The U.S. engineered Sub Rosa® Pro secure web browser supports web site access from an Android phone or tablet with strong, two-factor authentication using a CAC, PIV, or derived credentials. Sub Rosa Pro is the only mobile browser available that allows you to sign/encrypt/decrypt email through Outlook Web Access (OWA). New features in v4 also give you full access to your OWA calendar, allowing you to view, create, and respond to calendar events. Sub Rosa Pro is FIPS 140-2 validated and approved under DISA's DoD Mobile App Store. The browser also acts as an authentication agent, smoothly coordinating reader and card access to an optional secure app ecosystem.

The Sub Rosa Pro license will work with any reader that appears as a CCID device, such as the Thursby readers . U.S. phone and email technical support is included for individual users at no additional cost.
