Configuring AWS Verified Access for ZTNA

Overview

AWS Verified Access is a Zero Trust Network Access (ZTNA) service that provides secure, VPN-less access to corporate applications hosted in AWS. It evaluates each access request in real-time against granular conditional access policies written in the Cedar policy language, ensuring access is granted per-application only when specific security requirements such as user identity and device security posture are met and maintained. Verified Access integrates with AWS IAM Identity Center, third-party identity providers (Okta, CrowdStrike, JumpCloud, Jamf), and device management solutions. For multi-account deployments, AWS Resource Access Manager (RAM) enables sharing Verified Access groups across organizational units.
