Grey market brand protection is about genuine goods sold outside the authorised network, plus listings that undercut territory, price, and retailer trust. Bridge treats diversion as an investigation, not only as a listing takedown.
Grey market product is usually authentic. The harm is leakage: unauthorised sellers, parallel import, and price erosion that trains customers to ignore the official channel. It often sits next to counterfeit in the same wholesale networks.
We map who is selling, where the stock entered the open market, and which accounts restock after a notice. Takedowns close the storefront. Investigations follow the wholesaler, so the next listing is harder to stand up.
A platform can score a listing as unauthorised. It rarely reconstructs the leak: which distributor, which free-trade zone, which repeat seller behind new accounts. Grey market work that stops at the SKU does not change the channel.
