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

"I find the complete portfolio to be excellent."
"It is a stable solution without downtime."
"The most valuable part of the product is the whole package, as the features included in the Enterprise Immune System are complete and effective and its detection engine is ridiculously good."
"The product is extremely stable and mature."
"One member of staff is enough for deployment and maintenance because Darkforce is AI-driven. It does a lot of things by itself."
"It is autonomous. So, it learns. It uses algorithms and AI to learn the common behavioral patterns on the network, and it is able to identify threats based on abnormal patterns."
"Based on our experience with DarkTrace, I would advise that if they are comparing prices, ROI and everything, I think Darktrace is better than FireEye."
"The AI-based pattern is the most valuable feature."
"It is stable and reliable."
 

Cons

"It's sometimes a challenge getting logs from different sources."
"The only thing that I can think of that would improve it would be if they had a better visualization and a reporting portal."
"It takes time to go through the interface and pick up things. If it were a more straightforward interface, then it would free up time."
"One thing I would like is for Darktrace to flag SMB traffic more accurately. Currently, it only flags that SMB traffic has occurred, but it doesn't specify which file was being transferred. This makes it difficult to investigate incidents involving SMB traffic, as we don't have concrete evidence of what was being sent."
"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 expand into EDR (endpoint detection and response) and combine it with its network detection."
"It is very expensive."
"It should be easier to access the Darktrace portal and its documentation. Only the customer can access their portal and support. It could be cheaper."
"The solution could be less expensive."
 

Pricing and Cost Advice

"Our customers feel that the price of Darktrace is quite high compared to other solutions."
"It is pretty expensive, but it is worth it. Its licensing is yearly."
"The cost is moderate."
"There is an annual license to use Darktrace."
"The product is expensive."
"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."
"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."
"It was $3,600 a month or $2,000 plus or so. I am not sure. Its licensing is pretty simple."
