There's a predictable moment in every growing company when the IT setup that worked perfectly suddenly starts causing daily friction — Wi-Fi that buckles in the afternoon, a shared drive nobody can find anything in, onboarding that takes a week because every tool is set up by hand.
The infrastructure that got you to 20 people simply doesn't scale to 80. This checklist covers the foundations to put in place before growth forces the issue — so scaling is a non-event instead of a fire drill.
1. Network and connectivity
- Business-grade redundant internet (primary + failover) with automatic cutover.
- Segmented network: separate VLANs for staff, guests, servers, and IoT/devices.
- Wi-Fi sized for density, not just coverage — meeting rooms and open floors need far more capacity than a floor plan suggests.
- Centralised, cloud-managed networking so you can see and fix issues remotely.
2. Identity and access
- Single sign-on (SSO) across your core apps — the single highest-leverage move for both security and onboarding speed.
- Multi-factor authentication enforced everywhere, no exceptions.
- Role-based access groups so joiners and leavers are one action, not twenty.
- A documented joiner/mover/leaver process.
3. Devices and endpoints
- Standardised hardware builds and a managed device platform (MDM).
- Disk encryption and endpoint protection on every device.
- Automated patching with reporting.
4. Data and resilience
- The 3-2-1 backup rule: three copies, two media, one off-site — tested.
- Defined recovery time and recovery point objectives (RTO/RPO) per system.
- A written, rehearsed disaster-recovery runbook.
5. Visibility and governance
- Asset register covering hardware, software licences, and refresh dates.
- Centralised logging and monitoring with alerting.
- A lightweight IT policy staff actually read.
How to use this
Score each item red / amber / green. Anything red below 30 staff is urgent; anything amber should have an owner and a date. The goal isn't to do everything at once — it's to fix foundations in the right order so each stage of growth lands on solid ground.
