Understand managed IT — then see how we run it.

A plain-English guide to how good managed IT works, and where to go next across the Missan 365 services. No jargon for its own sake — just clear explanations and the guides behind each part of the service.

What good managed IT looks like

The same three things, whatever the provider.

Before any tool or contract, good managed IT comes down to a few principles. Use them as a benchmark — for us, or for anyone you are evaluating.

Proactive by default

Good IT is watched continuously and fixed before users feel it. If the first you hear of a problem is a complaint, the model is wrong.

Secure from day one

Security, backup, patching and identity are part of the service — not an upsell after an incident. Protection is assumed, and tested.

Accountable and visible

One service level agreement, one monthly report, one quarterly review. Leadership can always see what is being done and what comes next.

The jargon, in plain English

Four terms worth knowing before you choose a provider.

Managed IT comes with its own vocabulary. Here is what the core terms actually mean — no sales spin, just clear definitions.

What is an MSP?

A managed services provider (MSP) runs your IT as an ongoing service for a predictable monthly fee, rather than charging per fix when something breaks. The MSP takes responsibility for monitoring, securing, patching, backing up and supporting your systems to agreed service levels — so technology is managed continuously instead of repaired reactively.

What is RMM?

Remote monitoring and management (RMM) is the software an MSP uses to keep watch over your devices and servers from a distance. A small agent on each machine reports on health, applies updates and patches automatically, and allows secure remote support — which means many issues are detected and resolved before anyone on your team notices them.

What is an SLA?

A service level agreement (SLA) is the written commitment that defines how quickly issues will be responded to, usually by priority. Critical problems carry the fastest target, lower-priority requests a longer one. An SLA turns support from a vague promise into a measurable standard, so you know what to expect and the provider can be held to it.

What is managed backup?

Managed backup means your data is copied, stored securely and — crucially — regularly tested by your provider, rather than left to run unchecked. A backup is only useful if it can actually be restored, so a managed service verifies recovery, protects copies against ransomware, and includes cloud data such as Microsoft 365, not just the files on your servers.
