About BlackBerry

5. Advanced Security: BlackBerry supports an industry-leading security standard called Triple DES (Data Encryption Standard) to meet corporate security requirements for remote email access. Since Triple DES is considered unbreakable, you can feel confident about sending and receiving confidential information wherever you go.
