Moat

  • Proprietary Technology
  • First Mover
  • Scale Advantages

Nortel’s moat was historically rooted in proprietary telecom and networking technology, early mover advantage, and strong scale from its carrier relationships and R&D capabilities. Over time, that moat eroded as standards shifted toward the internet/IP stack, competition intensified, and its advantages proved hard to defend in newer markets.
