Learn about the business use case and technical background of Secure Access Service Edge (SASE).

What is SASE used for?

The SASE framework can help organizations simplify their IT infrastructure, advance their threat prevention, better protect their data, implement flexible solutions, easily connect users and devices wherever they are located, and reduce total costs.

SASE also provides a Zero Trust approach to the cloud, which validates users and device access to applications anywhere in the world.SASE provides complete application session protection, whether a user is inside or outside the corporate network.

The Rise of SASE

Gartner expects that by 2023, 20% of enterprises will have adopted SWG, CASB, ZTNA and branch FWaaS from the same vendor, up from less than 5% in 2019. And by 2024, at least 40% of enterprises will have explicit strategies to adopt SASE, up from less than 1% at year-end 2018. Additionally, worldwide COVID-19 social distancing directives resulted in momentous changes in the work-from-home, video communications, and distance-learning landscapes. As a result, internet, service provider, and enterprise traffic patterns have been permanently altered. Adopting a SASE model that provides the agility and security to address these changes is key for business continuity in the era of increasing cloud and mobile adoption.

How Trends in Digital Transformation Led to SASE

The rigid network infrastructures of the past are not sufficient in today’s IT landscape where data is stored in the cloud and on various devices. Numerous trends emerged when organizations first began their digital transformation. As a result, the culmination of these trends led to the creation of Secure Access Service Edge (SASE) technology. Digital transformation trends that led to SASE include:

  • The core of your business is now the new “network,” meaning a web of interconnected peer networks
  • Applications can be hosted on your network or in the cloud, and are accessible everywhere
  • Internet connectivity have become cheap, ubiquitous, and instantly available on cellular networks
  • MPLS is no longer affordable or practical, and are often not secure
  • Business applications and data are hosted in the cloud because of the promise of flexibility, scalability, and elasticity.
  • The death-march of custom hardware has been superseded by usage-based subscription services in cloud-native virtual resources
  • An explosion of smart devices (IoT) are connected to your core network but often lack even rudimentary security features
  • Bring-Your-Own-Device (BYOD) policies are now commonplace and lack the control and visibility of traditional corporate issued devices

SASE Delivers Key Capabilities

SASE delivers attributes to address to digital transformation:

  • You have complete flexibility in where and when security services are applied when security is integral to the network fabric. Meshed traffic patterns are handled with efficiency.
  • Security is policy-driven, independent of location, and largely independent of device. This enables security services based on the user’s identity instead of an IT-controlled device, network access point (Internet, cloud, corporate, VPN) or location.
  • SASE applies security based on the communication session and can therefore take into consideration the identity of both the user and the device as well as the data context of the transaction.
  • SASE is a purely software-defined service and does not rely on any hardware appliance or location.
  • SASE can be applied at the ever-shifting, logical edge of the network (a communication session), rather than at the physical “edge” (an IT-controlled device or corporate office).
  • Many IoT devices have little to no local security capabilities. SASE, with security in the network fabric, can safely connect these devices.


What are SASE components?

SASE is an entire package of technologies that embeds security into the global fabric of the network. Major components of SASE are Software-defined WAN (SD-WAN), Cloud Access Security Broker (CASB), NGFW and Firewall-as-a-Service (FWaaS), Zero Trust Network Access (ZTNA), and Secure Web Gateways (SWG). 

What is SASE architecture?

The core of SASE architecture is comprised of the users, devices, applications, and resources, and the identity, risks, roles, profiles, privileges and policies that govern access between them. SASE architecture is the convergence and inversion of both network and security architectures. 

How do you adopt SASE?

SASE encompasses a combination of networking and security technologies. Some experts expect enterprise to adopt a hybrid approach to SASE: using existing security and networking systems, while gradually implementing SASE technology to scale large numbers of unmanaged devices, WFA users, and cloud-hosted resources. 

What are the challenges with SASE?

As with the adoption of any new technologies, SASE can come with bumps on the road. Some points to consider when evaluating SASE are the scalability of the SASE architecture proposed, distribution of cloud gateways, SASE vendor skillset, and integration and interoperability of the SASE solution. Choosing the right SASE strategy can ease the path of a successful implementation. 

Why is SASE necessary?

SASE is necessary for today’s modern client-to-cloud era, enabling effective cloud adoption and digital transformation, consistent cloud performance for WFA and mobile users, ubiquitous policy enforcement across your network, securing unmanaged devices, sophisticated and up to date threat intelligence, and simplifying IT management. 

Who should use SASE?

Organizations large and small benefit from SASE because it is cloud-native, simple, and secure. SASE enabled organizations can enable secure and reliable Work-from-Anywhere (WFA) environments and secure access while maintaining their rate of cloud adoption. 

What are the benefits of SASE?

SASE provides many benefits by consolidating networking and security functions traditionally delivered as point products. Benefits include reducing costs and complexity, achieving a least-privileged model, ensuring consistent policy enforcement, reducing the overall attack surface, and delivering a seamless user experience. 

What problems does SASE solve?

SASE can help your organization in many ways from solving problems with traditional WAN architectures, presenting new digital transformation opportunities for your business, to increasing IT staff effectiveness. Other benefits include: reducing costs and IT complexity, securing remote and mobile users, ensuring consistent policy throughout your network, and optimizing network performance and user experience.
