DigitalOcean announce the release of Cloud Firewalls.
Cloud Firewalls help secure your Droplets and are free to enable. You can define which ports are visible on your Droplets and control which resources can access them. All without having to install and configure more software.
It’s designed to be easy to use with groups of resources, scales as you grow, and is perfect for production environments.
Cloud Firewalls are free for all Droplet customers.
