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.

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."
"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."
"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."
"It also gives me good visibility because, with Defender, I'm using a Microsoft product to defend Microsoft products. The integration was really seamless and I have wide visibility because it picks up almost everything. Literally, I can see almost every activity that happens, from the e-mail to the workstation itself."
"Microsoft Defender for Office 365 is a stable solution."
"One of the best features of the tool is its capability to aggregate insights from different workloads, basically from the Office 365 and endpoints part."
"Does a thorough job of examining email and URLs for malicious content."
"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."
"We are close to having 99% or 98% detection."
"The most valuable features are the precision of detection and the level of customization of the policy."
"We use the solution in all our environments. We use it for remedy tickets and give them updates. It was our main communication point."
"We use the solution to receive emails. We do not use the calendar function as our clients are slow adaptors to the latest features."
"Microsoft Exchange Online Protection has features like DLP (data loss protection), Safe Attachment, and Safe Links."
"It provides security to both on-premises and Azure infrastructures."
"It is scalable."
"The threat management feature includes policies and alerts that are valuable."
"It is an easy solution."
"We can migrate seamlessly without any disruptions to our operations."
 

Cons

"The phishing and spam filters could use some improvement."
"About eight months ago, we started to measure the quantity of phishing and spam that we have been receiving, and it has been increasing a lot. That means that protection for our email is not as good as we were expecting."
"Configuration requires going to a lot of places rather than just accessing one tab."
"The product must provide better malware detection."
"One area for improvement is integration. For example, when it comes to external SaaS platforms, we were not able to get a lot of information on integrations with such apps for security and authentication."
"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."
"There is room for improvement in terms of reporting."
"The XDR dashboard has room for improvement."
"It's not easy for an admin to check and decide if the email is good or not."
"The specific domain file for Apache needs to be well-defined."
"They should specify the difference between Defender for Office 365 and Exchange Online Protection."
"The security features could be better."
"The solution lacks to elaborate on its spam policies."
"The security compliance features need to be improved. Sometimes, a client's mailbox becomes full because of retained information and not because of mail. I would like to see improvement in block rules as well."
"Our company faces difficulty with Microsoft Exchange Online Protection (EOP) because it's too big, clunky, and difficult for a small client to implement quickly and easily."
"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 price of Microsoft Exchange Online Protection could be reduced to make it more competitive."
"Some features, like encryption, are not available."
 

Pricing and Cost Advice

"The product is very expensive."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"The product is expensive."
"I know that the product is incredibly expensive."
"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."
"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."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"The solution provides affordable pricing for medium sized industries."
"The solution should reduce the cost."
"The solution is priced high and could be less expensive compared to other solutions."
"On a scale of one to ten, where one is cheap, and ten is very expensive, I rate the pricing a six. For licensing, we can make monthly or yearly payments. Right now, we pay 5 USD per month to secure a person's license."
"Online Protection is fairly expensive."
"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 pricing of the solution is reasonable."
"The product's pricing is competitive for the US market."
"The solution falls on the higher or more expensive side of the spectrum."
