This is what I've been using on my Shopify site, so people can't steal my product images & text. https://apps.shopify.com/vault-antitheft-protection-app
Is there something similar that's available for Magento?
Magento natively supports adding watermarks to images: https://docs.magento.com/user-guide/catalog/product-image-watermarks.html
There are also addons like https://marketplace.magento.com/smartframe-module-smartframe.html
You can also speak to your Magento web host about any web application firewall (WAF) options that can be enabled to block scapers and such.
Best of luck!
