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.

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.

Quotes from Members

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

Pros

"It gives us visibility into threats and, for endpoints, it helps us to prioritize threats. We used to have a lack of visibility, but now our time to detect and respond has decreased."

"There are several features that I consider valuable."

"The good part is that you don't have to configure it, which is very convenient."

"The solution is very easy to use. All you have to do is to assign the license to the end-user and it's done. The customer will only have the feature activated, and the solution will monitor the emails to determine if they are a threat or not."

"I like its investigation capabilities, as that is what is most important to me. It is fairly simple with a user-friendly interface."

"The initial setup is straightforward. You just add the license, click it, and then you can set up the rules. It is quite simple."

"It also gives the vulnerability status according to the versions you have selected. Let's say you have Google Chrome. It mentions the versions it has, and it updates. Within two hours of an update, it is reflected in the dashboard. That's really nice to have."

"The deployment capability is a great feature."

More Microsoft Defender for Office 365 pros

"The most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."

"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 features are the anti-phishing and anti-spam capabilities."

"The most valuable feature is the straightforward setup."

"It is easy to configure, easy to use, easy to add exclusions, easy to track, and easy to add anything else if you want."

"In general, my company is happy with Microsoft support...My company hasn't faced any stability issues with the solution."

"The initial setup of Microsoft Exchange Online Protection was easy."

"The threat management feature includes policies and alerts that are valuable."

"What I like most about Microsoft Exchange Online Protection is its integration with Windows, so we have one central view for all alerts and incidents."

"It is scalable."

"We can migrate seamlessly without any disruptions to our operations."

"The solution uses artificial intelligence and machine learning, so you don't need train it to detect something. The detection and response times are short. It's an excellent product."

Cons

"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."

"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."

"In one of the reports I can get the exact place where a vulnerable file resides. But for that, I need to explicitly go into the device and check. If they could include that file part in the report, without my having to go to the device itself, that would help."

"The phishing and spam filters could use some improvement."

"You should be able to deploy Defender for every subscription without the need to add servers."

"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."

"Microsoft Defender for Office 365 must improve the overall management style, including the GUI. It also needs to change the filters so that it is easy to whitelist and blacklist data."

More Microsoft Defender for Office 365 cons

"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."

"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."

"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 solution is not 100 percent stable and that can use improvement."

"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."

"I would like to get reports about vulnerable connections from our clients with information about domains, public IPs, etc. That would be highly useful."

"The tool is not 100% stable."

"The solution can be complex at times. It would be nice to have the on-server version. It needs to improve the stability as well."

"The reporting needs a little bit of improvement."

"It wasn't easy or intuitive enough for me to start using it. So, the reason was that the solution changed."

"Not all settings can be configured automatically and most still require manual configuration. However, there is an automation tool available that can be used to input all the configurations either as a script or a tool it would be helpful."

"The solution needs to improve its backup."

"The product's end-of-life cycle could be extended."

More Microsoft Exchange Online Protection (EOP) cons

Pricing and Cost Advice

"The solution could be better by simplifying the business model of their licensing. It was hard to figure out how to get the licensing done for the environment, initially."

"It's a user-base subscription."

"Defender is a little bit more expensive as compared to others. We are in the manufacturing environment. So, we don't have a high budget for all of our endpoint devices. Its cost is a major concern for us."

"For licensing, it's usually a yearly package for customers who are subscribed to Office 365, but they can also pay on a monthly basis."

"The pricing is normal. Considering its popularity, it's not overpriced."

"The product is expensive."

"The pricing has become 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."

More Microsoft Defender for Office 365 pricing and cost advice

"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."

"The solution is not expensive."

"My company makes annual payments towards the licensing costs solution."

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

"The solution should reduce the cost."

"It's a high price."

"The pricing for the solution depends on what you are trying to achieve with the use of the product, but I know that it is not a cheaply priced product. Yearly payments have to be made towards the licensing fees of the solution."

"The solution is expensive but is backed by Microsoft's reputation."

"The solution falls on the higher or more expensive side of the spectrum."

"The solution's pricing is subscription-based rather than a yearly licensing cost. Pricing is based on the size of the environment and company and can be expensive."

"The product is bundled with Microsoft 365."

"Apart from the license fee for the solution, there are no additional costs."
