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 stability of Google Workspace is excellent and very solid."
"The solution offers very good email. It's a very good email provider."
"Google Chat is the most valuable feature of the solution."
"Google Meet is the most valuable function for me. It has enhanced collaboration in our team."
"I use Keep to assign tasks to a team of programmers, which is very easy."
"The document sharing in which multiple people can work on the same document. To go along with that is the archiving of documents. If you mess up a document, it's easy to go get a previous version."
"The solution offers a workflow where we can collaborate and share documents. Its most valuable features are Gmail and Google Drive. Google Drive is great for file collaboration. It improves productivity. The product is on the cloud; we don't have to connect to the office through a VPN."
"G Suite is a powerful suite of tools for messaging and collaboration that has met the fundamental needs of my company, both increasing productivity and reducing costs."
"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."
"We have contacted technical support a handful of times and received some assistance."
"The user interface is good."
"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."
"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."
"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

"G Suite could offer something a little more solid in terms of chat — something that is a little more like Slack and integrates with everything. But, unfortunately, the chat is very basic there. It doesn't offer that many features and feels like it doesn't belong there."
"Google Workspace does a pretty good job, so it doesn't have that much room for improvement, but what would make it even better is if its apps, for example, Gmail, could integrate with more apps, such as Evernote and specific cloud-based platforms."
"Improvements to G Suite would be the ability to collaborate more easily and better quality video compression in Google Meet."
"The only inconvenience is the fact that you have limited storage. After a while, you have to buy a surplus."
"G-Suite is excellent for what we're trying to do, but it could use some extra features. For example, it would be helpful if we had a seamless way to convert Excel macros to Google Sheets."
"We would like to use something within Google Workspace for project management, but we didn't find it there."
"The performance speed could be improved when the internet connection is slow."
"I have had issues with my Google Address Book. I have an address book and it is available to everyone, but I cannot add additional users. In Microsoft Outlook, I could easily share certain contacts with other members of my team, but I cannot do so on G Suite."
"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."
"The search and archiving documentation capabilities need to be stronger."
"I would like to see better support from their support team."
"It could be simpler to use and install, but I still wouldn't use it because there isn't a compelling use case."
"You cannot integrate with other services like Google Docs, Google Assistant, Google Calendar, etc."
"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 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"
"KerioConnect is stable as long as you use a strong password."
 

Pricing and Cost Advice

"The pricing is reasonable."
"G Suite and Microsoft Office 365 offer products with similar functionality at several different price points. Zoho offer a more extensive range of products and attempts to provide all the applications required to run most small and medium-sized businesses."
"2,500 Rupees per month per user."
"We receive value for the price that we pay."
"The pricing is comparable, it's pretty decent."
"I can't recall the exact pricing per user for Google Workspace, but I know it's not that expensive. I'm in a mid-sized company that's able to maintain and afford Google Workspace, so it has competitive pricing, and I would rate its price as four out of five."
"It's cheaper to run a couple of users in a Google platform than what it would be with Microsoft Exchange."
"We normally purchase the license on a yearly basis."
"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."
"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."
