Offers the ability to identify sensitive areas, allowing you to drill down into the sensitive data
The most effective feature for me is its ability to identify sensitive areas, allowing you to drill down into the sensitive data, provided you have access, to determine whether it's a false positive or a true positive. That's the best thing for me, out of all of it. It's got everything, like other ones, but I like to be able to look at something if I'm doing forensics on the alert and say, "Okay, do I really need to do something with this?" For example, we don't want sensitive data in our OneDrive. So it identifies the sensitive data that's possibly in the OneDrive. And what I can do is look at it and identify whether it's actually sensitive data in Datalert or whether it looks like sensitive data, but I know it's a false positive. If it is a false positive, I can basically say ignore this pattern based on X, Y, and Z, you know, whether it's Redjax or keyword proximity. So I like that. With other tools, I gotta go through a whole process because it's a little bit more complex. Here, I can tag it and bag it in one shot. And the next good time I scan, it slips over it. So it helps in that.

Quotes from Members

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

Pros

"Secure Email Threat Defense's scalability is good."
"The ability to see east-west traffic is its most valuable feature. Traditionally, email defense focuses on north-south, inbound-outbound, egress-ingress traffic. With Cisco Secure Email Cloud Mailbox, it's able to quickly identify, track, tag, and categorize emails that are internal. That can typically give us visibility into if there's an internal compromised account (for example). Someone can then use that internal compromised account to email additional accounts with either malicious software or links, but internal within that Office tenant. Effectively, that email message never leaves the tenant. Any of the mail gateways really do not have any method or way of seeing this traffic since it's not leaving the environment."
"Regarding stability, Cisco Secure Email Threat Defense is very stable."
"Cisco Secure Email Cloud Mailbox can handle a complete portfolio, which is required to protect any kind of attack coming from emails. However, it does not have advanced phishing, but it is available through Cisco. If you compare Cisco Secure Email Cloud Mailbox with the competition, in the competition you have to have one or two solutions together to address the customer's requirement, whereas Cisco Secure Email Cloud Mailbox is addressing everything, such as web domain and email protection. If there is any kind of challenge it will come across through email."
"The features and functionalities are much better than Microsoft's in-built Defender plan."
"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."
"On ease of use, it rates very high. It's something that I was able to get into without really looking at any documentation. I wanted to see what it felt like before I started looking at any documentation on how to use it, and it was very easy to use. It works very smoothly. The user experience is very intuitive. They did an amazing job on that."
"The advanced threat analytics and URL filtering in threat detection are good features that are working well."
"It can easily identify unusual behavior or access patterns that may pose a potential threat, while operating as a unified reporting system."
"The telemetry to capture everything and the reports are very easy to configure without having a developer degree."
"The solution's classification engine is highly configurable and efficient."
"Varonis Platform is transparent and captures everything in the environment without impacting the performance. The tool helps us unify data feeds into a single reporting system."
"The solution ensures that users have not accidentally shared sensitive information with the wrong people or too many people."
"I also appreciate the reporting feature, which allows for the extraction of various reports based on specific needs. These reports can be used for audit purposes, such as tracking changes in file locations or deletions."
"The most important feature is remediation. In remediation support, there is no group permission. We'll go ahead and remediate the access from the Dell folder to the parent folder."
"The analytics would have to be our most valuable feature."
 

Cons

"The learning curve shows that in the beginning, there are numerous false positives. For one month, we had to reclassify the false positives manually until the system learned."
"Cisco Secure Email Cloud Mailbox can improve by adding advanced phishing, then the solution would become the best in the market. However, this could increase the price even more. Additionally, if CES with domain protection could be added it would be an even better solution."
"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
"Customers will benefit greatly from monthly billing because the majority of customers today use the cloud, be it Office 365, or Google Cloud."
"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"The product's complexity at times results in redundant rule sets that are difficult to untangle, highlighting the need for streamlined management systems and a more user-centric approach to system configuration."
"The solution is a bit expensive."
"This solution could be improved by integration with Sandbox."
"It is significantly complex."
"There is one thing that if I add something manually, I get so many alerts. That's the biggest bad thing."
"The solution's areas of improvement are the interface and the dependency on on-premises deployment for some components."
"The GUI should be more functional. There should be a process for connecting through Chrome, Internet Explorer, etc."
"I'd like to see automatic updates for this solution. Currently, it's a manual process to update all the keywords"
"Varonis requires more access permissions for its core functions compared to competitors, which can be a concern for companies about data safety."
"The remediation process can be improved. There will be no existing permission group for the McAfee channel domains. We can create a new permissions group for the required folder."
"One area for improvement is the calculation engine. When applying rules in Varonis, especially for large datasets (terabytes of data), the calculations can be slow and require time to process. Speeding up this process would be beneficial."
 

Pricing and Cost Advice

"Cisco Secure Email Cloud Mailbox does not have any competition with Sophos, Trend Micro, or other vendors of the world. However, there is a pricing premium for the solution. One has to look at it from that angle that while they are buying Cisco, there will be a premium, and Cisco justifies that premium value. That's why they're charging a high price."
"It is expensive compared to other vendors."
"The solution’s pricing is manageable."
"The feedback from vendors and customer is that it is expensive."
"I would rate the pricing an eight out of ten, with ten being the most expensive."
"Varonis Platform wasn't certainly the cheapest solution."
"It's expensive, kind of, really expensive."
"Licensing is on an annual basis. Maintenance and renewal fees are separate. Varonis Datalert is quite expensive."
"You could do a subscription, where you pay yearly, or you could purchase it outright. The licensing cost is based on the number of users on the system that you are monitoring."
"The pricing is good. It neither expensive nor cheap. It is average."
"The platform is expensive. I rate the pricing a nine out of ten."
