Deepnet DualShield MFA Platform vs OpenOTP Authentication Server

Deepnet DualShield MFA Platform adds two-factor and multi-factor authentication to business applications and resources. Organizations can install it on-premises or host it in a private cloud; listed environments include Android, iOS, Linux, macOS, Windows, web, API, and self-hosted. Authentication options include SMS, email and voice codes, push, OTP tokens and apps, cards, FIDO keys, biometrics, keystroke dynamics, and device-based signals. Integration methods include LDAP, RADIUS, SAML, FIDO, OATH, WS-Federation, and proprietary agents and clients. Adaptive policies evaluate context such as location, network, device, and time, and can block a request or call for stronger MFA. DualShield also provides single sign-on, identity and access management, and a portal for password changes, resets, and account unlocking. It can protect VPN and remote desktop access, operating-system logins, web and cloud services, and Outlook email. Event logs and email or SMS alerts support auditing and administration. The paid platform has pricing on request, and Deepnet offers a free trial through a request form; no trial duration is stated.
