You could use services like browserstack.com or you could set up a staging server, mentioned before, and test via VM’s or from your local device lab or collect devices your self. Get a really cheap second hand laptop, install whatever you need and go nuts.

Also dual booting is so old school :)

Not sure what you mean by security of VM’s.
