Public Networks and VPN Technology
[ad_1]
People are connected to the Internet almost constantly these days. There's a good chance that the cellular phone you use has a constant data connection on it. If you carry a laptop with you, you're obviously doing so that you can flip it open and log onto the Internet for work or pleasure in remote locations. The problem with logging on over public networks is that you have no control over the security protocols that they have in place. This sometimes means that you end up exposing yourself to risks that you would never tolerate on a network over which you have control.
There are several different solutions to this. One of them is to simply not use public network set all. This can be inconvenient. Particularly where mobile Internet devices are concerned, cellular carriers oftentimes charge high prices for data overages. Unless you have an old contract that still allows you to get unlimited data, your cell phone provider probably does charge you after a certain amount of data has been downloaded by your phone. This means that public networks are sometimes the best options for checking your e-mail and other tasks.
Public networks are also excellent for meeting with people if you need to collaborate for work purposes. A great many people are now employed from their homes. This means that there is no central office for them to meet at with their colleagues or with people who they are working with on a project. Working on a public Internet connection is oftentimes the best option for these workers. You can have the convenience of a public network with all of the safety of a tightly controlled private network with a VPN service.
The VPN service will work no matter where you're located. These services are not bound to your home network. If you need to connect to the Internet over a public network, doing so over a VPN network ensures that your communications are encrypted and that you're not at risk of being spied upon by individuals who are either just snooping or who may have far more sinister intentions for any information they find.
Public networks will always be inherently dangerous. You simply have no way of accurately assessing how much time the owners spend on their security and how good of a job they do in that time. A VPN network can make public surfing safe and productive.
