While the Public security sector works on behalf of general interest, the private sector operates and focuses on private interest. And here is the major difference between the purpose of service between the two professions, Police and Security Guard. The other differences are clear in their licensing, operations, requirements, power, structure, etc. 

As clear and explicit as these differences are, these two professions are not in any way contradictory, rather, they are closely related. Due to this, there are few opportunities for practitioners of the two professions to legally cross-train, network, benefit, and make a meaningful income.

The general assumption is true. Being a police officer places you at a higher advantage, even at interviews. You will be considered first before others. Your answering skill is going to be top-notch because you have greater practical training and experience at these things. So, cross-training is more perfect when you are an officer first, before a private guard. 

Becoming a police officer is highly tedious, rigorous, and as such, highly competitive. Should you decide to upscale your career from a private guard to a police officer, your training and work experience as a private guard places you at a competitive edge in passing examinations, tests, interviews and even excelling at training. 

Moonlighting: Police officers and guards cross-train and network

Moonlighting is one common and great means to be “the man in the two roles” and getting paid. Some state departments permit their police officers to work as private security officials at off duty security jobs. This means that, if you are a police officer, you can work as a private guard when you are off-duty. Another benefit that comes with moonlighting is that you get to wear your ‘cop uniform’ even while you are working as a private guard.

Moonlighting is always supported by the departments and in most cases, the departments always serve as the go-between the moonlighting officers and the private companies. 

Truthfully, the difference between the two professions is glaring but the similar nature of the job brings the practitioners to network in several ways. Through crime and issues report, training, interactions on the field, case solving, etcetera.
