Every defense challenge to digital or physical evidence is ultimately an argument about a gap: a handoff not documented, an access not logged, a period unaccounted for. Demia closes those gaps continuously, not retroactively.

The problem
The gap is where prosecutions unravel.
Courts need the chain of custody accounted for. Where documentation is missing, the prosecution has to explain the gap. Records assembled after a challenge arrive too late.
What Demia does
Custody signed at capture, transfer and access.
Demia signs and hashes evidence at seizure, from live networks, scenes and labs. Integrations with evidence management, IoT lockers, RFID and property room systems log every physical handoff. Field hardware seals evidence at the scene, even with no signal.
Multi-agency work
Share across agencies without breaking custody.
Authorized partners access specific records without evidence leaving the lead agency's custody. Every review, download and export is logged.
When evidence is challenged
The timeline answers.
The custody record shows exactly when and where any break occurred: off-hours access, custodians with no case role, transit out of sequence. Court packages include methodology, hash values, timestamps, the full access log and examiner declarations.
Legal hold
A cryptographic receipt for every hold.
When a hold is triggered, Demia locks the relevant records and issues a signed receipt of exactly what was in scope and its state at lock time.
