Kerio Connect
On-premises email, calendar and contacts for small and mid-sized organisations.
Kerio Connect — on-premises email, calendaring and contact server for SMBs
Many small organisations need to keep email and groupware services on-site for policy, legacy systems or budget reasons. They still require calendaring, contacts and mobile access, but do not always have large IT teams to run complex messaging platforms.
Kerio Connect supplies SMTP/IMAP/POP mail services with calendaring, contacts and device synchronisation. It lets administrators manage users, policies and connectors while standard mail clients and mobile devices continue to work with familiar protocols.
Where Kerio Connect is used
Host core messaging for a single office or a small estate where cloud email is unsuitable, keeping mail on local servers and integrating with local directories or backup tools.
Used by resellers and managed providers as a lower-cost messaging option, or by internal teams that need simple calendaring and contact sharing without large infrastructure demands.
Fits within these solutions
Suitable environments
Best for small to medium estates with straightforward identity setups and a preference for on-premises control. It fits organisations with limited IT staff and modest regulatory pressure, rather than large, highly regulated estates needing complex integrations or active-active clustering.
