About Oneleet Oneleet is a cybersecurity startup with a mission to revolutionize the industry. It aims to make effective cybersecurity easy and painless for companies by providing a comprehensive platform that helps companies build, manage, and monitor their cybersecurity program. We’re essentially building an all-in-one security platform that will allow companies to have everything they need under one roof to build a secure company. We have already built our own ASM (Attack-Surface Monitoring), CSPM (Cloud-Security Posture Management), MDM (Mobile-Device Management) and Vulnerability Management modules, and have many more on the roadmap.
