Immutable Audit Trail
Every agent action, logged in real time and queryable. Your compliance evidence, always ready.
Prefactor captures an immutable record of every agent action, span, policy decision, approval event, and quality or risk signal as it happens. When regulators or auditors ask how your agents are evaluated and controlled, the answer is a live system with searchable, exportable evidence.
Every agent run becomes an instance, and every step inside it — an LLM call, a tool invocation, a message — is recorded as a span with its input, output, duration, and outcome. Instances are immutable once written, giving reviewers a real-time, queryable record of exactly what every agent did.
What the audit trail captures
Every agent action, span, policy evaluation, enforcement decision, and approval event is recorded with full context — which agent, which policy or quality signal triggered the event, what decision was made, and when — the moment it happens. Records are tamper-evident, so an entry can't be quietly edited after the fact; the trail a regulator or an internal investigation sees is the same one Prefactor generated at the time.
Because every event links back to the registered agent that produced it, an auditor can trace a single production incident all the way from the triggering action back to the policy or quality signal that flagged it.
Querying and searching
The audit trail is full-text searchable and filterable by agent, team, time range, action type, policy, or enforcement decision, so investigating an incident means searching for what happened rather than scrolling through raw logs. The same search interface generates compliance reports on demand — a filtered view across a time range and a set of agents, ready to export.
Compliance and export
Exports are available as PDF, CSV, or JSON, and integrate with the SIEM and GRC tools a security or compliance team already uses, so audit evidence doesn't require a separate manual process to leave Prefactor. The trail maps to the specific compliance frameworks Prefactor supports — EU AI Act, GDPR, HIPAA, SOC 2, ISO 27001, ISO 42001, NIST AI RMF, and OWASP LLM Top 10 — with per-framework guidance at /compliance covering exactly which records satisfy which provisions.
