Penetration testing FAQs — London
Q.What is penetration testing?
Penetration testing (pen testing) is a simulated cyber attack on your systems, networks, or applications — performed by ethical hackers with your authorisation. The goal is to identify security vulnerabilities before real attackers do. A pen test produces a detailed report of findings and remediation recommendations.
Q.How much does penetration testing cost in London?
Penetration testing costs in London vary based on scope. A network pen test for a typical SME starts from approximately £1,500–£3,000. Web application pen tests start from £2,000–£5,000 depending on complexity. Coreitech provides fixed-price quotes after a scoping call.
Q.How long does a penetration test take?
A typical network pen test takes 2–5 days. Web application pen tests typically take 3–7 days. A full report with findings and remediation recommendations is delivered within 5 business days of the testing period completing.
Q.Do I need penetration testing for Cyber Essentials?
Cyber Essentials itself does not require a pen test, but Cyber Essentials Plus does include a vulnerability assessment. For ISO 27001, PCI DSS, and many enterprise client requirements, regular penetration testing is mandatory.
Q.Is penetration testing legal?
Yes — penetration testing is legal when performed with the explicit written authorisation of the system owner. Coreitech only conducts pen tests with a signed scope of work and authorisation letter, following NCSC guidelines for responsible testing.
