Profile:

  • I started my career as an IT Administrator in a startup company and quickly discovered my passion for Cybersecurity. It all started with the mighty ISA/Forefront TMG Server from Microsoft. After some time in Network Security, I discovered Active Directory as my new security playground and feel in love with the technology. At this time, I never thought I would once work for Microsoft. Fast forward a couple of years I started as a Cybersecurity Engineer at Microsoft helping customer in their most pressures moments recovering their Active Directory from a Compromise. I'm thankful for the experience I gained at Microsoft at that time. Helping dozens of companies dealing with Cyberattacks in different roles was an incredible learning
  • As Microsoft started its own set of security products, I was blessed to be one of the first do get my hands on Windows ATP(MDE), ATA(MDI) and Sentinel from day one. I discovered Cloud Security as my new passion. Recently Secure Service Edge was introduced closing the last gap in the zero-trust strategy and working with the first early adopters of that technology was again a great learning. After 8 Years at Microsoft and a total of 20 years of experience, I received a call that was impossible to decline, and I joined shiftavenue as their CISO continuing my security journey and enabling companies navigating the Cybersecurity landscape. Now I created Sovereign Cyber to continue to make the IT World a safer place. Möchtest du, dass ich diesen Text noch auf andere Weise für dich strukturiere?
