What is Hashicorp Sentinel?

HashiCorp Sentinel is a policy-as-code framework designed to be embedded in infrastructure-as-code workflows. It allows organizations to define and enforce policies across their infrastructure, ensuring compliance, security, and operational best practices. Sentinel policies are written in a dedicated language and can be used to control various aspects of infrastructure provisioning, deployment, and management within HashiCorp tools like Terraform, Vault, Consul, and Nomad. It enables centralized policy management, version control, and testing to improve governance and reduce risks associated with infrastructure changes.
