The Problem

Every enterprise customer asks 'do you have audit logs?' during security reviews. Building audit logging takes 2–4 months of engineering time. Poor audit logs fail SOC 2 audits.

The Solution

Drop-in audit logging API that captures who did what, when, and from where — with immutable storage, search, export, and retention policies ready for SOC 2 and HIPAA compliance.

Target Audience

Engineering teams at SaaS companies that need to add audit logging for SOC 2, HIPAA, or regulatory compliance without building from scratch

Key Features

1
REST API for logging any event (actor, action, target, metadata)
2
Immutable, tamper-proof log storage with cryptographic verification
3
Full-text search with filters by actor, action, date range
4
SIEM export (Splunk, Datadog) for security teams
5

Competitive Landscape

WorkOS Audit Logs

Audit logging as part of WorkOS enterprise features. Good but tied to WorkOS ecosystem

Replicated Audit Log

Audit logging for Kubernetes apps. Narrow focus on containerized deployments

Panther

Cloud SIEM with log analysis. Enterprise security tool, not developer-first audit logging

Custom built

Most companies build in-house. Takes 2–4 months, ongoing maintenance burden
