Last Friday Trend Micro released Deep Security 8.0 Service Pack 1. 
The most significant changes in SP1 are:
- On Demand scan agent based anti-malware on Linux. Supported versions are Red Hat Linux 5, 6 (64 bit only), Suse Linux 10, 11 (32 and 64bit)
- Protecting ESX 4.1/ESXi 4.1 hosts with Deep Security 8.Deep Security can now provide protection for virtual machines running on ESX/ESXi 4.1 and 5.0. You can use the same Deep Security Virtual Appliance in combination with the proper version of the Filter Driver.
- Improved anti-malware scan exclusions.Exclusions were only possible for files. Now directories, files and file extensions are supported for the anti-malware scan, either by listing them specifically or through the use of wildcards.
- More Localization. The manager is now also available in Japanese and Simplified Chinese. The agent and notifier are also localized in German, French, Spanish, Italian, Russian, Japanese, Korean, Simplified Chinese and Traditional Chinese.
When you have installed Deep Security 8.0 it will automatically warn you that an update is available. Since it was only released a couple of days ago there is little information available about the update. As with all updates, test it on a small scale before deploying it to your full environment.
