S3 Company offers a full range of data center services.

We have been providing physical and virtual servers to clients from all over the world, located in various data centers across Europe since 2010. In 2018, we took the next step along our path and we built our first own data center in Sofia (Bulgaria). It currently houses two colocation facilities with more than 5000 U in use.

Our continuous commitment to invest in research and development enables us to consistently implement innovations and improve the security and stability of our services.
