You probably have many good reasons to utilize a VPN, but I wanted to take a few moments to outline what VPNs can specifically do for you as well as areas where VPNs may not address your specific security and privacy needs.
Benefits and Reasons To Use a VPN
While reviewing every detail about VPNs is beyond the scope of this blog, let’s talk about a few common reasons for utilizing it:

Maybe they see that traffic exists, but it is typically encrypted to be unreadable.
