Great features that enabled us to reduce hardware at our on-prem sites

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.

Quotes from Members

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

Pros

"The solution offers great features."

"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."

"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."

"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."

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

"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."

"It's relatively simple to use."

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

Cons

"NVMe support is lacking when it comes to performance on the disk side."

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

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

"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"

"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."

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

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

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

Pricing and Cost Advice

Information not available

"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."

"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."
