Security has become a continuous problem for people are we live in a more connected world than ever. Whereas in years gone by as long as you locked up before you went out, your property was probably safe, nowadays your online life is subject to daily intrusion attempts. Everything from the smartphone in your pocket, the tablet or e-reader, to the work laptop, all are potential targets for hackers who want to steal your data, acquire your identity for resale or use your system to hide behind while they attack others computers on the internet.

Given this continued threat, it is incumbent on everyone who uses tech devices to ensure that their security is top notch. There are a number of different approaches to doing this.

Adding an anti-virus or anti-spyware package, as well as a strong firewall, can help to prevent intrusions into the system and to eradicate any file infections. However, for many people, the risks come from the internet itself, the information we freely list on web sites and that we send over unencrypted fibre optic lines which can easily be intercepted by digital thieves who are intent on doing harm.

Virtual Private Networks (VPNs)

A VPN is a service where an individual can log into a secure network of computers in order to transmit data securely or surf the internet anonymously.

To connect to the service, the subscriber logs in with the user and password combo. This information is exchanged with similar information at the VPN server to verify the identity of each system and then a connect is established.

The connection is encrypted using extremely strong data encryption that can be anything from 128 bits up to more than 2,000 bits.

The greater the bits, the harder the encryption is to crack by hackers and the longer it would take.

Every piece of information transmitted over the internet is scrambled and then unscrambled when it reaches the VPN server. This allows for all sorts of confidential information to be transmitted safely so that even if it were to be intercepted by a digital thief, they could not read the contents.

Applications For A VPN Service

For a business, a VPN can provide a secure login for employees who are away from the office and the confines of the corporate local area network. With this high level of encryption and the need to login each time, a company’s internal network can remain secure even when it is being accessed outside by employees.

Other applications for business include being able to secure communications between different computer servers located in different parts of the country or around the world. Customer data can be transmitted safely and important company records can be sent online to the head office without the need to send them by courier.

For individuals, VPN services are now being used to appear to be located in a different country than their originating connection. This is helpful when locked out from a web site ora  subscription service only because the person is presently outside of the approved country. Security alerts that might otherwise pop up when someone is trying to log into their bank account from abroad, can be avoided when they are logging in through a server which makes them appear to be in the same country as the bank.

A VPN service is well worth considering at a cost of under $10 per month because it can provide an extra layer of digital security which is much needed in this age of rapid global communications.
