Yeah, my characters power is Technomancy, so he can seize control of opponents technology or learn what it can do, in a process of > basic function/very close proximity effect (which is how he blocks its ability to sense his internals.) > Greater function > Minor control > Complete knowledge > Complete controlThat's just the fairest way to put what I essentially said was taking control of technology into a tier system, the first tier will be accessed in my first post (where I'll also explain how he's able to block the scanning.) I'm asking what degree my character can sense your tech (or what defenses it has from his Technomancy.)

I imagine he can sense it just fine, if/when he can pick it out from the other signals seeing as we are surrounded by Mystan tech, but it is very alien. But I'm not all together sure how you 'sense' tech, since it's not based on a real world equivalent from what I can gather, so honesty I can't answer that question completely. Shenestra for her part is using IR, Magnetic wave imaging, and thermal to name a few.

As for defenses all her gears functions are controlled primarily by a slaved spirit which is pretty much also capable of hacking or building firewalls and is the primary defense against such hostile take over. Which it does seamlessly freeing up Shenestra mind to do other things, like stabbing. But allot of her gear is surgically grafted into her secondary neural network, allowing mental interface, which is a second level of defense in of itself. 

I imagine it would devolve into some giant unseen war of fire walls, viruses, worms, and subterfuge. But again, I'm not sure how your 'takeover' works, but I imagine u using the medium of his soul for it, so it stands to reason another spirit can block it.
