Fastblue Blog Insights from our team to yours Transform Business with Secure Access Service Edge (SASE)
Secure Access Service Edge (SASE) is a newly defined technology category that delivers seamless, secure access to critical resources across the enterprise for all workers, devices, and locations. This article looks at the convergence of network and security functions..
Demands
New Normal, New Demands
The steady, ongoing move toward cloud-based applications and services combined with the sudden upheaval into an entirely remote workforce confronts organizations with changes and challenges not previously considered by traditional network design and security strategies. Some of these changes include:
- The WAN Edge has gained importance over the central data center, compelling IT leaders to work from the edge in, rather than from the core data center out.
- Security has also followed this trend, shifting from the data center to the WAN Edge and cloud resources.
- Integration between SD-WAN and Cloud Based Security has brought an integration of network, security, and ongoing management.

New Solutions
SASE is the convergence of comprehensive network and security capabilities to support secure access across digital enterprises. As a cloud-native service, SASE provides consistent and effective policy management from a centralized platform to help respond to digital business changes. For example, a SASE platform consolidates WAN/SD-WAN features with Firewall as a Service, Zero Trust Network Access and Cloud Access Security Broker into a unified service.

The 3 core features of SASE architecture are:
Cloud-native service
– SASE is cloud-based, cloud-managed, and delivered to enterprises as a service by a single provider. This model helps organizations transition from multiple vendors and hardware to a single vendor, which increases control and visibility across the network.
Identity-based, Zero Trust security
– SASE takes a Zero Trust approach to security ensuring that no endpoint device is inherently trusted on the network. Security integrates with the network to provide identity and context aware policies across all traffic. With centralized policies and protection at all points of contact, SASE helps companies protect their assets from the edge to the cloud and core.
Edge-based, globally distributed POPs
– SASE solutions utilize global POPs that integrate network and security policies, providing end users with reduced latency and distributed security scrubbing centers to push security updates from the edge.

Work Better with SASE
SASE architecture overcomes both legacy and 2020 challenges to enterprise networking. The cloud-based service delivers solutions that improve security and lower costs, enhancing network performance and access for all enterprise resources. SASE lets organizations work better with:
Reduced network & security complexity
– Companies can reduce the need for best-of-breed point solutions by integrating them into a single vendor. Rather than security and network teams working through multiple systems, organizations can operate with a single provider for unified management, which enhances monitoring, visibility, and analytics.
Stronger security management
– SASE enables globally distributed content inspection though a single policy. Updates are pushed to the edge quickly and securely with edge-based global POPs, blocking new threats as they emerge without the rollouts of new deployments.
Cost savings
– By supporting more capabilities, SASE allows organizations to engage with fewer hardware and software vendors, which reduces individual service purchases.

Succeed
Because it solves important IT challenges, SASE is experiencing both hype and rapid growth. For example, this new, cloud-native, as-a-Service model enables transformation from centralized data center security to edge-based software-as-a-service (SaaS). Rapid SaaS expansion has led to the adoption of service-delivered security products (SecaaS), which focus from the edge to the core. SASE promises to meet this need through the convergence of security and network.
