Fluid is a site specific browser for OS X. It allows you to make desktop applications out of web pages. For example, GMail, GCal and GDocs are generally the first applications people tend to “Fluidize”. Indeed, I have created a single Fluid application for my company’s office applications.

But Fluid provides another benefit that I think gets less coverage than it deserves; security. By creating a site specific instance of your web application you minimize some of the common web attacks that are in the wild such as Cross Site Scripting (XSS) and Cross Zone Scripting.  By limiting your fluidized web application to a very narrow domain path you can prevent any nefarious web pages from opening within that application.

Links that point to pages (or scripts) from a different domain will open in your default browser, not in your Fluidized application. Beyond your “office applications” you might want to consider using Fluid for your banking applications.
