Benefits using JonDonym

It is possible to harm you in manifold ways using the data you left behind while using the Internet. The Benefits describe specific risks, which the IP-anonymization provided by JonDonym is protecting you against.

If you have made own experiences how JonDonym has helped yourself, please help us, too, and write us. For every submission which is published here you will get a JonDonym-couponcode worth of 500 MB for free.


All that your IP-address is revealing!

Every web site can find out the following about you using your Internet-connection:

  • Your current whereabouts

The country and the city/region where you are. With the help of data bases free of charge or with costs even districts and office buildings can be identified. This is called geolocation.

  • Your Internet-provider

Personal data can be retrieved using your provider.

  • Your access technology

With the help of data bases one can find out whether you are using, for instance, DSL, a modem or a mobile in order to surf the Web.

  • Your company / your authority

In case you are surfing from within the network of a company or an authority its name can be find out.

  • How long your computer is running

This is possible due to the analysis of so-called TCP-timestamps which makes even your computer identifiable.

Using a little test on our web site you may have a look at some of these information about yourself.


Data thieves see your plaintext

If you are using a wireless network in an Internet-cafe, on an airport or a railway station other users and the provider of this wireless network can observe you: they see which web sites you are visiting and which data you are putting into them. They are even able to manipulate and redirect your access to web sites.

  • Password- and identity-theft

If your are using unsecured Internet-shops your password, account information and address can be read out. Now, a third party would be able to order things in the Internet-shop using your data, as well. Besides, your e-mail-passwords could be intercepted and then your conversation by e-mail could be read along, until you are changing your passwords again.

  • Loss of confidential information

Your private messages can be intercepted and, later on, be used against you or your company. Are you writing a message to your wife and afterwards to your mistress? Are you sending business documents to a colleague which outsiders are not allowed to get?

  • Anonymous proxies do not protect you but steal your data

In the Internet there are a myriad of proxy-services both for free and with costs which promise anonymity. But: In most cases these services do not even encrypt your data against other parties' access. Additionally, it is assumed that many of them are running on cracked computers and are controlled by criminals in order to spy on the users' data purposefully.


Competitors identify the actions of your company

Most of the companies and organizations are identifiable unambiguously by means of their IP-address. Competitors can make use of that.

  • Investigations using the Internet do not remain confidentially

Your investigations on web sites which are directly or indirectly controlled by your competitors (e.g. due to a service contract) do not remain confidentially. Thus, searching the Internet it can happen that you give away business secrets unnoticed, for instance while you are looking for patents or making a market analysis.

  • Web sites of your competitors "are playing around" with you

Employees of competitors are able to observe your IP-address while you are visiting the web sites of them. Because of that they may present wrong or no information at all to you. They are even able to show a special career-page in order to headhunt your employees. You might also get an advertisement call or advertisement e-mails.

  • Spies in the industry may redirect the data traffic of your company to their own servers

Technically experienced spies are perhaps able to redirect your whole network traffic from your provider to their own servers. As a result your whole Internet communication would be uncovered. That is how all unencrypted messages and all Internet services, which were contacted by your company, would be known by your competitors.


Prohibiting free information

Besides direct Internet censorship, which is aimed at prohibiting access to specific web sites technically, there is a indirect censorship as well: the fear of suffering disadvantages just because one is consuming unpleasant contents.

  • Journalists are not able to inform themselves freely

Internet-censorship is impeding free journalism. In the scope of investigations journalists must be able to access censored contents as well, because they have to judge whether these contents are relevant to the public or not.

  • Citizens are not able to form their own opinions

In the real world there is usually not only one single truth - but many. Due to direct censorship or fear of reprisals citizens full of age are not able to get all the necessary information in order to judge the facts properly.

  • Just retrieving unpleasant contents is punished

The "Operation Himmel" (operation heaven) was praised in Germany as a big success of the investigators: But just a few of the suspects were actually guilty and the short clicking on web sites destroyed the social existence of innocents.

  • Anti-censorship-services are selling your data

Beware of anti-censorship-services: There are some which are collecting and selling your data: probably even to censors!


Work of secret service is endangered

Although the range of IP-addresses belonging to the secret service are kept secret, it sometimes happens that all or just a part of it comes to the public.

  • Mistakes made by employees unmask secret net-structures

Employees of the German Intelligence Service (BND) have already unmasked themselves on our web sites due to the fact that their browser contained a referrer to internal BND-sites. Now, we just could have saved the corresponding IP-addresses (something we have not done as a matter of principle), and the range of BND-IP-addresses (or that of the Federal Crime Police Office (BKA) because its proxy was used in some cases) could have been analyzed step by step.

  • Staying in contact in a hostile environment is dangerous

If employees of a secret service want to contact computers in their head quarters, this communication can be intercepted. And if, furthermore, the contacted IP-address is known as one belonging to the secret service, the employee is unmasked.

  • Proxy-services can be operated by your enemy

Proxy- or VPN-services which are controlled centrally can be operated by an enemy of a secret service. It is quite conceivable that secret services are deploying such computers under false names in order to eavesdrop on the data traffic of employees belonging to other secret services and that feel themselves save using these proxies. This is quite a inexpensive opportunity of espionage. Probably, one can even earn some money setting up a commercial service which is faked using this proxy/VPN-service.
