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.

Enhances email security and has a very simple and easy-to-use UI
Spam protection is the most valuable feature. We have implemented the tool to enhance our email security. It helps prevent phishing attacks. The anomaly detection capabilities are baked into the security platform. The product integrates wonderfully with Microsoft 365. It's built right on a cloud platform and works almost natively. The solution has a very simple and easy-to-use UI. The tool appears extremely powerful and has a good solid feature set. It catches things that are bad for my environment. The user interface is good the way it is. If the solution continues down that path, I see no problems with the way it is going. It feels like a mature product.

Handles security, malware and spam of email systems
We use Email Security Gateway on email systems for handling security, malware, and spam.  The solution is easier to manage than FortiMail. You can implement policies easily.  The solution does not always effectively identify zero day spam and phishing, but once reported the correction occurs very…

Quotes from Members

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

Pros

"Our customers are satisfied with Defender for 365 because Microsoft products are easy to use and customize to meet the client's needs. Everything is in one place, so we can adjust policies as needed for phishing, DLP, ATP, or any other security features that our clients want to apply."
"My experience deploying Microsoft Defender for Office 365 was seamless."
"Microsoft Defender for Office 365 is a stable solution."
"It has significantly decreased my time to detection and response."
"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."
"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."
"It’s easy to handle integrations, and we don't need a lot of people in our IT team."
"At the moment we are satisfied with this product. It's a stable, scalable, and resilient solution for us."
"Easy to use for non-technical users."
"The threat detection tools enable us to ascertain malware and phishing messages across the email network infrastructure."
"The ease of installation and the AI capacity of the product are valuable."
"It is simple to deploy this platform and interact with the set features."
"This technology is one of Check Point's acquisitions, and it is currently a powerful tool that provides all the protection that is not found in other tools."
"Avanan is a stable software. My company hasn't faced any issues, bugs, or problems with the performance of Avanan."
"The most valuable feature of Avanan is its Anti-Malware solution for Office 365, and box.com."
"Spam protection is the most valuable feature."
"It helps reduce spam and phishing attacks."
"The solution is easier to manage than FortiMail. You can implement policies easily."
 

Cons

"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."
"We are always looking for others tools to increase automation on tasks. There can be better integration with other solutions, such as PowerPoint and email."
"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 pre-sales cost calculations could be more transparent."
"We need a separate license and we don't know how to get the license that is required."
"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."
"There's room for improvement regarding the time frame for retrieving emails."
"They can improve their security in a way where a customer can know if all their attachments are safe or not to open through a report. The solution does its job perfectly, but it never reports to the customer whether those attachments have been stopped before or not."
"The user experience must be improved."
"Being cloud first and because we are in the movie business, we use a lot of Macintoshes. So, there is absolutely no reason for us to have Active Directory whatsoever. However, if you are using Office 365, you must have Active Directory in order to reset passwords. Even though we have a single sign-on provider, we must have Azure Active Directory for Office 365, which is really stupid. As a cloud application, you would think that I don't need Active Directory, which I don't need for anything else except Office 365. We have one server inside that space to help us manage Active Directory just for Office 365. This is a very sore point, but it is what it is."
"Integration with various SaaS offerings, who are leading in the SaaS market."
"It is complicated for new users unfamiliar with the modern cloud networking infrastructure."
"It should reduce the amount of time needed for thorough scanning."
"It should also offer a quick backup in case any email is wrongly quarantined or deleted to ensure no data loss."
"The customer service team could come up with clear tutorials on how to use this platform to help new teams."
"When sending bulky emails, the system slows down and takes a long time before it responds effectively to our requests."
"Its pricing could be affordable."
"The solution does not always effectively identify zero day spam and phishing, but once reported the correction occurs very quickly."
 

Pricing and Cost Advice

"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"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."
"The pricing is normal. Considering its popularity, it's not overpriced."
"The product is expensive."
"The license is expensive because the cost is based on the number of users."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"Having the flexibility and modeling to do the pricing that best fits the needs of the organization is incredibly ideal. That is what Avanan does. They know exactly how many users are using it, etc. We can tune the invoicing associated with how we are using the product so we can charge it back to the shows appropriately."
"Avanan’s price is comparable to Barracuda."
"Good pricing arrangement as an SaaS offering."
"The pricing of Avanan is reasonable."
"The product is not the cheapest in the market."
