Why teams choose AuditKit over Splunk

Purpose-built for compliance

AuditKit is designed specifically for compliance-grade audit logging. Splunk is a general-purpose SIEM that can be configured for auditing but requires significant setup and expertise.

Cryptographic integrity

AuditKit provides SHA-256 hash chains and Merkle tree proofs. Splunk stores logs but cannot cryptographically prove they have not been altered.

Predictable pricing

AuditKit starts at $99/mo with predictable pricing. Splunk charges based on data ingestion volume, which can lead to unexpected costs as your audit log volume grows.
