If a business follows the law and regulations that apply to it it is "in compliance" or "compliant." The department within a business that defines how those laws and regulations will be interpreted and applied within the business - and which polices that staff follow the systems, is called the "compliance department" and the person who makes all of those decisions is the "compliance officer." In most jurisdictions the "compliance officer" has personal responsibility for ensuring that the business and its staff do, in fact, comply.
