From legacy architecture to Cloudflare One

This post explains how Cloudflare and CDW help organizations migrate from legacy VPN architectures to a Zero Trust SASE model while avoiding the risks of a "big bang" cutover.

• •CDW uses a risk-aware, tiered methodology that categorizes apps by complexity (Tier 0–3) to prevent mass simultaneous migration failures.
• •Cloudflare Access replaces traditional VPNs by evaluating every request based on identity, device posture, and contextual signals, reducing the attack surface.
• •Legacy apps are "wrapped" via Cloudflare Tunnel to add MFA and SSO without rewriting code, hiding them from the public internet.
• •Pre-migration audits cover identity provider mapping, backend dependency documentation, session persistence stress testing, and application tiering.
