Stable, but malware needs improvement and customer support is poor
They need to improve the malware in the product. I am not satisfied with Clearswift because of the lack of customer support. The support is poor, the supplier takes a lot of time and it's expensive. We have some issues here when I contact the supplier, it takes a lot of time for them to get back to us but there's no solution. I am now looking at Symantec as a possible alternative.

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

"A stable solution."
"Ability to create your own content-filtering policies with relative ease."
"The solution ensures that users have not accidentally shared sensitive information with the wrong people or too many people."
"The solution's classification engine is highly configurable and efficient."
"The telemetry to capture everything and the reports are very easy to configure without having a developer degree."
"The analytics would have to be our most valuable feature."
"On the Varonis side, technical support is phenomenal. Their ability to explain is very good, and they seem to be very knowledgeable. When I get an alert that doesn't quite make sense, they dive in there and kind of take me through it. That's very useful and very good. There are some false alerts, but it is better to have a false alert than no alert at all."
"The solution has significantly improved data security and compliance posture by allowing us to track and monitor activities. We can see who accesses data and when files are created and understand what's happening in our environment."
"Technical support from Varonis is rated as nine out of ten."
"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."
 

Cons

"FTP server and TRUST Manager functionality."
"Malware needs improvement."
"The product is very complicated."
"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."
"Varonis requires more access permissions for its core functions compared to competitors, which can be a concern for companies about data safety."
"The solution's areas of improvement are the interface and the dependency on on-premises deployment for some components."
"We have Microsoft Office 365. I just saw an article today which says that they're actually getting integrated with Microsoft Office 365, which would be a useful feature. For user-based reports, log on activity, and stuff like that, it doesn't seem to really be present like Log360. That could just be my inexperience with it. I've been dealing with it for only about two and a half months."
"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

Information not available
"The pricing is good. It neither expensive nor cheap. It is average."
"Licensing is on an annual basis. Maintenance and renewal fees are separate. Varonis Datalert is quite expensive."
"It's expensive, kind of, really expensive."
"I would rate the pricing an eight out of ten, with ten being the most 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 platform is expensive. I rate the pricing a nine out of ten."
"Varonis Platform wasn't certainly the cheapest solution."
