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

"It's beneficial to me and I can see that with more time and energy put into optimizing it and personalizing the unit, it can be much more powerful than the way I am using it now."
"A very useful feature in Darktrace for real-time threat analysis is the packet inspection that analyzes the packet traffic in real time."
"I have found the automation and AI features to be valuable. If someone were to come in to the office at midnight and log in, Darktrace would flag it."
"It is really good; it has given us a view of our company and it has actually caught a couple of people that were doing data exfiltration and stealing data from our company, and we caught them doing it in the act in live time, which is just incredible."
"Its AI technology supports cybersecurity by learning my environment and accurately responding to threats."
"The most valuable feature has been the behavioral analytics that allows us to monitor all the traffic."
"AI analytics are built directly into the product."
"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 stable and reliable."
 

Cons

"I think there is some MSSP missing."
"The stability isn't good but I like the product."
"The level of tracking within the network from the transmission level up to the machine level can use improvement."
"In an upcoming release, there could be more customizable playbooks or a library of playbooks to choose from."
"The solution's user interface and stability could be improved."
"Its threat analyzer could be better. It should also have agents."
"The initial setup is more complex and time-consuming than some solutions."
"Darktrace needs to automate the reports of false positives, botnets and everything."
"The solution could be less expensive."
 

Pricing and Cost Advice

"It's an expensive solution."
"This solution is expensive."
"In the ballpark, we're talking about $30K, $50K, and up. It can even be as much as $50K or $100K."
"Our customers feel that the price of Darktrace is quite high compared to other solutions."
"The product is expensive."
"Darktrace is pricey, but the price is reasonable for what the solution does, and it's comparable to other products."
"It is a very expensive product."
"All of the other modules, such as the licensing modules, are on par. It's one for one."
