Traditional VPNs grant excessive access, slow down user experience, and have become a top ransomware attack vector. Zero Trust Network Access (ZTNA) provides better security, performance, and user experience. Here is why your business should make the switch.
Traditional VPNs were designed in the 1990s for occasional remote access. In 2026, with hybrid work as the norm and ransomware as the dominant threat, VPN technology has become a security liability rather than a security control.
The problems with traditional VPNs: Once authenticated, users get broad network access — perfect conditions for ransomware lateral movement. VPN concentrators have a long history of critical vulnerabilities (Pulse Secure, Fortinet, Cisco have all had major exploits). VPN performance is poor, especially for cloud-based applications, because all traffic backhauls through corporate data centers. Users hate VPNs, leading to security workarounds. Scaling VPN to support a fully remote workforce is expensive and operationally complex.
Zero Trust Network Access (ZTNA) takes a fundamentally different approach. Instead of granting network access, ZTNA grants access to specific applications based on identity, device posture, and context. Every connection is verified, never trusted by default. Key advantages: Application-level access (no network exposure), continuous verification (not just at login), better performance (direct routing to cloud apps), simpler administration, and elimination of VPN as a ransomware vector.
Leading ZTNA solutions: Microsoft Entra Private Access (formerly Azure AD Application Proxy) — best for Microsoft 365 environments, included in Microsoft Entra ID P2 licensing. Cloudflare Access — strong CDN integration, excellent performance. Zscaler Private Access — enterprise-grade with extensive integrations. Cisco Duo Network Gateway — good for Cisco environments.
CloudTechForce migration approach: Audit current VPN usage and applications, deploy ZTNA gateway in parallel, migrate user groups in waves, decommission VPN after full migration. Typical timeline: 8-12 weeks for a 200-person organization. Results: improved security posture, 40-60% better application performance, reduced operational costs, and elimination of VPN as a security risk.
