If you are in a country that blocks access to some popular internet services such as Facebook, Google, Twitter and Whatsapp in China, or Telegram in Russia and Iran, the only way to connect to this service is to use vpswala.org. But an important note for you is to stay aware of the legal regulations in the country. You certainly don’t want to break the law of accessing certain prohibited sites even if you use a VPN. If KRACK can tap the data of Wi-Fi users who are secured with WPA2 encryption without knowing the encryption key, instead ROCA can extract private keys with only a public key. The best answer to KRACK and ROCA threats is a VPN that will still protect its user data even though the Wi-Fi hotspot has been exposed to these two security threats.

Another advantage of a VPN is anonymity. With a good VPN connection, you can be protected and your profile or personal data will be protected. But is solely only the benefits gained by using a VPN? Certainly not. VPN has three weaknesses. The first drawback is that it uses encryption, in general VPN will cause connections to be relatively slower than without VPN. The second drawback is the increased complexity compared to not using a VPN. While the third disadvantage is the additional cost of using a VPN.

It is important to know, VPN provides a private network of an entity that can be accessed in public infrastructure, especially on the internet. VPN can exchange data from each user in an efficient way on a public or shared network as if the user is already connected directly to a private network. Commercial VPNs are capable of carrying out traffic on encrypted tunnels. Then they can route the road traffic by going through a server at the location chosen by the user. This can be possible if the information, IP address, and anything that is an online activity will always be maintained.
