Andreas Fjellner

Senior Consultant – Incident Response (CSIRT)

Andreas has a background in the Swedish government and higher education sector, working with a broad range of Microsoft technologies.

Andreas got hooked on PowerShell back in 2011 and have used it with passion ever since. His favorite challenges are always solvable with PowerShell and they can probably be automated as well.

Aside from building stuff with PowerShell, Andreas is the happiest during a floorball workout or while riding the slopes.

About Truesec

Truesec was founded in 2005 by Marcus Murray. The idea was to gather Sweden’s top experts in IT security and build the business around the specialists’ drive.

Initially, Truesec undertook assignments such as penetration testing, incident management, and securing IT environments. Additionally, Truesec conducted lectures and training on system infiltration techniques and defenses against data breaches. By assembling a large number of specialists in cybersecurity, we could do more and drive developments within cybersecurity. We developed several tools and methods that gained international recognition.

Our mission: prevent breach and minimize impact.
