I'm a UX designer and I work on several enterprise level applications at my current job, but I don't have clearance to share any detail about them. Nobody has. Although the applications are available publicly behind pay-wall/trial-wall, the employers don't want employees to showcase those in their portfolios. On the other hand, all the new jobs I have applied to are keen on seeing "real-world" projects. What I can show them as my portfolio (because I can't show the things I work on)?
