To implement any organizations internet access rules, filtering and censorship on internet access are properly defined by administrators. This forbid access to non business related sites.

If you are using Firefox as your web browser then you need to download the firefox add-on. The UltraSurf adds a golden lock near the task bar. You can hide this also by selecting the “Hide Golden Lock” option from the Options window. There are many option available to configure.
