FORRESTER WAVE REPORT

The Foundation of AI Security Just Got Independent Validation.

Forrester named BigID a Leader in The Forrester Wave™: Sensitive Data Discovery And Classification Solutions, Q2 2026.

BigID is one of three Leaders out of ten evaluated, and received the highest possible scores in eleven criteria, including the capabilities every serious AI security program is built on.

You Can't Govern AI Without Knowing Your Data. Forrester Just Confirmed Who Does It Best.

AI security starts with a question most organizations can't fully answer: where is your sensitive data, who can reach it, and what happens when AI touches it?

Sensitive data discovery and classification is the answer layer. It's the infrastructure that makes AI governance, Zero Trust, DLP, and agentic access controls possible. Without it, you're enforcing policy on data you haven't fully seen.

Forrester evaluated ten of the most significant platforms in this space. BigID came out as a Leader, with the highest possible scores across the criteria that matter most for both data security programs and AI governance.

For AI governance

You cannot govern what AI touches without knowing what's sensitive and where it lives. Forrester found BigID covers "numerous use cases — from compliance and information governance to AI security and governance" — with the enrichment, context, and integration depth to make that coverage actionable, not just visible.

For board and regulatory accountability

When your board asks about data security posture — or a regulator does — "we have a platform Forrester scored at the top of the field" is a materially different answer than "we have tooling in place." Highest possible scores in secure-by-design commitments and integrations mean the posture you're reporting on is real.

For attack surface management

Sensitive data you haven't found is sensitive data you can't protect. "Impressive strengths in discovery across both cloud and on-premises data sources including mainframe" — Forrester's words — means the attack surface is mapped. The gaps that become breach vectors are the gaps in discovery. BigID closes them.

For what comes next

The highest possible scores in Innovation (25% weight) and Roadmap (20% weight) aren't retrospective. They're a forward-looking verdict on whether a platform will keep pace with the threat landscape. The "autonomous governance engine" vision is what AI-era security programs require — and Forrester found BigID is building it.

Built for the Organizations Where Data Security Cannot Fail

Forrester identified BigID as "a compelling choice for multinationals, large organizations, and government entities with complex data environments and localization requirements."

These are the organizations where a data breach isn't a news cycle — it's a regulatory action. Where AI governance isn't a roadmap item — it's a board-level mandate. Where petabyte-scale performance isn't a feature — it's a baseline requirement.

BigID Next is engineered for exactly those environments. And now there's independent third-party evidence to prove it.
