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.

A stable product that provides security and control over spam and phishing emails
I have a lot of control over spam and phishing emails. I can monitor and manage it from Hornetsecurity’s console. The live tracking system is valuable. We can track every incoming and outgoing email live. We can decide whether to block, release, or quarantine emails. We can also review the emails before releasing them. The product provides 99.9% coverage for email security.

Provides valuable security features and has a straightforward setup process
The initial setup process is straightforward and takes a weekend at most. A .com domain can take up to forty-eight hours, while a local domain takes about four to eight hours because it has to propagate through the international DNS records. It is a cloud-only solution. If you're managing email security on-premises, you use your bandwidth to download emails, including spam, and then use your servers to clean it up. For example, say a third of your email is spam; this consumes significant bandwidth and resources. However, if you use Mimecast, they filter the emails on their servers before delivering them to you. It can be a major selling point in regions with expensive bandwidth, such as Africa. You can save bandwidth and improve overall efficiency by offloading the spam filtering to Mimecast.

Quotes from Members

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

Pros

"Microsoft Defender for Office 365's most valuable feature is its performance."
"It has significantly decreased my time to detection and response."
"The initial setup is straightforward. You just add the license, click it, and then you can set up the rules. It is quite simple."
"Overall, I would rate Microsoft Defender for Office 365 at a ten."
"The most valuable feature of Microsoft Defender for Office 365 is data backups that we can provide through ticket requests."
"The deployment capability is a great feature."
"The initial setup was easy."
"Defender enables us to secure all 365-related activity from a single place. It gives us visibility into everything happening in Outlook, protecting us against phishing and other email-based threats. Defender helps us detect any suspicious behaviors."
"Hornetsecurity 365 Total Protection is an easy-to-use solution."
"The best part is, I rarely have to access the portal as everything is set up and tweaked the way I wanted it. But the feature set is incredibly granular and allows for deep levels of customization."
"Backup and restore are precious features."
"I have a lot of control over spam and phishing emails."
"Due to our specialized use case, that HIPAA dictionary really comes in handy."
"The solution offers good technical support."
"I recommend Mimecast based on customer requirements and budget."
"It's good, it keeps the spam out."
"Email security is the most valuable feature of the solution."
"The biggest advantage of Mimecast Email Security is its spam filtering. Its filtering feature is interesting."
"The solution is pretty straightforward to use and easy to set up."
"The integration is straightforward."
 

Cons

"The XDR dashboard has room for improvement."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"Microsoft wants its well-paying customers to finish testing some of its half-baked products, find bugs, and report bugs back to Microsoft's team, which is a little frustrating for those who have to manage it and roll it up to thousands of people across the organization."
"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."
"The visibility for the weaknesses in the system and unauthorized access can be improved."
"We need to be able to whitelist data at the backend."
"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 UI needs to be more user-friendly."
"The solution’s pricing is not reasonable."
"A reduction of 10% in pricing can be an improvement."
"The pricing is a little high compared to other products."
"I guess I would say maybe quick access to training material for end-users. I know partners have access to this but I as an end-user do not have immediate access to new update information."
"From an administrative point of view, Mimecast is a little bit cumbersome and difficult. It's not something that the end-user can easily find navigate themselves."
"While it's quick and easy, the initial setup could be more user-friendly."
"The detection rates are an area for improvement."
"The solution's console interface was recently changed for the admins, but the previous one was much better because we could open tabs on it."
"The solution should include more AI features instead of Mimecast's more general static configuration tooling."
"The reaction time between a new threat being identified and Mimecast picking it up needs to be narrowed a bit."
"Many of our users complain that the system is blocking too many attachments. It's a good practice from a security perspective, but our users think Mimecast is doing too much. It might be something we'll have to adjust."
"I'd like to have better support from the product in the future."
 

Pricing and Cost Advice

"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"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."
"The license is expensive because the cost is based on the number of users."
"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."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"The pricing is acceptable and falls into the medium range, neither cheap nor overly expensive."
