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.

Straightforward to set up, reliable, and offers good functionality
We primarily use the solution for email security and general email management.  It's improved our productivity.  The solution works well overall. The functionality is very good.  The setup process is easy.  It is stable and reliable. It's scalable.  I don't have any specific areas that need…

Quotes from Members

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

Pros

"The most valuable feature is the solution's ability to trim out the false positives and point your attention to the real important stuff."
"The most valuable feature of Darktrace is its ability to detect and counter threats before they occur."
"In terms of features, the data or information they collect and unsupervised machine learning are very valuable. Its unsupervised machine learning has reduced our team's effort. Both Darktrace and Vectra work on unsupervised machine learning that learns the behavior or develops a profile on its own, which allows our security team to do some other tasks rather than spending time on Darktrace or Vectra. Because of unsupervised machine learning, its detection capability is quite good. Along with that, if we utilize the integration feature properly, the automated incident response capability of Darktrace is quite useful."
"The product is extremely stable and mature."
"Provides great network protection."
"Darktrace has improved our knowledge of abnormal phenomenen which could have potentially be hazardous for the organization."
"Darktrace played an important role in the security detection strategy by reducing the time lost in detecting, analyzing, and incident resolving."
"Darktrace is extremely stable."
"It is stable and reliable."
 

Cons

"The solution could be easier to use."
"I would like for the product to work on the endpoints as well. I would like to see enhanced visibility into the endpoints and network but this solution only sits on the network itself."
"They just need to work on their price."
"The pricing model is a little too high and could be more flexible."
"There aren't so many third-party vendor platforms natively integrated with the platform."
"In terms of improvements, fine-tuning is the area where we have to spend some time because it works on unsupervised machine learning. It would be good if they can improve their algorithm or technical functionality to reduce the fine-tuning effort. They can also come up with something at the endpoint level. So far, Darktrace has been a network detection response (NDR) solution. It does not offer much at the endpoint level or on user-client devices or servers. There should be more visibility at the endpoint level. It would be good to have the detection and response at the endpoint level by Darktrace. It should also have integration with an agile environment so that we can have continuous development and continuous integration in the application development environment. This is currently not there. It should also have internet-facing platform visibility, which is currently missing. They also need to improve the reporting and management dashboards. Currently, these are not so easy for a non-technical person. All these features would make Darktrace much better, and they would also be helpful in selling more solutions."
"Darktrace could expand into EDR (endpoint detection and response) and combine it with its network detection."
"The initial setup is a bit complex."
"The solution could be less expensive."
 

Pricing and Cost Advice

"The product is expensive."
"It is expensive. I don't have the price for other competitors."
"It is pretty expensive, but it is worth it. Its licensing is yearly."
"We had an issue with pricing initially and had to cancel some of the features of the projects to fit the budget. I would like to see pricing that is not broken up into parts so that we can buy the whole package once. Darktrace is more expensive than an average solution, but it's functionality won't match that of an average solution."
"Darktrace is quite an expensive solution."
"The cost is moderate."
"If you consider the features and the cost of market leaders, we are satisfied with the pricing."
"It is inexpensive considering what it can do and the competition."
