NetNumber named as an approved STI Certification Authority

LOWELL, Mass. — NetNumber announced today it has been approved by the United States STIR/SHAKEN STI Governance Authority (STI-GA) to operate as an STI Certification Authority (STI-CA). STIR/SHAKEN (Secure Telephone Identity Revisited/Secure Handling of Asserted Information Using Tokens) allows communication service providers (CSPs) to digitally sign calls from known trusted callers.

As an STI-CA, NetNumber plays a critical role in the overall STIR/SHAKEN ecosystem, issuing SHAKEN certificates to CSPs that have been vetted by the STI Policy Administrator (STI-PA). These certificates are used by the CSPs to authenticate and verify the caller ID presented with incoming calls. This step makes more difficult the CLI spoofing that features prominently in the deluge of fraudulent robocalls that US consumers receive daily.

“The STI-Governance Authority Board is pleased to welcome NetNumber as an STI-Certificate Authority in the SHAKEN ecocsytem,” said Linda Vandeloop, STI-Governance Authority Board Chair.

“STIR/SHAKEN is critical to restoring trust in the telephone system,” explained Steve Legge, chief operating officer, NetNumber. “Nearly 90% of U.S. consumers reject or ignore calls from unknown numbers. For several years, NetNumber has been at the forefront of delivering solutions to protect consumers from nuisance and robocalls. Today, we are proud to accept the responsibility of operating as a Certification Authority, and to help CSPs restore trust in their telephone services.”
