As answered by people managing Sli.do and Katcher.
Katcher's answer:
Katcher finds fake stores copying your brand and backs every finding with evidence you can re-check yourself.
Katcher's answer:
Most brand protection vendors hide pricing behind a sales call and annual contract. Katcher publishes its prices, starts with a free scan, and runs month to month.
It also does the takedown work, not just the monitoring. Katcher files every report that needs no signature from you (Google Safe Browsing, the host's abuse desk, the registrar, the CDN and the payment processor), then chases and re-checks until the store is offline. For copyright and trademark notices, which need your sworn statement, it prepares the notice with every field filled from the evidence, so you review it and send it from your own address. Katcher never signs anything as you.
Katcher's answer:
Online brands and ecommerce stores whose names, product photos and descriptions get copied by fake storefronts. That includes stores on Shopify, WooCommerce, Magento, BigCommerce and custom platforms.
It suits founders and small teams who want fake stores found and closed without hiring a brand protection agency, and it scales up to multi-brand businesses on the Scale and Enterprise plans.
