Room For Improvement

Cisco Secure Email's high cost, complexity, poor interface, and limited integration impact usability, requiring AI and service enhancements.

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.
Steve Bradbury - PeerSpot reviewer
Consultant at Exelixis Inc
Email defenses have blocked advanced threats and provide deep visibility into risky users
The areas that have room for improvement in Proofpoint Email Protection include their cost of ownership, which is fairly high. To manage and run all their products, I have to list and manage administrators in seven or eight different places. That is too many places to keep track of since for this tool I have to go to one location, and for another tool I have to go to a different location. They need to simplify the administration management of administrators and consolidate that into one place for all their products. Access to all the different products is very scattered. For some products I go to one URL, and for different products I go to a different URL. They have a threat URL that has most of their products in it, but not all. They need to simplify the interface to show all the products I have access to in one location.
