NTLM (NT LAN Manager) is a Microsoft authentication protocol used for Windows-based systems. Its challenge-response authentication mechanism is primarily used for:
  • SharePoint
  • Exchange
  • Internal corporate APIs
Unlike basic authentication, which has a less secure protection layer, NTLM has multiple handshake steps and offers more robust security.
