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.
AuditKit provides SHA-256 hash chains and Merkle tree proofs. Splunk stores logs but cannot cryptographically prove they have not been altered.
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.
Industry-leading SIEM with advanced search and analytics
Handles massive data volumes across all log types
Machine learning and anomaly detection
Huge ecosystem of apps and integrations
Strong brand recognition in enterprise security
Extremely expensive at scale (data volume pricing)
Not purpose-built for compliance audit trails
No cryptographic log integrity
Complex to configure for audit compliance use cases
Steep learning curve (SPL query language)
No built-in tenant isolation for SaaS audit logging
Use AuditKit if you need compliance-grade audit trails with cryptographic integrity and predictable pricing. Use Splunk if you need a full SIEM with advanced analytics, machine learning, and log aggregation across all data sources. Many organizations use both: AuditKit for tamper-proof audit logging and Splunk for broader security analytics, with AuditKit streaming events to Splunk.
AuditKit is not a Splunk replacement. AuditKit is purpose-built for compliance audit trails, while Splunk is a general-purpose SIEM/observability platform. AuditKit streams to Splunk via SIEM integration, so they work well together.
