One of the possibilities you have to hide your identity in the network and at the same time to encrypt the traffic can prevent it can be collected by third parties and access to geographically blocked sites, however, it is possible that VPN connections are not so secure as they should be by default, so you have to take several factors into account with which to improve the security of these.
It is possible to automatically configure your operating system and firewall in a way that only allows connections through secure networks, however, this task can be somewhat complicated for many users.
Fortunately there are much simpler and faster alternatives that will ensure that you only communicate through an anonymous server and your identity and privacy are assured.
This tool constantly checks your IP address. At the time of this change (for example, if your computer is disconnected from the VPN server) this application will automatically cut the connection of different configured applications, for example, a P2P client in case you are using VPN connection for this purpose.

VPNcheck is a tool that constantly checks your connection and shows us a notification when your network adapter changes. In this way you can know at all times if you have a secure connection established or, otherwise, it is possible that you are navigating without protecting your identity connected directly to the network.
Protect against DNS data leak
When you navigate through a VPN connection generally all traffic will be done through this server, however, it is possible that sometimes a phenomenon known as “DNS data leakage” occurs where DNS connections are not encrypted through the server VPN, but these are done directly, without encryption.
Protect against IPv6 and PPTP failures
Since 2010 it was made public that all users browsing through PPTP and IPv6 could be vulnerable to a security breach that could reveal their real IP address.
We can avoid this by typing in a CMD window in Windows:
netsh interface teredo set state disabled
To avoid this vulnerability in Ubuntu you must type the following lines in a terminal:
echo “ipv6 #No” | sudo tee -a /etc/sysctl.conf
echo “net.ipv6.conf.all.disable_ipv6 = 1” | sudo tee – /etc/sysctl.conf
echo “net.ipv6.conf.default.disable_ipv6 = 1” | sudo tee -a /etc/sysctl.conf
echo “net.ipv6.conf.lo.disable_ipv6 = 1” | sudo tee – /etc/sysctl.conf
A tunnel through another tunnel
We can apply an additional layer of security to your connections simply by redirecting your VPN connection through other VPN servers, and even connecting to the TOR network through these servers.
In this way the encryption will be double and will prevent that you can be identified by your supplier or by any of the servers. The only drawback is that you must hire two tunnels so this can work, therefore, the investment will be higher than having to pay two subscriptions.
Pay with an untraceable currency
Generally the servers allow to pay the subscription through different methods. It is advisable to use a secure and difficult to track payment method, for example, Bitcoin, so that if they try to associate your traffic with your VPN server IP and this to us, they can not do it through the bank data provided to do the payment.
We should always avoid paying with PayPal and similar platforms to prevent this from revealing your identity.
Use VPN servers that guarantee the privacy of your users
How do you protect your VPN connections to ensure that your identity and privacy can not be compromised?
