Coming soon will be Trend Micro Deep Security 9.6 and will bring some news. In addition to full support for vSphere 6.0 and 6.1.4 NSX, new agents appear to support the new Linux distro:
Debian 6 i 7, Cloud Linux 7, Oracle Linux 7, SuSE Enterprise Linux 12
There will also support for Windows 2012 Server Core. I must admit that I personally most pleased that Debian support. This platform was our first choice (before we went on Ubuntu and CentOS), and still many systems are based on Debian. What is interesting, from an Trend Micro FTP server you can download the installation files for all the agents in version 9.6 (including those for Debian). You can safely install these agents (work with DSM 9.5 sp1).
As you can see, the Debian agent works without any problem. Readme file for DSM version 9.6 you can review here.
