The word "VPN" is being used more and more. It is often associated with terms such as "anonymity", "proxy", "geo-blocking" and others. But what is this software really and how does it allow us to surf with peace of mind? In this article, we will analyze the advantages and disadvantages of using a VPN, as well as the way it works and the main reasons why it is important to use it.
What is a VPN?
VPN is a network service used by individuals to protect the identity and security of data transmitted online by encrypting traffic and preserving anonymity. In corporate jargon, the term is used to identify an extension of the private local area network (LAN) that allows employees to access the corporate network without being physically present.
VPNs are also particularly used by journalists and users in dictatorial countries. In these countries, they allow access to portals and applications like Google or YouTube.
Why choose Express VPN?
Reasons to choose Express VPN are many. ExpressVPN has an excellent reputation in the VPN market for a reason. With great features, an incredibly convenient location, and incredible performance, it's a service provider that clearly deserves a place among the best VPNs of our time. ExpressVPN offers a kill switch for those who really value their security. A kill switch is a software security feature that disconnects your device from the Internet connection if the VPN connection is lost or interrupted for any reason.
Why use a VPN?
Using a VPN tailored to your needs allows you to :
- make your browsing anonymous by not showing your IP address to the ISP (Internet Service Provider);
- encrypt network packets sent and received, avoiding sniffing attacks;
- circumventing imposed limits such as geographic blocking, blocking of specific sites, etc;
- access the company network from home via a secure channel;
- prevent large companies from conducting profiling activities;
- to preserve the privacy of Internet users and prevent third parties from having access to their data.
However, it is necessary to point out how improper use or configuration of a VPN and inappropriate behavior eliminates any benefits due to the use of the software itself. If you allow an application such as Google Maps to acquire data via the use of GPS, your location is discovered. Similarly, accessing the Facebook even under VPN will not eliminate the profiling processes that the web giant imposes on each of its users.
Other factors to watch out for are cache and cookie cleanup which can still lead to de-anonymization.
Internet has inevitably become the place where everyone exchanges a lot of data, often as sensitive and personal. Corporations, governments and hackers all have a vested interest in undermining our freedom and privacy. Adopting a VPN connection allows users around the world to defend themselves against targeted attacks, bypass controls for a completely uncensored and unmanipulated Internet, and preserve their anonymity.
