Investigations and technical countermeasures, led by a former FBI Supervisory Special Agent.

Organizations that have trusted Delta 7 with investigative, forensic and security matters
Engagements are confidential; no endorsement is implied.
The firm
Federal-agency methodology, applied to private matters.
Delta 7 was founded by Emmanuel Ladsous after a 24-year FBI career as a Supervisory Special Agent. The firm's examiners and investigators are former FBI personnel, including operational technology specialists, and technical operators from the intelligence community.
Our work is deliberately focused: fraud investigations and fact-finding that hold up in litigation, forensic examination of devices and vehicles, the detection of surveillance equipment used against businesses and individuals, and the design of the electronic security that keeps them protected. Drones are the newest addition to that threat picture, and our Drone Intrusion Investigations service answers it. Every engagement is handled directly by senior personnel and closes with a formal investigative report.
