Acknowledging that security and convenience are inversely proportional I like the products from this company, they specialize in cash/bank/legal document protection bags that are easy to use without taking additional effort. https://arifkin.com/ https://arifkin.com/ A locking briefcase (a cylinder key lock with 7 pins? - not sure of the correct terminology here)) may not stop an expert locksmith, but otherwise you can tell if the contents have been accessed. I have a fabric one (heavy duty fabric, cannot be torn by hand) with a zipper that is locked by key. I keep my notebook computer in it when I travel, either in the trunk of my car or my hotel room. Or, when I took a multi-day train trip a few years ago, every time I had to leave my "roomette" (open access) and travel a few train cars away for a meal or sightseeing, I made sure the laptop was in the locked briefcase.
