There are certain points you need to keep in mind when you’re looking for an unblock sites software.
First and foremost is the unblock sites software a proxy software or a VPN software? We explained earlier that in many ways a VPN is better than proxy because it’s safer, more effective and more stable.
Secondly, if you decided to download a VPN unblock sites software, which VPN protocols are used? There are many different VPN protocols: PPTP, SSTP, SSH, L2TP, OpenVPN. OpenVPN is the most reliable VPN protocol used by unblock sites software but it’s not supported on some operating systems. When this is the case, L2TP is the second best choice; Both VPN protocols feature 256-bit encryption. And better yet than OpenVPN is OpenVPN over SSH tunnel but this feature is rare to find.
Another important point is servers’ locations. For example, if you’re looking for an unblock sites software to be able unblock BBC iPlayer, you’ll need a server located in UK. If you’re for an unblock sites software to be able unblock Netflix, you’ll need a server located in USA and so on. Anyway, you should always look for an unblock sites software that located its servers in countries where Internet connection is fast and reliable such as Germany and Russia or countries with low internet penetration percentage.
Finally, you should at least be offered a decent free trial period and it would be better if the free VPN trial doesn’t require credit card.
