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

"The most valuable features are the speed at which G Suite Enterprise works."
"Good performance, even on relatively slow connections; no local apps required."
"The features we use quite a lot are the mail and Google Drive. We can store documents and share documents between both employees here, locally in Sweden, and we have an office in the US as well. It's a very easy way to share information and documents, and have online meetings and stuff with Google Meet. We use it quite a lot."
"Overall, I rate Google Workspace a ten out of ten."
"I find smart sheets in Google Sheets to be useful."
"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."
"G Suite Enterprise provides many features, such as business increased search visibility, email address, and domain. It's a large whole ecosystem that is the major benefit. You can manage your whole team and have many tools. Over seven years, the solution has gone through some drastic upgrades and improvements which are done automatically, I do not have to manual upgrade."
"The user interface is 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."
"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."
"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."
"Backing up and maintaining it is straightforward compared to Microsoft Exchange, making it administrator-friendly."
 

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. The first time you get an invite to view a file or folder in Google Drive and you view that folder or file, it's pretty easy, but the next time you try to access it again, sometimes, it's a bit difficult to find what was shared with you. An additional feature I'd like to see in Google Workspace is the option to un-send messages in Gmail. Microsoft has a message recall feature, and this isn't available in Gmail, so it's the feature I'd like to be added to Gmail."
"The downloading options need improvement, particularly in converting and viewing data formats like PST and inbox formats easily."
"Their tool called Sheets is the counterpart to Excel but it doesn't have the same functionality that Excel would have. So usually if somebody needs to go back to Excel or Office, it's because of Excel."
"I am not a big fan of how Gmail organizes the mail. I find it complicated to see which mail from which users send at which date. Especially if there is a lot."
"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."
"Our users have faced an issue with increasing their email quotas over the last three months."
"I would rate the stability a five out of ten."
"Google Mail's spam filter needs improvement. If I'm sending mail to another email user, sometimes it goes to the spam folder, and they won't know unless they check because they aren't seeing it in the primary inbox. They may miss important emails. At the same time, I'm receiving spam that shouldn't go to my inbox."
"You cannot integrate with other services like Google Docs, Google Assistant, Google Calendar, etc."
"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."
"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 would like to see better support from their support team."
"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"
"We cannot compete with them because they're fully integrated with their applications."
 

Pricing and Cost Advice

"It's cheaper to run a couple of users in a Google platform than what it would be with Microsoft Exchange."
"There are several areas where a G Suite implementation can reduce costs: lower license fees than some competing products, reduced hardware, and IT support costs."
"The price of Google Workspace is reasonable. I pay less than 100 a month."
"We receive value for the price that we pay."
"The price per client within the business is too high."
"The price of G Suite Enterprise is reasonable compared to HotSpot. I'm not going to say G Suite Enterprise is affordable. It's valuable, you find value in paying your gas bill or your electricity bill, because of what it allows you to do."
"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."
"The pricing of Google Workspace, so far, has been reasonable."
"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."
"KerioConnect has a first-time cost and yearly subscription. It is not expensive."
"The price of Kerio Connect is better when comparing it to others solutions."
