In GGmod, I've been experimenting with impenetrable sector cloaking warppoints.
Ideally ships which end turn on the warppoint will be moved to a random neighbouring hex, but for now, I'm just throwing damage because it is simpler to script.

Defending a warppoint typically means defending the 3-5 sectors around it, or maintaining a mobile defense fleet close enough nearby to intercept enemy fleets.
Plus a few very fast interceptors to pick off the enemy sensor scouts, of course, since they can easily outrun your warships.
