DLP recommendations
• Rules related to HTTP posts can be created, but if the requirement is to block all HTTP posts, a better solution is to use application control or the HTTP POST Action option in the web filter profile.
• While DLP can detect sensitive data, it is more efficient to block unnecessary communication channels than to use DLP to examine it. If you don’t use instant messaging or peer-to-peer communication in your organization, for example, use application control to block them entirely.
