Platform capability
Tamper-Evident Audit & Assurance Evidence
Preserve service events, cryptographic context, retention policy, signed checkpoints, streaming, evidence packs, and replay-oriented verification boundaries.
Buyer outcome
Give engineering, security, auditors, and regulators a shared record that separates configured controls, observed events, generated reports, validation, and external assurance.
Source-backed · complete event coverage not verified
For Audit · Compliance · CISO · Platform operations
Evidence boundary
Audit ingestion, chaining, checkpoint signing, retention, streaming, reporting, and evidence-pack contracts exist in source. Complete service-event coverage, checkpoint publication, replay, and independent production verification remain NOT VERIFIED.
Capability map
What audit & evidence covers
Each item is a source-backed or deployment-bounded capability, not an implied certification or universal runtime guarantee.
Operating model
How the capability fits into an accountable workflow
01
Record
Accept an eligible event with tenant, actor, resource, operation, result, and cryptographic context.
02
Link and checkpoint
Extend the configured chain and create a signed checkpoint according to the implemented policy.
03
Retain and stream
Apply the tenant retention target and deliver eligible events to configured downstream systems.
04
Package and verify
Generate an evidence package while keeping report generation, signature validation, and external assurance as separate states.
Integration & assurance

Frequently asked questions
Audit & Evidence questions
Does generating an evidence pack prove compliance?
No. A report packages recorded observations and workflow state. Signature validity, evidence completeness, control effectiveness, legal applicability, certification, and regulator acceptance are distinct questions.
Is every QNSI operation proven to enter the audit chain?
No. The audit architecture and event contracts are source-backed, but complete production ingestion across every service and operation remains NOT VERIFIED unless a deployment-specific evidence set proves it.
Next step
Evaluate the capability against your actual environment
Start with the public evidence, then scope the exact services, integrations, custody, deployment, and assurance required. QNSI will not convert source presence into a production claim without evidence.
