Best audit logging tools for compliance (2026)

Part of WorkOS's broader enterprise-readiness platform, alongside SSO and SCIM. Priced around $99/mo per 1M events plus roughly $125/mo per SIEM connection, WorkOS Audit Logs is built to capture and forward structured events, but doesn't publish a tamper-evidence mechanism, such as a hash chain, for the log itself.

Best for: Teams already using WorkOS for SSO and SCIM who want audit logs as one more piece of the same enterprise-readiness bundle, and don't need cryptographic tamper-evidence specifically.

Logs activity inside the Datadog platform itself, not your own application's events. Useful for tracking changes to your observability stack, but not a substitute for logging your product's user and system activity.

Best for: Teams that want visibility into who changed what inside Datadog, alongside their existing Datadog observability setup.

Logs AWS API activity across your account, with SHA-256 hashed and RSA-signed hourly digest files as a real, batch-level integrity mechanism. Priced per event delivered, $2.00 per 100k management events and $0.10 per 100k data events at AWS's published rates. Doesn't see events inside your own application.

Best for: Teams that need a record of AWS account activity itself, as a complement to, not a replacement for, an application-level audit log.

An open-source audit log project with some built-in integrity tooling, described as provable digest algorithms. Effectively unmaintained since BoxyHQ's acquisition by Ory in May 2025, with no new tagged release in roughly the two years since.

Best for: Teams comfortable self-hosting and maintaining an unmaintained open-source project themselves, or forking it, rather than relying on active upstream development.

These platforms automate evidence collection and control monitoring across your whole compliance program, but they consume audit log evidence from elsewhere rather than generating tamper-evident logs themselves. AuditRails' evidence bundles are built to plug into this kind of workflow, not compete with it.

Best for: Teams that already have, or are buying, a compliance automation platform and need a source of tamper-evident audit log evidence to feed into it.

What's the difference between a logging tool and an audit logging tool?

General logging tools, such as Datadog or CloudTrail, are built for observability, debugging, and operational visibility. Audit logging tools like AuditRails are built specifically for compliance evidence, which means tamper-evidence, framework-specific retention, and evidence a named auditor will accept are first-class requirements, not afterthoughts.

Do I need a dedicated audit logging tool if I already use a compliance automation platform like Vanta or Drata?

Usually yes. Compliance automation platforms monitor and collect evidence about your controls, but most don't generate tamper-evident audit logs themselves; they need a source for that evidence. AuditRails' evidence bundles are built to feed directly into that kind of workflow.

Is open-source audit logging, like Retraced, a safe bet?

It depends on whether the project is actively maintained. Retraced, for example, has had no new tagged release in roughly two years and has been effectively unmaintained since BoxyHQ's acquisition by Ory in May 2025. An unmaintained dependency in your compliance evidence chain is a real risk to weigh against the appeal of self-hosting.

What should a small team with one compliance framework use?

If it's just one framework, SOC 2 is the most common starting point, a flat-rate, single-framework plan is usually the most cost-effective path, letting you skip building tamper-evidence and evidence-bundling from scratch. AuditRails' Starter Trails plan is built for exactly this case.
