Based in Dordrecht, 1do handles IT and telephony for organizations moving away from on-premises setups toward Microsoft 365 and Microsoft Azure environments. Internet connections and in-office networking form a core part of the work, alongside integrations that link phone systems to platforms such as ERP software and Microsoft Teams.
Support runs through 1do's Supportcenter, which combines help desk assistance with proactive monitoring rather than fixing issues after they surface. The agency holds ISO 27001:2022 certification, reflecting the information security practices applied across its managed IT and telephony services.
