Cloudflare Access is a Zero Trust Network Access (ZTNA) solution provided by Cloudflare. It verifies and secures employee and third-party access across self-hosted, SaaS, and non-web applications. Cloudflare Access checks context such as identity and device posture for every request to provide fast, reliable access without the need for a VPN. It mitigates risk and ensures a smooth user experience by enforcing context-based, least-privilege access policies.
