Lightweight, simple, and robust; easy to maintain and doesn't require a lot of system resources to run

Kerio Connect does as advertised, so there are no real issues with the product itself. It's developed regularly, so there are constant updates. Possibly, the support and development have lessened since they've sold the company, but as far as the product itself is concerned, there isn't anything that I would suggest needs improvement. If I'm being picky, Kerio Connect uses a proprietary, mappy atom for Outlook, and it would be nice if they used a native mappy connection instead, but that's the only additional feature that I would like to see in its next release. If they have native Outlook map integration, that would be great, but other than that, it's got all the functions that I think a mail server should have.

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

"Kerio Connect is secure, flexible, and easy to control from the user interface. It has many security features able to be controlled from one place, such as anti-spam. I have found it very convenient. Additionally, you can analyze log files and share folders which is helpful."

"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."

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

"We have contacted technical support a handful of times and received some assistance."

"The user interface is good."

"The solution is easy to maintain, unlike Exchange. It's easy to create multiple domains and back up and restore if needed. It also has good security features like anti-spam and antivirus."

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

"Having a native Outlook map integration would make Kerio Connect better."

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

"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"

"KerioConnect continues to improve with regular updates throughout the year. They must be added to the roadmap, which requires approval."

"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."

"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."

"KerioConnect is stable as long as you use a strong password."

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

More KerioConnect cons

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

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

Pricing and Cost Advice

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

"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."

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