Gemini is a global crypto and Web3 platform founded by Cameron and Tyler Winklevoss in 2014, offering a wide range of simple, reliable, and secure crypto products and services to individuals and institutions in over 70 countries. Our mission is to unlock the next era of financial, creative, and personal freedom by providing trusted access to the decentralized future. We envision a world where crypto reshapes the global financial system, internet, and money to create greater choice, independence, and opportunity for all - bridging traditional finance with the emerging cryptoeconomy in a way that is more open, fair, and secure. As a publicly traded company, Gemini is poised to accelerate this vision with greater scale, reach, and impact., Gemini operates at the intersection of financial services and emerging technology where the consequences of security failure are measured in customer trust and regulatory standing. The Application Security (AppSec) team exists to make sure security is never an afterthought. We are on a mission to secure products at the time of thought and the time of build: at the product requirements doc, the technical architectural decision, at the line of code. We believe that security input is most valuable before the work is done and after-the-fact is too late and too expensive.
