Encryption in Flight

As a customer, browser‑based sessions to your ServiceNow cloud instance(s) are encrypted over the internet via Transport Layer Security (TLS) using AES‑128 or AES‑256 block ciphers. These ciphers are subject to the browser versions in use and may be influenced by your Internet proxy infrastructure.

You can also force specific cipher suites via your own browser or proxy if desired. All end‑user access to a ServiceNow instance is always automatically redirected to HTTPS if attempted over HTTP.
