A healthy IT environment is not defined only by whether computers are switched on. Growing businesses need clear ownership, current records, tested recovery and repeatable support processes.
1. Confirm who owns every system
Start with a simple inventory of users, laptops, desktops, servers, network devices, cloud subscriptions, business applications, domains, email platforms and backup services. Record the internal owner, technical administrator, vendor and renewal date for each important item.
2. Review identity and access
- Remove accounts belonging to former employees or unused vendors.
- Enable multi-factor authentication where supported.
- Review administrator accounts and shared passwords.
- Document the process for onboarding, role changes and offboarding.
3. Check endpoint and patch health
Confirm that every supported device has current operating-system updates, active endpoint protection, disk encryption where appropriate and a known support status. Unmanaged devices should be identified before they become a security or compliance gap.
4. Validate servers and network services
Review server storage, event logs, failed services, certificate expiry, DNS, DHCP, firewall rules, VPN access, Wi-Fi coverage and ISP escalation details. A current network diagram and IP record can reduce troubleshooting time during an incident.
5. Test backup and recovery
A successful backup notification is not the same as a successful recovery. Select representative files, mailboxes, databases or virtual machines and perform controlled restore tests. Record the recovery time, gaps and responsible owner.
6. Review cloud, email and licensing
Check unused cloud resources, subscription ownership, mailbox security, SPF/DKIM/DMARC records, storage growth, licence assignment and upcoming renewals. Remove waste without weakening operational coverage.
7. Turn findings into a priority plan
Separate urgent risk items from reliability improvements and future projects. A useful plan should show the issue, business impact, owner, estimated effort, dependency and next review date.
Recommended review cycle
Run a lightweight review every quarter and a deeper assessment before major hiring, office changes, cloud migration, application rollout or contract renewal.
