Pasan Jayarathna - PeerSpot reviewer
Network Security Engineer at Cyberwell Solution
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. Even if some developers are working after hours and copying files, our SOC team detects this, and most of the time they call us so we can identify the users. 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

"I like the Antigena feature in Darktrace, as it offers immediate response and is helpful."
"This is something that is really easy to implement in an organization, gives us good visibility about what is happening in our networks and on the system, and we like the transparency available within our infrastructure now."
"I particularly like Antigena and the analytics around the real-time monitoring of our network."
"We're very pleased with Darktrace so it is a bit difficult to pinpoint areas for improvement."
"It provides a comprehensive cybersecurity solution that monitors my cloud accounts as well as my local network."
"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."
"I have used multiple solutions, but its graphical user interface is quite interesting and quite descriptive. There are a lot of video animations, and we can easily see how the data is transferred between various points. That's something really interesting. It is also quite easy to understand for a new user."
"The Enterprise Immune System, Cyber Artificial Intelligence Analyst, and Antigena technology are all very useful aspects of the product."
"It is stable and reliable."
 

Cons

"The Darktrace Mobile app needs improvement as it's currently limited in functionality, and the learning AI takes a while to adapt to new devices, flagging new users as threats for up to a month before recognizing them as regular network users."
"I am not so satisfied with the pricing model for Darktrace. The price is a little bit high compared to other solutions."
"We'd like threat hunting, and we'd like to see a global solution that can automate vulnerability scans. I know it is something they are working on."
"Darktrace needs to automate the reports of false positives, botnets and everything."
"I feel that Darktrace could be improved, particularly in the support aspect which is currently very poor. We need to chase Darktrace instead of them being proactive with us."
"With Darktrace, at the moment, I have to almost put in a date and tell them that I want you to give me data from this date to this date."
"The main portal needs improvement as it is difficult to use."
"My only criticism of the product is that its licensing model isn't flexible."
"The solution could be less expensive."
 

Pricing and Cost Advice

"It is a very expensive product."
"Our customers feel that the price of Darktrace is quite high compared to other solutions."
"The cost is moderate."
"The price of Darktrace is high and could be reduced. We pay approximately $30,000 to $54,000 annually."
"There is an annual license to use Darktrace."
"I am using a demo of Darktrace for deployment and testing which is free."
"The tool's pricing is costly."
"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."
