IssueError message "Your browser is not supported" displayed in RSA Security Analytics for Internet Explorer 10 and above.
Error message: "Your browser is not supported"

Cause 1: IE 10 and higher rearranged the order of objects in its User-Agent header, which prevents Security Analytics from properly identifying the browser type/version.

Cause 2: Disabling DOM Storage capabilities in the viewing browser will trigger this error. This is also sometimes referred to by the names "JavaScript storage," "LocalStorage" (Google Chrome), "local storage," and others.

Support for IE11 has been added as of Security Analytics 10.2.3 and 10.3.2.


Cause 1: If upgrading to a more recent RSA Security Analytics release is not possible and an alternate browser cannot be used due to customer policy restrictions, the "allowUnsupported" parameter may be passed to the login screen (for example, https://<SAserver-IP>/login?allowUnsupported) to access Security Analytics with the current browser. Using this workaround will not eliminate the "unsupported browser" message. It will only allow the message to be closed. The user may log in normally when the message has been closed.


Cause 2: If support for DOM Storage is disabled, please re-enable it to enable proper function of the RSA Security Analytics user interface.
  • Internet Explorer: DOM Storage is normally enabled or disabled via the "Internet options" menu, under the "Advanced" tab. It can also be disabled via Group Policy. If you cannot change this setting, or this setting has no effect, contact your system administrator.
  • Mozilla FireFox: DOM Storage is controlled via Options/Preferences -> Advanced -> Network, under the heading "Offline Web Content and User Data". It can also be enabled or disabled completely by an option that is normally hidden, called dom.storage.enabled. To view it, enter "about:config" in the URL bar ("Awesome Bar", address bar, etc.). Enter the value name into the Search box. Toggle the value if it is disabled.
  • Google Chrome and Chromium: Google Chrome does not normally offer end-user control of DOM Storage in recent releases, but it is still possible to disable it with a command-line argument, --disable-local-storage. Removing this argument depends on the operating system in use. Refer to vendor docmuentation for changing command-line arguments passed to programs. This setting may also be controlled via Group Policy on the Microsoft Windows platform. If you believe DOM Storage has been disabled via Group Policy,contact your system administrator.


If you are unsure of any of the steps above or experience any issues, contact RSA Support and quote this article ID for further assistance.

NotesUsing the "allowUnsupported" parameter may result in improper rendering of the page.
