Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"The most valuable feature is the straightforward setup.""The most valuable features are the anti-phishing and anti-spam capabilities.""You can install the plugins on the same machine hosting your exchange solution. It's a good complement for Sophos security, which scans the traffic before it reaches your mail service. Kaspersky is on the mail server itself while Sophos handles the incoming traffic. With both of them working together, we have the perfect solution for mail.""The integration rate is very high in Kaspersky, which is why most of our customers like it.""The most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."

"Microsoft Defender for Office 365 is a stable solution.""I would say that 90% of the spam and phishing attack emails get blocked right off the bat.""Microsoft Defender has a feature to protect each and every attachment. Even if it's an encrypted attachment, it will check for any potential threats.""Threat Explorer is an invaluable tool for me, and it plays a crucial role in helping me discern the origins of various email campaigns, pinpointing where they emanate from, and identifying the individuals within our organization who are affected.""The most valuable feature is the integration. It's a single console, so we don't have to switch around between multiple products. Another valuable feature is the ease of operations and maintenance.""Defender is a SaaS platform, so it offers more flexibility. Managing the permissions is easier. The solution's automated detection and response features are scalable.""Defender helps us prioritize threats across our organization.""Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."

Cons
"The solution is not 100 percent stable and that can use improvement.""The biggest problem in the solution is related to its license renewal since it is pretty hard in Kaspersky to find out the procedure to renew a license.""Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on.""It would be great if Kaspersky could do what Sophos does for us. However, we love having these two different technologies doing the same thing. Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't.""Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."

More Kaspersky Security for Mail Server Cons →

"The custom alerts have to improve a lot.""One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration.""Microsoft Defender for Office 365 should be more proactive.""There is room for improvement with the UI.""Microsoft Defender for Office 365 could improve by giving customers information on techniques to prevent threats. For example, information about best practices on how to protect their own devices against hackers and scammers, such as educational information or training. This would help others have a better understanding of cyber security. Additionally, there can be more security features added.""Configuration requires going to a lot of places rather than just accessing one tab.""There is room for improvement in terms of reporting.""It would be better if it were more scalable. It depends on the architecture, but we would like to make it more scalable for both data centers."
