Service areas / tri-state region
Digital evidence and cyber response across the tri-state region
New York, New Jersey, and Connecticut coverage for expert work, evidence preservation, active cyber response, security testing, and OT and SCADA systems.
Choose the state or regional page that matches the evidence, system, deadline, and operating conditions.
The evidence in one matter can sit in several places: a laptop at home, a company mailbox, a cloud tenant, a data center, an industrial site, and an administrator in another state. GDF coordinates those sources under one scope and assigns remote, on-site, or laboratory methods according to access, condition, volume, custody, and operating risk.
Service area does not change the method
Each assignment begins with authority, the question to be answered, the systems involved, and any deadline or preservation risk. Evidence handling records the acquisition method, operator, date and time, source condition, verification details, and custody transfers. Cyber and OT testing remains within written rules and approved operating limits.
Confirm on-site logistics during intake
Remote work can begin quickly when the platform and authorization support it. Physical damage, specialized acquisition, contested custody, data volume, or plant restrictions may require on-site or laboratory handling. GDF confirms availability and logistics before the scope is accepted and does not use a service-area page to imply an unverified office.
