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

Pros

"The ability to see what we have not seen before is most valuable. It is very interesting to find out the most vulnerable devices in our network."
"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."
"The most valuable features of Darktrace are its full capabilities, as you have visibility of everything happening on your network, emails, and SaaS applications."
"The solution automatically monitors everything on the network to prevent anti-phishing by monitoring, responding, and restoring the system."
