We empower customers to configure firewall rules that allow, block, monitor, or CAPTCHA web requests based on IP addresses, HTTP headers, SQL injection patterns, cross-site scripting, and more. Our service integrates seamlessly with CloudFront, Application Load Balancer, API Gateway, and AppSync—supporting cloud, on-premise, and hybrid deployments. We've built a highly available, low-latency distributed system that propagates security changes worldwide in minutes, enabling customers to respond to active threats instantly. Our deep integration with CloudWatch, AWS Firehose, AWS Config, and CloudFormation gives customers complete visibility, compliance tracking, and automated deployment capabilities.
