Re: Proof???
GCHQ did an in-depth review of Huawei kit and found nothing.
Not quite. They found no deliberate back-doors, but they did fine piss-poor coding practices and a real struggle to get repeatable builds of firmware as a result. Why have a secret back-door if your windows are open?
Flip-side is they did not review other vendors and, based on the high score CVE from Cisco, SonicWall, Fortinet, etc, they don't seem much better.
