The GSI Difference

It’s simple. We customize our security services to meet the specific needs of each customer & we invest in customer support rather than bloated corporate bureaucracies.

Here’s what that means for you:

We work with you to develop a custom training program so guards present themselves to fit your brand.
We provide each client with a dedicated customer service manager whose job it is to ensure we are exceeding your expectations.
We are very responsive and have a proactive management approach that enables us to consistently meet the customer’s needs so issues are resolved quickly and efficiently.

Oh yeah… and did I mention we have the lowest turnover rates in the industry. That’s because we hire carefully and take care of the people who will be greeting and protecting your tenants, staff, clients and property.
