Services
Asset Searches
Our asset search services identify hidden or undisclosed financial resources for legal and business purposes. Using covert, multi-jurisdictional techniques, we uncover bank accounts, real estate, and employment details to support litigation or debt recovery. Decades of experience ensure comprehensive results for attorneys and individuals navigating complex financial disputes.
Child Custody Surveillance
We provide time-stamped video evidence documenting child custody arrangements. Former law enforcement investigators use discreet surveillance to verify parental fitness and compliance with court orders. This critical documentation helps protect children's welfare and supports legal modifications to custody agreements.
Computer Forensics
Our digital forensics team recovers and analyzes electronic data from compromised devices. Using specialized software, we identify security breaches, recover deleted files, and trace cyber threats. This service protects businesses and individuals from data theft while providing court-admissible digital evidence.
Executive Protection
We design customized security solutions for high-risk individuals, combining physical protection with electronic countermeasures. Licensed bodyguards and threat assessment specialists create layered defense strategies against stalking, harassment, or targeted threats. Services include vulnerability audits and 24/7 protection coordination.
Fraud Investigations
Our team exposes insurance fraud and workers' compensation abuses through surveillance and undercover operations. Specialized techniques document fraudulent activities, saving businesses substantial losses. We provide evidence packages for legal proceedings and collaborate with district attorneys for prosecution referrals.
