Understanding SASE Architecture
SASE, or Secure Access Service Edge, represents a significant shift in cybersecurity by integrating a cloud-based security architecture that utilizes a shared responsibility model. This new approach replaces traditional perimeter defense strategies, requiring organizations to manage a security stack that could consist of anywhere between 15 and 300 tools depending on their size. Previously, network defenders had to maintain multiple sets of tools at various locations, leading to increased management complexity and costs. SASE simplifies this by allowing a vendor to provide a centralized security stack while establishing global policies for customers, transforming how organizations can secure their networks.
The Components and Evolution of SASE
The SASE framework consists of four main components: a SASE cloud provider, the security stack, an SD-WAN, and peer connections with major content provider fiber networks. Each component contributes to optimizing security management; for instance, the SASE vendor delivers security services like zero trust and compliance, while the SD-WAN enhances routing efficiency across customer locations. The model is particularly beneficial for small and medium-sized organizations that may lack the resources of larger enterprises, granting them access to robust cybersecurity tools. As SASE continues to evolve, it currently sits at the apex of inflated expectations on Gartner's hype cycle, indicating that while interest is high, this architecture is still in its early stages before achieving full maturity.
A security architecture that incorporates the cloud shared responsibility model, a vendor provided security stack, an SD-WAN abstraction layer, and network peering with one or more of the big content providers and their associated fiber networks.
