About Sergio

Services provided through FUTURE XPERT-IS SARLU registered with the Paris RCS, an integration company where I am the majority owner.

Working with Future XPERT-IS SARL is not just working with a consultant, but with an official integration partner of several market-leading manufacturers such as Fortinet, HPE, HPE Aruba Networking, HPE Juniper, Cisco, Splunk, and Palo Alto Networks.

Working with an integrator consultant allows you not only to use a consultant, but a visionary capable of placing manufacturer orders, obtaining good prices, and having manufacturer expertise directly in your offices.
