A seamless setup ensures smooth communication with comprehensive support

We remain a partner with Sophos and use XG S Firewalls without AWS implementation. We only use Sophos endpoint and Sophos Central. We host some clients on-premise while others we host remotely. The VPN connection is easy and proprietary, so it's not open to any other VPN clients. Communication with other mail servers is seamless. It can communicate with Gmail and Outlook without issues, provided the DNS settings are correct. We monitor our servers and security logs, implementing GeoIP blocking. We frequently block China and India IPs due to brute force attacks on our servers. We have extensive experience with KerioConnect. Backing up and maintaining it is straightforward compared to Microsoft Exchange, making it administrator-friendly. On a scale of 1-10, this solution rates an 8.

Email triage solution that actions and handles emails based on preferences

Superhuman could be improved by being made available across a broader range of devices including Android and Windows PCs. Superhuman is also a phone app, which is available only on DiOS right now. Because it's not available on Android, you have to use Gmail for your phone, and use Superhuman for your desktop. The search feature could be improved. Currently, Gmail search is a lot more robust because you can filter results based on your requirements. Superhuman does not offer this way of searching which can make emails difficult to find.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"KerioConnect has integration with 365. We can use Outlook, which has its client and can be used with Apple devices. It integrates with the App Store and Microsoft Office. It has a smart router. The spam filtering and antivirus are good."

"It's relatively simple to use."

"The most valuable features are its ease of use, excellent pricing, and it is platform agnostic."

"The user interface is good."

"The most valuable features are security and privacy because you installed it on your server, within your company premises, not in the cloud."

"We use the solution as a mail server. It connects with Outlook and is used for calendaring and similar tasks."

"What I like most about Kerio Connect is that it supports ActiveSync, and that is its most critical feature. The solution is also a nice, simple, robust, and stable mail server."

"Backing up and maintaining it is straightforward compared to Microsoft Exchange, making it administrator-friendly."

More KerioConnect pros

"The best feature about Superhuman is the fact that you don't have to manually go through your emails. This solution segregates your email according to your preferences and how you want to categorize emails."

"It is fast, and it increases your productivity."

Cons

"The search and archiving documentation capabilities need to be stronger."

"We are considering switching to Microsoft Exchange. One reason is that it doesn't improve our workflow and doesn't integrate well with Microsoft 365 applications."

"It could be simpler to use and install, but I still wouldn't use it because there isn't a compelling use case."

"I would like to see better support from their support team."

"Most of our clients use Outlook and Kerio Connect. Occasionally, Kerio can be a bit slow. They could make it faster to get onto the web interface without so much load time. It's just slow with Outlook, however, for some reason."

"You cannot integrate with other services like Google Docs, Google Assistant, Google Calendar, etc."

"We cannot compete with them because they're fully integrated with their applications."

"The solution could improve the redundancy because we only have one copy of the Kerio Connect server on our hardware. The next step for us is to move to the cloud and if Kerio does not have a cloud version available they should release one"

More KerioConnect cons

"Superhuman could be improved by being made available across a broader range of devices including Android and Windows PCs."

"It can have a few more integrations. As far as I know, it is being integrated with Salesforce."

Pricing and Cost Advice

"The solution's pricing depends on how long you plan to keep it because you pay on a per-year basis. You might have a one-time setup cost for something like Microsoft Exchange or a Linux mail server. I'd say this solution is expensive on a per-year basis, almost 2000-3000 dollars annually. It doesn't seem to pay off yet, so we're considering switching to another product."

"KerioConnect has a first-time cost and yearly subscription. It is not expensive."

"The pricing is about $3 per mailbox per month."

"The price of Kerio Connect is better when comparing it to others solutions."

"It is fairly expensive. They have monthly and yearly licensing options."
