Mystery Shopping & Performance Audits

Mystery Shopping, aka Customer Service Auditing or Integrity Shopping is a valuable business tool for monitoring customer service, employee performance, honesty, adherence to company policy, as well as, an aid in loss prevention. With today's social networks, one bad experience (customer service, security, meal, rental, repair, etc) can literally cost you hundreds of prospective clients. One rude or dishonest employee can cost you thousands of dollars in revenue.

Video Mystery Shopping records the interaction with your staff and can be used not only as a teaching tool, but also to reward good customer service and to spot problems with safety, sanitation, building maintenance and security.

This type of service is beyond the scope of traditional shopping services and should only be done by a Licensed Private Investigation agency and only with the informed consent of your employees that they may be subject to videotaping and/or recording while on your premises. Nevada for example, mandates that only licensed private investigators or their registered employees, can do mystery shopping of any kind. The biggest advantage to using a P.I. firm is professionalism. You are guaranteed to get an agent that is impartial and accustomed to paying attention to fine detail.

Some businessses that use this type service are Banks, Department Stores, Convenience Stores, Security Contractors, Hotels, Restaurants, Car Dealers, Car Rental Agencies, Personal Care Facilites, Apartment Complexes, New Home Builders, Fitness Centers, Health Services, Automotive Repair Shops, Bars & Nightclubs, Entertainment Venues, Sports Facilities...virtually anywhere that involves interaction with the pubilc and/or handling of cash by employees.


Physical Security Assessments

At STOPP we are concerned with every aspect of physical security. We start by offering professional Physical Security Assessments, where we work with your management team to assess and make recommendations on if you need to, and how to improve the security of your facility. We review your security procedures and discretely observe the operations of your security systems, in-house security personnel, contract security workers and barriers (both electronic and physical) to sensitive areas. We specifically look for weak spots that could easily allow unauthorized persons to gain entry, present a danger to your staff and cause damage to your facility.

Security Officers

If you are ready to make a change from your current security contractor, you will find that our Security Officers are elite professionals skilled in handling your security needs in a calm, polite and professional manner. We offer armed and unarmed, uniformed and plainclothes security services for Corporate Offices, Hospitals, Schools, Construction Sites, Oil & Gas Fields, Retail, Manufacturing, Hotels, Special Events, Banks, etc. At STOPP Security we strive to provide you with the best security services available.

What makes us different than the rest?

We pay our officers higher wages while charging rates competetive with the other companies, and offer the most comprehensive physical training available anywhere! We do this because:

We want to attract quality, experienced people

We want to hire people who will care about the quality of their work and the safety of your staff, property and your person.

We only want committed officers who want to continue their training, move up in the company and be proud of the service they provide and the company they represent.

We strive to maximize officer retention to prevent interruptions in service and scheduling problems. Our people should be considered a member of your team.

Our goal is to provide customized private security to match your needs. We’ll sit down with you for as long as necessary and create a security detail to match your specific situation. We are your first line of defense, trained to handle the in-house side of an emergency and provide security for your establishment and staff. If all you want is a “Visual Deterrent” guard at the lowest possible cost, we can provide that for you too, but we will never skimp on staff, training or service just to be the lowest bidder. Our goal is not to be the biggest, but to be the BEST!

Bodyguards and Executive Protection

All Special Officers (Bodyguards) are carefully screened professionals who have been hand picked and extensively trained in-house to provide the very best in armed and unarmed protection.


STOPP's exclusive CCT (Control & Compliance Tactics) Training was designed and certified by internationally recognized self-defense experts, specifically for the professional Security Officer or Executive Protection Officer. It features the most effective unarmed techniques ever developed, for defense and control of aggressive subjects.

Not only is this training part of STOPP's ongoing training curriculum, but we also offer it to any Security Officer, Law Enforcement Officer, Emergency Responder or any company who wants their officers to enhance their present skills, have better control of potentially dangerous situations, and be less likely to end up using excessive force.
