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 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 initial setup is simple."
"The real-time editing feature is valuable."
"The valuable feature of Google Workspace is its integrated environment where everything is pre-integrated, like chat and document sharing in Gmail."
"It's a secure solution that enables you to choose those you wish to share with."
"The valuable features include the email service, email updates, and Google Drive."
"It is quite a useful tool. It allows many people to work on a document. You can actually provide review comments and tag anybody to make the comment changes. You can also attach a document in Google Chat."
"The calendar is the most valuable feature."
"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 its ease of use, excellent pricing, and it is platform agnostic."
"It's relatively simple to use."
"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."
"The user interface is good."
"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

"G Suite is not as powerful as Microsoft Office Suite, so sometimes we have to change to Excel and PowerPoint."
"There's a bit of a learning curve."
"To a degree, the project management service could be improved."
"I believe that Sheets could have a more functional and user-friendly interface. Google Sheets currently lacks macros and cross file links which can be found in Excel."
"When I compare with Office 365, G Suite has fewer features."
"Improvements to G Suite would be the ability to collaborate more easily and better quality video compression in Google Meet."
"Everything is online, so you don't have a client on your desk. Working on email is online work, so can't do work offline and go back online. Sometimes it's not so intuitive. If you answer an email, it puts your answer at the bottom of the existing email."
"With Microsoft, you can use it on the web version, and you can use Microsoft Outlook. Google has the web version."
"KerioConnect continues to improve with regular updates throughout the year. They must be added to the roadmap, which requires approval."
"It could be simpler to use and install, but I still wouldn't use it because there isn't a compelling use case."
"I would like to see better support from their support team."
"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 cannot compete with them because they're fully integrated with their applications."
"Having a native Outlook map integration would make Kerio Connect better."
"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 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."
 

Pricing and Cost Advice

"The pricing of Google Workspace, so far, has been reasonable."
"We pay on yearly basis."
"Careful consideration should be given to the different licensing options and provisions should be made for additional applications that may be required for your particular business."
"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."
"The overall cost is very reasonable when considering all of the security features that you are receiving. It is a bit more expensive than our local host and/or other hosting companies that are available on the market, but it is worth it."
"The pricing is a bit on the higher side than normal. For a basic Google account it costs $100, but Enterprise is %150."
"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."
"2,500 Rupees per month per user."
"KerioConnect has a first-time cost and yearly subscription. It is not expensive."
"The pricing is about $3 per mailbox per month."
"The price of Kerio Connect is better when comparing it to others solutions."
"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."
