OneTrust is one of the largest GRC platforms in the world, with deep roots in GDPR and data privacy compliance now expanding into AI governance. Its breadth is genuine — AI inventory, governance workflows, and recently announced real-time monitoring capabilities. The limitation is equally genuine: AI governance in OneTrust is a module added to a general-purpose GRC platform, not a purpose-built execution-layer solution. Difinity was designed from day one to sit in the AI request path — intercepting, enforcing, redacting, and routing at the moment AI calls are made.
OneTrust and Difinity share some surface-level feature descriptions but operate very differently in practice. OneTrust is a broad GRC platform where AI governance is one module among many. Difinity is a purpose-built AI governance platform where the API gateway, policy engine, and compliance tooling were designed to work together as a single system.

OneTrust has earned its position as a leading GRC platform over many years. Its depth in data privacy, regulatory compliance, and organisational risk management is substantial — and for organisations that want AI governance integrated into a broader GRC programme they already run on OneTrust, there is genuine value in staying on one platform.
OneTrust was built on deep GDPR expertise and has extended that privacy-by-design thinking into AI governance. For organisations where AI governance intersects heavily with data subject rights, consent management, and privacy impact assessments, OneTrust brings genuine depth.
If your organisation already uses OneTrust for privacy, risk, or compliance management, its AI governance module connects to those existing workflows, risk registers, and reporting structures. Consolidating governance on one platform has genuine operational benefits.
OneTrust provides structured AI system inventory capabilities with governance workflows, risk assessment questionnaires, and stakeholder accountability tracking. For large enterprises managing hundreds of AI systems across multiple business units, this organisational depth is valuable.
OneTrust governs your AI programme. Difinity governs your AI requests. The difference is the execution layer: OneTrust tracks what your AI systems are supposed to do; Difinity controls what they actually do, at the moment each request is made. For organisations where regulatory exposure is created by live AI traffic — not governance documentation gaps — the distinction is fundamental.
Difinity Flow is a live API gateway designed exclusively to govern AI requests. Every call to every provider passes through it, is evaluated against active policies, and is either approved, blocked, redacted, rerouted, or escalated — before reaching any model. OneTrust added real-time AI monitoring capabilities in March 2026, but its core architecture remains a GRC platform, not a purpose-built AI gateway.
Purpose-built AI gateway: designed from day one for runtime enforcementDifinity detects and redacts PII — names, email addresses, national IDs, financial data, health records, custom patterns — before forwarding requests to OpenAI, Anthropic, or any other provider. The original context is restored in the response. OneTrust's data privacy heritage is strong, but its current AI governance module does not perform request-level PII redaction in the AI call path.
Pre-model redaction: names · emails · IDs · financial · health · custom patternsDifinity connects via a single API endpoint change and deploys in under 14 days without code modifications. OneTrust implementations are typically multi-month professional services engagements due to the platform's breadth and configuration requirements. For organisations facing near-term regulatory deadlines — such as the August 2026 EU AI Act high-risk enforcement date — implementation speed matters.
Time to live: under 14 days · no code changes · single API endpointOneTrust is known for complex, negotiated enterprise pricing where AI governance is bundled with modules your organisation may not need. Difinity is purpose-built for AI governance with modular, transparent pricing — you pay for what you use, without funding a broader GRC platform you may already have.

For organisations already running OneTrust, Difinity can complement rather than replace it: use OneTrust for organisational GRC and data privacy workflows, and use Difinity's gateway to enforce AI-specific controls at the execution layer. The two platforms solve different problems, and having both is not redundant — it is a complete governance stack.
OneTrust governs your AI programme. Difinity governs your AI requests — in real time, before every model call. Deploy in under 14 days alongside your existing GRC tools, with no code changes required.
