Growing businesses outgrow their IT quietly. The setup that worked at 20 people strains at 60 and breaks at 120. This checklist is a practical way to audit your foundation. Go through each section — anything you cannot tick with confidence is a gap worth closing before it becomes an incident.
Hardware and assets
- You have a complete, current inventory of all hardware (IT asset management).
- No critical systems run on end-of-life or unsupported hardware.
- Warranties and support contracts on critical equipment are current.
- Capacity has been reviewed against current and projected growth.
Network and connectivity
- Network hardware is modern and supported.
- Internet bandwidth matches actual usage with headroom.
- Critical connectivity has redundancy (no single internet link as a single point of failure).
- Guest and IoT traffic is separated from your core network.
Security
- A firewall is in place and its rules are reviewed.
- Multi-factor authentication is enforced on key accounts.
- Endpoint protection is deployed on all devices.
- Systems are patched on a defined schedule — see endpoint security best practices.

Backup and recovery
- Critical data is backed up automatically.
- Backups have been tested by actually restoring from them.
- A documented disaster recovery plan exists.
- Recovery time and recovery point objectives are defined.
Documentation and management
- Your network and systems are documented (not just in one person’s head).
- Monitoring is in place across critical systems.
- There is a clear process for logging and resolving issues.
- Someone is accountable for IT — internally or via a provider.
