SDP vs. VPN: Why It’s Time to Move to Software-Defined Perimeters

SDP (Software-Defined Perimeter) is a modern approach to network security that avoids the inherent weaknesses of traditional castle-and-moat fixed perimeter security technologies such as Virtual Private Networks (VPNs). SDPs apply a software-based approach that works with today's hybrid workforces and cloud infrastructures. Unlike hardware-centric approaches, SDPs focus on protecting the logical network connecting a company's resources to its users. They offer several advantages over traditional approaches, including granularity, flexibility, manageability, security consistency, and minimized attack surface. SDP solutions are network-agnostic, resource-focused, have a small attack surface, and low overhead compared to VPNs. The modern computing environment is more dynamic and heterogeneous than ever before, making SDPs a better solution for network security than VPNs. SDPs can be paired with Zero Trust principles to provide fine-grained, context-sensitive security policies. Twingate's SDP solution makes ZTNA easier to integrate into your organization's security strategy without changing existing infrastructure or replacing the current security system.
