With law enforcement-trained investigators and advanced forensic tools, we collect admissible evidence for court proceedings. Clients benefit from our expertise in working with prosecutors and defense attorneys to build strong cases.

Using Psychological Stress Evaluator (PSE) technology, our lie detection service analyzes vocal stress patterns without physical sensors. This non-invasive method works across languages and media formats, offering reliable results for marital infidelity, employment screening, and criminal investigations while maintaining subject comfort.

We develop customized protection plans for high-profile individuals and corporations, combining physical security measures with digital threat monitoring to prevent workplace violence and stalking incidents.
