In this post, we’ll go over what SHAKEN/STIR is, its importance, and how to get started.

What is the problem that is being solved with SHAKEN/STIR?

Consumers don’t answer the phone anymore because the public telephone network has been flooded by Spam and robocalls. This is making it harder than ever for businesses to engage with their customers. In 2019 alone, over 50 billion robocalls in the United States eroded trust in the telephone network and led to a drop in call answer rates from unidentified numbers! SHAKEN/STIR is here to combat this problem.

What is SHAKEN/STIR?

SHAKEN/STIR is a caller authentication framework meant to help restore trust by reducing fraudulent robocalls and illegal phone number spoofing. SHAKEN stands for Signature-based Handling of Asserted information using toKENs, and STIR stands for Secure Telephone Identity Revisited. They are standards developed by ATIS and the IETF respectively.
