SASE Interconnect Platform for Context-Based Traffic Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing SASE environments face challenges in efficiently integrating with various network fabrics, including mobile/cellular networks, IoT, and Wi-Fi, for secure traffic processing and management, particularly in connecting service provider networks to SASE environments, and relying on cloud computing providers for egress traffic leads to high costs and latency.
Innovation Solution
A SASE interconnect platform solution that supports both IPsec and non-IPsec traffic, integrates with service provider networks, and applies context-based security using intelligent security platforms like Palo Alto Networks' Prisma Access Secure Service Edge, enabling deep packet inspection and policy enforcement based on subscriber and device context information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If SASE environments rely on cloud computing providers for egress traffic, then security processing is simplified, but costs and latency increase
Solution Approach 1:
The patent segments the SASE architecture by introducing local egress points through service provider network integration. Instead of funneling all egress traffic through centralized cloud providers, the system divides traffic paths into cloud-bound and local egress routes, allowing security processing to remain simplified while reducing latency for local traffic through direct service provider network egress.
2Adaptability or versatility
If SASE environments integrate with diverse network fabrics, then network compatibility improves, but integration complexity increases
Solution Approach 1:
The patent implements a universal service provider network interface that handles multiple network fabric types (mobile/cellular, IoT, Wi-Fi) through a single integrated architecture. This multi-functional interface consolidates diverse integration requirements into unified protocols and procedures, improving network compatibility while reducing integration complexity by eliminating the need for separate integration paths for each network type.
3Measurement precision
If deep packet inspection is applied to all traffic, then security detection accuracy improves, but processing overhead increases
Solution Approach 1:
The patent applies local quality by implementing context-based security policies that dynamically adjust inspection depth according to traffic characteristics, subscriber profiles, and threat levels. Instead of uniformly applying deep packet inspection to all traffic, the system tailors inspection intensity to specific local conditions, thereby maintaining high security detection accuracy for suspicious traffic while reducing processing overhead for trusted or low-risk traffic flows.

AI summary
Techniques for providing security for providing a Secure Access Service Edge (SASE) Interconnect Platform are disclosed. In some embodiments, a system, process, and/or computer program product for a SASE Interconnect Platform includes receiving ingress Service Provider (SP) data plane traffic for a tenant from an SP backbone to a SASE cloud network for security processing via an Interconnect that is configured for a compute region and an IP block and an Autonomous System Number (ASN) to advertise the IP block in Border Gateway Protocol (BGP); extracting contextual information associated with the SP data plane traffic to determine a security policy to apply to the SP data plane traffic; enforcing the security policy on the SP data plane traffic to provide secured SP data plane traffic using a Security Processing Node (SPN); and egressing the secured SP data plane traffic back to the SP backbone or to an external network.
