NEW ISO/IEC 42001 evidence pack, now exportable

Know what your AI agent did when it matters.

Arkna turns fragmented model, tool, data and human activity into a reviewable record of an AI agent run, so your teams can reconstruct what happened, prove it, and account for it without starting from scattered logs.

01The problem

When an autonomous agent makes a decision, can you account for it?

AI agents are becoming operational across enterprises, approving, denying, scheduling, refunding, escalating. But when something goes wrong, most teams can't replay what happened, prove it, or explain it to a board or a regulator. You find out the agent failed when a customer complains, or when someone with subpoena power asks.

73%
of enterprises can't replay an agent decision after the fact.

ArknaRecorder

Captures what your agents did, without seeing who.

Reads what your stack already emits. Redacts personal data on the wire. Hash-chains every event so the record can't be edited after the fact.

03How it works

From agent action to verifiable evidence, in one chain.

STEP 01

Observe

Read what your agents already emit. Drop-in observer for OpenAI Agents, Anthropic, LangGraph, custom stacks.

STEP 02

Redact

Strip personal data on the wire. The record proves what happened without exposing who.

STEP 03

Seal

Hash-chain end to end. A single altered byte breaks the chain visibly. Tamper-evidence by construction.

STEP 04

Account

Replay any decision, verify the chain in the browser, export the regulator pack. Evidence on demand.

04For regulated industries

Where agents make decisions that have to be defended.

Financial services

Prove every credit, refund, and KYC decision your agents made.
