SUPPLY CHAIN

Verify Every Link In The
Supply Chain

Programmatic supply chains route through more resellers than either side usually realizes, and every extra hop adds cost and risk.
DeepSee maps and verifies the path from publisher to buyer- matching ads.txt declarations against sellers.json, connecting
domains through shared identifiers and traffic relationships, and flagging unauthorized resale, so you know exactly who's
authorized to sell what, and who's really behind it.

Every hop is a risk and potential cost.

Ads.txt ↔ Sellers.json Verification

DeepSee cross-checks each declared seller against the corresponding sellers.json entry, reporting a line-level verifiable rate rather than a simple has-a-file / doesn't check. Partially unverifiable files are flagged as a transparency risk, catching the gap where "has ads.txt" still hides unauthorized paths.

Connected Through the Evidence

DeepSee.io links seemingly-independent domains through the fingerprints they share- common Google Publisher IDs, analytics tags, and traffic relationships, revealing when a long list of "diverse" sites is really one operation. It's the same connect-the-domains analysis that let us trace an entire laundering network back to a single beneficial owner, evidence you can see rather than ownership you have to take on faith.

Traffic You Can't Hide

A site can look clean on its own homepage while quietly loading traffic from, or sending it to MFA, piracy, and high-risk domains. DeepSee profiles each domain's inbound and outbound connections and scores the risk rate of the company it keeps.
