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.

Helps to detect and generate reports on phishing emails and saves from email compromises
We use the solution for marketing and brand protection.  I am impressed with the tool's discovery capabilities which help me find out who is sending the emails on the company's behalf. I also find the ability to detect and generate reports on phishing emails a valuable feature.  The product's…

Quotes from Members

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

Pros

"We liked their approach to identifying intrusions or network anomalies using AI."
"The most valuable features of Darktrace are its full capabilities, as you have visibility of everything happening on your network, emails, and SaaS applications."
"Provides great network protection."
"While it is complex, and difficult to use, once you understand the correct way to use it, it's a very good platform."
"The most valuable feature has been the behavioral analytics that allows us to monitor all the traffic."
"I find the complete portfolio to be excellent."
"I particularly like Antigena and the analytics around the real-time monitoring of our network. I also like its reporting because it has got a seven-day reporting period within the system. Every time you run the reports, it gives you the data about the previous seven days. I like that because it is in real-time. I enjoy reading those reports and getting a very clear and decisive idea of what's happening on my network on a real-time basis. I like the actual real-time monitoring of spoofing and things like that. I also like the user monitoring as well as the network logging capabilities."
"It is a stable solution without downtime."
"It is really important for large companies to have the brand protection that is provided by Agari."
"If spam or some kind of malicious email gets past Mimecast and gets into our email environment, we can go into Agari and we can search for it."
"Agari offers very good brand protection and they are the core founder of the DMARC standard."
"It comes with a lot of helpful tips for complicated areas."
"Agari gives us visibility of our domain security, helps us manage our SPF, DKIM and DMARC records, prevents spoofing of our domains for phishing and ensures that our marketing and other emails are received correctly and not rejected as spam."
"They are very flexible as far as feature requests go."
"I am impressed with the tool's discovery capabilities which help me find out who is sending the emails on the company's behalf. I also find the ability to detect and generate reports on phishing emails a valuable feature."
 

Cons

"My only criticism of the product is that its licensing model isn't flexible."
"Its documentation is not up to the mark. At times, I have a lot of trouble finding a solution. Even when I posted questions on the community chats, it took a lot of time for me to get answers. That's something that can be improved. Darktrace can focus on creating a more interactive community. If there are more people from Darktrace to focus on community chats, it would be better."
"I believe their network monitoring device licensing module could use some improvement."
"We want to continue using Darktrace but it's very expensive."
"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."
"Darktrace is a closed technology, meaning we know very little about how it works, including the architecture, which is significant. As a result, when we implement the system and find we're getting many false positives, we have minimal insight into why it's happening and what we can do to fix it. We don't know how the solution is configured, the criteria for threats to be determined, or the product's inner workings. We understand that they have to ensure privacy and their copyright, but we want to see some documentation or public research into the security Darktrace provides."
"Its documentation is not up to the mark. At times, I have a lot of trouble finding a solution."
"The dashboard and reporting for this solution could be improved as it is currently complex. The GUI for this solution could also be improved."
"Some customers in the financial sector do not like the cloud solution because they don't want data to be transferred to a US-based cloud."
"The product's user interface is clunky. We have difficulty in finding what we need. I would also like to see automation in the onboarding processes."
"The protocol is quite complicated, which may not be something that could be improved, but it would be better if it was simplified."
 

Pricing and Cost Advice

"Darktrace is expensive. You can pay for the license yearly."
"It is expensive. I don't have the price for other competitors."
"It is pretty expensive, but it is worth it. Its licensing is yearly."
"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."
"When it comes to large installations, it can be expensive, but for small accounts it's fine."
"Prior to negotiating, Darktrace offered their appliance and service for $80,000 per year."
"In the ballpark, we're talking about $30K, $50K, and up. It can even be as much as $50K or $100K."
"It is expensive."
"The tool is not expensive and I would rate its pricing a four out of ten."
"The pricing depends on the number of users; per how many mailboxes you have, but they're pretty negotiable with that, too."
"The price of the licensing is based on the volume of email."
