QTE-1 · EXTERNAL SCOPE
External penetration testing quotes
An external penetration testing quote needs three inputs: your live internet-facing host count (not your allocated ranges), where those hosts sit (cloud, colocation or on premises), and the compliance driver behind the test.
We scope external infrastructure at roughly 50 live hosts per tester-day. Most external engagements run 3 to 5 days, from £3,500 and typically £6,500 to £12,000, agreed as a fixed price for the defined scope rather than a multiple of a day rate. See how we test on our external infrastructure penetration testing page, or send the form and your figure comes back within 24 hours.
A web application penetration testing quote is scoped on user roles, whether testing is authenticated, and how many dynamic pages and API endpoints sit behind the login.
A single-role application with standard workflows sits at the £5,000 end; a multi-tenant platform with several roles, an admin console and a public API runs 6 to 12 days and typically £8,000 to £18,000, fixed before we start. The same form also covers API, cloud, mobile application, internal infrastructure, phishing and PCI segmentation scopes.
Fixed price, agreed before we start. Most tests begin at £3,500; a standard web application test is £8,000–£18,000. See full pricing.
