In 2012, CloudFlare was approached by a major bank seeking assistance with DDoS attacks that were overwhelming their on-premise network hardware solutions. The challenge was to provide a cloud-based solution without compromising the security of SSL keys. After extensive research and development, CloudFlare introduced Keyless SSL™, which allows organizations to maintain control over their private SSL keys while leveraging the scalability and flexibility of the cloud. This innovative technology has been praised by security experts and financial institutions for enhancing security and trust in content delivery networks.
