  • End-to-End Protection with Zero Trust Hybrid Security in the Next Gen SASE Branch
DateJun 6, 2024

Netskope’s Next Gen SASE Branch represents a groundbreaking advancement in network security and connectivity for modern, borderless enterprises. This hybrid-connected, secure, and automated solution merges several key components: Context-Aware SASE Fabric, Zero Trust Hybrid Security, and SkopeAI-powered Cloud Orchestrator. By unifying these elements into a single cloud offering, it provides a modernized branch experience with a robust set of features.

At its core, Netskope’s solution integrates cloud-based Secure Web Gateway (SWG), Cloud Access Security Broker (CASB), and on-premises security measures like Intrusion Prevention System (IPS) and Application Firewall. This combination ensures comprehensive security across all facets of an enterprise’s network, addressing both on-premises and cloud environments seamlessly.

The Netskope ZTNA Next extends beyond traditional security measures by combining Software-Defined Wide Area Network (SD-WAN) and Zero Trust Network Access (ZTNA) capabilities, effectively replacing legacy VPN systems with a singular, more efficient agent. Additionally, the integration of device intelligence within the Netskope SASE gateway ensures real-time threat detection and dynamic microsegmentation, preventing lateral threat movements.

The architecture supporting this solution is both sophisticated and robust. It includes:

Netskope One Gateway**: Manages data traffic securelyNetskope One Client**: Facilitates secure connections for end-usersNetskope SASE Orchestrator and Controller**: Manages the control and management planes, ensuring secure and efficient network operationsNetskope New Edge**: A cloud-native platform offering high-speed, reliable service across a wide geographic area.

The SASE Controller plays a pivotal role, managing the control plane functions such as BGP route reflection and device information distribution through secure IPsec overlay tunnels. The SASE Orchestrator oversees SD-WAN management, device configuration, monitoring, and telemetry. Communication within the system is fortified with secure protocols, including TLS 1.2 and TCP 4500, ensuring data integrity and protection against replay attacks.

Netskope’s Borderless SD-WAN, a fundamental component of this architecture, undergoes regular vulnerability scans and penetration tests, guaranteeing compliance and security. This SD-WAN overlay provides enhanced data integrity and replay protection through sophisticated mechanisms like Authentication Header (AH) values and IPsec ESP protocols.

Central to the solution is its hybrid security model, which includes both on-premises and cloud-delivered security services. On-premises features encompass a stateful application firewall and IPS/IDS, while cloud security is seamlessly integrated with Netskope’s global NewEdge data centers.

Netskope’s approach to network segmentation simplifies compliance, enhances security, and reduces congestion by segregating routing information on a per-segment basis. This segmentation is managed through the SASE Controller, allowing for precise policy-driven management.

The cloud-native, multi-tenant architecture of Netskope’s Borderless SD-WAN supports hierarchical role structures and integrates with Identity Access Management (IAM) systems like Azure and Okta. This facilitates streamlined role-based access control (RBAC) for service providers and enterprises.

Netskope’s Next Gen SASE Branch enables secure, end-to-end segmentation, hybrid security, and comprehensive role-based management, making it a robust solution for modern enterprises aiming to enhance their network security and operational efficiency.
