What Makes Us Special
Were not just a highly ambitious, large-scale technology company. Were a highly ambitious, large-scale technology company with a soul. Fundamental to our mission to help build a better Internet is protecting the free & open Internet. In 2014, we launched Project Galileo, an initiative through which we partner with global NGOs to identify websites at risk of attack & provide the same state-of-the-art mitigation technology already used by Cloudflares enterprise customers--at no cost. Project Galileo equips politically & artistically important organizations & journalists with powerful tools to defend themselves against attacks that would otherwise censor their work.
Cloudflare hires the best people based on an evaluation of their abilities & effectiveness. We don't discriminate against employees on the basis of any other personal characteristic or any classification protected by federal, state or local law.
