PrivacyRadar vs TrustArc
TrustArc manages your program. PrivacyRadar watches your production.
TrustArc is a governance and consent suite built for compliance officers, with website monitoring as a periodic cookie-audit module. PrivacyRadar is an observability platform: it retests consent behavior, diffs your third-party surface, and preserves evidence on every scan.
Where TrustArc is strong
Deep assessment/certification practice and a long-standing consent (CMP) business trusted by legal teams.
Running both
Teams commonly keep TrustArc for assessments and CMP while PrivacyRadar monitors runtime behavior and alerts engineering the day something regresses.
Capability comparison
| Capability | PrivacyRadar | TrustArc |
|---|---|---|
| Consent behavior validation (Accept / Reject / Ignore / Revoke / GPC in real browsers) | Every scan runs five scenarios in isolated browser contexts and records what actually fires after Reject, after withdrawal, and under GPC — with screenshots. | Banner and cookie audits; rejection behavior is not exercised per deploy. |
| Privacy policy vs. observed behavior | Deterministic disclosure extraction diffed against observed vendors, session replay, and fingerprinting — drift becomes a dated event. | Policy management workflows; no per-scan behavior comparison. |
| Change-only alerting | Diff engine: new/resolved findings, risk deltas, consent regressions, vendor added/removed. No change, no email. | Periodic reports and dashboards. |
| Tamper-evident evidence | SHA-256 at collection, content-addressed storage, digest re-verified on download, Ed25519-signed PDF exports with offline verification manifests. | Exports and screenshots without a cryptographic chain of custody. |
| Engineering integration | Scoped API keys, HMAC-signed webhooks with retries and delivery logs, optional GitHub Action composite gate, findings with rule keys and playbooks. | Built for privacy-office workflows; engineering access is secondary. |
| Jurisdiction rule packs | 27 versioned packs (EU, Canada, 18 US states, COPPA, HIPAA web PHI, AI-adjacent transparency, AI Surface Art. 50 topics) — toggleable per organization; attribute-gated where required. | Regulatory content oriented to assessments and templates. |
Competitor descriptions reflect our understanding of publicly documented positioning and are the reframe we bring to evaluations — verify current capabilities directly with each vendor.
The bake-off that settles it: scan your own site.
