It can happen that the tracker fires successfully, but is blocked by your website. Our tracker often blocked by a strong Content Security Policy (CSP) or Cross-origin resource sharing policy (CORS)  In this article we'll answer the following questions: : - [What is a Content Security or CORS Policy?](https://help.leadinfo.com/en/why-is-the-leadinfo-tracker-blocked-on-my-website#what-is-a-content-security-policy) - [How do I know if my CSP blocks Leadinfo?](https://help.leadinfo.com/en/why-is-the-leadinfo-tracker-blocked-on-my-website#How-do-I-know-if-my-CSP-blocks-Leadinfo) - [How do I know if my CORS blocks Leadinfo?](https://help.leadinfo.com/en/why-is-the-leadinfo-tracker-blocked-on-my-website#cors) - [How do I use Leadinfo with a CSP?](https://help.leadinfo.com/en/why-is-the-leadinfo-tracker-blocked-on-my-website#HOW)   #### **What is a Content Security Policy (CSP)?** The CSP is an extra layer of security that allows developers to restrict the behavior on their website or application. Done correctly, it detects and prevents attacks from data theft to code injection. This policy is set up by your team or via a security tool.    There is no need to worry when Leadinfo is blocked by your CSP. You or your team can add Leadinfo to the rules of your CSP.   #### **What is a Cross-origin Resource Sharing Policy?** Cross-origin Resource Sharing (CORS) is an important security feature that enables web applications to request resources from different domains. This functionality is essential for integrating third-party APIs and accessing various resources, such as videos, fonts, or weather data. CORS works by ensuring that your browser seeks permission from these external servers before allowing any data exchange to take place.There is no need to worry when Leadinfo is blocked by your CORS-policy. You or your team can add Leadinfo to the rules of your CORS-Policy.     #### How do I know if my CSP blocks Leadinfo?   **Step 1:** In Chrome, go to your website and right-click on your website and select "**Inspect**". ![](https://help.leadinfo.com/hubfs/Group%20686-png.png)   **Step 2:** The developer console will pop up.
