25 years ISL

Let's take a trip back in time, to the year 1999! Do you remember the Y2K problem? That's right, the year before the turn of the millennium caused a lot of excitement in the IT world. But in the midst of all the excitement, something significant happened: ISL Internet Sicherheitslösungen GmbH was founded on May 14, 1999! 

From developing one of the world's first Network Access Control systems to pioneering solutions such as a Security Operations Platform and Identity & Access Management, ISL has been the key player in successful IT security for 25 years.

We are the past, present and future of IT security.
