Yea, my bad, but even a small Carrier task force can do miracles, while your capitals might struggle against enemy fighters on their own.
Right now, i´ve just invaded the "Xenon Sector", and while i have way more, and superb, ships to my disposal, there is one trick how to keep Xenon Behemots ( I, K, Z ) at bay - use Ion Cannons. Boron Sturgeon would be ideal for this, thogh, you better fly it yourself to stop it from turning around like a wounded rat, or use Adv. Fight Scripts + activate it for cap. ships in the settings.
At this point I'm just cheating out the fleets. If they normally fly from the Xenon Relay to Solitas, they get intercepted by two Boron sectors, so at worst a fighter wing or a few corvettes get through. The problem is that they aren't doing this. The game sees "Unknown Sector" and decides that it's fair game for spawning. So twice now I've watched, in sector, a fleet of the following:
One Xenon K
2-5 Xenon L's
2-4 Xenon P's or PX's
One Xenon C or G (god forbid)
Usually at least one Xenon M3 bomber (X, I believe)
You can "cheat" more efficiently, if you install "Ring of Fire" script, using tonns of stealth LT´s, at least that would handle the problem untill you get a proper answer to your "Xenon menace".
Also, SEWN might help identify the Xenon earlier.
But i think you are mistaken here a bit; Xenon Relay 481 lies 2 sectorps apart from Solitas, but there are 1 Paranid, and 1 Boron sectors in the way. And none of them is a core sector, iirc, so don´t expect them beeing intercepted by any significant Commonwealth force. You could place sats in those sectors and monitor Xenon trek ( easy with SEWN ).
All I have to my name so far is a Complex slowly building some cash, a few UT's (lost one up and comer to a pirate attack sector trading in The Wall, of all places), and my personal M7 Talon overtuned (which can now handle almost any ship one on one if I can split the ships apart from each other)
Well, i prefer to make my first big money by boarding M6, and then switching to M7 ( i use Improved Boarding, so if you don´t you could try it with Brig/Galeon/Carrack since they can fire boarding pods - just an idea for a quick money/additional ships for your forces ).
But: those Xenon are just migrating, and you could simply let them pass beein OOS, i used to have those problems all the time while settling in a US next to Redemption. Only IS they will go after your personal ship, and ones bombers are present, they´ll hit any of your assets. But your complex is probably build at least 30km away from any jumpgate, so it won´t be harmed.
It's become a common occurrence for the Xenon to just spawn by the North gate. Pirates come all the time, but they come through the South gate (thanks to Tempestine), but I keep a small OWP there to handle them. There's also the occasional Khaak cluster / transport, but again, the OWP can handle them. It's when a full on Xenon fleet decides to spawn in the sector is fair game. Would the Sector Takeover script alleviate that?
AFAIK, those Xenon fleets don´t spawn, but migrate from their sectors. The reason you feel they are spawned might be that you think they can´t get past two boarder sectors of Paranid/Boron; but you could find it out by using Sattelite Early Warning Network ( aka SEWN ).
The take over scripts would only affect the native Xenon sectors by not preventing the spawning of genuine Xenon/actively spawning them to recapture the sector ( STO has those features available ). Not sure about Laz. Corp. one, though, but don´t really think it does ( there would be info bout that in the topic, and/or reports from users ).
Good luck
