About us


Since in 1991 the company S3I was created thanks to the effort and knowledge brought by several engineers who had previously worked for Digital Equipment Corporation until the present moment, our company has always sought to offer an added value to its customers. For this reason, S3I has created a portfolio of services to cover all the areas related to information technology, electricity and communications.

The mission of S3I is to make the decision easy to our clients when trying to invest in technology, ensuring that they are advised of the latest technologies in the market by our team specially taught on those.
