Firewalls place a barrier between your servers and other machines on the network to protect them from external attacks. Firewalls can be host-based, which are configured on a per-server basis using services like IPTables or UFW. Others are network-based, designed to stop traffic before it ever reaches the individual machine.
DigitalOcean Cloud Firewalls, available in all regions at no charge, provide a network-based, stateful firewall service for your DigitalOcean Droplets. They block all traffic that isn’t expressly permitted by a rule. You can define the Droplets protected by a Firewall individually or by using tags, which makes it easier to manage your Droplets in bulk and apply Firewall rules as soon as you create a new Droplet.
