Opticca Security SASE (Secure Access Service Edge) is a cloud-native, globally distributed network security architecture that converges networking and security capabilities into a single software stack. The solution shifts the security model from traffic-flow-centric to identity-centric, authenticating and applying security policies on a per-transaction basis while granting least-privilege access only. Key functional areas include: - Zero Trust Network Access (ZTNA): Assumes a hostile network environment, enforcing authentication of all devices and users, verifying locations, and checking policy compliance before permitting sessions. - Secure Remote & Mobile Access: Delivers security directly to the user, eliminating the need to backhaul traffic to a centralized policy enforcement point. - Centralized Orchestration: Provides centralized policy definition combined with local enforcement and role-based management. - Direct Internet Access (DIA) Security: Secures and optimizes user access to cloud resources and applications. - Threat Prevention: Implements application and resource cloaking, network segmentation, and isolation using distributed control and data planes. SASE replaces appliance sprawl with a unified software stack, reducing both capital (CAPex) and operational (OPex) expenditures. It supports work-from-anywhere (WFA) scenarios, SaaS adoption, and multicloud environments by applying consistent security policy regardless of user, device, application, or data location.
