What clients
are saying


Protos is the only guard company where I constantly receive compliments on the level of service they provide. Plus the technology they bring to the table is unmatched. We have experienced a 5% savings because of time worked being properly billed and reported.

Protos has always delivered what they say. When we call for emergency service, they constantly communicate with us until the request is filled. Compared to our previous provider, they are great communicators and I have and would highly recommend them to anyone.
