How much does a penetration test cost in the UK?
If you have been quoted £8,000 for a penetration test and wondered whether that is normal — it is. But it is not the only option anymore, and for most small and medium-sized businesses, it is not the right one either.
The honest price range for UK penetration testing
Traditional penetration testing in the UK costs between £5,000 and £20,000 for a web application engagement. Enterprise-level red team assessments can reach £75,000 or more.
Why automated penetration testing changes the calculation
Yrzo AI runs 75+ automated security checks against your website and delivers a full report in under 20 minutes. The findings are validated before they reach you — no false positives. The cost starts at £149 per scan.
What £149 gets you versus what £8,000 gets you
At £149, a Yrzo AI scan covers SQL injection, XSS, IDOR, JWT attacks, SSRF, CORS misconfigurations, admin panel exposure, subdomain enumeration, SSL certificate issues, cookie security, email spoofing protection, and 33 more checks.
At £8,000, a traditional firm gives you all of that plus manual testing of complex business logic and a CREST-accredited report for regulatory requirements.
The cost of not doing it
The ICO fined companies £7.5 million in 2024 alone for data breaches from preventable vulnerabilities. A breach costs businesses an average of £3.4 million.
