The employer decides how and why monitoring happens and remains responsible; it should not assume purchased packages or third-party software are compliant or designed with data protection in mind, and before starting it must ensure the system complies and that necessary contracts are in place. A provider acting only on written instructions is likely a processor; the employer must ensure it is competent and compliant and bind it by contract (or another legal act) setting out each side's responsibilities.
This control maps to 1 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 1 it maps to, and the evidence behind each claim, over MCP and REST.
