ZTNA vs VPN: Which Model Fits Today’s Enterprises?
As enterprises modernise their security architecture, they face an essential question: ZTNA or VPN? Which remote access security model is suitable to meet the current threat? The emergence of hybrid work has expanded the attack surface, and adversaries are targeting identity, endpoints, and gaps in network trust. Now is a good time for organisations to re-evaluate their legacy VPNs, which cannot provide security at the speed of the changing environment. Why Traditional VPNs Fall Short For a long time now, VPNs have been at the core of remote access solutions; however, these limitations expose organisations to unnecessary risks. Implicit trust model - After the user is authenticated, they are granted access to the entire network, creating a significant opportunity for lateral movement. Performance bottlenecks - By backhauling user traffic through a centralised gateway, the bandwidth consumed on the connection will reduce user productivity. Poor scalability - Legacy VPN architectures ca...
