Licensure and registration are based on meeting general eligibility requirements. Maine does not currently mandate training or testing. Individuals who operate security agencies go through a licensing process. Licensees are responsible for making sure that their employees meet requirements set by the state.

Maine does not have a credentialing process for armed security officers. Gun laws are less restrictive than in many states. However, some employers may require permits even when not mandated by law.
