Featured Reviews

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.
Nigus Machin Amare - PeerSpot reviewer
Offers advanced protection from email-based attacks and consistently blocks spam
The most valuable features are Fortinet FortiMail ( /products/fortinet-fortimail-reviews )'s ability to protect from advanced features of email-based attacks, including protection against ransomware and malware attacks. It is especially effective in blocking spam through standards like wrong source IP for email-based attacks. Its high scalability and stability, especially for financial institutions, are noteworthy.
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

"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."
"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."
"The basic features are okay and I'm satisfied with the Defender."
"Microsoft Defender for Office 365 is a stable solution."
"The email protection is excellent, especially in terms of anti-phishing policies."
"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."
"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 deployment capability is a great feature."

Cons

"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."
"Configuring the default strategies and policies in Microsoft Defender for Cloud Apps generates a lot of noise and false positives."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"The GUI is sometimes slow to fetch the device report and could be improved."
"Microsoft Defender for Office 365 could improve by giving customers information on techniques to prevent threats. For example, information about best practices on how to protect their own devices against hackers and scammers, such as educational information or training. This would help others have a better understanding of cyber security. Additionally, there can be more security features added."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"You should be able to deploy Defender for every subscription without the need to add servers."
"Fortinet FortiMail's pricing could be improved."
"The only drawback to this solution is that the firmware is frequently updated, and each update results in downtime."
"ortiMail has some latency issues and sometimes takes time to receive emails."
"The web console management interface could be improved."
"They should add a lot of threat-intelligence feeds from different sources - not only from one source (FortiGuard)."
"The statistics and BI in general could be improved."
"High Availability needs improvement."
"It would be nice if we could manage the solution from the cloud so I could handle things off-site if necessary."
"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."
