Proofpoint is highly likely to be cited by AI engines for evaluation-stage queries (e.g., “Proofpoint vs Mimecast” and “best email security”) because it has strong third-party review presence (G2/Capterra/TrustRadius) and first-party competitor comparison pages. The single highest-ROI fix is to strengthen structured data + crawlability for evaluation content (SoftwareApplication/FAQPage + ensure pricing/packaging pages are fully crawlable/SSR), so AI engines can cite Proofpoint directly for “pricing” and “vs” questions without relying on third parties.
