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.

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 a powerful and simple email protection with proven management benefits
Sophos Email is integrated with Office 365 and Google Workspace. It offers anti-spam functionality, which is easy to manage and comes with documentation on how to integrate it with Office 365 and Google Workspace. It provides a defense layer for email protection, scanning every incoming and outbound email for malware and spam. It can also function temporarily as an email solution if my vendor from Office 365 or Google Workspace is out of service.

Quotes from Members

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

Pros

"The most valuable feature of Microsoft Defender for Office 365 is data backups that we can provide through ticket requests."
"My experience with customer support and technical support for Microsoft Defender for Office 365 has been excellent."
"It gives us visibility into threats and, for endpoints, it helps us to prioritize threats. We used to have a lack of visibility, but now our time to detect and respond has decreased."
"Microsoft Defender for Office 365 has improved my organization's security. It makes it easier to manage the infrastructure without the help of third-party applications."
"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 DLP feature of Microsoft Defender for Office 365 is valuable, and we also use the DLP feature for email real-time detection."
"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 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."
"Cloudflare Access is part of the Zero Trust philosophy."
"Cloudflare, in my opinion, was easy to implement."
"Cloudflare is simple to use."
"The simplicity of the solution is its valuable features as almost no effort was needed to learn the configurations. It is also one of the cheapest firewalls available in this category."
"It will take the blow rather than our applications should an attack occur."
"Cloudflare is by far the most effective solution that I have come across."
"Enables me to work from two locations."
"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."
"The most valuable feature is its email security."
"It's easy to use and the configuration is straightforward."
"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."
"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 best thing about it is the logs."
"The solution protects users from phishing links and spam."
"The feature of Sophos Email that we find most effective for detecting suspicious emails is primarily based on their signatures."
"The tool's most valuable feature is the anti-spam detection filter. Its threat email intelligence features help to identify email data."
 

Cons

"The UI needs to be more user-friendly."
"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."
"Specifically, within Microsoft Defender for Office 365, I want it to improve the DLP capabilities."
"Specifically, within Microsoft Defender for Office 365, I want it to improve the DLP capabilities."
"The GUI is sometimes slow to fetch the device report and could be improved."
"Configuration requires going to a lot of places rather than just accessing one tab."
"The custom alerts have to improve a lot."
"They have moved features from one console to another. Things have been moved around in the interface and it takes me time to find where certain features are."
"The initial onboarding was causing us some confusion."
"Operating and tuning the product is difficult."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"Our subscription plan for the solution has a limitation of bot signatures."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"Cloudflare DDoS has poor technical support."
"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."
"There are premium tier live service and lower tier live service, so we opted for the lower tier. But there is no medium tier where we pay a little extra and get a bit more service. So if that can be improved."
"Sophos Email could better detect fake emails, especially when the domain names are similar. It needs to improve spotting spoofed domains, like when one letter differs in a domain name. It also needs to incorporate AI detection. Barracuda detects suspicious emails better. However, malware scanning is better in Sophos Email."
"The security of the solution could improve."
"The main drawback is regarding the technical support."
"The tool has some performance issues and bugs, making it an area where improvements are required."
"Sophos Email could improve DLP features."
"Sophos Email can improve mail security."
"The tool's integration becomes an issue when the internet connection is weak."
"Email installation could be more user-friendly so that it can be done without involving the partner."

"The product is very expensive."

"Most of our clients are on a perpetual license. If there is a budget issue, they can choose a subscription. However, most of the clients choose the perpetual license."
