- TYR evidence platform
Evidence management that holds up
under cross-examination.
TYR is our digital evidence platform. It packages evidence, records every action in a tamper-evident audit trail, enforces chain of custody from collection to courtroom, and produces court-ready documentation on demand.
Spreadsheets and shared drives are where chains of custody break.
Most organizations still track digital evidence with spreadsheets, shared folders and paper custody forms. Every gap in that record is something defence counsel can exploit, a regulator can question or an auditor can flag. TYR replaces it with a single platform that treats evidence integrity as the first requirement.
TYR was built by our digital forensics and incident response team, and it encodes the workflows, checks and documentation standards that court proceedings demand. It is not a forensics tool: it does not acquire or analyse evidence. It keeps the evidence your examiners, or ours, produce packaged, accounted for and ready for court.
It is delivered as a managed service, so there is nothing for you to host or maintain. On residency: we deploy to meet each client's data-residency requirements, including in-country where regulation requires it.
- Standard evidence intake and packaging, with metadata, notes and examiner details
- Hash recording at intake and verification at every access
- A tamper-evident audit trail of who touched what, when and why
- Chain-of-custody tracking with recorded, authenticated transfers
- Custody reports, evidence inventories and examiner declarations on demand
- A managed service with nothing to install or maintain
From intake to courtroom.
Intake
Guided workflows record each item as it arrives: source, acquisition notes, hashes and the examiner responsible.
Package
Items are sealed into evidence packages with full metadata, ready for legal review from the moment they are sealed.
Track custody
Every access and transfer is recorded in the audit trail, so the chain of custody is continuous and provable.
Present
Generate custody reports, inventories and declarations formatted for court whenever counsel needs them.

What buyers ask.
Is TYR a forensics tool?
No. TYR packages evidence and maintains its audit trail and chain of custody. Acquiring and analysing evidence is forensics, which our Bifrost examiners do.
We already track custody on paper forms.
Paper forms depend on every signature being collected and every form surviving. TYR records each action as it happens, so there are no missed entries for opposing counsel to find.
Where is our evidence held?
We deploy to meet each client's data-residency requirements, including in-country where regulation requires it.
Can we use TYR with evidence from other examiners?
Yes. TYR manages evidence regardless of who acquired it, as long as it is brought in through the intake workflow.
