Jamie LeClair - PeerSpot reviewer
File-sharing options and ease of collaboration or meetings allow for quick collaborations and chats
I work in my company's IT department, so I use all of the products under Office 365 daily, including Microsoft Word, Microsoft PowerPoint, Microsoft Teams, and all the other components in the product. My company can't make it through a day or go by without using the products offered under Office 365. Some of our manufacturing workers may use Office 365 a lot less, but it is still necessary for things like Microsoft Outlook and Exchange. I found Microsoft Teams to be the most valuable feature of the solution, along with all of the products and features offered under Office 365. My organization has remote workers, and we can't run the company without meetings organized with the help of Microsoft Teams.
Taha Khaleel - PeerSpot reviewer
A highly reliable solution that provides monitoring capabilities and protection to multiple types of devices
The initial setup of Kaspersky Security for Mail Server is very easy. The initial setup of Kaspersky Security for Mail Server takes around four minutes. The solution is deployed on the cloud and on-premises. For the deployment process, you can buy the solution in a CD form or purchase it directly from the company website and activate it. My company needs managers, engineers, and developers to deploy the solution. The number of people required for the deployment process changes from time to time, so all the staff are included not just for the deployment of the solution but also to make improvements to the solution in the future. You can contact Kaspersky to see if they can provide the solution with integration capabilities for your company by providing you with an open account, which I haven't tried yet, though I plan to try it in the future.
Nur Mohammad - PeerSpot reviewer
An effective email security solution that provides DLP, Safe Attachment, and Safe Links
If you want extensive email security, you need to purchase a Plan 2 license. Plan 1 and Plan 2 are the two plans for Microsoft Exchange Online Protection. Some customers hesitate to purchase this product because it adds some costs to them, which is necessary for them. It would be helpful for customers if Plan 1 features were included with EOP. However, they still need to purchase Plan 2 for advanced security features. One of our clients recently requested to compare Zimbra's features with Microsoft Exchange Online Protection. Zimbra is open source, while Microsoft Exchange Online Protection is not. When I compare both the products, many free features are available in Zimbra because it is open-source software. It makes no sense to request Microsoft Exchange Online Protection add all the features people get on open-source software like Zimbra. Hence, I would say whatever features Microsoft Exchange Online Protection has are enough. Microsoft has a dedicated research team that should research and add new techniques like phishing and spamming solutions to the product.
