Cloudflare announced Tuesday that it will issue quantum-proof TLS certificates to secure web traffic against attacks from future quantum computers. [^2]

Separately, the company plans to acquire an established trusted root certificate. This acquisition will ensure certificates continue working on older smartphones, operating systems and devices that no longer receive software updates. [^1]

No implementation timeline for either initiative has been published. No purchase price for the root certificate was disclosed.
