IVPN is a VPN provider that supports a variety of security protocols. The main feature of this, and other services like it, is that it provides a layer of anonymity between the user and the servers they connect to on the Internet.
How IVPN encryption works
IVPN uses different encryption protocols so that data can not be captured during transmission. You connect to the server provided by the company, not directly to the server you are retrieving information from. For example, if you were in a country where Internet traffic is censored and you want to read an American or British newspaper site without being blocked, you can connect to the IVPN server, get the newspaper through that server and read it without any of the content being censored.
Encryption is an additional feature that prevents your traffic from being captured and decoded by snoopers. The encryption basically encrypts every bit of data in a way that makes it unclear to everything except your computer and the server you retrieve it from. In this way, the intercepted traffic can not be read and, more importantly, the destination and the origin do not show red flags for anyone watching. Traffic is often directed over harmless ports that do not attract any attention.
Is it expensive?
Like most subscription services, IVPN offers discounts to customers who purchase longer-term commitments for the service. Some users choose to buy a month of services like these to see if they really need them and others opt for longer subscriptions if they know they will need them often.
Who needs these services?
While encrypting all of your Internet traffic in a nation that does not censor traffic may seem a little strange, many do so for simple security reasons. This is very useful, for example for people who log in to their work networks for their home and who need to ensure that all information that may be sensitive is transmitted via a secure connection. Some users simply get annoyed at the amount of curious sites run by advertisers and other completely legitimate but very intrusive services. This type of service allows such users to log in to these websites without revealing their actual IP address.
How does it hide my IP?
IVPN uses several different protocols. They have names like OpenVPN, IPsec and freeRadius. They are all basically just ways to make traffic to and from your computer anonymous. When you log in to a website, the website thinks that you are logging in from one of the servers on the IVPN network instead of your own internet service providers. For example, you can be in Meridian, Mississippi and log in to a page with an IP address that showed that you were in Ireland, if the company happened to have a server there and you logged in via it. The landing page only sees the traffic from Ireland, not from the original server you are coming from, which is a great advantage of services like these for users who want privacy while browsing.
