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.

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

"Defender for Office 365 has helped eliminate having to look at multiple dashboards and that is the aspect I like most about it. It is simpler, effective, and convenient. The users like the process efficiency."
"Threat Explorer is an invaluable tool for me, and it plays a crucial role in helping me discern the origins of various email campaigns, pinpointing where they emanate from, and identifying the individuals within our organization who are affected."
"Since we have started using the solution, there have been fewer compromises."
"Microsoft Defender for Office 365 helps people to work remotely. It is a secure solution. We don't need to use our company's computers or get VPN connections to the networks. I can control how they share screens and what they send to the devices. It keeps our organizations confidential and sensitive information safe."
"Defender is a SaaS platform, so it offers more flexibility. Managing the permissions is easier. The solution's automated detection and response features are scalable."
"The basic features are okay and I'm satisfied with the Defender."
"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."
"Overall, I would rate Microsoft Defender for Office 365 at a ten."
"I have a lot of control over spam and phishing emails."
"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."
"Hornetsecurity 365 Total Protection is an easy-to-use solution."
"The most valuable feature is the DMARC Analyzer."
"It's good, it keeps the spam out."
"The platform's most valuable features are journaling and email archiving, effectively stopping phishing attacks."
"Due to our specialized use case, that HIPAA dictionary really comes in handy."
"The piece that is most valuable from the Mimecast standpoint will be the sandboxing feature."
"Mimecast certainly helped my customers reduce phishing emails."
"The product is good. To date, we have not faced any challenges."
"The integration is straightforward."
 

Cons

"There needs to be an improvement in integrating the product to work across multiple operating systems, and to have better support for non-Microsoft file types."
"Configuring the default strategies and policies in Microsoft Defender for Cloud Apps generates a lot of noise and false positives."
"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"Configuration requires going to a lot of places rather than just accessing one tab."
"There is room for improvement in terms of reporting."
"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 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."
"The custom alerts have to improve a lot."
"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."
"A reduction of 10% in pricing can be an improvement."
"The pricing is a little high compared to other products."
"The solution’s pricing is not reasonable."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"The feature that should be included is to remove the block on the encrypted files."
"We have subscribed to an archival service, and yet, when we have to get our data out, we have to pay a fee to get our own data. They charge an extraction fee."
"Their support should be improved. They are notorious for sending you to knowledge-based articles rather than actually talking to you, but that is, unfortunately, kind of becoming a trend with everything. In terms of features, I haven't had any complaints. However, I don't like the fact they moved to a paid training subscription model. They used to have a lot of free webinars for training, but they have started to charge for them in the past year."
"The solution is very expensive."
"While it's quick and easy, the initial setup could be more user-friendly."
"As a user, the user interface of the management console could be upgraded, for example."
"The reaction time between a new threat being identified and Mimecast picking it up needs to be narrowed a bit."
 

Pricing and Cost Advice

"The pricing is normal. Considering its popularity, it's not overpriced."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"Defender for 365 comes in various plans and licenses, along with other Microsoft security solutions. Purchasing this kind of package or security bundle gives good value for money, and that's what I recommend."
"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 product is very expensive."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"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."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"The pricing is acceptable and falls into the medium range, neither cheap nor overly expensive."
"The customers can select the license packages as per their requirements."
"It is a bit expensive."
"The product has good pricing in terms of return on investment."
"We pay monthly fees to our provider."
"It's an expensive solution."
"For what it is, the product is overpriced."
"There are additional costs beyond the standard licensing fee."
"The product price is moderate. I rate the pricing a five out of ten."
