CionSystems Cion MFA is a multi-factor authentication solution designed to protect Windows-based machines — including desktops, laptops, servers, tablets, and virtual systems — in both enterprise and cloud environments. The solution adds a second layer of verification beyond a username and password, requiring users to present an additional factor before gaining access. This applies to both local and remote logins. Supported authentication factors include: - USB token: Any standard USB flash drive can be provisioned as a physical unlock key, providing protection against phishing without requiring specialized hardware. - SMS OTP: A one-time password is delivered to the user's registered mobile phone via text message. - Email OTP: A one-time password is sent to the user's registered email address. - Challenge-response questions: Users answer pre-configured security questions to verify identity. The product addresses common attack vectors such as brute force, keylogger, man-in-the-middle (MITM), and phishing attacks that exploit compromised credentials. It targets the credential-based attack vector, which the vendor notes accounts for over 80% of breaches. MFA functionality is also noted as being integrated into CionSystems' Cloud SSO product. The product received a Global Infosec Award in 2021 from Cyber Defense Magazine.
