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.
Frank Rawson - PeerSpot reviewer
It gives clients peace of mind and helps them educate their users about threats
A few years ago, our team found the implementation to be somewhat challenging. It has gotten easier as we've grown more experienced. The difficulty depends on the expertise of the person doing it. I don't work with Mimecast every day, so it might be more difficult for me than it is for one of my techs who regularly does Mimecast implementations. It requires some specific in-depth product knowledge and an understanding of email solutions. The deployment time varies. In South Africa, it depends on who you use to deploy it. If you use one of Mimecast's local partners, it can take up to two weeks because of their process. However, it's only about four to eight hours of work. After deployment, there isn't much maintenance aside from supporting and educating your customers. Users require constant education on how to use the Mimecast client and release an email that has been blocked.

Quotes from Members

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

Pros

"The most valuable feature of Microsoft Defender for Office 365 is data backups that we can provide through ticket requests."
"The product's scalability is good."
"We use Microsoft Defender for its ability to integrate with existing business technologies, which is beneficial for protecting business areas."
"The most valuable aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"Microsoft Defender for Office 365 facilitates efficient management and updates through the cloud. We do not have to worry about incompatibilities. It just works."
"Microsoft Defender for Office 365's most valuable features are safe attachments and safe links."
"At the moment we are satisfied with this product. It's a stable, scalable, and resilient solution for us."
"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 have a lot of control over spam and phishing emails."
"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."
"The solution offers good technical support."
"The integration is straightforward."
"I recommend Mimecast based on customer requirements and budget."
"The initial setup is easy."
"The piece that is most valuable from the Mimecast standpoint will be the sandboxing feature."
"URL inspection works pretty well."
"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."
 

Cons

"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 GUI is sometimes slow to fetch the device report and could be improved."
"There is room for improvement in terms of reporting."
"Several simulation options are available within 365, and the phishing simulation could be better."
"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"There's room for improvement regarding the time frame for retrieving emails."
"Configuration requires going to a lot of places rather than just accessing one tab."
"The solution’s pricing is not reasonable."
"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."
"The pricing is a little high compared to other products."
"A reduction of 10% in pricing can be an improvement."
"The filtering needs more flexibility."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"The installation is not so straightforward."
"The solution should include more AI features instead of Mimecast's more general static configuration tooling."
"The attachment scanning feature doesn't work properly."
"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."
"I did have a problem with Mimecast. That is why I was looking for an alternative solution because their sender IP address gets poorly rated by Microsoft."
"The solution is complex and not easy to use."
 

Pricing and Cost Advice

"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."
"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."
"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."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"It's a user-base subscription."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"The pricing is acceptable and falls into the medium range, neither cheap nor overly expensive."
"The product price is moderate. I rate the pricing a five out of ten."
"It's an expensive solution."
"The customers can select the license packages as per their requirements."
"I'm always going to say the price needs to be lower, but it's reasonable."
"The solution is expensive."
"Compared to the other products in the market, it is neither cheap but nor very expensive. I would rate it somewhere in the middle, 5 out of 10."
"There are additional costs beyond the standard licensing fee."
"For what it is, the product is overpriced."
