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.

The solution enables seamless security management and fosters a learning environment
Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions. For the solution stopping us for e-learning, I appreciate the concept yet need more resources or courses in Mexico, preferably in Spanish. Certifications are easy, however, I require more real-world environments and instructors.

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

"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."
"The basic features are okay and I'm satisfied with the Defender."
"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."
"The stability of Microsoft Defender for Office 365 is fantastic."
"It’s easy to handle integrations, and we don't need a lot of people in our IT team."
"Microsoft Defender for Office 365 helps people to work remotely. It is a secure solution. We don't need to use our company's computers or get VPN connections to the networks. I can control how they share screens and what they send to the devices. It keeps our organizations confidential and sensitive information safe."
"Microsoft Defender for Office 365's most valuable features are safe attachments and safe links."
"At the moment we are satisfied with this product. It's a stable, scalable, and resilient solution for us."
"The best feature is rate limiting. If I'm expecting 500 visits per hour, Cloudflare will limit the requests if I suddenly get 50,000."
"I'm very satisfied with the environment and the dashboard."
"The capabilities of the software are strong enough for me to do what it's supposed to do. For me, we don't need to do a lot of configuration on our site. We just enable it and monitor it."
"Clover is the best product globally."
"Cloudflare, in my opinion, was easy to implement."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"The solution has different options that can be used to differentiate DDoS attacks."
"Enables me to work from two locations."
"The feature of Sophos Email that we find most effective for detecting suspicious emails is primarily based on their signatures."
"The most significant aspect is the response filtering concerning attachments and links."
"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 solution's identity proxy feature is very good and reliable."
"Endpoint and server protection are very effective."
"The platform is scalable when installed on server-based systems."
"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."
"Sophos Email is a stable solution."
 

Cons

"In one of the reports I can get the exact place where a vulnerable file resides. But for that, I need to explicitly go into the device and check. If they could include that file part in the report, without my having to go to the device itself, that would help."
"We are always looking for others tools to increase automation on tasks. There can be better integration with other solutions, such as PowerPoint and email."
"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."
"The pre-sales cost calculations could be more transparent."
"Configuration requires going to a lot of places rather than just accessing one tab."
"The changes to customer service, specifically the new model for support agreements, are not favorable."
"One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration."
"I'd like some additional features any product can give me to protect our environment in a better way."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"The response time for support must be reduced."
"Lacks a VPN feature to provide a secure connection to the data center."
"The onboarding process can be improved a little bit."
"When there are any dynamic changes in complex applications, the tool takes a lot of time, making its analytics-related area a major matter of concern where improvements are needed."
"The initial onboarding was causing us some confusion."
"Operating and tuning the product is difficult."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"The solution has not found a way to block certain kinds of phishing emails."
"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."
"Email installation could be more user-friendly so that it can be done without involving the partner"
"It was sometimes hard to find the settings in the solution's interface."
"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."
"Servicing and support are areas with shortcomings where the solution needs to improve."
"The security of the solution could improve."
"The tool's integration becomes an issue when the internet connection is weak."
 

Pricing and Cost Advice

"The pricing has become expensive."
"I know that the product is incredibly expensive."
"For licensing, it's usually a yearly package for customers who are subscribed to Office 365, but they can also pay on a monthly basis."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."

"The pricing of the solution is cheap. The licensing cost is also very low. I rate the cost and pricing a three out of ten."

"It falls somewhere in the middle—it's not excessively expensive nor very cheap."
