For years, business owners in and around Portland have turned to Guardian Systems of Maine for their security needs. While we do emphasize the value of our offerings, we prefer to build relationships rather than make sales. The cornerstone of the security industry is trust, which isn’t something you can simply buy with promotional coupons and competitive prices. Because you are entrusting us with your livelihood, we treat you like a partner rather than just another client. A substantial portion of our business comes from enthusiastic referrals from existing customers – see what they’re saying about us below!
