About AuditRails
Making compliance-ready audit logging accessible to every software team.
Our mission
Every AI company in the EU now needs audit logging. The AI Act's Article 12 mandates automatic event recording for high-risk AI systems; Articles 14, 50, 72, and 73 add human oversight, transparency, post-market monitoring, and incident reporting on top. Most teams build this from scratch, spending months on infrastructure that is not their core product.
AuditRails exists to solve this problem once. We provide a drop-in SDK and API that gives any high-risk AI system cryptographically verifiable, tamper-evident audit logs with 10-year WORM retention. Five lines of code. Minutes to integrate. Audit-ready from day one.
Why we built AuditRails
We have been through AI Act conformity assessments, SOC 2 audits, and enterprise security questionnaires. Every time, the audit logging requirement was the same: show an immutable record of who did what and when, and prove it has not been tampered with. For high-risk AI systems, the bar is higher, Article 12 requires automatic event recording across the system's full lifetime.
Most teams duct-tape this together with application logs, database triggers, or a spreadsheet of events. It works until the auditor asks for proof of immutability. That is when you realize you need cryptographic guarantees, not just a database table.
AuditRails uses SHA-256 hash chaining, the same concept behind blockchain, to create a verifiable chain of custody for every event. Combined with WORM (write-once-read-many) storage, it creates an audit trail that is provably tamper-proof.
Our principles
Security is non-negotiable
We hash API keys, encrypt data in transit and at rest, enforce tenant isolation at every layer, and never log sensitive data. Security is not a feature, it is the foundation.
Immutability by default
Every log is hash-chained and stored in WORM storage. We cannot modify your audit logs even if we wanted to. That is the point.
Developer experience matters
Compliance tools do not have to be painful. Our SDKs are designed to be installed in minutes, not days. Five lines of code is all it takes.
Transparent pricing
No per-seat fees. No surprise overages. Three simple tiers based on your usage and compliance needs. 90-day free trial, no credit card required.
