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.

The solution is useful for monitoring network devices, but the interface is old-fashioned
The solution is useful for monitoring network devices We use it for up-and-down monitoring features. It’s an old solution. It has an old-fashioned interface. The product must provide a compliance testing feature. I have been using the solution for six years. I rate the tool’s stability a ten…

Quotes from Members

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

Pros

"Darktrace is very useful for us because it has a large number of models for detecting threats."
"The solution automatically monitors everything on the network to prevent anti-phishing by monitoring, responding, and restoring the system."
"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."
"It has helped the organization to detect any malware affecting the machines...The network monitoring and the email monitoring features are very valuable for us."
"The Antigena feature is most valuable. Once it learns your environment, Antigena can step in and block a denial of service attack, a ransomware attack, or just about anything that doesn't belong in the environment. It can detect any type of attack that hits the environment because it understands what normal looks like for the network. It is very useful for an autonomous response."
"The support was fantastic, really good."
"Darktrace played an important role in the security detection strategy by reducing the time lost in detecting, analyzing, and incident resolving."
"The most valuable feature of Darktrace and the most valuable feature is the artificial intelligence module because that is the tool that determines automatically if there is any risk or not in the network."
"The solution offers very good system monitoring; it's easy to manage your network, as well as your hardware and software, and it's really useful."
"Network tracking is the most valuable feature of Network Analyzer."
"Since we have been using it for the last five years we have done very well with reference to ROI."
"This is a product that I can recommend."
"The network monitoring feature, especially, stands out to me."
"The tool's UI is user-friendly, and pricing is affordable. It is very easy to deploy and learn."
"Our customers like this product due to the fact that it's quite simple and it can be integrated with other solutions that complement and complete each other."
"The initial setup is easy."
 

Cons

"Darktrace needs significant improvement in its notification capabilities."
"The level of tracking within the network from the transmission level up to the machine level can use improvement."
"The stability isn't good but I like the product."
"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."
"The pricing needs improvement."
"The user interface and the configuration are a bit complex and should be improved or simplified."
"As of now, I feel Darktrace can be improved to better detect end device activities, such as laptops or desktops, to bind it with our network."
"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."
"It's very hard to install materials. You need a lot of documentation. They should make it easier to install and configure the solution."
"The graphics and reports can be a little bit better."
"I think the reports can be improved. They're adopted."
"There are some loopholes you need to be aware of from a security perspective."
"There is room for improvement on the setup side."
"The bandwidth for its front-end version needs enhancement."
"Nagios Network Analyzer should integrate an application monitoring solution to monitor application bandwidth usage."
"It has an old-fashioned interface."

"The pricing is expensive. It costs over $100,000 a year."
