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.

Quotes from Members

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

Pros

"The Antigena feature is very useful."
"While it is complex, and difficult to use, once you understand the correct way to use it, it's a very good platform."
"Its AI technology supports cybersecurity by learning my environment and accurately responding to threats."
"The technical support is excellent; they walk you through the process and do a great job."
"We allow customers to access our Wi-Fi as guests, and some of them were going to restricted sites. Darktrace showed us what they were doing so we could block them."
"The most beneficial feature in Darktrace is identifying phishing emails with the help of the AI engine and machine learning."
"The most valuable feature is the endpoint protection."
"It is really good; it has given us a view of our company and it has actually caught a couple of people that were doing data exfiltration and stealing data from our company, and we caught them doing it in the act in live time, which is just incredible."
"It is stable and reliable."
 

Cons

"The price point for the product was too high for what our possible use case could be."
"The pricing model is a little too high and could be more flexible."
"It's a very complex platform."
"Needs to improve its collaboration with local partners."
"They just need to make it a little bit more accurate as far as their alerts are concerned. It does generate some false positives that you have to tune. You have to do a lot of tuning when you first get it because of the false positives, but once it is all tuned up and ready to go, it will do its thing from there."
"With Darktrace, at the moment, I have to almost put in a date and tell them that I want you to give me data from this date to this date."
"Darktrace could improve by being more user-friendly."
"The solution can improve the reporting. Currently, it only runs weekly and the reporting is complex."
"The solution could be less expensive."
 

Pricing and Cost Advice

"Darktrace is pricey, but the price is reasonable for what the solution does, and it's comparable to other products."
"When it comes to large installations, it can be expensive, but for small accounts it's fine."
"They are too expensive compared with other vendors."
"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."
"I'm unfamiliar with the exact cost, but we have a yearly license and had to pay for Darktrace's services before the deployment. The product is very expensive, so some organizations can't afford to pay the total amount directly, meaning they often seek a partner or pay in installments, which increases the price more."
"We've budgeted about 50,000 Kuwaiti dinars for the solution. That is a yearly operating cost."
"It's an expensive solution."
"The cost of the solution is expensive for smaller businesses. They will not be able to afford it or might not need this type of security solution."
