Trend released WFBS earlier this year and it’s been pretty solid so far. Since that time they’ve released 3 patches that you need to consider applying.
Each of the patches only takes a few minutes to apply, so it’s not really a big deal at all. I’d recommend you install them regardless of deployment method. You can download the patches here
After patching you will see the Hot Fix list as below
|B1433||760KB||Needed after in place upgrade to ensure SmartScan server functions correctly.|
|B1439||7.19MB||Fix for HeartBleed vulnerability|
|B1452||2.1MB||Resolves issue with CSAs not starting up if you used AutoPCC to deploy them|
