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.

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.

Quotes from Members

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

Pros

"The initial setup was easy."
"It has significantly decreased my time to detection and response."
"The ability to respond to threats if very important."
"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."
"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"The deployment capability is a great feature."
"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."
"Microsoft Defender for Office 365's most valuable feature is its performance."
"If we look at four to five years ago, we had close to six or eight people click a link in an email per month. Now, we are probably down to about five or six clicks a year, if not less."
"Email encryption enhances end to end security of any data before it passes through the networking system."
"Easy to use for non-technical users."
"It can detect corrupted files and filters out documents with viruses."
"The ease of installation and the AI capacity of the product are valuable."
"It can retract unsafe emails and remove them from the entire communication channel."
"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."
"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."
 

Cons

"I'd like some additional features any product can give me to protect our environment in a better way."
"Microsoft Defender for Office 365 should improve the troubleshooting tools. It's unclear whether the device is blocked at the firewall level or at the device itself. The granularity needed for troubleshooting is currently lacking. From my perspective, Microsoft should address this issue to benefit many users who likely share the same sentiment."
"Too many false positives and lacks an accurate capability to detect malicious SharePoint sites."
"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"There's room for improvement regarding the time frame for retrieving emails."
"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."
"Microsoft Defender for Office 365 should be more proactive."
"Sometimes it seemed like the allow list wasn't working. I've created many allow list rules however, they still seem to be blocked; the same is true with the blocked list rules."
"When sending bulky emails, the system slows down and takes a long time before it responds effectively to our requests."
"It should reduce the amount of time needed for thorough scanning."
"It is complicated for new users unfamiliar with the modern cloud networking infrastructure."
"It is very difficult to find the required documentation."
"The system could be designed to give corporate emails first priority due to demands."
"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."
"The user experience must be improved."
"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."
 

Pricing and Cost Advice

"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."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"The product is expensive."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"The pricing has become expensive."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"Good pricing arrangement as an SaaS offering."
"The product is not the cheapest in the market."
"The pricing of Avanan is reasonable."
"Avanan’s price is comparable to Barracuda."
"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."
"The solution provides affordable pricing for medium sized industries."
