Network Security Consultant at NTT DATA
Centralized policy governance has reduced audit effort and continuously improves risk visibility
I wish to see deeper and more customizable reporting and dashboards, as while the standard reports are useful for audits, operational teams sometimes need real-time, flexible views without exporting data. Tighter integrations with ticketing and change management tools would also enhance the workflow from request to implementation. FireMon Security Manager is excellent for policy governance and risk reduction, but better real-time dashboards and stronger workflow integrations would make it even more powerful for daily operations. There are one or two areas where FireMon Security Manager could be improved to make it even stronger. While FireMon Security Manager overall delivers solid governance and risk insight, it would benefit from more flexible dashboards and deeper integrations to reduce manual steps and improve visibility without relying on external tools. I rate FireMon Security Manager an 8 out of 10. It is a strong tool for firewall policy management, risk analysis, and compliance, clearly improving our audit process and policy governance. The reason I do not give it a 9 out of 10 is mainly because the dashboard could be more flexible and integration with the firewalls could be smoother. FireMon Security Manager is a reliable and high-value platform for managing and governing firewall policies, especially in a multi-vendor environment, though a few areas can still be improved.

Centralized management has streamlined access for staff and support has consistently addressed issues quickly
I see areas for improvement, particularly around the SSL VPN. It is a tool that we have used quite heavily, but it has a lot of vulnerabilities and they are starting to be dropping support for it. So we kind of see that they have left a vacuum by removing that feature. The VPN feature is indeed the main concern so far. Security around it is a concern, and then the fact that they have just dropped it and have not really provided a solution that fits for us. Their solution was either IPsec or ZTNA, which is not as flexible as the SSL VPN was for our customers.
