OneTrust

OneTrust is the platform most GDPR programmes are eventually compared against, and its current positioning has shifted from pure privacy tooling toward what it calls AI governance: preventing data misuse across a tech stack so an organisation can "govern well and move fast." It has been named a Visionary in the 2026 Gartner Magic Quadrant for AI Governance Platforms, reflecting that repositioning.

Coverage spans consent and cookie management, data mapping, subject rights automation, vendor and third-party risk, and privacy programme management, making it the broadest platform in this category rather than a point solution. That breadth is also the trade-off worth knowing before shortlisting it: a competitor in this same category (Enzuzo) states directly on its own site that "OneTrust just raised its minimum to $10K/year," positioning itself as the alternative for teams that don't need enterprise-scale tooling. For a large, multi-entity organisation the breadth justifies the cost; for a smaller team it may not.
