Frequently asked questions

In Leeds, UK, GDPR and the Data Protection Act 2018 require regular security testing. PCI-DSS mandates pentests for businesses that handle any kind of payment card details. Cyber Essentials Plus requires penetration testing for government suppliers. Additionally, ISO 27001 and the Cyber Security and Resilience Bill also strongly imply it.

The average cost ranges from £3,000 to £10,000 for small to medium-sized businesses. In larger organizations or complex IT infrastructures, rates can climb up to £20,000. For reference, a fair day rate is around £1,200, with the total cost determined by the number of days required to complete the penetration test.

Prioritize CREST accreditation as a baseline, followed by PCI ASV certification, which is required for PCI-DSS compliance. Then, consider the engagement model (manual, automated, or hybrid), reporting quality, compliance alignment, and cost. Check if the provider understands your specific compliance framework and, most importantly, ensure they take the time to learn your business workflows before scoping the engagement.

Web application and external network tests take 3–5 days; internal network tests take 5–8 days; and full security assessments take 10–20 days. The expected timeline from scoping to final report delivery is two to four weeks.

Testing for external network, web application, and cloud assessments is generally done fully remote. On-site presence is required only for internal network access, wireless testing, or physical security assessments. But it is recommended to choose providers based on accreditation and quality, rather than location.
