Evolving Beyond Legacy VPN with Modern Security Solutions

This white paper discusses the transition from legacy virtual private network (VPN) technologies to modern security solutions, specifically cloud-delivered Zero Trust Network Access (ZTNA). It outlines the limitations of traditional VPNs, including security vulnerabilities and performance issues that arise from remote access demands. The paper describes how ZTNA, built on zero trust principles, offers a more secure and efficient alternative by authenticating users before granting access to applications. However, it also highlights the challenges organizations face when integrating legacy applications with ZTNA, which can lead to prolonged reliance on VPNs. The document presents a solution, Netskope One Private Access, which combines ZTNA and Software-Defined Wide Area Networking (SD-WAN) capabilities, allowing for a complete transition away from VPNs while enhancing security and user experience. The paper emphasizes the importance of addressing legacy application compatibility and the benefits of adopting a unified approach to secure remote access.
