About UK Pen Testing
Accredited security testing, built around UK organisations
We help UK businesses and public bodies find and fix the weaknesses attackers look for, with penetration testing and attack surface management that runs all year, not once a year.
Who we are
A LevelUp Networks service
UK Pen Testing is the offensive security service of LevelUp Networks Ltd, a London-based technology services company. We bring enterprise-grade security testing to organisations of every size, with a single point of contact who understands your environment and your goals.
