Collaborative work with students has improved but storage limitations and support issues remain
We have Google Workspace, and we use it primarily for Drive to collect items. We categorize folders with topics and material either for students or for research. We use Google Doc to share documents, especially when we assign homework to be corrected for peer correction or classroom correction. With Teams and Microsoft, we use it for collective calls and exam supervision because we use video surveillance through camera with Teams. We use Teams for meetings and to share material with students. The ability to share documents with students and assign them things and correct them in real time has been beneficial. You can verify what they write, and they can contribute and cooperate to create a collective document, which is something that our society nowadays requires. The ability to cooperate, especially those who work with languages and those who work with writing, need to learn how to cooperate. There is co-editing and co-writing, all these sorts of things. I love the fact that I can easily have access to folders that I can categorize and where I can upload research material and teaching material.

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.

Quotes from Members

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

Pros

"We value the collaboration levels that are offered. Having everything integrated in a single platform is a dream come true for us."
"I like the capabilities for collaboration on any platform. For example, I might be on an iPad whereas the person next to me is on a laptop and the person next to them is on their phone. We can all collaborate together and update documentation in real-time."
"Convenient to share and collaborate documents."
"The solution is very intuitive."
"The solution's technical support is very good."
"When it comes to email, Google has a very good anti-spam engine or solution. We get very less spams. We don't have to use an external anti-spam solution with this."
"The solution offers very good email. It's a very good email provider."
"I have found the solution to be pretty stable."
"The most valuable features are security and privacy because you installed it on your server, within your company premises, not in the cloud."
"The most valuable features are its ease of use, excellent pricing, and it is platform agnostic."
"The user interface is good."
"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."
"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 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."
"We have contacted technical support a handful of times and received some assistance."
 

Cons

"The solution could improve by having more frequent updates."
"There seems to be a bit of vulnerability on some operating systems, specifically on the iPhone. There isn't as much control as if a person is using an Android. That's a bit of a concern."
"When I compare with Office 365, G Suite has fewer features."
"In Google Meet, there is no feature for recording a meeting. It should have a feature for recording."
"Google Workspace needs to be more flexible, like Microsoft Excel."
"Google Meet is a very good product, but it's not up to the mark if you compare it against other products like Zoom or Microsoft Teams."
"The downloading options need improvement, particularly in converting and viewing data formats like PST and inbox formats easily."
"And I think Google Translate could add more features. For example, it could be integrated when typing in a document or a web browser like Grammarly."
"We cannot compete with them because they're fully integrated with their applications."
"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"
"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."
"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."
 

Pricing and Cost Advice

"We pay a monthly subscription for the use of this solution."
"Pricing is something concerning. We find the solution very expensive."
"The pricing is very high, although I cannot tell if this is the result of the Indian vendors artificially inflating it."
"The pricing is reasonable."
"The price of the solution can vary."
"We have purchased an annual subscription."
"It's low in cost as compared to Office 365. There is an annual licensing cost."
"We receive value for the price that we pay."
"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."
"KerioConnect has a first-time cost and yearly subscription. It is not expensive."
"The pricing is about $3 per mailbox per month."
