Many security updates do not require to rebuild the whole os. Maybe you
need to rebuild and reinstall the kernel, which takes much less time and
can be done while the server is in normal operation. Sometimes only some
specific utility or daemon needs to be updated; here it is sufficient to
just restart the daemon.

If a full rebuild is required, you can split "make world" and still do the
time-consuming "make buildworld" in normal multi-user mode; downtime is
than limited to the "make installworld" process which needs much less

If your harddisk is too small, you can make kernel and world on a
different system, export /usr/src and /usr/obj via NFS and mount them on
your server to install kernel and world.

But you're true, you need the whole source code if you want security.
