Immutable audit logging for fintech platforms. Meet SOX, PCI DSS, and SOC 2 requirements with SHA-256 hash chains and Merkle tree proofs that satisfy financial regulators.
Fintech companies operate under some of the most stringent regulatory oversight in the software industry. Payment processors must comply with PCI DSS. Lending platforms face SOX and state lending regulations. Investment platforms answer to SEC and FINRA. Across all of these, audit logging is not optional. Financial regulators expect detailed, tamper-proof records of every transaction, access event, and configuration change. AuditKit provides the cryptographic audit trail infrastructure that fintech companies need to satisfy regulators, pass audits, and close enterprise deals.
PCI DSS v4.0 Requirement 10 (logging and monitoring)
SOX Section 302/404 (internal controls over financial reporting)
SOC 2 Type II (Trust Services Criteria)
DORA (for EU financial services)
State money transmitter licensing requirements
SEC/FINRA recordkeeping rules (for investment platforms)
BSA/AML transaction monitoring requirements
| Event | Description |
|---|---|
transaction.created | New financial transaction initiated |
transaction.approved | Transaction approved by authorized user |
account.balance_changed | Account balance modification |
kyc.verified | KYC identity verification completed |
kyc.failed | KYC verification failed or flagged |
payout.initiated | Payout or withdrawal initiated |
limit.changed | Transaction or account limit modified |
beneficiary.added | New payment beneficiary added |
suspicious_activity.flagged | Activity flagged for AML review |
Every financial transaction must be traceable from initiation to settlement, with a complete audit trail of approvals, modifications, and status changes.
Financial regulators require that audit records cannot be altered retroactively. PCI DSS 10.5 and SOX Section 802 both mandate tamper protection for audit trails.
BSA/AML regulations require real-time transaction monitoring for suspicious activity. SIEM integration enables automated detection and alerting.
Financial records must be retained for 5-7 years depending on the regulation. SOX requires 7 years, PCI DSS requires 1 year, and DORA requires 5 years.
SHA-256 hash chains and Merkle tree proofs provide mathematical proof that your fintech audit records have not been altered. This level of integrity assurance is increasingly expected by regulators and auditors.
AuditKit enforces strict tenant isolation at the infrastructure level. Your customers' audit data is logically separated, satisfying data segregation requirements common in fintech compliance frameworks.
Stream audit events to your existing SIEM for real-time monitoring and alerting. AuditKit integrates with Splunk, Datadog, Elastic, and other platforms commonly used in fintech security operations.
AuditKit is open source, so your security team and auditors can inspect the code. This transparency is particularly valued in fintech where trust and verifiability are paramount.
Fintech companies need comprehensive logging of financial transactions, user authentication, KYC/AML activities, permission changes, and system access. Logs must be tamper-proof (PCI DSS 10.5), retained for 5-7 years (SOX/DORA), and available for real-time monitoring (BSA/AML). AuditKit provides all of these capabilities with SHA-256 hash chains and Merkle tree proofs.
AuditKit provides tamper-proof audit trails that satisfy PCI DSS Requirement 10, SOX Section 404 internal controls, and SOC 2 monitoring requirements. The built-in React viewer gives auditors a clear interface to review evidence, and Merkle tree proofs allow mathematical verification of log integrity.
