Top Investigation Services Companies

A whistleblower alleges an executive is taking kickbacks, a lawyer needs to find a defendant's assets, an investor wants to know who really owns a target company. Investigation services handle these questions for businesses and their counsel: fraud and misconduct inquiries, background and due diligence checks, surveillance, asset searches, witness interviews and evidence collection that will hold up in court.

The investigation firms here include licensed private investigators, former law enforcement teams and global risk consultancies. Shortlist those that handle your type of case and jurisdiction, and check how they report findings for use in litigation or disciplinary action.
