Mobile Security

We provide mobile security in marked or unmarked vehicles to businesses for outside perimeter patrol to ensure against theft, break-in or vandalism.

All of our Security Officers have State issued Security Licenses and are fully insured.  Our Officers can accomodate any needs at your venue and can quickly adapt to all situations.

Decision Making Guidance

When sensitive questions arise regarding internal theft, either property or computer related, we assist you in making internal decisions prior to contacting outside authorities. This can help contain or minimize damage to your company or firms image as well as handling sensitive matters internally.
