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.

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

"Darktrace is a good product and it can be implemented on premises."
"We're very pleased with Darktrace so it is a bit difficult to pinpoint areas for improvement."
"I highly recommend the overall solution to other users and rate it as nine out of ten."
"We liked their approach to identifying intrusions or network anomalies using AI."
"The Antigena feature is very useful."
"It can effectively monitor outbound and inbound devices."

"Trend Micro is a very good product."
"I would rate the solution's stability at ten out of ten."
"I like that it is very user-friendly and easy to install."

"The solution's most valuable features include visibility into the network and fast sandboxing technology for alerts, though response time can vary."
 

Cons

"I would like to see more protection in the endpoint. Especially because we have a lot of people using VPNs. If they would improve end point security, it would give more control there."
"Its threat analyzer could be better. It should also have agents. They should improve this product by installing agents for the machine to get more visibility. Currently, they are monitoring only the network. They should also monitor the agents from inside. It should also have a better pricing plan because it is an expensive product."
"There is no dedicated salesperson in Egypt, and having one would help to improve focus on this market."
"They are too expensive compared with other vendors."
"There are still some issues with the network capturing or blocking traffic even after implementing exceptions. It requires more learning in this area."
"It is expensive, but everything else has been great so far."
"Needs to improve its collaboration with local partners."
"If asked to rate Darktrace support on a scale from zero to ten where ten is the best, I would give them five points."
"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 Deep Discovery Email Inspector could improve by making it easier to use. Microsoft solutions are easier to use."
"The product's feature for message processing and blocking devices for bulk emails needs improvement."
"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."
"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)."
"To improve Trend Micro Deep Discovery Email Inspector, it should have updates with better AI and ML-based integration."
"The dashboard could be improved to match the quality of Check Point Harmony's dashboard."
"Trend Micro's technical support has room for improvement. More efficient support should be provided, especially for standard support."
