About pentests.dk

pentests.dk is Christian Lysel’s sole proprietorship, delivering professional penetration tests and IT security services. The company was originally established in 1997 under the name SpindelNet for operations and troubleshooting of IT infrastructure, including firewall/VPN, networking, and servers for a number of clients — including Slangerup Municipality, Græsted-Gilleleje Municipality, Avis Car Rental A/S, and Plus Pack A/S.

In 2024, SpindelNet changed its name to pentests.dk to focus on penetration testing.

Today, pentests.dk focuses on helping companies map and remediate security risks in web applications, networks, and IT systems through professional, tailored penetration tests.
