Room For Improvement

Cisco Secure Email's high cost, complexity, poor interface, and limited integration impact usability, requiring AI and service enhancements.
Users seek better SIEM integration, improved automation, user-friendly interfaces, and enhanced protection with more intuitive reports and dashboards.
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.

There is no dedicated salesperson in Egypt, and having one would help to improve focus on this market.

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

Systems Engineer at a non-tech company with 51-200 employees

Security Information & Incident Analyst at a financial services firm with 1,001-5,000 employees

Featured Reviews

BD
Chief Information Security Officer at Abcl
Threat intelligence with fast attack detection enables comprehensive email protection
In some cases, detection is missed, leading to false positives where genuine emails are flagged as spam. This could result in users not opening genuine emails. We have highlighted this to Cisco because sometimes phishing or marketing campaigns, which are genuine, are incorrectly flagged as spam. The solution should better analyze the actual content rather than only focusing on the email header or origin.

Consistent threat hunting and anomaly detection deliver valuable insights for network security management
In terms of improvement for Darktrace, pricing is the main concern. Pricing bothers me and this is one of the major factors when choosing a solution. When we get feedback from customers, that's the only felt need. When we factor in Darktrace, we do it only limited. We put it on where the perimeters and connections are, but still, some gray areas are left out, especially if we have multiple branches. 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.
