Corporate guidelines

The basis of our corporate activity

CES is one of the leading manufacturers of locking systems and electronic access control systems. Continuing our long tradition into the future, we want to provide generations to come with high-quality and innovative security systems which offer a reliable and convenient protection to both people and their valuables.

Being an independent, family-owned enterprise, we are committed to maintaining reliable and sustainable relations with our business partners. However, to achieve this goal, lasting financial independence is required. To maintain this independence as a supplier of innovative developments in the long run, we endeavour to achieve a return on sales of 10% with continuous growth.

CES acknowledges its responsibility to the owner family, the employees at all locations, the social environment and the region of Velbert/Niederberg in Germany. Compliance with legal obligations and official requirements is a matter of course in our daily dealings.
