What is difference between ZTNA and VPN? — VoltronAI

As organizations increasingly embrace remote work and cloud-based services, securing access to applications and data has become a paramount concern. Two technologies that aim to provide secure access to resources are Zero Trust Network Access (ZTNA) and Virtual Private Networks (VPN). This comprehensive guide will discuss the differences between ZTNA and VPN, their respective advantages and disadvantages, and their suitability for different use cases.

Understanding Virtual Private Networks (VPN)

Virtual Private Networks (VPN) are a well-established technology that provides secure remote access to an organization’s network resources. A VPN creates an encrypted tunnel between a user’s device and the VPN server, ensuring that all data transmitted through the tunnel is secure from eavesdropping and tampering. Once connected to the VPN server, the user’s device is virtually part of the organization’s network, allowing access to network resources as if they were physically present in the office.
