Quick answer

What is Zero Trust & Business VPN?

Business VPNs connect remote users to company networks through encrypted tunnels. Zero trust network access (ZTNA) instead grants access to specific applications after checking identity and device, and SSE/SASE platforms add web security and firewall services in the cloud.

Remote work and cloud apps have pushed many teams from traditional VPNs toward zero trust access.

This category covers gateway VPNs (NordLayer, Proton VPN for Business, OpenVPN Access Server), ZTNA and mesh tools (Twingate, Tailscale, NetBird) and enterprise SSE/SASE (Cloudflare Zero Trust, Zscaler, Check Point, Cisco).

Prices range from free tiers to six-figure enterprise contracts. The profiles below summarise dated 2026 sources and estimates, and are research aids, not rankings.
