We offer a full range of security guard services, including alarm response, security patrols, standing guard, fire watch, lobby reception security, logistics, package receiving, and more.

In addition to being highly trained, vigilant, and professional, our security guards are available on both a short- and long-term basis in North Hills, Porter Ranch and Granada Hills. As such, they can be hired for just a few hours, a few days, or for an ongoing, unspecified amount of time. When hired to provide long-term security, our guards become even more effective as they integrate with your community or business. They learn to more easily identify when people, things, or activities are out of place and gather greater knowledge of their role in supporting your security needs.

Effective Security Guard Solutions for Locations Throughout Granada Hills, North Hills, Porter Ranch, and Surrounding Los Angeles Cities

While this part of Los Angeles County maintains a relatively low crime rate, property crimes such as burglaries and vandalism are still a top concern. In fact, those located near the 405 and 118 freeways are usually at a higher risk because these locations allow criminals to make a quick getaway. Like any community, there are always criminals looking to take advantage of vehicles with visible purses or other possessions in them, retail stores with lots of inventory, construction sites with valuable materials and equipment, parking lots with minimal lighting and a multitude of corners to hide in, unwatched buildings, stores, and homes, and more. To discourage vandalism, trespassing, thefts, burglary, as well as assaults and unruly behavior, book our security guard services for your property in the Granada Hills, Porter Ranch, North Hills or other nearby area.
