How accurate are the estimates?

They use typical UK figures for staff costs, employer overheads, disruption and energy prices, so they show the scale of a cost rather than an exact amount. For figures based on your own systems, book a free IT & security review.

Why calculate the cost of downtime rather than repair fees?

Repair fees are usually a small part of what an outage costs. The bigger losses come from staff who cannot work, delayed orders, missed deadlines and unhappy clients. Knowing your hourly cost shows whether backups, failover connections or better support pay for themselves.

How can Denwen help reduce these costs?

Proactive monitoring and patching catch many problems before they cause downtime, tested backups shorten recovery, and written response targets mean you know how quickly an engineer will be on the problem.

Can the security check help with Cyber Essentials or cyber insurance?

The security check covers the same basics that Cyber Essentials and most cyber insurance questionnaires ask about, such as multi-factor authentication, patching and backups. It is not a formal assessment, but we can review your answers with you and help you prepare for one.
