Online brand protection software built to stop grey market losses
GreyScout is the end-to-end online brand protection platform and solution that detects unverified sellers, verifies who they are, and enforces against them, with a 95%+ enforcement success rate and 14× average client ROI. Protect your customers and brand, online.
Protecting some of the world’s biggest brands
Online brand protection means detecting grey market listings, IP infringement, and unverified 3P sellers across marketplaces — and enforcing against them permanently. For most consumer brands the biggest threat isn’t counterfeits: it’s genuine product diverted through channels you don’t control. GreyScout is built to end exactly that.
How GreyScout works:
Detect, Verify, Enforce
Our platform leverages the latest in automation technology to monitor for and provide full visibility of intellectual property infringements online, no matter where they are.
Detect & Monitor
Always-on monitoring continuously scans online marketplaces and automatically flags potential IP infringements and unverified sellers for review by your product and enforcement teams. Continuous coverage, not periodic sampling.
Verify & Authenticate
Proprietary, fully customisable seller verification identifies who is behind a listing and authenticates listed products across marketplaces, quickly and at scale. Verification is what separates a defensible enforcement case from a guess. GreyScout has verified 156000+ third party sellers so far.
Enforce & Report
One-click enforcement removes infringing 3P listings for good, with full audit trails and reporting your legal and channel teams can stand behind. 95%+ of GreyScout enforcement actions succeed.

What online brand protection does for your business
Revenue Protection
Every unverified seller on your listings is taking margin and Buy Box share from you and from the authorised channel you built. GreyScout customers see an average 14× return on their investment in the platform.
Channel Trust
Your distributors and authorised resellers watch your listings too. Visible, consistent enforcement protects the partner relationships your revenue depends on.
Customer safety and brand equity
Product sold outside your governed channel arrives without your quality, storage or safety guarantees. Removing those listings protects the customers who trust your name.
What our enforcement work looks like at scale in August 2026
These are aggregate figures from GreyScout’s own monitoring and enforcement operations, updated August 2026.
When you are growing your Amazon presence globally and moving into new platforms simultaneously, brand control cannot be an afterthought. FireAngel products protect people in their homes, and that only works if customers are buying genuine, verified product wherever we sell. GreyScout has made that assurance a default, and it is a capability we expect to lean on increasingly as our international footprint grows.

FAQs
Answers to the questions buyers ask us most.
What is online brand protection software?
Online brand protection software helps businesses detect, verify and act against unverified 3P sellers, counterfeits and IP infringement across online marketplaces. Effective platforms combine automated monitoring, seller verification and enforcement workflows, so brands can control distribution and act against infringers at scale. For the fundamentals behind the software, read our guide: what is brand protection.
Why is brand protection on eCommerce marketplaces important?
Amazon alone reports investing more than $1 billion annually and employing thousands of people to fight counterfeiting, fraud, and marketplace abuse. As marketplaces have become the default storefront for consumer brands, grey market activity and infringement by unverified 3P sellers have scaled with them — and brands that don’t monitor lose revenue, channel trust, and customer safety without ever seeing it happen.
What should I look for in an online brand protection solution?
Three things: automation at scale (continuous monitoring, not periodic sampling), verification capability (knowing who a seller actually is before you act), and enforcement that sticks (permanent removals with audit trails, not cease-and-desist correspondence).

What is grey market?
The grey market refers to genuine branded products sold through distribution channels the brand hasn’t approved. Grey market vendors may lack authorisation to sell those items at all, or to sell them in a specific country or region. Read more on the topic:

What are parallel imports?
A parallel import is the sale of a genuine product outside its brand’s approved distribution channels, typically across borders. Legality usually turns on national versus international exhaustion of IP rights. Read more on the topic:
How is GreyScout's online brand protection different from takedown-only services?
Most services detect and send notices. GreyScout verifies seller identity first, which is why 95%+ of our enforcement actions succeed and stay enforced. Detection tells you there’s a problem; verification and enforcement solve it.
We're losing revenue to unauthorized resellers across multiple marketplaces — can one platform stop this?
Yes. That’s the point of consolidating brand protection into a single platform rather than monitoring each marketplace separately. GreyScout provides continuous coverage across Amazon, eBay, Google Shopping and other major marketplaces from one dashboard, so a seller diverting product across three channels appears as one case, not three unconnected alerts.
How do I justify the ROI of a brand protection platform to my leadership?
Track revenue recovered through Buy Box ownership restored and listings removed, weighed against the platform’s cost. GreyScout customers see an average 14x return on their investment — driven by scale (automated monitoring vs. manual sampling) and by verification-first enforcement, which holds up rather than getting reversed.
What defines the best brand protection software for marketplaces in 2026?
The differentiator is no longer detection — most platforms can find listings. It’s what happens next. The strongest platforms verify seller identity before enforcing, which is what makes a removal permanent rather than a listing that reappears under a new seller name a week later. Look for continuous marketplace coverage, verification capability you can audit, enforcement outcomes reported with evidence, and reporting your legal and channel teams can act on.
What actually happens when GreyScout enforces against a listing?
Four steps:
1. monitoring flags the listing and it’s routed for review.
2. seller verification establishes who is behind it and whether the listed product is authentic — this becomes the evidence pack.
3. the case is filed through the relevant marketplace’s enforcement channel, with the evidence attached.
4. removal is confirmed and logged, and the seller stays on monitored watch in case they relist under a new identity. You see every step and its outcome in the platform.
