Depends on whether the IP claims are valid. ERNW isn't saying anything about being provided IP by FireEye, which also sounds unlikely. And what IP could it be? Going from US law, none of trademark (they aren't pretending to be FireEye), trade secret (if FireEye revealed any without NDAs etc. they no longer are), or patents (publicly disclosed, their reason for existence in the US at least) would seem to apply. If they got source code, this would be going rather differently. Maybe reverse engineering law is different in Germany? Or ... well, let me just say I wouldn't be inclined to buy anything from the company after looking at that picture of the CEO, I've seen and interacted with that type way too many times.
