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

"IMAP works very well from all environments."
"Go for it and use it effectively."
"Extremely reliable, providing great collaboration features."
"The initial setup is simple."
"The collaboration features are valuable."
"The product is user-friendly and knows how to appeal to a user. Google Docs accepts some of our requirements. Its most valuable feature is performance. The product's integrations are good."
"The solution is stable."
"It's stable. There isn't really any downtime."
"As long as the operating is stable, the Kerio connect will be very stable as well, so we don't have any problem with it."
"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."
"We have contacted technical support a handful of times and received some assistance."
"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."
"Backing up and maintaining it is straightforward compared to Microsoft Exchange, making it administrator-friendly."
"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

"What needs improvement in Google Workspace is the Google Drive app, in particular, making the process of finding the shared and most used files and folders easier."
"Our users have faced an issue with increasing their email quotas over the last three months."
"Integration with Microsoft Outlook could be improved. The new integration was implemented last September, and we are facing some issues with OAuth 2.0 authentication."
"I talked with G Suite recently because my G Suite has a temporary block. I communicated with the G Suite representative or Google representative, and he told me that I sent a lot of emails, so my email was temporarily blocked. But I know I have not sent more than 500 emails daily to reach the limit. I sent only 5,200 emails, but unfortunately, my G Suite account was temporarily blocked for 24 hours, and then he resolved it. I think they need to improve G Suite because this temporary block is not fair."
"Scalability is not as good as we would like."
"The problem with the presentation is that if you upload a Microsoft PowerPoint presentation and you convert it to Google presentation, the slides or pictures, their images are not editable. You can't edit the slides that you brought in. They're just images."
"Google Workspace lacks the ability to copy and move files from one folder to another easily."
"In the next release, I would like to see more encryption of documents, mail, and things like that. There should be a better way to encrypt mail and documents that are pushed through this system. That would be some improvement or additional features that could be good to have."
"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."
"I don't particularly like this solution. I would not recommend this solution to others."
"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."
"The search and archiving documentation capabilities need to be stronger."
"I would like to see better support from their support team."
"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."
"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

"I give the pricing an eight out of ten, with ten being the most affordable."
"There are different versions of the solution available, such as premium."
"There are benefits that can provide a competitive advantage, e.g., improved productivity (with appropriate training), increased collaboration (with correct use of tools), flexible working - work from home or remote locations, easy to scale - fast onboarding of new employees, and ability to add and remove licenses, as required."
"2,500 Rupees per month per user."
"The pricing is a bit on the higher side than normal. For a basic Google account it costs $100, but Enterprise is %150."
"It's about $8.30 up a user per month."
"You pay for Google Workspace based on your usage and the apps you use, but in my case, it's free, but if I used it a lot more, I'd probably need to pay. 15GB is enough for me, but I see myself upgrading and paying the additional charges for more storage regularly."
"Traffic management tools may be required for larger setups and should be included in any pricing calculations."
"The pricing is about $3 per mailbox per month."
"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."
