Compare AuditKit and Elastic (ELK Stack) for audit logging. Elastic is a powerful search and analytics engine, while AuditKit provides purpose-built compliance audit trails with cryptographic integrity.
| Feature | AuditKit | Elastic (ELK Stack) |
|---|---|---|

| SHA-256 hash chain integrity | — | |
| Merkle tree proofs | — | |
| Tenant isolation | Manual | |

| Log aggregation | Audit events | All logs |
| Compliance reports | Manual |
AuditKit provides compliance-grade audit trails out of the box. Elastic requires significant configuration and custom development to achieve similar compliance capabilities.
AuditKit provides SHA-256 hash chains and Merkle tree proofs. Elastic stores data but has no built-in mechanism to prove logs have not been tampered with.
AuditKit is a managed service (or simple self-hosted deployment) purpose-built for audit logging. Running Elastic for audit compliance requires managing Elasticsearch clusters, configuring retention policies, and building custom compliance tooling.
Powerful search and analytics engine
Kibana visualization and dashboarding
Can be self-hosted (SSPL license)
Handles very large data volumes
Strong ecosystem (Logstash, Beats, etc.)
Not designed for compliance audit trails
No cryptographic log integrity
Significant operational overhead for self-hosting
Requires expertise to configure for audit compliance
License changed from Apache 2.0 to SSPL
No built-in tenant isolation
Use AuditKit for compliance-grade audit trails with cryptographic integrity and minimal operational overhead. Use Elastic if you need a general-purpose search and analytics engine for all types of log data. AuditKit can stream events to Elastic via SIEM integration for organizations that want both compliance-grade auditing and powerful search analytics.
You can store audit events in Elasticsearch, but you will need to build cryptographic integrity, tenant isolation, compliance reporting, and audit-specific query interfaces yourself. AuditKit provides all of these out of the box, saving months of engineering effort.
