Frequently Asked Questions

Why should we outsource our security and not have our own security division?

Security is not an easy field and the needs of a security division are often quite different than the needs of the rest of the business. Hiring a security guard from a security guard company alleviates the overhead cost that having a security team would otherwise bring.

Are Background checks performed on all of your guards?

Absolutely! Background checks are just one of the many ways that Armstrong Guard ensures that we’re hiring the best of the best. We always want to staff you with the best guards we can find and part of our selection process involves rigorous background checks.

Is Security Necessary?

In San Bernardino security is essential for the success of your business. It’s one of the most violent cities in the United States. Protect your business will be essential, especially if you’re in a less than safe part of town.

Will armed security make customers or guests feel uncomfortable?

There’s always the possibility that guests or customers respond poorly to seeing an armed guard. The mood and customer experience you’re trying to cultivate is part of what we consider when we recommend a type of guard to our clients and we can talk with you about what works best for you and your business.

Are Unarmed Guards Enough?

It depends on the type of business you have, the risk your business is under, and your location. These are all factors we consider when making recommendations to our clients about their security needs. Often unarmed guards are enough but sometimes that’s just not the case. An unarmed guard is better than no guard.
