# Web Scanner The Web Scanner is a manual tool within the extension that allows you to scan any website before interacting with it. **NOVA** performs an analysis in seconds, all automatically. Unlike Safe Browsing, this scan is active and detailed: it analyzes domains, website structure, certificates, the presence of trackers, embedded malicious code, and connections to suspicious smart contracts. It can also detect if the site has been previously reported as dangerous. The interface displays a clear report with the risk level (*low/medium/high*), potential threats detected, and suggestions from the AI ​​Agent if enabled. **Use cases:** * *Verify links shared by unknown users* * *Check if a new dApp is safe before connecting your wallet* * *Confirm the authenticity of a site that looks similar to the original (e.g., an exchange or DeFi tool)* --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
