• ◐Docs discoverablerequired2/4

  Docs URL https://vonage.com/docs exists but returned HTTP 403 — readable only behind login

Response hygiene, TLS and redirect discipline, and security contact channels agents depend on at runtime.

• ◐TLS & redirect hygienerequired1/2

  http://vonage.com/ reaches https but ends in HTTP 403: http://vonage.com/ → https://vonage.com/ → https://www.vonage.com/
