Generated on 13 Mar 2026

DigitalOcean Cloud Firewalls are a network-based, stateful firewall service for Droplets provided at no additional cost. Cloud firewalls block all traffic that isn’t expressly permitted by a rule.

## Getting Started

[How to Create Firewalls](https://docs.digitalocean.com/products/networking/firewalls/how-to/create/index.html.md): Create a cloud firewall to restrict network traffic to and from specified Droplets.

[How to Configure Firewall Rules](https://docs.digitalocean.com/products/networking/firewalls/how-to/configure-rules/index.html.md): Create, modify, or delete firewall rules to restrict Droplets’ inbound and outbound traffic based on ports, sources, and destinations.

[How to Add and Remove Droplets from Firewalls](https://docs.digitalocean.com/products/networking/firewalls/how-to/manage-droplets/index.html.md): Add Droplets to a firewall by name or by tag to apply the firewall’s rules.

## Cloud Firewall Management

[How to Destroy Firewalls](https://docs.digitalocean.com/products/networking/firewalls/how-to/destroy/index.html.md): Destroy a firewall to remove it permanently from your account. Destroying a firewall does not destroy the Droplets that were associated with it.
