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

"It also gives me good visibility because, with Defender, I'm using a Microsoft product to defend Microsoft products. The integration was really seamless and I have wide visibility because it picks up almost everything. Literally, I can see almost every activity that happens, from the e-mail to the workstation itself."
"Microsoft Defender for Office 365's most valuable features are safe attachments and safe links."
"The most valuable aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"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."
"I like its investigation capabilities, as that is what is most important to me. It is fairly simple with a user-friendly interface."
"Since we have started using the solution, there have been fewer compromises."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
"The product is not resource-intensive."
"It has enhanced our approach to tackling malware and spam. It is a reliable product with a good user interface."
"The deployment is very easy. It's quite straightforward."
"The speed and stability were fine."
"The most significant aspect is the response filtering concerning attachments and links."
"The best thing about it is the logs."
"It is a stable solution...It is a scalable solution."
"Endpoint and server protection are very effective."
"The most valuable feature of Sophos Email is the sandbox. We're able to scan the file, isolate it, and look at it before it is delivered. It is highly effective."
"The most valuable feature of Trend Micro Deep Discovery Email Inspector is the simple analysis of phishing emails."
"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."
"Trend Micro is a very good product."
"I find Trend Micro to be a good solution for security purposes."
"The solution's most valuable features include visibility into the network and fast sandboxing technology for alerts, though response time can vary."
"I like that it is very user-friendly and easy to install."
"It can effectively monitor outbound and inbound devices."
 

Cons

"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration."
"There is room for improvement in terms of reporting."
"Configuration at the mid-level could be improved for the support team."
"Configuring the default strategies and policies in Microsoft Defender for Cloud Apps generates a lot of noise and false positives."
"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"Microsoft Defender for Office 365's Mac functionality requires improvement to deliver the same level of protection found on Windows devices."
"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."
"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."
"Sophos Email could improve DLP features."
"The security of the solution could improve."
"Email installation could be more user-friendly so that it can be done without involving the partner."
"The tool's integration becomes an issue when the internet connection is weak."
"The tool's pricing is expensive. In its future release, the tool should make reporting easier to view."
"Sophos Email can improve security."
"Trend Micro's technical support has room for improvement. More efficient support should be provided, especially for standard support."
"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."
"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 product's feature for message processing and blocking devices for bulk emails needs improvement."
"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 Deep Discovery Email Inspector could improve by making it easier to use. Microsoft solutions are easier to use."
"Trend Micro's technical support has room for improvement."
"The dashboard could be improved to match the quality of Check Point Harmony's dashboard."
