Multilingual website and new visual identity
Today, Monday 5th of June, also marks the reinforcement of the accessibility of the CCSS's services with the publication of its website in English and German. This enhancement is an important step in the CCSS's digitalisation strategy.
This important date in the history of the CCSS is as well the occasion for a change in the institution's visual identity, with the unveiling of its new logo. The new logo will be used on all CCSS communication media, including letters, the website, electronic documents, social networks and posters.

The new design is intended to make the CCSS more easily identifiable by reflecting the strong values of its purpose: stability by retaining the previous colors, professionalism, seriousness, transparency and accessibility.
The aim of all these changes is to bring the CCSS closer to its users by making its services more accessible and transparent.
