Duo Security

Duo Security is a cybersecurity company that specializes in two-factor authentication (2FA) solutions. It helps organizations enhance their security by verifying users' identities before granting access to systems and data. When a user tries to log in, Duo often requires a second piece of information—like a text message code or a smartphone app approval—along with their password. This extra step makes it much harder for unauthorized individuals to access accounts, even if they have the password. Duo aims to protect sensitive information and ensure that only legitimate users can access critical systems.
