The shock is deep for everyone. Unfortunately, Klaus had to leave us much too early. Our deepest sympathy and sincere condolences to his wife, family and all friends and acquaintances.

“With the loss of Klaus, we do not only lose a managing director, but also an irreplaceable friend, promoter and mentor. We and the entire team will give our everything to carry on his work and legacy with highest motivation in order to let his successes be followed by many more.

The life of our owner, managing director, mentor and friend Klaus Rehborn was marked by countless success stories. His business career began with his employment at SIEMENS AG. During this time, Klaus Rehborn revolutionized the alarm system technology, camera surveillance and video journaling in the banking sector in various projects. He shared his know-how with books such as “Praxis der Alarmanlagen”, published by the Karamanolis publishing house, “LADE- UND NETZGERÄTE”, published by the ELEKTRA publishing house, as well as with countless specialist articles that he wrote until the end. With the founding of ISR-NETCOM GmbH, the founding of SECUDOS GmbH, the founding of Landitec Distribution GmbH and the founding of SECUDOS FAR EAST PTE. LTD., Klaus Rehborn drew his successful business career.

We gladly remember the countless company outings, company celebrations, private gatherings, but also the normal everyday life in the office and the always friendly and personal relationship. Klaus always had an open ear and supported the team even in their private lives. Klaus was an enthusiastic amateur radio operator and passionate motorcyclist, as well as an incessantly curious promoter of new technologies. In addition to the successful business career, Klaus was happily married to Petra Rehborn for 42 years, who supported him in the areas of human resources and financial management (CFO) from the beginning of his independence.

THANK YOU, Klaus. May you rest in peace.

Petra Rehborn, who held the position of CFO until the death of her husband, will continue to manage all business with the proven team in the spirit of Klaus Rehborn, together with Markus Gringel and Yasin Imren.

The businesses of SECUDOS GmbH are going to be managed by Markus Gringel, Yasin Imren and Petra Rehborn. (Petra Rehborn is appointed as Managing Director.)
