VPN (English Virtual Private Network - virtual private network) is a secure encrypted connection of the user to the network, with which he can bypass local restrictions and maintain confidentiality.In fact, security is one of the main benefits of using a VPN. Top-notch VPNs use 256-bit encryption to protect your data and personal information. Moreover, look for a VPN with a no-logs policy: such a VPN will not save your browsing history and your personal data on its servers. The kill switch and DNS and IP address leak prevention are also important security features.Well, if you are interested in what vpn I use, then this https://www.vpnunlimited.com/blog/history-vpn-whys-whens .An additional layer of protection for VPN services is their own DNS (Domain Name System). This is the “Internet phone book”, where IP addresses and URLs have been added instead of people and numbers, respectively.
Ad blockers do the same. This is a higher level of user data protection. The simplest blockers simply hide advertising banners, while reading the user's browser history. If the software blocks banners at the DNS level, the user's browser history becomes inaccessible to advertisers and surveillance stops completely. Popular smartphone apps that work this way are Blokada, NextDNS, and AdGuard.
