AWS Firewall Manager
AWS Firewall Manager centralizes firewall rule management across your accounts. It handles the concrete work of enforcing security policies and configuring WAF rules at scale. This saves time by automating the tedious process of manually applying rules to individual resources or services within your AWS environment.
It fits teams managing complex multi-account setups who need consistent security posture. The real trade-off is the lack of a free tier. You pay as you go, so costs accumulate based on usage rather than a fixed baseline, which can surprise teams expecting a zero-cost entry point for basic management tasks.
