Suspicious outbound content is typically quarantined until it can be examined by security personnel. The quarantine process is tedious and stops or delays the flow of legitimate business transactions. (In this case, suspicious means it violates company policy, contains private information, is addressed to certain recipients, etc.)
One solution is to provide automated, policy-based encryption of outgoing messages as a component of content control systems. Automated encryption technologies evaluate outbound content and encrypt and transmit that content according to corporate policy. Such selective encryption should be automatic and transparent to the end user. For example, if private HIPAA medical data is detected in an outbound email, the system should encrypt it before sending it on without requiring any user action.
Content control vendors need to partner with encryption vendors to provide this service. An early indicator of this trend is a new partnership combining the content control features of Reconnex's iGuard with the automated encryption capabilities of PostX's Messaging Application Platform.
