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.

Provides good identity proxy features, but sandboxing and spam control features could be improved
Sophos gives you a feature set to manage your on-premises firewall on the cloud. I just integrated my on-premises firewall into the cloud, and I can manage the tool through the cloud as well if needed. I recommend using Sophos Email as a proxy. For email gateways, I advise choosing mature products with rich feature sets, like Trend Micro or CrowdStrike. The solution's integration with other tools is very simple. I easily integrated Sophos Email with my Active Directory. My organization needs a WAF with a limited feature set, which we use through Sophos. Purchasing additional WAF will be costly, but I get sandboxing and WAF features free of cost with Sophos, which is included in the license. Overall, I rate the solution a seven out of ten.

Delivers strong security with potential for improved support efficiency
I sell solutions for security support. We offer an email gateway and serve bank clients I find Trend Micro to be a good solution for security purposes. In comparison to other software, SoftForce offers a very good solution. Trend Micro's technical support has room for improvement. More efficient…

Quotes from Members

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

Pros

"The benefit that stands out to me is the ability for multiple individuals to collaborate simultaneously within the same document. Additionally, there is the option to save the document directly in the integrated OneDrive or SharePoint."
"The solution is very easy to use. All you have to do is to assign the license to the end-user and it's done. The customer will only have the feature activated, and the solution will monitor the emails to determine if they are a threat or not."
"The technical support is good and quick to resolve issues."
"The stability of Microsoft Defender for Office 365 is fantastic."
"The email protection is excellent, especially in terms of anti-phishing policies."
"The basic features are okay and I'm satisfied with the Defender."
"The initial setup is straightforward. You just add the license, click it, and then you can set up the rules. It is quite simple."
"The good part is that you don't have to configure it, which is very convenient."
"It has enhanced our approach to tackling malware and spam. It is a reliable product with a good user interface."
"The platform is scalable when installed on server-based systems."
"The best thing about it is the logs."
"I cannot guarantee any email by its name. It can be spam. Sophos Email helps to double-check whether an email is spam or not. It has a dashboard which gives an overview of the alerts."
"The anti-spam functionality of Sophos Email is good."
"Good VIP protection, time of click protection and the Sandstorm feature."
"The most significant aspect is the response filtering concerning attachments and links."
"Sophos Email is a stable solution."
"I like that it is very user-friendly and easy to install."
"The solution's most valuable features include visibility into the network and fast sandboxing technology for alerts, though response time can vary."
"It can effectively monitor outbound and inbound devices."
"I would rate the solution's stability at ten out of ten."
"I highly recommend Trend Micro Deep Discovery Email Inspector due to its security and scalability features."
"I find Trend Micro to be a good solution for security purposes."
"The most valuable feature of Trend Micro Deep Discovery Email Inspector is the simple analysis of phishing emails."
"Trend Micro is a very good product."
 

Cons

"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"The custom alerts have to improve a lot."
"Several simulation options are available within 365, and the phishing simulation could be better."
"The certification training for Defender for 365 needs to be deeper and incorporate Sentinel. I took all the security courses except one, and Sentinel isn't included."
"Microsoft sometimes has downtime, and we'll get several incidents coming in back to back. We have a huge backlog of notifications, many of which may be false positives. However, there might be serious alerts, so we can't risk dismissing all of them at once."
"The changes to customer service, specifically the new model for support agreements, are not favorable."
"About eight months ago, we started to measure the quantity of phishing and spam that we have been receiving, and it has been increasing a lot. That means that protection for our email is not as good as we were expecting."
"The security of the solution could improve."
"Lacks visibility into spam emails."
"The solution should be able to support the cloud environment."
"There have been some issues with compatibility and effectiveness, particularly when integrating it with our firewall. The main challenge has been email protection, especially due to compatibility issues and difficulties with log access and email relay configuration."
"The tool's integration becomes an issue when the internet connection is weak."
"Enhancing rule creation and customization features would provide users with greater control over their email security settings."
"However, the setup was tricky, particularly with the DNS routing between Microsoft Exchange Online and Sophos cloud services. It took me about four attempts to get it working correctly. Despite that, Sophos Email does everything we need, so we don't require any additional capabilities now."
"The tool’s stability should be improved."
"The product's feature for message processing and blocking devices for bulk emails needs improvement."
"Trend Micro's technical support has room for improvement."
"The tool needs to incorporate faster response times for issue detection, more detailed reports, and better compatibility with older operating systems (e.g., Windows 7, 8, Server 2012)."
"The dashboard could be improved to match the quality of Check Point Harmony's dashboard."
"I would like to be able to send emails to a specific sandbox. This is a feature I would like to see added to the next release."
"Trend Micro's technical support has room for improvement. More efficient support should be provided, especially for standard support."
"Trend Micro Deep Discovery Email Inspector could improve by making it easier to use. Microsoft solutions are easier to use."
"It could be more user-friendly, easier to install, and lighter on the network. I would say that for all products because you do not need technical expertise to take care of it. When you have a user-friendly solution, it makes it easier for the vendors or companies like us. We do not have to go to the client's site to attend to issues all the time. Because it is user-friendly, they can take care of it after some training."
