Some versions of vi support a -S option for safe mode. nvi does this for example.

Is this because you have users running under SUDO? Most vi implementation do not have safe mode (which is not completely safe because users can get around an alias
like alias vi="vi -s"). In this case consider a chroot jail, which is probably the best solution.
