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.

Stable and scalable solution with a great threat isolation engine
Menlo Security RBI is mainly used to do basic cloud migrationary technologies Menlo Security RBI's best feature is its threat isolation engine. Menlo Security RBI could be more cloud-friendly, and its mobility could be improved. In the next release, I'd like Menlo Security RBI to include a…

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

"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."
"I like its investigation capabilities, as that is what is most important to me. It is fairly simple with a user-friendly interface."
"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."
"The basic features are okay and I'm satisfied with the Defender."
"The product's scalability is good."
"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"Microsoft Defender for Office 365 is a stable solution."
"The deployment capability is a great feature."
"I can't say that there is one specific feature that is most valuable. It's the overall platform that is well-suited to our needs. It's something that is different from a lot of other products or platforms in the marketplace."
"Menlo Security RBI's best feature is its threat isolation engine."
"Endpoint and server protection are very effective."
"I rate Sophos Email nine point five."
"I have found Sophos Email to be scalable."
"The anti-malware, risk scanning has been pretty spot on."
"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. The product is very flexible."
"Sophos Email is a stable solution."
"Sophos Email provides both inbound and outbound filtering."
"Our client recently received many emails, and their employees didn't realize these emails were phishing attempts. Consequently, they clicked on them and fell victim to the attack. Therefore, it is important to secure their system with Sophos Email Security."
 

Cons

"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"The product must provide better malware detection."
"Microsoft Defender for Office 365 should be more proactive."
"Configuration at the mid-level could be improved for the support team."
"Microsoft sometimes has downtime, and we'll get several incidents coming in back to back. We have a huge backlog of notifications, many of which may be false positives. However, there might be serious alerts, so we can't risk dismissing all of them at once."
"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."
"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."
"I'd like some additional features any product can give me to protect our environment in a better way."
"Menlo Security RBI could be more cloud-friendly, and its mobility could be improved."
"There are several features, such as supporting web technologies, that the company is working on implementing in the platform. There are a lot of backend web technologies in use on various websites, for example, two-way audio/video and WebGL, for which support may not be fully implemented in the product."
"Sophos Email does not work with split delivery. If I have a domain with 100 mailboxes and want to protect only 50, it is not recommended by Sophos or not possible to configure."
"Sophos Email could improve DLP features."
"The solution should be able to support the cloud environment."
"Enhancing rule creation and customization features would provide users with greater control over their email security settings."
"Email installation could be more user-friendly so that it can be done without involving the partner"
"The tool has some performance issues and bugs, making it an area where improvements are required."
"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."
"Their technical support is slow to respond."
 

Pricing and Cost Advice

"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"The pricing has become expensive."
"Defender for 365 comes in various plans and licenses, along with other Microsoft security solutions. Purchasing this kind of package or security bundle gives good value for money, and that's what I recommend."
"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."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"I know that the product is incredibly expensive."
"The solution could be better by simplifying the business model of their licensing. It was hard to figure out how to get the licensing done for the environment, initially."
"Menlo Security RBI can be very costly."
"The pricing is quite reasonable, with a fixed cost and no additional charges."
"Sophos Email is neither cheap nor expensive."
"The tool's price is reasonable. On a yearly basis, there is a 20 percent increase in prices, but it is not an issue."
"The pricing could improve by having additional discounts. For example, when customers buy have more than 50 or more users, there should be additional discounts."
"We use exchange licenses, for which we get immediate support from Sophos."
"The pricing is affordable, so I’d rate it around a four out of ten on the pricing scale. We pay about fifty pounds a month, including hardware so that costs may differ without it."
"The solution is expensive."
"The tool's pricing is medium."
