David Bloomer - PeerSpot reviewer
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.

Siddharth Mallya - PeerSpot reviewer
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."
"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."
"The most valuable features are its ease of use, excellent pricing, and it is platform agnostic."
"It's relatively simple to use."
"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."
"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."
"The most valuable features are security and privacy because you installed it on your server, within your company premises, not in the cloud."
"The user interface is good."
More KerioConnect pros
"It is fast, and it increases your productivity."
"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."
 

Cons

"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."
"It could be simpler to use and install, but I still wouldn't use it because there isn't a compelling use case."
"Having a native Outlook map integration would make Kerio Connect better."
"You cannot integrate with other services like Google Docs, Google Assistant, Google Calendar, etc."
"I would like to see better support from their support team."
"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 is stable as long as you use a strong password."
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 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 price of Kerio Connect is better when comparing it to others solutions."
"It is fairly expensive. They have monthly and yearly licensing options."
