I have a Web App that's supposed to be used only within a Teams Tab. It's a simple app with a bunch of html pages and since it uses SSO for authentication I don't have any explicit login screens. I don't want anyone to access the app from outside of Teams. If anyone tries to access any of the app's web pages outside of Teams, it should throw an error or a warning. Currently the whole world is able to load the every html page of the app from outside Teams. Is there an easy way to prevent this?

Presumably you're referencing the Teams JS library in your tabs. Inside of this there's a "getContext" method which will only work inside of Teams, and it has a callback, so you could perform your final page rendering inside of that callback, something like:
microsoftTeams.getContext(function(context) { document.getElementById("MainPanel").style.display = ""; })
where you have display set by default to "none", as an example
