Hey David,

Thanks for the video. When you mention having a firewall in your comment, what exactly do you mean? Do you set up the firewall yourself, or is it provided by DigitalOcean droplets or Kamal? I am considering using Kamal instead of a PaaS platform that handles security automatically. Should I take additional steps to secure Kamal? Also, is there an advanced video on firewalls available?

Thanks!
