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.

Secure email management improves through advanced filtering and dynamic virus scanning
Fortinet FortiMail offers capabilities like settings for mail delivery, mail filtering, spam controls, and email bursting prevention. It also allows for email forwarding, dynamic filtering, and scanning based on virus signatures. I can set varying levels of security. The tool is flexible and provides essential features for mail security and management.
Bruno Rolland - PeerSpot reviewer
A stable tool capable of detecting malware while focusing on anti-phishing to protect its users
I don't see ISO 27001 in the solution. While working on the solution, sometimes a customer needs to have a conformity level of SOC 1 or SOC 2 or some other conformity level. I did not see the aforementioned conformity levels added to the solution. Concerning a bank, data can be confidential, and when a bank needs to transfer such data, it has to be specific to a certain level of conformity, which I did not see in the product. Vade needs to incorporate the aforementioned aspects to improve their solution.

Quotes from Members

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

Pros

"We use Microsoft Defender for its ability to integrate with existing business technologies, which is beneficial for protecting business areas."
"It gives us visibility into threats and, for endpoints, it helps us to prioritize threats. We used to have a lack of visibility, but now our time to detect and respond has decreased."
"The product's scalability is good."
"The risk level notifications are most valuable. We get to know what kind of intrusion or attack is there, and we can fix a problem on time."
"The DLP feature of Microsoft Defender for Office 365 is valuable, and we also use the DLP feature for email real-time detection."
"My experience with customer support and technical support for Microsoft Defender for Office 365 has been excellent."
"Defender for 365 is a comprehensive cloud-based solution. The value of the cloud is that you aren't alone. Threat intelligence and analytics are shared in the cloud. We don't have to find the solution alone. If you face an unknown threat with traditional solutions like Trend Micro and Symantec, you need to open a case and send your information to them to analyze forensically and identify the source of the attack."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
"The solution is very, very stable."
"The most valuable feature of Fortinet FortiMail is its fully detailed dashboard."
"I like the anti-spam and security features of Fortinet FortiMail, and that its features complement each other."
"It is a scalable solution."
"It actually filters the compromised emails when on a network layer itself."
"FortiMail effectively filters all emails coming to our mail server, blocking malicious ones automatically."
"Fortinet FortiMail is easy to use and the detection rate is very good. You can customize content filters and profiles are done easily. Additionally, there is a sandbox integration feature that is good."
"The user quarantine feature in the solution is good...It is a stable solution."
"It is a stable solution...My company has no worries about the deployment phase of Vade for Office 365."
 

Cons

"Too many false positives and lacks an accurate capability to detect malicious SharePoint sites."
"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 phishing and spam filters could use some improvement."
"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."
"Microsoft Defender for Office 365's Mac functionality requires improvement to deliver the same level of protection found on Windows devices."
"Configuration at the mid-level could be improved for the support team."
"Specifically, within Microsoft Defender for Office 365, I want it to improve the DLP capabilities."
"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 should add a lot of threat-intelligence feeds from different sources - not only from one source (FortiGuard)."
"What's missing in Fortinet FortiMail is some sandbox information for some of the emails. It's probably configuration-based, where it could be configured on some emails. For example, there was malware in some emails that weren't detected in some of the Fortinet FortiMail sessions, but it should have been configured from my company's end to better catch scam emails, but overall, the solution is okay. At the moment, my company is okay with the current Fortinet FortiMail offerings, but in the past, because of a lack of understanding, my team wasn't able to quickly implement the geographical IP blocking feature. It was time-consuming to implement that feature, but that wasn't a fault of Fortinet FortiMail. The issue was from my team's end, but just by emailing the support team, that issue was resolved, so right now, there isn't any additional feature I'd like added to Fortinet FortiMail."
"The support could be faster because we've been receiving complaints from customers, they say that when they raise a ticket, it doesn't take 24 hours to respond, sometimes the support responds after three days. This is a lot of time."
"I don't know if it is possible, but I would like to see Artificial Intelligence and machine learning introduced."
"I believe there is room for enhancement in content and web security features."
"The solution could be improved by providing a virtual machine facility with a complete set of options in the VM setup."
"A room for improvement in Fortinet FortiMail is that it only has a hardware version. I also didn't find the solution scalable, so that's another area for improvement."
"High Availability needs improvement."
"Concerning a bank, data can be confidential, and when a bank needs to transfer such data, it has to be specific to a certain level of conformity, which I did not see in the product."
 

Pricing and Cost Advice

"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"I know that the product is incredibly expensive."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"The pricing is normal. Considering its popularity, it's not overpriced."
"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."
"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 is reasonably priced compared to one of its competitors."
