Trust but verify...  ;-)
But how to verify?
One strategy is protection in layers.  While true Cisco makes big bucks for
big hardware
Much of the world could benefit from more modest router and filtering
 Ubiquiti Networks  makes some nice little inexpensive boxes that are open
source (linux) enough to watch.
This same  class of hardware can support VPN  for point to point security.
For many the issue is ex-filtration
of data in terabyte quantities.

Devices like the Xfinity cable routers and modems are something the
national security folk need to watch.
Phone, security, data are a trifecta of risks.  Cable modems are another
risk, they are not dumb boxes.

As others noted grain of sand size devices are no longer caps.  An
interesting class of stuff can be built into
them and test points and debug ports are obviously interesting targets.
Automated imaging can detect changes at incoming inspection but managing of
the 'gold' standard images will
demand encryption and verification (closed garden block chain?).

JTAG test chains need to have a quality cryptographic  hash and signed.
Boards need to be designed for verification.
