What is Outbound Content Compliance? Outbound Content Compliance (also outbound content security or OCC) is a new segment of the computer security field, which aims to detect outbound content that violates the security policy of the organization and/or government regulations and prevent it leaving the organization. OCC deals with internal threats, either malicious or accidental, as opposed to more traditional security solutions (firewall, anti-virus, anti-spam etc.) that deal with external attacks. Therefore, it is sometimes called inside-out security. OCC solutions are designed to detect and prevent the accidental sending of sensitive and confidential information outside the organization while at the same time educating information workers on the organization‟s security policies and industry and/or regulatory compliance requirements.
