I see familiar post online, and some on this forum about VPNs, and A Virtual Private Network (VPN) serves two small aspects of online security and privacy.
Firstly, it encrypts all your internet traffic from your device to the VPN's exit point. This encryption ensures that your Internet Service Provider (ISP) can only perceive encrypted data without any visibility into the actual content being transmitted. In other words, your online activities are still accessible to the websites you visit through fingerprinting.
Secondly, a VPN operates by providing the website you are visiting with the IP address associated with the VPN server, rather than revealing your ISP IP. By substituting your IP address with that of the VPN, your ISP IP and location are concealed, granting you a small extra layer of privacy from potential IP grabbers, IP profiling or DoS attacks.
If anyone think a VPN safeguards your online browsing, you're mistaken, completely mistaken. VPN's only functions lie in encrypting your traffic from your device to the VPN's exit point and providing the website you are visiting with the IP address associated with the VPN server.
