Authenticated SMS

Authenticated SMS (A*SMS) is a™ patented technology to enhance SMS legitimacy at scale. With this technology, organizations have an iron-clad way to prove that they are the originator of texts through the introduction and use of the keyword ID.

Scams, Spoofing and Impersonation

Businesses and political campaigns are increasingly relying on SMS messaging for critical communication with customers and constituents. Businesses use SMS for sales, service, marketing, simple notification, and two-way conversation. Political campaigns use SMS to drive awareness, donations, and get out the vote. 

As SMS has increasingly become a channel of choice for these use cases, hackers and bad actors have taken notice.  SMS is a viable attack vector.  The U.S. Federal Trade Commission calls SMS attacks a “Triple Threat.”  There is even a moniker for these attacks – Smishing – a clever combination of the phrases “SMS” and “Phishing” (coined in a McAfee blog post, 2006).
