Hsinchu, Taiwan, February 19, 2024 – Zyxel Communications, an industry-leading provider of secure broadband networking, internet access, and connected home products, today announced it has become the world’s only networking brand* recognized at the elite Provider Acceptance Level by the U.S. government’s National Vulnerability Database (NVD), alongside industry leaders such as Adobe, Lenovo, and Siemens.

“This trust placed in us is a testament to Zyxel’s commitment to providing accurate and trustworthy vulnerability data, so our customers can benefit from the highest standards of product security and transparency,” said Edward Yu, Zyxel Group’s Chief Information Security Officer. “It’s also indicative of the trust we’ve built among our customers and across the networking community with our thorough and proactive approach to identifying, reporting, and addressing potential threats.”

Data submitted by CNAs is ranked on its percentage of agreement with the NVD's own assessments. Achieving the elite Provider Acceptance Level requires a CNA's data to be consistently accepted at least 95% of the time.


Of all 355 CNAs worldwide, Zyxel is one of only ten to have achieved the Provider Acceptance Level for both the CVSS v3.1 severity assessment standards and the CWE vulnerability classification system. The Provider ranking comes less than two years after Zyxel became a CNA. “This couldn’t have been achieved by the Product Security Incident Response Team (PSIRT) alone,” Yu said. “The real MVPs here are the product teams and the security community that work with our PSIRT to do whatever necessary to ensure users stay up to date and safe.”

*The acceptance level data were accurate as of February 1, 2024.
