Monitoring has improved data loss detection and now spots abnormal internal file transfers quickly
In my understanding, the best feature Darktrace offers is the identification of copying files, which acts as a DLP, and it is a main concern for companies because users sometimes copy data outside without knowing, especially those without a technical background. When I mention the DLP-like feature and file copying detection, the alerts have been very timely, as we get an alert within a couple of minutes, which is excellent.

The alerts are quite accurate and proactive.

Quotes from Members

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

Pros

"Darktrace is very useful for us because it has a large number of models for detecting threats."
"I have found the most valuable features to be artificial intelligence for cybersecurity, advanced machine learning capabilities, enterprise Immune System, Antigena Network, and Antigena Email. The way the solution detects the threat over the network before it spreads is very good. It notifies you of what the threat is exactly doing and gives you all the details about the execution of that application that had created the threat over your network."
"It is a very simple product to use."
"The most valuable features are the AI and advanced learning tools that distinguish it from other products."
"The most valuable feature is the alerts. The alerts are meaningful. The event rolls up into meaningful and actionable alerts rather than just being noise."
"We're very pleased with Darktrace so it is a bit difficult to pinpoint areas for improvement."
"The solution automatically monitors everything on the network to prevent anti-phishing by monitoring, responding, and restoring the system."
"The support was fantastic, really good."
"It is stable and reliable."
 

Cons

"I think there is some MSSP missing."
"The program is quite expensive."
"There are numerous false positives."
"The solution can improve the reporting. Currently, it only runs weekly and the reporting is complex."
"Upper management wasn't sold on the value proposition."
"The solution's user interface and stability could be improved."
"There is no dedicated salesperson in Egypt, and having one would help to improve focus on this market."
"The pricing is based on the number of endpoints, so the program is rather expensive."
"The solution could be less expensive."
 

Pricing and Cost Advice

"Prior to negotiating, Darktrace offered their appliance and service for $80,000 per year."

"The cost of the solution is expensive for smaller businesses. They will not be able to afford it or might not need this type of security solution."
"The solution is about $6,000 per quarter."
"Darktrace is expensive. You can pay for the license yearly."
"It is expensive. I don't have the price for other competitors."
"The cost of the solution can be reduced to make it more appealing to customers."
