THE REALITY
Where IT quietly creates operational friction
For most Sussex businesses, IT problems rarely start with one major outage. They build quietly through reactive support, inconsistent Microsoft 365 management, unmanaged devices, backup uncertainty, cyber security gaps and poor day-to-day visibility.
Reactive support & recurring issues
Weak onboarding / offboarding
Unmanaged devices
Cyber security gaps
Connectivity instability
Supplier fragmentation
Backup uncertainty
Poor visibility & monitoring
