Evidence that survives cross-examination.
Chain-of-custody protocols, on-scene digital capture, and evidence integrity verification, for legal proceedings, regulatory investigations, and incident response.
Unverifiable evidence loses cases.
Every piece of digital evidence must demonstrate an unbroken chain of custody from capture to presentation. We establish and document this chain using cryptographic methods that produce independently verifiable evidence packages, not assertions.
Evidence captured and sealed at the scene.
When time-sensitive evidence must be collected at a physical location (a mine site, a port of entry, a crime scene), our team deploys with tooling to capture and cryptographically seal digital evidence in place. The hash is established before the device leaves the scene.
What can still be proven about existing records.
If records were captured outside a formal chain-of-custody protocol, we assess what integrity can still be established and document exactly what can and cannot be proven about their provenance. A clear-eyed assessment is more defensible than an overstated one.
Expert witness under technical cross-examination.
Our forensics team provides declarations and testimony for proceedings where digital evidence is in dispute, explaining cryptographic integrity methods in plain language that holds up against opposing counsel with technical expertise.
Capture works where signal doesn't.
Crime scenes, remote sites, and disaster response zones are often exactly where connectivity is denied, disrupted, intermittent, or limited (DDIL). Demia's capture hardware seals evidence on-site and syncs the record once a link is available. The chain of custody never waits on a signal.
