Why Businesses Migrate Emails from Kerio to Gmail?

Startups and mid-sized companies choose Kerio Connect for its low cost and simple management. But, as the team grows, Gmail emerges as the most preferred platform. Take a look at why:

Gmail’s cloud infrastructure is designed to handle the increasing number of mailboxes without slowdowns.
Unlike Kerio Connect, Gmail hosts everything securely in the cloud. Kerio Connect involves paying for servers, storage, and more.
By migrating to Gmail, users can utilize Gmail’s suite of productivity and collaboration tools.
With Gmail, users can access their emails from any device, eliminating the location barriers.
The Gmail email client offers enterprise-level security with advanced filtering options, preventing data leaks.
