The challenge of Evergreen IT
Microsoft 365 is continuously improving, often making it challenging for organisations to keep up. Without proper management, the rapid pace of change can strain resources. As a leading enterprise cloud solution, Microsoft 365 provides powerful productivity tools and world-class security features.

Why businesses are moving to Evergreen IT
As Microsoft 365 has become integral to daily operations for millions of organisations, it’s crucial to have the right processes and roles in place for ongoing management. Cloud vendors manage updates differently, with continuous feature launches, updates, and retirements, keeping your software up-to-date, but also posing alignment challenges.
