+title: Real-time logo match preview
+description: Preview potential logo matches and adjust similarity thresholds before saving your Brand Protection queries
+date: 2026-03-18
+---
+
+We are introducing **Logo Match Preview**, bringing the same pre-save visibility to visual assets that was previously only available for string-based queries. This update allows you to fine-tune your brand detection strategy before committing to a live monitor.
+
+### What’s new:
+
+- Upload your brand logo and immediately see a sample of potential matches from recently detected sites before finalizing the query
+- Adjust your similarity score (from 75% to 100%) and watch the results refresh in real-time to find the balance between broad detection and noise reduction
+- Review the specific logos triggered by your current settings to ensure your query is capturing the right level of brand infringement
+
+If you are ready to test your brand assets, go to the [Brand Protection dashboard](https://developers.cloudflare.com/security-center/brand-protection/) to try the new preview tool.
