Managed IT services is a fully managed service: we take care of your IT on a daily basis (helpdesk, monitoring, maintenance) with contractual SLAs. On-site staffing is a skills placement: a technician works at your premises, under your direction, for a defined period.
Our plans start at EUR 25 excl. VAT / workstation / month for basic support, and go up to EUR 60-90 excl. VAT / workstation / month for full coverage (monitoring, cybersecurity, cloud). Monthly contracts, cancellable with 30-day notice.
