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 valuable features of this solution are ease of use, performance is great, and collaboration. It is very easy to share and joins documents."
"The most beneficial feature is Gmail, which we use extensively."
"Google integrates well with our system. G Suite has an open API, so you can connect any open system with Google capable of working with API. This is the main reason we use it."
"Only a few competitors can do precisely what Google Workspace does in terms of email management and calendar management through its Gmail and Google Calendar apps. It's a very seamless platform."
"It's a secure solution that enables you to choose those you wish to share with."
"The solution is stable."
"The collaboration features are valuable."
"Being able to back up our data on Google Drive is a critical and valuable feature for our customers. It is just in sync. Imagine you change a file on the desktop, and it gets updated directly to your Google Drive. Our laptop is completely in sync with Google Drive. Google Meet, Google Sheets, and Google Docs are also amazing products. They're very versatile and easy to use as compared to Office 365. I am using Google Sheets and Google Docs, which first save the work on my memory or ROM, and then on my RAM. It gives me better productivity through Google Sheets and Google Docs."
"It's relatively simple to use."
"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 have contacted technical support a handful of times and received some assistance."
"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."
"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 security and privacy because you installed it on your server, within your company premises, not in the cloud."
"We use the solution as a mail server. It connects with Outlook and is used for calendaring and similar tasks."
"The most valuable features are its ease of use, excellent pricing, and it is platform agnostic."
 

Cons

"I believe Google Drive has potential for improvement. Enhancements could be made in terms of synchronization and the functionality of the Google Sheets app, particularly in areas like formulas and pivot tables, to make it more comparable to Microsoft Excel. Google Chat needs to make improvements so that we can send Excel and PDFs from the mobile app itself. I would like to see Google Bard integrated with the product."
"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."
"Google could integrate Gemini AI with Google Workspace to enhance user experience."
"Less customizations than there used to be."
"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."
"The cost could be improved. It can sometimes be a bit confusing figuring out how we are actually being charged."
"If your storage requirements in day-to-day work are large, then it will incur an additional cost since free storage is limited."
"It would be a lot nicer if the default Gmail came with features that we currently need add-ons for, such as tables, automatic BCC, resizing of the panel on the left-hand side, email highlighting, and configuring the display of time and date against each email."
"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."
"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."
"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."
"KerioConnect continues to improve with regular updates throughout the year. They must be added to the roadmap, which requires approval."
"We cannot compete with them because they're fully integrated with their applications."
 

Pricing and Cost Advice

"Approximately $6 per user, per month."
"Traffic management tools may be required for larger setups and should be included in any pricing calculations."
"We have purchased an annual subscription."
"We normally purchase the license on a yearly basis."
"We receive value for the price that we pay."
"I rate Google Workspace's pricing five to six out of ten. We do not pay any extra costs."
"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."
"It's about $8.30 up a user per month."
"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."
"KerioConnect has a first-time cost and yearly subscription. It is not expensive."
