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

"A simple, powerful AI solution that just does all the work for you when you turn it on."
"This solution can reduce the resources required to run a security operation center by two-thirds."
"The most valuable feature is that it works autonomously."
"Darktrace is very flexible."
"Because of unsupervised machine learning, its detection capability is quite good."
"The most valuable feature of Darktrace is the AI that detects abnormal network activity."
"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."
"The models, triggers, and alerts are customizable."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"The most valuable feature is the straightforward setup."
"The primary use case of this solution is to filter emails and only allow the legitimate ones through."
"You can install the plugins on the same machine hosting your exchange solution. It's a good complement for Sophos security, which scans the traffic before it reaches your mail service. Kaspersky is on the mail server itself while Sophos handles the incoming traffic. With both of them working together, we have the perfect solution for mail."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"The most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."
"The integration rate is very high in Kaspersky, which is why most of our customers like it."
"Kaspersky Security for Mail Server provides protection against email spams and blacklisted emails which are suspicious, making it a good product."
 

Cons

"The cost is a bit on the higher side."
"The cost of the solution is quite high."
"Updates keep coming, which is great, but I prefer a unified UI experience. The intelligence section and the incident view should be seamlessly connected in one view to avoid jumping between pages."
"I was under impression that Darktrace's automatic blocking would be an out-of-the-box feature, but we had to integrate it with our firewall to get it to block automatically. The salesperson should be upfront and explain that you need to integrate it with your network. I would also like to see more reporting on risk. Banks in my region want to see at a glance the risk level of various assets."
"It would be good if they can include some endpoint protection for remote workers."
"The main portal needs improvement as it is difficult to use."
"Darktrace could improve by being more user-friendly."
"The one downside is the pricing, which is quite high."
"The biggest problem in the solution is related to its license renewal since it is pretty hard in Kaspersky to find out the procedure to renew a license."
"The stability of Kaspersky Security for Mail Server is okay, not so much of an issue."
"It would be great if Kaspersky could do what Sophos does for us. However, we love having these two different technologies doing the same thing. Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."
"The solution is not 100 percent stable and that can use improvement."
"I have only made contact via email, and it is a little slow. I would give customer service a rating of six or seven. Improving Spanish support would greatly benefit users."
"Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
 

Pricing and Cost Advice

"The pricing is expensive. It costs over $100,000 a year."
"The pricing is a little high compared to the competition."
"There is an annual license to use Darktrace."
"Darktrace is expensive. You can pay for the license yearly."
"The price of the solution is not cheap. It is not a one-time purchase, there is a subscription that needs to be paid every one to five years depending on your choice. It is expensive but you can reduce the price by only using the services that you want."
"If you consider the features and the cost of market leaders, we are satisfied with the pricing."
"All of the other modules, such as the licensing modules, are on par. It's one for one."
"We've budgeted about 50,000 Kuwaiti dinars for the solution. That is a yearly operating cost."
"My company makes annual payments towards the licensing costs solution."
"The solution is not expensive."
"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."
"The solution offers one of the best prices possible to its users, making it even better than Barracuda. Kaspersky Security for Mail Server is ten times cheaper than Barracuda."
