Evidence Management
Every artifact collected during an investigation is timestamped, hashed, and stored with provenance — ready for regulatory review, legal proceedings, or internal audit.
Investigations are only as defensible as their evidence. Nirvet captures every artifact with a cryptographic hash, a timestamp, and full provenance metadata, then preserves the chain of custody from collection to export. Legal hold, retention, and export packaging are first-class — so when someone asks how you know, you have the record to prove it.
Chain of custody
Who collected what, when, from where, and every hand-off since — recorded immutably alongside the artifact.
Integrity by hash
Each artifact is hashed on capture. Tampering is detectable; integrity is verifiable at any later point.
Export packages
Assemble a complete, self-describing evidence pack for auditors, regulators, or counsel — on demand.
Legal hold & retention
Place holds that survive routine retention, and enforce deletion schedules that are themselves auditable and atomic.
What you get
- Timestamped, hashed artifacts with provenance metadata
- Legal hold that overrides retention until released
- Retention-delete that is atomic and recorded
- Evidence tied to the incident, playbook run, and decisions that produced it
- Export aligned to regulatory and legal review needs
