Deployment Mode 
Caveat 
All
Cisco does not recommend enabling automatic updates. See 
RSA Email DLP 
DLP updates may change the content matching classifiers used by your 
existing local DLP policies. Cisco recommends that you manually download 
DLP updates to an appliance in a lab environment to test your DLP polices 
before updating appliances used in production. 
RSA Enterprise 
Manager DLP
Downloading DLP updates to your local appliance does not change the 
content matching classifiers used in your DLP policies, which are 
configured using Enterprise Manager. However, if you later switch your 
appliance to use RSA Email DLP, any existing local DLP policies will use 
the updated classifiers.
