The AMVIA Recommendation
The AMVIA Recommendation
Start with Cyber Essentials. It takes two to eight weeks, costs £300–£1,500 managed, and demonstrates security credibility to insurers and procurement teams. Once certified, use it as a foundation for ISO 27001 if your client base or data sensitivity demands it. AMVIA manages both pathways and can advise which fits your current risk profile.

BEC is a type of fraud where attackers impersonate executives or suppliers to trick employees into transferring funds or sharing sensitive data. BEC attacks increased 33% in 2025. The average loss per BEC incident is $137,000. Even organisations with fewer than 1,000 employees face a 70% weekly probability of a BEC attempt.
The average cost of the most disruptive breach is £3,550 for UK businesses. For businesses that experienced negative outcomes such as data loss or financial theft, the average cost rises to £8,260. Medium and large businesses face average costs of £10,830 per disruptive incident.
MFA requires two or more verification methods to access an account. Microsoft reports that over 99.9% of compromised accounts did not have MFA enabled. Only 40% of UK businesses have two-factor authentication enabled (DSIT 2025). MFA can prevent more than 99.9% of account compromise attempts.
UK businesses typically allocate 13.2% of their total IT budget to cybersecurity. More than half of UK small businesses increased their cybersecurity spending in 2024. 85% of UK firms plan to boost their cyber budget for 2026. The cost of prevention is significantly less than the average breach cost of £3,550.
