Useful for collaboration and storage but improvement is needed in API integration
The solution has traditional SSL integration, SAML, and Federation Services. In its latest version, it added SAML integration. However, it needs to work on API integration, especially for dashboards or integration with SAP for log and data system management. It doesn't yet have the kind of API that Google and Microsoft provide for synchronizing users with Active Directory. I think IceWarp needs to improve in a few areas. They have two types of admin consoles - a web-based one and a remote one. I'd like to see these combined into a single web-based admin console. The log reading and information system also needs improvement. The current way of showing incoming and outgoing logs isn't very clear. For new users, it's hard to understand these logs, especially compared to Office 365 and other systems with easier-to-read logs. They should also add an export option to get all logs with a single click whenever we need them.

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

"Its price is the most valuable. It is definitely one of the lowest price solutions."
"The solution's voice services work well for our company."
"An effective, functional, very good tool for controlling resources."
"The product is used very extensively in my company since we have around 1,500 users using it. Also, there is no requirement for any administrators to manage the product by the people who own the solution."
"It has great communication capabilities for team chatting and web conferences."
"IceWarp has multiple applications that are easy to use for many people."
"The solution is easy to manage and includes features such as smart documents and the archiving of user data."
"The most valuable feature of IceWarp is the chat rooms and file-sharing, they are useful. It is convenient that everything is in one place. You can easily share and collaborate documents, making the program's unity a significant advantage."
"We use the solution as a mail server. It connects with Outlook and is used for calendaring and similar tasks."
"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."
"The most valuable features are its ease of use, excellent pricing, and it is platform agnostic."
"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."
"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."
"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."
"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."
 

Cons

"I would like to have a trial for mobile applications and more documentation similar to Google Drive with mobile applications."
"The solution has traditional SSL integration, SAML, and Federation Services. In its latest version, it added SAML integration. However, it needs to work on API integration, especially for dashboards or integration with SAP for log and data system management. It doesn't yet have the kind of API that Google and Microsoft provide for synchronizing users with Active Directory."
"The solution needs improvements in security, particularly regarding document management."
"Although the documentation is extensive and in depth, you must familiarize yourself with it before taking full advantage of the product."
"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."
"Although it is not a tool, video conferencing should be scalable and operate in a professional and efficient way."
"Our customers sometimes have problems receiving mail."
"Support should be improved. Most of the time, the queries are not resolved within the SLA."
"KerioConnect is stable as long as you use a strong password."
"Having a native Outlook map integration would make Kerio Connect better."
"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."
"KerioConnect continues to improve with regular updates throughout the year. They must be added to the roadmap, which requires approval."
"You cannot integrate with other services like Google Docs, Google Assistant, Google Calendar, etc."
"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"
 

Pricing and Cost Advice

"Our licensing is on a yearly basis. There were no additional costs."
"The solution is priced well."
"The solution is inexpensive which is its main benefit."
"I would rate the pricing and eight out of ten."
"Costs far less than other solutions."
"The license is based on the number of users."
"Price-wise, it's a cheaper solution, without a doubt. Price is the reason we are still using the tool."
"It is definitely one of the lowest price solutions."
"The price of Kerio Connect is better when comparing it to others solutions."
"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 pricing is about $3 per mailbox per month."
