Secure Access Service Edge (SASE) is a cloud-based architectural framework that ensures secure access to corporate resources from any device or location. In simple terms, SASE is a combination of network security services and cloud-based networking that provides secure access to corporate resources irrespective of the location of the user. SASE has evolved as an architectural framework to provide a new way of delivering secure network services to organizations that are increasingly dealing with a distributed workforce and migrating to cloud-based services.
SASE is an innovative approach to network security architecture that is designed to deliver security services like zero-trust network access, firewalls, secure gateways, SSL inspection, secure web gateways, and cloud security functions as a service. SASE provides a distributed security model that allows businesses to secure their resources quickly and easily. SASE is one of the most significant technological trends in recent times, as it enables organizations to move beyond the traditional methods of network security service delivery.
SASE’s significance and need arose in response to the increase in the number of distributed workforces that are working from various locations. Businesses realized the need for a solution that could provide secure access to resources from any location, without compromising the security of the network. Thus, SASE evolved as an architectural framework that encompasses multiple security services and can be deployed over various cloud platforms, allowing organizations to leverage the security services they require for their business.
The core components of SASE are the four elements that make up the service delivery model, namely, network security functions, cloud security services, networking, and the cloud. The network security functions include technologies like secure web gateways, SSL inspection, intrusion prevention systems, and firewalls. Cloud security services include software as a service (SaaS) security, cloud access security brokers (CASB), and data loss prevention solutions. Networking includes software-defined networking (SDN), WAN optimization, and mesh networks that enable businesses to deliver network services at scale. The cloud is the last element and provides the platform on which SASE is built.
The SASE model provides a framework for delivering integrated and comprehensive security services that can be deployed across multiple clouds and networks. It is designed to simplify and streamline network security processes, providing a unified and efficient network security architecture. By using SASE, businesses can consolidate their network security services and reduce the complexity of managing multiple solutions. SASE enables businesses to unify disparate security systems and deliver security services at scale, all while minimizing the cost and complexity of managing security.
One of the significant advantages of SASE is that it provides a zero-trust network access strategy. Zero-trust network access means that access to resources is granted only after the user is authorized, authenticated, and vetted. This means that even if an attacker gains access to the network, they will not be able to access critical corporate resources. Zero-trust network access is essential for businesses that need to secure their network infrastructure and intellectual property from a wide range of threats.
Furthermore, SASE’s cloud-based architecture enables businesses to scale their security services quickly and cost-effectively. SASE’s cloud-native design means that updates and improvements to security services can be deployed to all users and devices globally, ensuring that the latest security threats are addressed as soon as possible.
SASE also makes it easier for businesses to manage network security policy across different environments, including the cloud, on-premise, or hybrid cloud environments. The centralized policy management and enforcement help businesses to reduce the time and effort required to manage security policies, ensuring that they are uniformly applied across all locations.
Secure Access Service Edge (SASE) is a comprehensive and integrated security services delivery model that is designed to provide businesses with a simplified, efficient, and secure network security architecture. SASE consolidates various security solutions and provides a unified security model that offers businesses and users secure access to resources from any location. SASE’s cloud-native architecture enables businesses to scale their security services flexibly, while zero-trust network access offers a robust and effective security strategy. With its many advantages and benefits, SASE is fast becoming the go-to network security framework for businesses that want to secure their network infrastructure in a distributed and cost-effective fashion.
