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

"We are able to detect a lot of things, actually, and see what is happening in our network."
"The product can scale."
"While it is complex, and difficult to use, once you understand the correct way to use it, it's a very good platform."
"Artificial intelligence and machine learning functionalities are valuable."
"The initial setup is simple."
"The investigative part of Darktrace is valuable, especially the automation features. It allows setting up checks and provides guidance on mitigating situations, which is very useful. There are different modules that you can add to the console for protection."
"Provides great network protection."
"We allow customers to access our Wi-Fi as guests, and some of them were going to restricted sites. Darktrace showed us what they were doing so we could block them."
"It is stable and reliable."
 

Cons

"Darktrace is a closed technology, meaning we know very little about how it works, including the architecture, which is significant. As a result, when we implement the system and find we're getting many false positives, we have minimal insight into why it's happening and what we can do to fix it. We don't know how the solution is configured, the criteria for threats to be determined, or the product's inner workings. We understand that they have to ensure privacy and their copyright, but we want to see some documentation or public research into the security Darktrace provides."
"I would like to see some additional enhancements."
"The price point for the product was too high for what our possible use case could be."
"In a shared environment, it doesn't work, and there are still some integration issues."
"The pricing is costly in USD, and they charge based on device counts."
"They are too expensive compared with other vendors."
"It would be good if they can include some endpoint protection for remote workers."
"I would like to see a feature where the tool ingests information from an anti-malware product that is present at the endpoint."
"The solution could be less expensive."
 

Pricing and Cost Advice

"If you consider the features and the cost of market leaders, we are satisfied with the pricing."
"It was $3,600 a month or $2,000 plus or so. I am not sure. Its licensing is pretty simple."
"It is a very expensive product."
"Prior to negotiating, Darktrace offered their appliance and service for $80,000 per year."
"The cost is moderate."
"The pricing is quite high, estimated at around $350,000 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."
"It is expensive. I don't have the price for other competitors."
