What sets us apart

Experiences makes the difference.

Many years of operational experience and technical expertise enable us to act carefully and decisively even in complex situations. In personal protection in particular, a thorough assessment of potential risks is crucial — as is the ability to act unobtrusively and effectively at the same time.

Customers from business, industry, politics, sports and the public sector have relied on our expertise for years. We take responsibility for them — and secure what is important to them.

Ein Blick auf unsere Chronik

Looking back:
10 years of Cesiun

Ten years of Cesiun mean ten years of responsibility, development and trust. Since 2016, we have been supporting companies, institutions and private individuals with individual security solutions — both nationally and internationally. Our milestones represent continuous growth and clear principles.

2016

Founding of Cesiun GmbH

Cesiun GmbH was founded in 2016 — with the aim of offering security services at the highest level. The following years were followed by the establishment of new departments, international assignments and the continuous development of our professional and organizational structures.

2017

Development of the Personal Protection Department

This year, the personal protection department will be specifically set up and implemented into the crisis management response team of an international corporation — the start of our long-standing cooperation with industry.

2017

DIN ISO9001 certification

In 2017, Cesiun GmbH was certified according to DIN ISO 9001 for the first time. Since then, we have relied on demonstrably structured quality management — as the basis for transparent processes, comprehensible processes and continuous improvement in all areas of service.
