AI Governance

EU AI Act — Preliminary Classification

Preliminary internal assessment indicates ONX currently operates outside EU AI Act high-risk classifications (Annex III). ONX provides commercial decision-support tools only — not employment, credit, law enforcement, or healthcare decisions.

AI providersAnthropic (Claude), OpenAI (GPT-4o)
Use of AIICP recommendations, signal scoring, deal risk indicators, summaries
Personal data in promptsNo — company-level context only
Model training on customer dataNo — contractually prohibited with all AI providers
Automated decisionsNone — human review required for all commercial actions
Confidence disclosureAI outputs surfaced as indicators, not deterministic facts
Prohibited uses policyDocumented — employment, credit, legal, healthcare decisions prohibited

Subprocessors

ONX uses a limited set of third-party subprocessors. Each is covered by a DPA and Standard Contractual Clauses (SCCs) where data is transferred outside the EEA. 30 days' notice is provided for new subprocessors.
