Evidence You Can Trust. Answers You Can Act On
When your case depends on what’s inside a phone, computer, or online account, you need more than screenshots or assumptions. You need licensed digital forensic investigators who understand evidence handling, chain of custody, and courtroom standards.
At Global Defense Investigation (GDI), we recover, authenticate, and analyze data from mobile devices, computers, cloud accounts, and damaged media.
Our job is simple: deliver proof you can use in court, mediation, or legal negotiations.
With offices in Fairfax and Woodbridge, VA, GDI provides local support backed by nationwide capability through our investigative network.
