Anonymous VPN For Secure Browsing
If you want to keep your browsing habits private as far as is possible today, VPN services allow you to do so. VPN is recommended in an age of greater connectivity, where personal information is easy to find and exposing your browsing habits, political position, and occupation, forum discussions etc. could lead to loss of reputation or job termination. Millions of people use VPN services to protect privacy.
What is VPN?
VPN (Virtual Private Network) is essentially a secure network over a public network, like the Internet, or a private network that the service provider owns. It prevents the IP addresses of users from being visible to others on the Internet.
The service lets individuals and offices browse the internet or access their organization's veiled from public eyes. Educational institutions, large corporations and government agencies also use VPN to allow remote users to connect securely to a private network. Marketers and people in business want to keep their browsing habits protected from competitors, and VPN helps to cover their tracks.
This technology is also useful for individuals. Many websites monitor visitor information. There is a chance of your data falling into the wrong hands. Anonymous VPN lets you browse securely and eliminate this risk of exposure. VPN is especially recommended if you engage in file sharing of software, music, videos, if you advertise or research online, browse the web or participate in Internet forums.
How does VPN work?
There are many different protocols that VPN service providers use to keep their clients anonymous. Each one of these protocols has a slightly different way of keeping data and online communications secure.
Protocols used by VPN services include:
IP Security (IPSec) - either using tunneling or transport mode to securely encrypt data. IPSec is often used along with other protocols.
SSL (Secure Socket Layer) and TLS (Transport Layer Security) use a cryptography technology. In order to initiate a connection, a secure, "handshake" method of authentication between the client and servers is used.
PPTP (Point to Point Tunneling Protocol) is most commonly used because it is straightforward, included with Windows OS and offers easy maintenance.
L2TP (Layer 2 Tunneling Protocol) tunnels data between two websites, and is often used together with IPSec.
These protocols are the most secure and reputed, and when choosing a VPN technology to use, it is useful to find out which of these protocols the service will encrypt your data with. In general, VPN uses very high levels of encryption and algorithms to make sure data traffic is protected from interception of data.
What are the advantages and disadvantages of VPN?
VPN is a very affordable way of keeping your data secure or creating a private network. Many corporations use private leased lines, but these can be more expensive. Individuals will find VPN services more cost effective as well. With VPN, corporations can save money on software and hardware, and enjoy the flexibility, speed and ease of achieving data security.
Some issues that still exist with VPN include the fact that if there are network problems outside the private network, any downtime that results is beyond the VPN administrator's control. It is recommended for private corporations to use trusted, reputed VPNs that also offer Quality of Service management. Another issue that users may face is that VPN offerings from one service provider may not be compatible with those of another. Despite these issues, however, VPN continues to be widely used as the most secure and affordable form of communications over the Internet.
Is VPN Truly Anonymous?
Note that VPN cannot solve all anonymity problems. Even with the best anonymous VPN services, there will be at least one piece of information to set you apart from other users on the VPN. For Bitcoin, for instance, this is your wallet. For other major providers it is a set of IP addresses. To make an analogy, a VPN is like a curtain that keeps your activities private even if your house address is public.
VPN does, effectively, greatly increase your privacy and security online. This is a very realistic goal, and if the VPN vendor you are considering is transparent about their limitations, you can go ahead and safely trust them to keep your online activity as private as is possible today.
