Implement a zero-trust access framework for all applications, both legacy and contemporary, utilizing robust identity and context-driven access controls that scale effectively. Validate the zero-trust model through detailed contextual assessments, ensuring that each application access request is thoroughly secured. Enhance application access by adopting a meticulous strategy for user authentication and authorization that allows for context-aware and identity-based access on a per-request basis. By integrating with current single sign-on (SSO) and identity federation systems, users can seamlessly log into all business applications using a single set of credentials, regardless of SAML compatibility. Additionally, incorporate social login features to streamline authorization from reputable third-party identity providers such as Google, LinkedIn, Okta, and Azure AD. Utilize third-party User and Entity Behavior Analytics (UEBA) and risk assessment tools through REST APIs to strengthen policy-driven access controls with the help of the API connector for enhanced security measures. BIG-IP APM is offered across various business models, including perpetual licenses, subscription plans, public cloud marketplaces, and enterprise licensing agreements, ensuring flexibility for different organizational needs. This comprehensive approach not only fortifies security but also improves user experience by simplifying access protocols across diverse platforms.
