Why you should use free WLAN networks only with VPN
That's convenient. If we want to walk through shopping streets, sit down in the next restaurant, surf in the hotel room or wait at the station, everywhere free WLAN. In many cities there is meanwhile a nearly area-wide network of free WLAN networks. Customers and tourists have the possibility to connect to these networks almost everywhere and to hunt down your data via insecure providers. What is revealed about individuals using these networks and why you should never move around in them without protection - we'll tell you!
What information does the provider see?
First and foremost, you should ask yourself the question "what data is transmitted by you when accessing a WLAN". We distinguish two things: What do you actively price and what "must" really be technical for the connection.
Data requested by the provider:
Even though most networks are freely accessible, access is often required to enter some information. Requesting e-mail, password, date of birth or telephone number for sending an access code is not uncommon. These data are of course secured. You should be aware that you are revealing an important data combination at this moment: Your e-mail and your preferred password! Of course we don't put all providers under general suspicion, but it's about sharpening your senses how openly you handle important data.
Data that require the technical connection:
Of course, connecting to a foreign network requires the transmission of certain information from your device. These are the MAC address, the IP address and the ports of your device, which are used for the data transfer. All data that can uniquely identify your device and provide information on how to get data from and to the device.
Data that you transfer through your use:
Which pages do you call up, which data volumes do you transfer, at what time do you do this? Are you downloading something, which programs do you use (e.g. e-mail or messenger services)? That's a lot of information that someone can find out while you're sitting alone in front of your device. You lose sight of this more often than you might think, even though you could get a great deal of privacy. Quite simply even!
How can you increase your protection?
At least gross negligence should be avoided. In foreign networks you should not use applications with a high security background such as online banking . Also from sites that do not use SSL encryption, it is better to keep your fingers off. It is of course beneficial to encrypt your data. How to do that? We would like to dispel the prevailing opinion that you have to be an IT expert to be able to move securely on the net. Often it is applications that can be set up with just a few clicks and within seconds. We are talking about VPN. Simply explained, you connect to a third computer when using a VPN service. This means that instead of your data, its own data is forwarded to the network. In addition, the data that you actively transfer is encrypted by this computer - so it is very unlikely that you will be able to read it. Especially in recent years, many things have been discovered in the mobile area that have greatly simplified the use of virtual private networks. A one-time quick order, setup and immediate use is very often possible within a few minutes. "No time" or "too complicated" is not an excuse! Click here for instructions!
Free WLAN Useful but not trustworthy
Of course it is tempting to use free WLAN and if you have sharpened your senses, there is nothing to be said against it. What we cannot emphasize often enough is that in 99 of the cases victims of viruses, cyber attacks or abuse were actually extremely careless and could have easily prevented it. Security on the Internet is not a phrase. With countless hours we spend on the net, a few minutes are quite adequate for security . We also do our best to support you - we promise!
