Managed rule groups

Managed rule groups are collections of predefined, ready-to-use rules that Amazon writes and maintains for you. Amazon managed rule groups are available for free to Network Firewall customers.

Automatic updates

Keeping up to date on the constantly changing threat landscape can be time consuming and expensive. Managed rule groups can save you time when you implement and use Network Firewall. Amazon automatically updates managed rule groups when new vulnerabilities and threats emerge. Amazon updates managed rule groups once a day to once a week.

In some cases, Amazon is notified of new vulnerabilities before public disclosure due to its participation in a number of private disclosure communities. In those cases, Amazon Network Firewall can update rule groups and deploy them to your environment before a new threat is widely known.
