Room For Improvement

Cisco Secure Email faces complex UI, integration issues, high costs, and lacks advanced features, affecting usability and scalability.
Darktrace needs improved integration, automation, usability, pricing, support, and clarity, plus better endpoint protection and third-party tool integration.
The solution should better analyze the actual content rather than only focusing on the email header or origin.
Chief Information Security Officer at Abcl
It would be beneficial to have the functionality of the Email Threat Defense integrated into the Email Security Gateway so customers don't have to buy two products for full email protection.
Systems Engineer at a non-tech company with 51-200 employees
It may take nearly an hour to get back to normal while configuring policies.
Technical Associate Network Security at Valuepoint Systems
There is no dedicated salesperson in Egypt, and having one would help to improve focus on this market.
Solution Architect at a tech services company with 51-200 employees
They say they can integrate with most firewalls, but when we did an integration with Meraki MX firewalls, that integration didn't work and still doesn't work to this day.
Security Analyst at a healthcare company with 10,001+ employees
We need Darktrace on each branch to get the data out, and I suggest having some kind of a centralized product that gets data from multiple sources to aggregate and provide the data.

Valuable Features

KS
Technical Associate Network Security at Valuepoint Systems
Email security has protected financial data and provides clear tracking for every branch message
The areas of Cisco Secure Email that could be improved or enhanced are the slowness in the console. I don't think it was a database error or something, but we feel some slowness in configuring DLP and other content filters compared to other consoles. It may have been due to on-premises, but it was much noisy at some times while configuring DLP. When we tried to configure a DLP policy, the console became much slower. In that case, we cannot see what had happened in the mail which was blocked at that time. It may take nearly an hour to get back to normal while configuring policies. That is the major issue in the product.
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.
