Assess
We inventory what is running, what it costs and where it is exposed. You keep the report.
Services
Day to day IT handled under a monthly agreement, so problems get resolved instead of queued.

Devices enrolled, patched and monitored. Tickets go to engineers who already have your documentation open. The monthly figure does not move when a month is busy.
Process
We inventory what is running, what it costs and where it is exposed. You keep the report.
Findings become a ranked plan with a price against each item. You approve before anything changes.
Work runs in named windows with a rollback, documented as it goes.
Questions
If yours is not here, ask it on a discovery call. There is no charge for the conversation.
More often we work alongside one. A common split is that the internal person owns the applications and the floor, and we own infrastructure, security and escalation.
Response targets are written into the agreement and vary by severity and by the plan you choose. They are stated in the quote before you sign, not left to interpretation afterwards.
