Frequently Asked Questions
Common questions about this service, methodologies, and deliverables.
All of the UK. We deliver on-site penetration testing from four bases: our Leeds headquarters (covering Yorkshire, the North, Midlands, and North West), our Newcastle Security Operations Centre (North East), our London office (London and the South East), and our Edinburgh office (Scotland). Remote testing phases, external infrastructure, web application, API, and cloud testing, reach any UK location with no travel involved.
Across our core coverage areas, Yorkshire, the North of England, the central belt of Scotland, and Greater London, on-site days carry no travel premium. For more distant locations we agree planned on-site days at scoping with any costs fixed up front, and deliver everything that can be done remotely from our UK offices. There are never surprise expenses on invoices.
Yes. Every engagement, wherever it is delivered, uses the same CREST-accredited methodology, the same employed UK-based testing team, and the same QA process. A penetration test in Cornwall or Glasgow is scoped, executed, and reported identically to one in London, at the same day rate.
