See why teams trust us

Yeeth Security helped us enhance the security framework of the Open VSX Registry. Their work introduced pre-publish checks, quarantine workflows, and threat-informed detection mechanisms that significantly strengthen the platform's security while keeping the publishing process straightforward for extension publishers.
