About us


CSS Computer Security Service GmbH was founded in 1984 with the aim of offering innovative solutions in the field of computer security. Since then, we have pursued this goal in almost all areas that span an ever-changing security architecture. Today, we offer the necessary hardware and software for the security industry, security engineers and all companies with sensitive control tasks.

Thanks to 39+ years of experience relating to guard control systems and an international network of long-standing suppliers and trading partners, we can provide you with expert advice and work with you to find the optimum solution for your security requirements – and all at a fair price-performance ratio, of course.

With a view to sustainable customer relationships, we not only offer you the product, but also the complete after-sales service: starting with competent German-speaking support, product training and repairs and maintenance work via remote maintenance or directly on site. That’s why our team is at your side. See for yourself our expertise in IT and security. Get to know our CSS team. You can find our most frequent target groups here.
