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.

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

"It's a very stable product."
"It is a very simple product to use."
"The features that are most valuable to me include detection, response with analytics, and network detection."
"They've worked hard to be the top security control in terms of AI and machine learning, and their product works well."
"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 provides a comprehensive cybersecurity solution that monitors my cloud accounts as well as my local network."
"The Dynamic Threat Dashboard is very nice, as it lists all of your threats and rates them, and then you can choose whether to investigate further."
"The product can scale."
"It is stable and reliable."
 

Cons

"Its threat analyzer could be better. It should also have agents. They should improve this product by installing agents for the machine to get more visibility. Currently, they are monitoring only the network. They should also monitor the agents from inside. It should also have a better pricing plan because it is an expensive product."
"The price point for the product was too high for what our possible use case could be."
"I believe their network monitoring device licensing module could use some improvement."
"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."
"The product doesn't have an endpoint agent that can react to triggers set on the device,"
"One area for improvement is the alerting system, which generates too many alerts and becomes labor-intensive for organizations not equipped with enough personnel in their SOC."
"In the next version, I'd like to see penetration testing."
"The interface is too mathematical and it should be simplified."
"The solution could be less expensive."
 

Pricing and Cost Advice

"Darktrace is expensive. You can pay for the license yearly."
"The product is expensive."
"They are too expensive compared with other vendors."
"All of the other modules, such as the licensing modules, are on par. It's one for one."
"It is inexpensive considering what it can do and the competition."
"The cost is moderate."
"It's an expensive solution."
"Darktrace is quite an expensive solution."
