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.

Helps prevent security breaches but fails to improve in the area of AI
I have not noticed any impressive advanced threat protection mechanisms in the tool. I don't know if there are any AI features in the product. I don't know if there is any other technology embedded in the solution. Cisco Secure Email successfully mitigated potential email threats. My company has seen plenty of scenarios where Cisco Secure Email successfully mitigated potential email threats, spam emails, and fraudulent domains. The product is good for dealing with spam emails, and it can take care of more than 100 spam emails per day. A huge number of spam emails are monitored with the help of Cisco Secure Email. I would not recommend the product to other businesses because you need to have some kind of expertise in configuring and knowing a bit about the tool's GUI. The tool also lacks in the area of AI mechanics. If I would like to have an overview and review another solution, I would go for another product other than Cisco Secure Email. I can definitely suggest others to look at the product and review it, but I would also recommend that they compare it with the other solutions in the market. I wouldn't prioritize Cisco Secure Email over other tools. Either the support partner of the product or I take care of the tool's maintenance phase by looking into the configurations and doing some fine-tuning. I rate the tool a seven to eight out of ten.

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…

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 is protection against malicious links, fishing, and impersonation. You can train people to be aware of these threats, but they're not always careful. When they're using their phones between meetings, they click on a link, and it's game over."
"Microsoft Defender for Office 365 facilitates efficient management and updates through the cloud. We do not have to worry about incompatibilities. It just works."
"The good part is that you don't have to configure it, which is very convenient."
"The product's scalability is good."
"Defender helps us prioritize threats across our organization."
"The most valuable aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"At the moment we are satisfied with this product. It's a stable, scalable, and resilient solution for us."
"It’s easy to handle integrations, and we don't need a lot of people in our IT team."
"My favorite feature of Cisco Secure Email is the threat intelligence capabilities, particularly its integration with Cisco Talos."
"Cisco's Secure Email integrates with Cisco Firewalls, utilizing the AMP as their anti-malware engine, which allows for information sharing between devices."
"It is doing its work. It is doing what it was actually designed to do. It has ensured we don't have business email compromises, and it has also ensured that our brand Galaxy is unique all year round."
"This solution provides some benefits, like comfortable access to TAC support. You get prompt support when working directly with Cisco."
"The technical support from Cisco is perfect."
"The tool comes with AI features. It is good for clients who already use Cisco products due to integration."
"I love the Advanced Malware Protection feature. It works very well... The appliance has more security such as SDF, DKIM, DMARC, and encryption."
"It sends us reports, where we can see if there have been attacks, e.g. DDoS. If so, we can switch to a clean IP."
"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."
 

Cons

"The phishing and spam filters could use some improvement."
"Configuration requires going to a lot of places rather than just accessing one tab."
"There is a different console for different things; I just want one consolidated console."
"The XDR dashboard has room for improvement."
"We still see many false positives from time to time with Microsoft Defender for Office 365, so it would be good if we can reduce those false positives and provide better workflows for our end users, as sometimes they may not know what to do when they encounter a false positive."
"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 custom alerts have to improve a lot."
"The visibility into threats is not up to the mark, as I do not have control. I rate my experience with Microsoft Defender for Office 365 as six out of ten due to troubleshooting and pricing concerns."
"We cannot manage multiple devices from a single UI."
"The solution does not have a strong outbound service. It should also integrate DLP."
"In some cases, detection is missed, leading to false positives where genuine emails are flagged as spam."
"The user interface is a bit complex."
"The graphical user interface is not user-friendly like other vendors. I find it very difficult at times to find some options on the UI."
"While Cisco offers excellent solutions and innovations, the pricing may not be suitable for everyone. The cost of the software is relatively high. In the current market, there are numerous competitive alternatives that focus on security, enterprise networks, and various other aspects. Cisco, being a comprehensive provider, extends its expertise across data, servers, storage, and security, making them a preferred choice for many enterprises. However, when it comes specifically to security solutions, there are other vendors that specialize solely in this domain, offering competitive options."
"The product's GUI for the dashboard needs improvement."
"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."
"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."
