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.

Great protection, good privacy, and helpful support
The only thing I would like is a way to open the email that is going to quarantine. Based on the level of security, they cannot open the email to check the message. Even for the administrator, you have to create a security copy to be sent, which will lock the log support. It's not easy for an admin to check and decide if the email is good or not. That is the only thing that I'm seeing could be improved. Basically, ESET doesn't have the ability to let the administrator release an email showing the message on the email. It's not possible. If you want to have an email review, you have to select an option to send a copy. In the way that they designed the system, for security, they are not letting anyone even have the admin privileges to make this happen. Privacy is at a really high level.

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.

Quotes from Members

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

Pros

"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"There are several features that I consider valuable."
"Microsoft Defender for Office 365's most valuable feature is its performance."
"The initial setup was easy."
"The basic features are okay and I'm satisfied with the Defender."
"We use Microsoft Defender for its ability to integrate with existing business technologies, which is beneficial for protecting business areas."
"Microsoft Defender for Office 365 helps people to work remotely. It is a secure solution. We don't need to use our company's computers or get VPN connections to the networks. I can control how they share screens and what they send to the devices. It keeps our organizations confidential and sensitive information safe."
"The risk level notifications are most valuable. We get to know what kind of intrusion or attack is there, and we can fix a problem on time."
"The most valuable features are the precision of detection and the level of customization of the policy."
"We are close to having 99% or 98% detection."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"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."
"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."
 

Cons

"The visibility for the weaknesses in the system and unauthorized access can be improved."
"I'd like some additional features any product can give me to protect our environment in a better way."
"Configuration requires going to a lot of places rather than just accessing one tab."
"We need a separate license and we don't know how to get the license that is required."
"There is room for improvement in terms of reporting."
"Configuration at the mid-level could be improved for the support team."
"We noticed that from time to time, Microsoft's stability does have problems. Sometimes the service goes up and down. Sometimes they change without prior notice."
"The only thing they should improve is the licensing model. They should stop changing it. A year ago, the five features I mentioned were included in one product. Now, three of them are bundled into one product, and you have to pay extra for the other two. I don't mind paying extra, but I don't want them to change it every year or every six months. I need to know what I'm looking at and not worry about it next year."
"The specific domain file for Apache needs to be well-defined."
"It's not easy for an admin to check and decide if the email is good or not."
"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."
"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."
"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."
"The solution is not 100 percent stable and that can use improvement."
"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."
 

Pricing and Cost Advice

"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"The pricing is normal. Considering its popularity, it's not overpriced."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"The product is very expensive."
"I know that the product is incredibly expensive."
"The pricing has become expensive."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"Defender for 365 comes in various plans and licenses, along with other Microsoft security solutions. Purchasing this kind of package or security bundle gives good value for money, and that's what I recommend."
"The solution provides affordable pricing for medium sized industries."
"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."
"The solution offers one of the best prices possible to its users, making it even better than Barracuda. Kaspersky Security for Mail Server is ten times cheaper than Barracuda."
"My company makes annual payments towards the licensing costs solution."
"The solution is not expensive."
