Frequently asked about Amazon brand monitoring for private label.
Amazon brand monitoring means watching your own listings for anything that costs you sales or puts your brand at risk: new sellers on your ASINs, a lost or suppressed Buy Box, search suppression, changes to your title, images or bullets, FBA fee changes and account health. SentryKit does this in real time for every ASIN in your Seller Central account and alerts you with what changed and who changed it.
Brand protection software usually means enforcement: takedown requests, counterfeit claims and IP reports, often alongside Amazon's Brand Registry, Project Zero and Transparency. Brand monitoring is the early warning that tells you something needs enforcing. SentryKit is a monitoring tool. It finds the unauthorized seller or the content change and gives you the evidence, and you take action through Amazon.
No. SentryKit alerts you the moment an unauthorized seller joins your listing, with their seller ID, storefront, feedback, price and fulfilment, and links you to the offer list and to Amazon. Removing them happens through Amazon, usually with a Brand Registry Report a Violation.
Start with hijacker alerts, Buy Box alerts, search suppression and content change alerts, because those hit sales the fastest. Add FBA fee change and account health alerts to protect margin and keep your account in good standing. All of them are included on every plan, along with the rest of SentryKit's 50+ signals.
22 Amazon marketplaces, including the United States, Canada, Mexico, the United Kingdom, Germany, France, Italy, Spain, Japan and Australia. Prices in alerts are shown in the marketplace's local currency, and you can connect several marketplaces and storefronts under one account.
By email, Slack, Microsoft Teams, ClickUp, webhooks or the REST API. You can route alerts per storefront or per brand, so each one goes to the person who handles it.
