Cyber security: common questions.
What is Cyber Essentials?
Cyber Essentials is a UK government-backed certification scheme that shows your business has basic technical controls in place to protect against common cyber attacks. It's increasingly required for public sector and supply chain contracts, and is a recognised trust signal for customers and insurers.
Why is cyber security important for my business?
43% of UK businesses reported a cyber security breach or attack in the last 12 months (Cyber Security Breaches Survey 2025, GOV.UK). A single incident can mean downtime, financial loss, regulatory exposure, and reputational damage. Proactive protection is significantly cheaper than recovery.
How much does Cyber Essentials certification cost?
Costs vary depending on business size and complexity. Holker IT includes guidance and gap-assessment support as part of our managed cyber security service. Get in touch for a quote specific to your organisation.
What is cyber security insurance and do I need it?
Cyber insurance covers financial losses from data breaches, ransomware, and other cyber incidents. Most insurers now require evidence of baseline controls, such as MFA and endpoint protection, before offering cover. Our four-pillar framework maps directly to typical insurer requirements.
What are managed cyber security services?
Managed cyber security services mean an external provider like Holker IT continuously monitors, maintains, and improves your security controls (covering identity, endpoints, network, and email) rather than your team managing tools in-house.
