Use Case

Compliance and audit

Immutable audit trails for regulated industries.

The auditor arrives.

They ask for proof of every transaction.

Your team digs through logs.

Some records are missing.

Others were overwritten.

The audit stalls for weeks.

npayload records everything in a tamper proof chain.

Auditors get what they need instantly.

See how it flows

Tamper proof records

Every event is recorded in a hash chain. Altering any entry breaks the chain and is immediately detectable.

Immutable Audit Chain
#1042order.createda3f8...c21d
#1043payment.captured7e2b...9f4a
#1044inventory.reservedb91c...2e7f
#1045shipment.createdd4a7...8b3c
Every entry chained. Tamper proof.

Compliance frameworks

SOC 2 Type II, GDPR, HIPAA, and ISO 27001 controls mapped and continuously verified.

Data residency controls

Data stays in the region your regulators require. Cross border transfers require explicit consent.

Privacy Modes
Standard
Metadata + payload visible
Hybrid
Metadata visible, payload encrypted
Zero Knowledge
Everything encrypted. Even npayload cannot read it.

Retention policies

Up to six years of audit trail retention on enterprise plans. Configurable per channel.

How it works

1

Events are recorded automatically

Every message, delivery, and agreement creates an immutable audit entry.

2

Hash chains prevent tampering

Each entry references the previous one. Altering any record breaks the chain.

3

Export for your auditors

SOC 2, GDPR, and HIPAA controls are mapped. Audit reports are always ready.

Compliance and Audit Infrastructure: Before and After

Without npayload

  • Preparing for an audit means weeks of aggregating logs from dozens of systems
  • No tamper evidence on logs means auditors question the integrity of your records
  • Tracking data flows across organizational boundaries is nearly impossible
  • Compliance requirements change and your infrastructure has no way to enforce the new rules
  • Different systems log in different formats, making correlation a manual process

With npayload

  • Export complete audit trails for any time range in minutes, not weeks
  • Hash chain integrity proves logs have not been tampered with since creation
  • Every cross organization data flow is logged with sender, receiver, consent, and timestamps
  • Policy enforcement is built into the messaging layer, not bolted on after the fact
  • Unified event format across all systems with W3C distributed tracing

Frequently asked questions

How does hash chain integrity work?+
Every audit entry includes a cryptographic hash of the previous entry. This creates an unbroken chain where any modification to a historical entry breaks the chain and is immediately detectable. This is the same principle that makes blockchain ledgers tamper evident.
Which compliance frameworks does npayload support?+
npayload's architecture supports SOC 2, GDPR, HIPAA, and PCI DSS requirements. The immutable audit trail, encryption options, consent management, and data residency controls address the common requirements across these frameworks.
Can we stream audit events to our existing SIEM?+
Yes. npayload provides native audit streaming that sends events to your SIEM in real time. Supported formats include standard syslog and JSON. No batch export or custom integration required.
How long are audit logs retained?+
Retention policies are configurable per channel and per organization. You set the retention period that matches your regulatory requirements. Logs can also be archived to cold storage for long term preservation.
