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.

Quotes from Members

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

Pros

"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
"It also gives the vulnerability status according to the versions you have selected. Let's say you have Google Chrome. It mentions the versions it has, and it updates. Within two hours of an update, it is reflected in the dashboard. That's really nice to have."
"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."
"Scalability-wise, I do not think there are any issues so far."
"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."
"Defender is a SaaS platform, so it offers more flexibility. Managing the permissions is easier. The solution's automated detection and response features are scalable."
"Our customers are satisfied with Defender for 365 because Microsoft products are easy to use and customize to meet the client's needs. Everything is in one place, so we can adjust policies as needed for phishing, DLP, ATP, or any other security features that our clients want to apply."
"Does a thorough job of examining email and URLs for malicious content."
"There are many features that are important, but among those, the spam protection feature is very valuable. It help us to safeguard the email against phishing and ensures that there is maximum security enabled for our communication processes. It has a huge role in protecting our emails from potential threats."
"Sophos Email offers encryption and malware protection, provides visibility into emails, has 99% accuracy in catching spam, enhances organizational safety, integrates with various vendors like Microsoft, is deployable with any email service, prevents data loss, features authentication rules, synchronizes with Active Directory and Azure, and includes a self-service portal.

Cons

"The XDR dashboard has room for improvement."
"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 Defender for Office 365 must improve the overall management style, including the GUI. It also needs to change the filters so that it is easy to whitelist and blacklist data."
"Microsoft security solutions work as expected. They are constantly updating the solutions to make them better. At the same time, the changes can impact a customer's environment, and we need to adjust settings. Sometimes we aren't aware of the changes, and nothing is pushed from the backend automatically."
"We noticed that from time to time, Microsoft's stability does have problems. Sometimes the service goes up and down. Sometimes they change without prior notice."
"There is room for improvement in terms of reporting."
"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."
"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."
"Sophos Email can improve security."
"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 main drawback is regarding the technical support."
"The security of the solution could improve."
"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."
"Lacks visibility into spam emails."
"Their technical support is slow to respond."
"There is room for improvement in content filtration, expressions, file sharing, and policy configuration."
"There is room for improvement in content filtration, expressions, file sharing, and policy configuration."
"The solution's pricing could be improved."
"The product's pricing could be more flexible."
