Featured Reviews

Malebo Lethoba Group - PeerSpot reviewer
Have found the AI analyst and detection functions highly valuable for network operations while managing complexity in initial setup
The functions I find most valuable in Darktrace are the AI analyst as well as the detection.The autonomous response capabilities of Darktrace are not crucial for me because it doesn't work in a network where there are no core switches. In a modern network, the autonomous response doesn't work, especially when sitting in a shared data center.If I'm running a traditional network where I am not in a shared data center with a layer two dedicated for my resources, then it can work for me. However, if I am in a data center where I don't have layer two, it becomes an issue because the autonomous response is reliant on sending spoofed TCP resets to my core switch to block traffic, which is a major issue.
Bilal Saleem - PeerSpot reviewer
Reliability and threat intelligence make this solution competitive, but AI improvements can further enhance its effectiveness
The best features of Trend Micro Deep Discovery Email Inspector include its reliability. The second valuable feature is its built-in sandbox feature, allowing for inspection of incoming emails and attachments. The sandbox is an appliance that opens any attachment in an enclosed environment to assess its impact and potential for viruses. This protects the network from harmful threats. Trend Micro has a very large R&D team with excellent threat intel, allowing them to provide better solutions than some competitors. They understand emerging threats based on the information from their EDR. The key strengths can be summarized as reliability, a good integrated one-box solution that includes a sandbox, and their R&D capabilities and good ratings, which lead to better threat intelligence. The detailed threat intelligence provided by Trend Micro Deep Discovery Email Inspector is valuable in understanding the behavior and tactics of potential email threats.

Quotes from Members

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

Pros

"I can rate Darktrace's technical support as one of the best products in the world."
"The most valuable feature is the alerts. The alerts are meaningful. The event rolls up into meaningful and actionable alerts rather than just being noise."
"The most valuable feature of this solution is that it does not require human intervention to eliminate a threat."
"The autonomous response is also highly designed in Darktrace."
"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."
"What I like about Darktrace, is that you can quickly identify threats."
"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 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."
"I like that it is very user-friendly and easy to install."
"Trend Micro is a very good product."
"The best features of Trend Micro Deep Discovery Email Inspector include its reliability."
"I find Trend Micro to be a good solution for security purposes."
"The most valuable feature of Trend Micro Deep Discovery Email Inspector is the simple analysis of phishing emails."
"I highly recommend Trend Micro Deep Discovery Email Inspector due to its security and scalability features."
"It can effectively monitor outbound and inbound devices."
"I would rate the solution's stability at ten out of ten."
 

Cons

"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."
"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."
"I'd love them to see maybe covering the cloud a bit more."
"I would like to see some additional enhancements."
"This is quite an expensive product so the pricing is something that can be improved."
"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."
"The solution can improve the reporting."
"The main portal needs improvement as it is difficult to use."
"It could be more user-friendly, easier to install, and lighter on the network. I would say that for all products because you do not need technical expertise to take care of it. When you have a user-friendly solution, it makes it easier for the vendors or companies like us. We do not have to go to the client's site to attend to issues all the time. Because it is user-friendly, they can take care of it after some training."
"Trend Micro's technical support has room for improvement. More efficient support should be provided, especially for standard support."
"Trend Micro Deep Discovery Email Inspector could improve by making it easier to use. Microsoft solutions are easier to use."
"I would like to be able to send emails to a specific sandbox. This is a feature I would like to see added to the next release."
"Trend Micro's technical support has room for improvement."
"The dashboard could be improved to match the quality of Check Point Harmony's dashboard."
"The tool needs to incorporate faster response times for issue detection, more detailed reports, and better compatibility with older operating systems (e.g., Windows 7, 8, Server 2012)."
"The product's feature for message processing and blocking devices for bulk emails needs improvement."
 

Pricing and Cost Advice

"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."
"Darktrace is quite an expensive solution."
"It is pretty expensive, but it is worth it. Its licensing is yearly."
"The cost of the solution can be reduced to make it more appealing to customers."
"It was $3,600 a month or $2,000 plus or so. I am not sure. Its licensing is pretty simple."
"Darktrace is pricey, but the price is reasonable for what the solution does, and it's comparable to other products."
"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."
"We pay for an annual subscription for this email security solution."
"The price of Trend Micro Deep Discovery Email Inspector is less expensive than Microsoft solutions."
"The solution's pricing is high, and I would rate it an eight out of ten."
"It's an expensive solution, and you may not see a return on investment in a short period of time. However, you will see a return over a long period of time."
