Plexi aims to make public key verification an automatic process, which is a significant leap forward compared to traditional methods like scanning QR codes or manually verifying keys. This automated system is expected to boost user trust and security substantially. As Matthew Prince, co-founder and CEO of Cloudflare, pointed out, their mission has always been to improve internet security. By leveraging the trust that millions of organizations and customers place in Cloudflare, they see their role as an external auditor for E2EE systems as a natural extension of their existing services.
