What VPN Offer Individuals and Businesses
Virtual Private Networks offer individuals a secure yet uncomplicated way to protect their identity and location while the internet is accessed from government surveillance and hackers.

VPN users can side-step geo-blocked locations and censorship problems as well as prevent entities or individuals from spying on their every move on the internet and VPN use on a daily basis includes browsing privacy, circumventing restricted sites, censorship bypass, and safe downloading of files.

How VPNs Work & Protect
HTTPS is a protocol that encrypts connections to any website and is highly effective in safeguarding passwords, login details and online purchases especially banking details. SSL certificates are installed on secure websites and act like encrypted keys to completely secure the connection between the site and visitors or purchasers. Information regarding transactions is secure between the website and the devices it is made from since most sites use HTTPS by default. At the same time VPNs encrypts all internet activities to further increase security and privacy through the tunnelling protocol.
Tunneling offers the ultimate protection, when a web address is entered the files are basically broken down into packets sent to user’s computer from the server source, tunnelling takes the individual packets place it in a single packet and then send that out. The outermost layer camouflages the contents of the packet. VPNs add a buffer or layer between browsing activities and other entities trying to survey it. It is these encrypted layers of data that allows access to networks from remote destinations or in case of free Wi-Fi hotspot used activities leaves a VPN footprint to secure that no trace of the device used are visible or left behind. Without the proper encryption key to unlock contents attackers or networks are unable to view the contents of a tunnel.
Different protocols are used by VPNs to send users encrypted data via tunnels, and the protocols act like a framework or a single language understood by the specific network that receives and sent the information.
For example, most popular websites use OpenVPN beyond the SSL certificates or IPsec to send encrypted and secure data between two devices. IPsec exists of two sub-protocols that provide all the information and instructions that are needed by the VPN in order to secure the packet sent or received. The two sub-protocols are ESP – Encapsulated Security Payload and AH Authentication Header. The ESP encrypts all data while the AH hides the information of the sender of the packet until it reaches its location or destination.
PPP is a common VPN for remote access and Point-to-Point Protocol while L2F – Layer 2 Forwarding is an additional PPP based protocol.
What to Consider in Selecting A VPN
VPN services should be evaluated on three basic criteria’s including protocols, server locations, and price. While we briefly discussed most of the protocols Secure Sockets Layer or SSL is used by some of the major sites like Amazon and Google and the highest recommended protocol is OpenVPN for its reliability and security strength.
