%.

How do I know if my business has already been compromised?

Signs include unexpected system slowdowns, inaccessible or encrypted files, unusual account activity, and colleagues receiving suspicious emails from your domain. Many attacks remain undetected for weeks — which is why continuous security monitoring is essential.

How much does it cost?

Comprehensive managed cyber security typically costs £15–£50/user/month. This compares favourably with the average cost of a single incident — which for a 50-person business can easily exceed £50,000 including downtime and remediation.

What should I do if my business is attacked?

Isolate affected systems immediately. Contact your IT support or security provider. If customer data is compromised, notify the ICO within 72 hours under GDPR. Contact your cyber insurance provider. Document everything throughout.

What?

What is business cyber security?

Business cyber security encompasses the tools, processes, and services protecting your organisation's data, systems, and devices from unauthorised access, theft, and disruption. A comprehensive programme combines technical measures — firewalls, endpoint protection, email security, multi-factor authentication — with human measures including staff training and incident response planning. For most SMEs, working with a managed security service provider who delivers this as a managed service is the most effective and cost-efficient approach.
