ProtonMail vs Zimbra Collaboration comparison

"What I appreciate most about ProtonMail is that they are trusted, which is why I choose them."

"The auto encryption of attachments is valuable."

"The configuration is simple."

"The most valuable feature is sending messages as well as text and documents. It's a big solution for us since internal communication is a must in our organization."

"Zimbra Collaboration's best feature is its compatibility with Microsoft's ActiveSync protocol, which allows users to use Outlook on Windows or MacOS."

"The solution is easy to implement."

"The product is easy to set up."

"Zimbra Collaboration is light to manage. It works on the Linux operating system, which is far better to manage than Microsoft Windows. Microsoft Exchange works only on the Windows server. We prefer working on the Linux server for security reasons and ease of management. Zimbra Collaboration also has some integrated tools for security. It some modules to fight malware. These modules are not very powerful but are still doing a great job. Microsoft Exchange doesn't have a basic module. You have to purchase a security solution and add it to the solution. The cost of Zimbra Collaboration is one more reason for liking it. It is also very simple to migrate from Zimbra Collaboration to another email solution."

"The web interface is powerful and easy to use."

"Good email solution and it's open-source."

"I think it is good but I feel that only tech-savvy people use ProtonMail. It is not that popular among other people."

"One improvement could be the integration between ProtonMail and Proton Pass, allowing sharing of specific secrets via email."

"The solution could improve by making it easier to use."

"The installation is not straightforward, it can take two days for the full implementation."

"Some issues cause the solution not to function correctly or to cause downtime once a month."

"The solution could use more integration with third-party tools."

"We have had an issue with security."

"Zimbra Collaboration does not have a solution roadmap as aggressive as the new collaboration mail solutions. Additionally, they can have a better interface and integration with single sign-on."

"Zimbra Collaboration could improve the migration from a basic solution to a more containerized solution. For example, the installation should be able to extend to the containers and manage them with some solution, such as OpenShift or Kubernetes."

"Zimbra Collaboration's video conferencing could be improved."

"The solution is competitively priced."

"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."

"When it comes to the licensing of Zimbra Collaboration, my license covers the servers and I find its terms to be much simpler than those of Microsoft Exchange."

"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."

"The price of the solution is low."

"The solution is not expensive compared to other products."

"It's very expensive. When we compare the cost with Google Workspace, it's so expensive."
