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

"The most valuable features are security and privacy because you installed it on your server, within your company premises, not in the cloud."
"Backing up and maintaining it is straightforward compared to Microsoft Exchange, making it administrator-friendly."
"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."
"We use the solution as a mail server. It connects with Outlook and is used for calendaring and similar tasks."
"The most valuable features are its ease of use, excellent pricing, and it is platform agnostic."
"This solution is our SMB alternative to Exchange, installed for more than forty SMB customers in a Linux environment with all of the collaboration features."
"Kerio Connect is secure, flexible, and easy to control from the user interface."
"It's relatively simple to use."
"The best feature about Superhuman is the fact that you don't have to manually go through your emails, as this solution segregates your email according to your preferences and how you want to categorize emails."
"It is a productivity-driven email software that is fast, increases your productivity, and cuts down the time you spend compared to traditional email software."
"It is fast, and it increases your productivity."
 

Cons

"We cannot compete with them because they're fully integrated with their applications."
"KerioConnect continues to improve with regular updates throughout the year. They must be added to the roadmap, which requires approval."
"Having a native Outlook map integration would make Kerio Connect better."
"KerioConnect is stable as long as you use a strong password."
"The search and archiving documentation capabilities need to be stronger."
"Most of our clients use Outlook and Kerio Connect. Occasionally, Kerio can be a bit slow."
"I don't particularly like this solution. I would not recommend this solution to others."
"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."
"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

"KerioConnect has a first-time cost and yearly subscription. It is not expensive."
"The price of Kerio Connect is better when comparing it to others solutions."
"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."
"The pricing is about $3 per mailbox per month."
"It is fairly expensive. They have monthly and yearly licensing options."
