Concepts and technologies are disclosed herein for monitoring and controlling electronic activity. A policy service can be called for policies for controlling electronic activity occurring at one or more managed devices. The policies can include a number of rules, each of which can include a number of variables. The rules can be defined by a manager device and/or received from third parties. Third party rule submissions can be validated. If electronic activity at the managed device deviates from a rule, the manager device can be notified and the electronic activity can be blocked. The manager device can update the policy and/or issue exceptions, if desired.
