Anchor a verified record of the content context for each ad placement, confirming it appeared on brand-safe content as agreed with the publisher. Brands and their agencies gain independent evidence of where ads actually ran, beyond the platform's own reporting.
Turn platform-reported placement into an independently verifiable record of ad context.
01.
Read the content around the ad. The External Data Oracles module supplies a classification of the content each impression ran against, so placement context is captured rather than assumed.
02.
Anchor where each ad ran. The Provenance Notary module seals the content context and placement for every impression, creating a tamper-evident record independent of the platform.
03.
Encode the advertiser's line. Each campaign's acceptable content categories are encoded, so a placement is checked against the exact safety terms agreed with the publisher.
04.
Surface unsafe placements. When an impression runs against content outside the agreed categories, the contract flags it as a violation with anchored evidence rather than a complaint.
05.
Preserve the placement trail. The Audit Logs module records the context, rule, and outcome for every placement, giving brands and agencies a complete basis for post-campaign audit.
06.
Escape platform-only reporting. Brands query the anchored record to verify where ads appeared for themselves, replacing trust in the platform's after-the-fact report.
Follow a single ad placement from serving through content classification to anchored verification or violation flagging.

Cerulea decomposes brand-safety verification into modular contracts. Each layer ingests the placement, classifies the content, evaluates the rules, and anchors evidence without relying on the platform's own report.
Independent brand-safety verification is a horizontal capability. Here is how different actors in advertising put the placement record to work.
Gain independent evidence of the content context for every placement, verifying that ads ran on brand-safe content instead of trusting the platform's own after-the-fact report.
Key Asset Types
Prove agreed brand-safety terms were met with anchored placement records, defending inventory value and resolving safety disputes against tamper-evident context.
Key Asset Types
Audit where a campaign's ads actually appeared across platforms from one independent record, replacing fragmented platform reporting with a shared source of evidence.
Key Asset Types
Whether you are bridging a platform's ad-placement logs or wiring a content-classification provider into the feed, Cerulea routes both into one independent placement record.
For platforms on legacy ad systems. Placement events are translated into signed, classified on-chain records through the API gateway automatically.

Building an independent brand-safety verification chain with content classification, rule evaluation, and tamper-evident placement anchoring from scratch requires specialised engineers and long ad-tech integration cycles. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects brand-safety integration benchmarks. Wiring ad-placement logs, coding content classification and rule evaluation, and building tamper-evident evidence anchoring for an average network takes a baseline of 8 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your safety and placement rules into pre-audited WebAssembly binaries and provisions the placement evidence ledger instantly.
