Why now is the time to switch
- Legacy consent tools like OneTrust are outdated: Originally built to meet 2018 GDPR deadlines, many tools are now inflexible, hard to configure, and no longer meet user experience needs.
- Disconnected modules cause friction: OneTrust has built an expansive privacy platform from a mixture of homegrown tech and acquisitions, which means they don’t speak to each other and lead to disconnected data.
- One-size-fits-all privacy doesn’t work: Evolving laws demand tailored consent strategies; generic approaches risk non-compliance and limit data value.
- Evolving technology: With cookies phasing out and AI-driven tracking on the rise, businesses need adaptable platforms that go beyond cookie-based compliance.
