To set up a DMZ for your business network, you will need to do the following:

1. Identify the public-facing servers and services that you want to make available to the public.
2. Build and configure firewall rules to allow public access to the appropriate services.
3. Configure a DMZ zone.
4. Deploy the public-facing servers or services in the DMZ.
5. Enable web filtering and Data Loss Prevention (DLP) services to minimize the risks of malicious actors.
6. Continuously monitor the DMZ and apply security patches when necessary.
