DataStax Astra introduces Single Sign-On (SSO) and Bring Your Own Key (BYOK) features to enhance security for cloud databases. SSO helps reduce the chances of compromised passwords by integrating with Identity Providers like Azure Active Directory or Okta, offering central management for password security and convenience to users. BYOK allows encryption key control, ensuring data at rest is securely encrypted and enabling quick reaction in case of a breach. These features complement Astra DB's existing comprehensive list of security capabilities, aiming to provide maximum protection from unauthorized access and ensure data privacy.
