VPNs can have a major impact on network performance and speed. Since VPNs use encryption to secure data traveling between two points, they can create significant overhead that can slow down your connection speeds. Additionally, depending on the configuration of your network, using a VPN may require additional steps to ensure that traffic is routed correctly, which can also decrease performance. As a result, it’s important to understand how your network is set up and choose a VPN provider that offers the best performance for your needs.
