Security Advisories


Arista Networks is committed to maintaining the highest standards of security across our product portfolio. Leveraging extensive testing and monitoring of vulnerabilities to isolate and neutralize threats early, Arista's Product Security Incident Response Team (PSIRT) provides global coverage for public reporting of possible security vulnerabilities across the product portfolio.

The PSIRT team monitors industry-wide vulnerability reporting as well as providing a single point of contact for customers and interested third parties to investigate and identify potential threats. The PSIRT team also works to communicate these issues back to the user community in a timely manner.

Arista PSIRT is happy to work with researchers on discovered vulnerabilities in Arista products, the assignment of CVEs, and timelines for responsible disclosure. If a researcher discovers a new vulnerability they will be acknowledged in the advisory related to the vulnerability. Arista PSIRT is interested in receiving reports on issues affecting features in both Arista code as well as Open Source Software used in Arista products. Security issues found in Open Source Software which do not affect Arista products are out of the scope of Arista and should be referred to the appropriate CNA found here.
