@OpenSource-Ghost while I give you the benefit of the doubt for trying to assist and be as informative as possible I have however removed your reply due to the lack of direct response and of substantive evidential based sources for some of the claims.
@Reflux and @Kenny33 I've removed your comments regards OpenWRT and Routers as it isn't specific to the topic and initial question. (Feel free to open an OT thread specific to Routers, Firmware and VPN's specifically.)
@kopolee11 for similar reasons please feel free to open another thread asking about TOR usage, apps and configuration.
A well known and respected VPN provides the following basic guidance for VPN uses:
Do you really need a VPN?
Despite what many VPN providers advertise VPNs are useless (at best ineffective) at:
- Achieving anonymity.
- Preventing Google or Facebook from collecting your private data.
- Preventing unwanted profiling by social networks or search engines.
- Providing better security when ‘working from home’.
- Protecting your passwords.
- Hiding your mobile phone location (GPS).
- Helping you avoid data breaches on services you use online.
- Defending against “cyber threats” and identity theft.
Do not rely on a VPN to protect you in any of the above scenarios.
However, a trustworthy VPN can be very effective at:
- Encrypting your data so your ISP or mobile network provider cannot monitor or log your online activity. Without a VPN, HTTPS still exposes the domain name or IP you are visiting to the ISP.
- Encrypting your DNS requests so your ISP or mobile network provider cannot monitor or log the domains you visit.
- Increasing your security on untrusted public networks by preventing MITM attacks.
- Masking your IP address from websites and servers you connect to.
- Circumventing censorship or geographical blocks on websites and content.
