The caches should be physically tagged (though virtually indexed). The use of a physical tag guarantees that even if you index with a a virtual address from another process's address space space, you will likely see a physical tag mismatch (unless it's a data from a page that gets mapped into all processes or something, in which case it's shared as expected).
