What is AWS Control Tower?

AWS Control Tower is a fully managed service provided by Amazon Web Services (AWS) that simplifies the process of setting up and governing a secure, compliant, multi-account environment. It is designed to help organizations establish and manage their AWS workloads with best practices for security, operations, and compliance. It offers a single dashboard with pre-configured templates and policies that enforce security and compliance best practices throughout the business for managing and watching over many AWS accounts.

Administrators may apply standard configurations and settings, control identity and access, establish and manage new AWS accounts, and check compliance uniformly using the AWS Control Tower. The AWS Control Tower enables seamless implementation of “AWS Control Tower guardrails,” which are automatic security and compliance measures. These guardrails promptly identify and correct any potential security issues, ensuring a secure and compliant AWS environment.
