Welcome to Global Security and Investigative Services, a distinguished group of professional Texas-licensed private investigators and security personnel. Our team comprises experts in investigations and personal security, ensuring you receive top-notch services.

With strategically located offices in Houston, Dallas, Austin, and the Lower Rio Grande Valley, we cater to a wide range of private investigation and security services needs. Our areas of focus include but are not limited to:

  1. Handling cases of infidelity and cheating spouses
  2. Resolving domestic disputes and relations
  3. Assisting with family law matters
  4. Providing support in child custody and visitation issues
  5. Addressing various corporate concerns

With over two decades of investigative experience, we possess the skills and knowledge to do the job efficiently. Our team members have encountered numerous situations requiring a private investigator’s expertise, which enables us to empathize with your circumstances and offer immediate assistance.

We recognized the need for a different kind of agency that prioritizes personalized attention and a customized approach tailored to your specific requirements. Unlike companies that burden clients with unnecessary and expensive evidence-gathering processes, we aim to simplify the journey by focusing on your needs.

Global Security and Investigative Services is your ideal destination whether you need a private investigator or security services. Our commitment to providing peace of mind begins with a free consultation, during which we offer guidance and insight to help you make informed decisions.

For instance, we may recommend a trash pull in certain cases, which can be more effective and cost-efficient than extensive surveillance. Our experienced Austin private investigators can spend a few hours analyzing the results of a trash pull, potentially uncovering evidence of drug use or other illicit behavior that may otherwise go undetected.

Unlike some Houston private detective agencies prioritizing financial gain over client satisfaction, we genuinely care about delivering meaningful results. We will always recommend the appropriate level of service to achieve your objectives.

Occasionally, there may be rare instances where we cannot assist you. In such situations, we will only accept your money if we provide a solution. Instead, we will refer you to someone who can effectively address your needs.

At Global Security and Investigative Services, you can trust that you will receive individualized attention and a tailored plan from a specialist who understands the unique dynamics of your case. We do not believe in the one-size-fits-all approach often employed by retired law enforcement professionals who try to apply criminal evidence-gathering techniques to family law matters.

To resolve your situation, call us at 1-800-364-1883 or fill out our contact form to request a free and no-obligation consultation.

We understand that time is of the essence when you seek our services. Rest assured; we are here to help you devise a plan and take action promptly. Remember, we have your back every step of the way.
