Guristas controlled space

Hello here =)

I think you already saw my (dumb) questions in that topic, so here’s a new one !
I recently put my feets in a NPC Null-Sec space, controlled by the Guristas. I found that they have stations floating around the moons of those pockets and I would like to know : can I count them as “safe point” ?
Because of course my standing toward that Pirate Faction is really low (I was still able to dock at the station), but when I undocked a large group of NPC jumped on my position (cruisers and BS, didn’t catched me tho).

Also a second one : the sentry guns guarding the station had a icon in darker blue than the one we can found in the other parts of space, anyone can answer that please ?

Thanks in advance =)
