We performed a comparison between Microsoft Defender for Office 365 and Sophos Email based on real PeerSpot user reviews.Find out in this report how the two Email Security solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI.
"There is a huge return compared to if we didn't have a gateway appliance, as far as blocking malicious emails."
"The solution is very configurable. It has enabled us to configure some specific filters to stop emails that general configurations didn't stop. It's a powerful solution. It can analyze a lot of emails simultaneously, with no problems of capacity or system load."
"The filtering is definitely better at catching both spam and malicious messages, and there's a lot of extremely granular ability for setting up rules. You can do it the way you want to. The Microsoft solution tends to be pretty limited in how it allows some of that to be done."
"Cisco Secure Email Cloud Gateway has allowed our users to be able to concentrate on the emails that they do receive. Previously, our users had to deal with nine million additional emails across the organization, which is nearly 1,000 emails per user to have to deal with a month. That's a massive amount for our staff to deal with and probably several hours of their time. We have a lot of clinical staff, being a hospital. We want to make our staff as productive as possible. By removing a lot of that spam and phishing type emails, this allows them to do their job."
"The malicious URL scanning, as well as the anti-malware features, have been really useful for us in our environment."
"Anti-Spam and Advanced Malware Protection are the most valuable features... and we also have the option to block Zero-day attacks."
"The added value of it is that every migration to a new version is initiated by the Cisco version itself, so that is a bunch of work that you don't have to do on the Cisco ESA system on-premise. As it becomes a safe platform, you don't need to invest anything in your own data center or in your upgrade path."
"I love the Advanced Malware Protection feature. It works very well... The appliance has more security such as SDF, DKIM, DMARC, and encryption."
"The most valuable feature is the integration. It's a single console, so we don't have to switch around between multiple products. Another valuable feature is the ease of operations and maintenance."
"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"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."
"Threat Explorer is one of the features that I very much like because it is a real-time report that allows you to identify, analyze, and trace security attacks."
"The risk level notifications are most valuable. We get to know what kind of intrusion or attack is there, and we can fix a problem on time."
"Does a thorough job of examining email and URLs for malicious content."
"At the moment we are satisfied with this product. It's a stable, scalable, and resilient solution for us."
"The good part is that you don't have to configure it, which is very convenient."
"I have found Sophos Email to be scalable."
"Sophos Email is a stable solution."
"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."
"It's easy to use and the configuration is straightforward."
"When you say email security, it's about everything, incoming email, outgoing email, spam, phishing emails, unwanted marketing emails. You can set rules, but the main feature of Sophos Email is to make sure you don't get hacked. 95% of people who are hacked do not get hacked by typing the router password. They are hacked from the inside out, which means they send you a document that is a zero-day attack, you open it, nothing happens, but technically the attack is running in the background of your computer. This is how they gain access to your PC."
"The speed and stability were fine."
"The interface is dated. It has looked pretty much the same for 15 years or so. It would be helpful to be able to do everything from one spot. The centralized quarantine and reporting are completely separate from policy administration."
"I use the search all the time. Sometimes, it is hard to search for things and things are hard to find. People come to me all the time, saying, "This email didn't get through." Then, I go searching and don't find it on the first search. You have to think about alternative searches. I don't know if there is an easier way that they could help to find things. I don't know how they could simplify it, because now everybody else is using the cloud and everything is coming from Office 365, or whatever. It is just not the same environment from years ago where everybody had their own server and you could search easier."
"We have been struggling in the last month with Cisco encryption and with the S/MIME encryption. I don't know if it is an issue on our side or if these features of the solution are not working very well."
"I would like more functionality and how to use it for Level 2 type staff. The biggest issue is it needs to be easier to use and navigate."
"The Forged Email Detection feature needs improvement, particularly with domain. The sensors are not that good and the rules sets are unclear."
"We have Microsoft and we have the E5 licenses, they have more EDR responses on certain emails. That's something that Cisco ESA on the cloud doesn't have. They don't do anything about MITRE attacks. They only detect if there is a malicious email or a threat and they remove it."
"The configuration UI should be made more intuitive. Currently, it takes a while to understand how to do the basic configurations."
"The UI is definitely one area of improvement because it doesn't match other interfaces and the navigation can be a little clunky."
"We need a separate license and we don't know how to get the license that is required."
"Too many false positives and lacks an accurate capability to detect malicious SharePoint sites."
"I'd like some additional features any product can give me to protect our environment in a better way."
"They can improve their security in a way where a customer can know if all their attachments are safe or not to open through a report. The solution does its job perfectly, but it never reports to the customer whether those attachments have been stopped before or not."
"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."
"It would be better if it were more scalable. It depends on the architecture, but we would like to make it more scalable for both data centers."
"The visibility for the weaknesses in the system and unauthorized access can be improved."
"Sophos Email can improve mail security."
"The security of the solution could improve."
"The solution should be able to support the cloud environment."
"Sophos Email can improve security."
"The installation of Sophos Email could be easier. It's a bit difficult because setting up the email virtually requires some bit of technical knowledge."
