user: Is there a way to block incoming requests from coming from the service Vercel and Render.com?
assistant: To block incoming requests from services like Vercel and Render.com, you can use Vercel's Firewall to block specific IP addresses. Here's how you can do it:

1. **Identify IP Addresses**: Obtain the IP addresses used by Vercel and Render.com. This might involve reaching out to their support teams or checking their documentation for any publicly listed IP ranges.

2. **Configure Vercel Firewall**:
   - Navigate to the Firewall settings in your Vercel project.
   - Add an IP block rule by clicking on “Configure” and scrolling to the “IP Blocking” section. Use the “+ Add IP” option to enter the IP addresses or CIDR ranges you wish to block.
   - Ensure that you specify the correct host (domain name) for which you want to block these IP addresses.
   - Review and publish the changes to apply them to your production deployment.

3. **Account-Level Blocking**: If you are on an Enterprise plan, consider using account-level IP blocking for broader control.

4. **Managing Dynamic IPs**: If Vercel or Render.com use dynamic IP addresses, regularly update your block list to maintain its effectiveness.

By following these steps, you can effectively block incoming requests from Vercel and Render.com using Vercel’s Firewall features.
user: No, I want to block requests from Vercel and Render.com, also the IP addresses change.

[SYSTEM]: This user provided a web data: Blocking requests from Vercel and Render.com can be challenging due to their dynamic IP addresses. Here are some considerations:

1. **Dynamic IP Addresses**: Both Vercel and Render.com use dynamic IP addresses, which means that blocking specific IP addresses may not be effective as they can change frequently.

2. **Alternative Approaches**:
   - **Custom Headers**: Implement a custom header in your backend that can be verified by your application. This way, you can reject traffic that doesn't contain this header, providing an additional layer of security.
   - **Proxy**: Consider adding a proxy in front of your service to manage incoming requests. This can help filter out unwanted traffic.
   - **Advanced Authentication**: Use additional authentication methods like user/password or authentication keys to secure your backend infrastructure.

3. **Vercel Firewall Limitations**: While Vercel's Firewall allows you to block specific IP addresses, it may not be effective against dynamic IP addresses used by Vercel and Render.com.

4. **Secure Compute**: For Enterprise customers, Vercel Secure Compute offers private connections between Vercel Functions and backend infrastructure, which can help restrict access to your backend.
