Differences: (*my experience)
- SSL (requires software)
- SSTP, L2TP, and PPTP (does not require software)
1. Free SSL VPN: (based on OpenVPN)
- VPN Book
- requires software & certificates to be installed.
• allows torrent activity
- fast
- Passwords change multiple times/day.
2. Free SSL, L2TP, SSTP, PPTP:
- VPN Gate
- You can choose which connection type you want.
- Torrent Activity: no restriction from SoftEther, but double-check w/volunteer.
- fast
• +3,000 free VPNs.
• Static Username & Password.
3. Free SSTP, L2TP, PPTP:
- no torrent activity allowed
- FreeVPNList
- BestFreeVPN
- JustFreeVPN
- fast
- Passwords change multiple times/day.
Note:
- if you're paranoid about anonymity, check out VPNetMon: it monitors your IP Address, and if it changes (VPN disconnects), it will close your Browser.
- i prefer SSTP, L2TP, and PPTP because they do not require any software to be installed.
- if you're unsure how to set up VPN, each service has a "How To". (very easy)
- *Some VPNs change Passwords multiple times per day. (check website before using)
- i prefer VPN over both Proxies & Tor because of the speed advantage.
- Google "Free VPN" for more.
* I cannot vouch with 100% assurance these VPNs are completely safe & anonymous. (i do not work for any of them) Some VPNs track usage, read each VPN's disclaimer. Also, i recommend selecting "Public" Mode when connected.. this prevents access to your personal data. I've used the listed VPNs only for a few weeks. Take what i've posted w/a grain of salt. Use common sense!
