Before the term “security guard” was used, those people who were charged with guarding private and public places were known as “watchmen.” Historians and researchers believe that this exciting career dates back to at least the middle ages, and security personnel were most like employed by the Romans, Greeks, and Egyptians.

Modern security guard agencies and security companies of some form can now be found in a wide range of specialties in every country in the world. As such, there are different types of security guard agencies that serve in a variety of functions. This includes everything from school and mall security to military police and the U.S. Secret Service.

Given the fact that large businesses have highly confidential materials and information to protect, many companies are now hiring security guard agencies to insure that unwelcome guests do not gain access to privileged materials. Although commercial security companies still provide a physical presence in the buildings and areas owned by the entities with which they are charged to protect, cyber security has been one of the most rapidly growing specialized security services.

As the cyber world has become inundated with unsavory individuals looking to take what doesn’t belong to them, online security has become one of the most crucial components of company security. Therefore, computer security specialists are now part of the staff at any top commercial or private security company. By enlisting the services of a leading security agency, business can rest assured that privileged company information will be safe and sound from prying eyes.

Technology has created a world that has made almost everything faster and easier. In doing so, it has also made people and businesses more vulnerable than ever. While there always will be a need for physical security presence, computer security continue to increase in importance each year.
