About Us


ETS Intelligence is one of the leading Private Detective and Security Agencies in the Unites States.
We specialize in complex and high-tech investigations performed by experienced investigators using the latest in Cell Phone and Computer Forensics technology and methodologies. In conjunction with traditional investigative methods such as intelligence gathering and surveillance, detectives answer difficult questions that solve difficult cases. We are also experienced in depositions and live court appearances having testified as expert witnesses in many areas.


We can provide uniformed and/or plain clothes officers operating in an armed or unarmed capacity depending on the environment and your preferences. We employ both sworn law enforcement officers working off-duty and civilian security professionals. All of our officers are well trained, neatly groomed, and come from highly technical and disciplined backgrounds. We can handle both permanent and temporary assignments.


Our direct, secured, digital connection to the Illinois State Police - Bureau of Identification provides real-time electronic fingerprint submissions to Illinois State Police and FBI as required by law for many professions such as nurses, teachers, bank tellers and any other reason fingerprinting is necessary. ETS can fingerprint employees and contractors on-site or at our offices, whichever is more convenient for your institution or company.
