Tolu Omolaja - PeerSpot reviewer
Great URL scanning and attachment scanning, but I would like more proactive threat analysis
The two main features that prove most beneficial for us are URL scanning and attachment scanning. URL scanning involves an automatic scan of links and emails. When a user clicks on a link within an email, the system promptly checks the link's safety. If the link is deemed safe, access is granted automatically. However, if it is flagged as unsafe, we receive feedback and notification to caution us about the potentially harmful link. At this point, we are presented with the option to proceed or return. I have personally witnessed the system identify a few unsafe links, making this the primary advantage of using the solution. The second crucial aspect is the scanning of attachments. When an email containing an attachment arrives, we receive a notification of the new email, along with information that the attachment is being scanned for threats. This additional layer of security provides peace of mind for our organization. While Microsoft Defender for Office 365 offers numerous features, these two stand out as particularly impressive and valuable to us.

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.

Offers comprehensive security, easy integration, and good support
It integrated easily. About 99% of the time, we do not face any challenges in integrating any product of Trend Micro with the existing network. It is usually compatible with all kinds of networks. They have recently added AI to all Trend Micro products. It makes life a little bit easier by catching viruses, providing solutions, and helping out whenever you are stuck somewhere. It is one of the very good features they have right now. For example, one of our clients experienced a network attack and became confused about resolving the issues. The AI was helpful by suggesting initial steps to solve the problem.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The DLP feature of Microsoft Defender for Office 365 is valuable, and we also use the DLP feature for email real-time detection."
"Microsoft Defender for Office 365 has improved my organization's security. It makes it easier to manage the infrastructure without the help of third-party applications."
"The ability to respond to threats if very important."
"Since we have started using the solution, there have been fewer compromises."
"Microsoft Defender for Office 365's most valuable feature is its performance."
"The benefit that stands out to me is the ability for multiple individuals to collaborate simultaneously within the same document. Additionally, there is the option to save the document directly in the integrated OneDrive or SharePoint."
"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."
"The product is not resource-intensive."
"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"The integration rate is very high in Kaspersky, which is why most of our customers like it."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"The most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."
"The most valuable feature is the straightforward setup."
"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 most valuable feature of Trend Micro Email Security is effective phishing prevention."
"The most valuable feature of Trend Micro Email Security is the security level it provides. The solution is efficient."
"The tool provides a strong defense against attacks. It is also easy to use. Trend Micro Email Security's integration capabilities are great."
"Some people can hack our system by sending emails from our domain to our domain. This is blocked completely by Trend Micro."
"Trend Micro Email Security has a feature for secure protection of OneDrive, Google Drive, and CloudApp security."
"The most valuable features of the solution are spam protection and email continuity."
"The technical support is good."
"Trend Micro Email Security is a robust solution with quick performance. It works autonomously without the need for an administrator."
 

Cons

"In the areas of improvement for Microsoft Defender for Office 365, the console is the biggest challenge for me."
"The pre-sales cost calculations could be more transparent."
"The UI needs to be more user-friendly."
"Specifically, within Microsoft Defender for Office 365, I want it to improve the DLP capabilities."
"There is a different console for different things; I just want one consolidated console."
"The phishing and spam filters could use some improvement."
"They have moved features from one console to another. Things have been moved around in the interface and it takes me time to find where certain features are."
"Configuration requires going to a lot of places rather than just accessing one tab."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."
"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."
"I have only made contact via email, and it is a little slow. I would give customer service a rating of six or seven. Improving Spanish support would greatly benefit users."
"I rated the overall solution a five out of ten. If a user is looking for a low-budget solution with mid-level security without AI features, Kaspersky Security for Mail Server is suitable."
"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."
"The product must provide better customization features."
"While they are good, not 100% of email is protected just yet."
"The tool's dashboard is old."
"Sometimes malicious email gets past the email gateway."
"I would like to see more integration of Trend Micro Email Security with different platforms."
"The enterprise security feature needs improvement."
"There needs to be more documentation for the product."
"There is a limitation when customers are using their email from a third-party solution that isn't from Trend Micro."
 

Pricing and Cost Advice

"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."

"The pricing has become expensive."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"The product is expensive."
"While Microsoft Defender for Office 365 necessitates pricier E3 or E5 subscriptions, the extensive functionality offered by these licenses across various Microsoft products justifies the investment."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."

"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."
