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.
Asif Usmani - PeerSpot reviewer
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.

Quotes from Members

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

Pros

"The stability of Microsoft Defender for Office 365 is fantastic."
"Does a thorough job of examining email and URLs for malicious content."
"The basic features are okay and I'm satisfied with the Defender."
"There are several features that I consider valuable."
"My experience deploying Microsoft Defender for Office 365 was seamless."
"We use Microsoft Defender for its ability to integrate with existing business technologies, which is beneficial for protecting business areas."
"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."
"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 most valuable aspects of this solution are that it protects us from spam and phishing attacks. We had a lot of attacks coming in and then we deployed this solution and they stopped. We no longer have any spam or phishing issues."
"Technical support is great. They are able to look at their patches and offer quick responses. We even have an account manager in the Middle East. They are very good."
"Fortinet FortiMail has a lot of valuable features. It works great. It also has an antivirus feature. Support for Fortinet FortiMail was also great when my team wanted to block some geographic IPs, but couldn't figure out how to do it. The support team provided clear communication on how to resolve that issue. Another valuable feature of Fortinet FortiMail is SPAM filtering which tells you how many spammy emails you've received. Based on my current use cases, I'm happy with Fortinet FortiMail."
"The most valuable feature of the solution is its interface, allowing users to get around the solution easily. The integration capabilities in the solution are also very easy."
"Technical support is great. They're available 24/7 and their response time is typically within the hour."
"Fortinet FortiMail's most valuable features are antispam, antivirus, database, and data loss prevention (DLP)."
"It can block a lot of fake emails."
"The spam filtering is great."
"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."
"Hornetsecurity 365 Total Protection is an easy-to-use solution."
"I have a lot of control over spam and phishing emails."
"Backup and restore are precious features."
 

Cons

"The phishing and spam filters could use some improvement."
"There is a different console for different things; I just want one consolidated console."
"The product must provide better malware detection."
"The GUI is sometimes slow to fetch the device report and could be improved."
"The changes to customer service, specifically the new model for support agreements, are not favorable."
"We need a separate license and we don't know how to get the license that is required."
"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."
"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."
"The main area for improvement is the pricing."
"I need a stable update in the product that stays for a long time instead of having to deal with frequent updates."
"The infrastructure could be improved."
"There are features that other solutions have that this one is lacking, such as reporting options. I hope in future releases they advance their features list."
"FortiMail's dashboard is somewhat complex and could be made simpler."
"I think they need to look into it and improve their signatures. This will help with blocking incoming spam emails."
"The solution's pricing could be improved."
"It can be easier to configure or connect to the cloud to report on the attachments."
"The solution’s pricing is not reasonable."
"A reduction of 10% in pricing can be an improvement."
"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."
