I am using McAfee ePo and I am very satisfied with it. I use HIPS and VirusScan for my Windows Servers.
For the HIPS, I only use the firewall feature, and its great. I saw that McAfee has a VirusScan for Linux but I didnt find any firewall solution. Does anybody know any that can be integrated to ePo and acts like a Firewall for Linux endpoint ?
