Secure Access Service Edge (SASE) is an orchestration of networking technology, security solutions, and strategies into a cloud-oriented platform that securely connects users with the tools and resources needed to complete work.

SD-WAN
A software-defined wide-area-network, or SD-WAN, is networking technology that centralizes the operations of remote working sites and cloud-based services. This technology is an essential pillar in SASE architecture because SASE combines the networking capabilities of SD-WAN services, cloud-based security solutions, and zero-trust strategies.
By utilizing Cisco’s SD-WAN technology, businesses have access to flexible networking infrastructure, integrated security, mutlicloud capabilities, and insightful analytics that all make SASE possible.
CLOUD SECURITY COMPONENTS
SASE architecture requires security components that automatically mitigate risk factors and assist in authenticating user access to cloud-based data and applications. For example, next-generation firewalls prevent threats from accessing a network and remediate threats in real time. DNS layer security solutions verify connections made between internet resources and users on the network, which prevents malicious websites from ever establishing a connection with trusted sources.
SASE security components are customizable solutions that businesses implement based on their IT environment and security standards. A few of the other security solutions that are used in SASE architecture include:
- Cloud Access Security Broker (CASB)
- Data Loss Prevention (DLP)
- Remote Browser Isolation (RBI)
- Threat intelligence
- Virtual Private Network (VPN)
ZERO-TRUST SECURITY
Zero-trust is an approach to cybersecurity that requires users to continuously authenticate their access to the network, applications, and sensitive data, no matter who they are or where they connect from. By treating every endpoint and connection as a potential threat vector, zero-trust security keeps a business’ network secure as users work from different devices and travel. When combined with the networking and security services needed for SASE, zero-trust allows businesses to protect their data while deploying cutting-edge technology needed in the modern work force.
