“Safe area” guild buff

Could we have a safe area guild buff? I think this would be really helpful and promote building and activities on higher tier planets.

In a nut shell; this buff would prevent mobs from attacking spawning, entering, or attacking within the area of the buff while it’s active. I’d suggest a level 1 buff covers the area of that guild settlement, a level 2 gives you the settlement plus 2 plots around the perimeter, and the level 3 gives you 4 or 6 plots outside the guild settlement perimeter.
