For the last year Admiral Sarnow has been working on further upgrading the orbital defences, with the aim of bring them up to the level that Deiphobe currently has. This will be enough to make all but the most powerful of fleets struggle to destroy them, allowing you to either keep control of some of the orbitals in case of invasion or halt attackers in the void.
