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.

Lags in terms of grabbing phishing emails or phishing campaigns, though it has good scalability
Armorblox is a cloud-based solution. The solution helped us improve the security, but we had a couple of issues regarding the operation. From an email security perspective, users or employees don't need gray mail or phishing emails in their email boxes. So, if the tool is not performing well in that area, then there's no sense in using that particular tool. Overall, I rate Armorblox a five out of ten.

Cons

"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"The pre-sales cost calculations could be more transparent."
"The UI needs to be more user-friendly."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"The visibility into threats is not up to the mark, as I do not have control. I rate my experience with Microsoft Defender for Office 365 as six out of ten due to troubleshooting and pricing concerns."
"Configuration at the mid-level could be improved for the support team."
"Microsoft security solutions work as expected. They are constantly updating the solutions to make them better. At the same time, the changes can impact a customer's environment, and we need to adjust settings. Sometimes we aren't aware of the changes, and nothing is pushed from the backend automatically."
"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."
"Armorblox lagged in terms of grabbing phishing emails or phishing campaigns."
"The support team was a bit slow."
"The solution could lower its price."
"The email DLP portion could be a bit easier."
"The high cost of the product is an area of concern where improvements are required."
"Sometimes it doesn't detect actual spam emails, and sometimes it catches normal emails."
"It's scalable, but the devil's in the details — you have to know your email volumes."
"Integration and filtering out who you want and don't want to have integrated ID could be improved."
"Sometimes it detects false positives."
 

Pricing and Cost Advice

"The product is expensive."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"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."
"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing a five out of ten."
"The licensing is basically $8/user."
"We sell annual licenses for this solution."
"Proofpoint Email Protection has comparable pricing."
"Annually, it costs us about $92,000. This is pretty much what it costs us. There is no additional cost."
"The price is reasonable."
"Proofpoint is fairly expensive."
"It is on a yearly basis. Their floor for SMB doesn't matter. The user count is 100 users and below at $2,500 a year. Its cost is higher than other solutions. It is probably about 20% to 30% higher than what you would get with Microsoft. There are no additional costs. All costs are factored in. It can be improved pricing-wise so that it is affordable for the SMB market."
"The solution charges per user per month to use it. There are not any additional fees in addition to the standard living fees."
