Guardian National Security employs today’s most-effective private security tactics, from state-of-the-art surveillance equipment to exceptional guard services. Our guards have all been carefully selected by our management team and are required to continuously meet our high standards. We have a large team of licensed security guards who are skilled at staying vigilant, preventing criminal activity, discouraging unwanted behavior, enforcing rules, maintaining order, responding promptly to emergencies and documenting incidents. They can also be trusted to handle additional assigned post order duties, such as greeting guests, answering phones, keep truck logs and more. All guards must pass background checks, drug testing, participate in skills training on a regular basis and consistently meet the expectations of our clients. Every guard is monitored using an advanced time card system and a GPS enabled app system.

Guardian National Security: Adelanto's Best Choice for Private Security Services

Guardian National Security has worked hard to meet the unique needs of our clients in Adelanto (as well as nearby Helendale and Oro Grande), which is why we specialize in store security, parking lot security, hotel security, school security and event security. While many aspects of our services will remain consistent no matter the location or industry, there are some instances where experience can make a huge difference in the effectiveness of a security program. For example, when it comes to parking security, we know that it is extremely crucial to be aware of all the hidden or dimly lit areas in the parking lot and to either patrol these areas regularly or proactively position motion detectors or security cameras to monitor them. Additionally, we know how to make sure you get an excellent return on your investment. In the case of parking security, for example, we could have our guard provide safety escort services to your employees or patrons in the evening, block guest parking spots with cones when they need to be reserved, assist with lockouts and perhaps help clients who need to jump start their battery. Call today and let us show you how our private security services can benefit your residence, business community or event in Adelanto, Helendale, or other nearby area.
