The NBA passes captured items to a CA DLP policy engine for analysis. The policy engine applies the appropriate user policy to the item. It then calls back to the NBA, instructing it block or allow the item.
In the example below, a user sends a Webmail (1). The NBA (2) analyzes the Webmail and passes it to a policy engine (3) for processing. After applying CA DLP policy to the Webmail, the policy engine instructs the NBA to either allow the Webmail to continue out to the Internet (4a) or to block it (4b).
