Secure Access Service Edge (SASE) is a new concept that promotes better and more secure enterprise networking by deliberately integrating enterprise networking with enterprise security. This concept covers the underlying network infrastructure and the application of network security as a layer across this infrastructure. 

SASE comprises five fundamental network and security technologies: 

• Software-defined wide area network (SD-WAN), 
• Secure web gateway (SWG), 
• Cloud access security broker (CASB), 
• Firewall as a service (FWaaS), and Zero Trust Network Access (ZTNA). 

SASE administrators apply these technologies through a centralized and unified management structure. 

SASE delivers three primary functions: Network Traffic Optimization, Secure Access Control, and Cyber Threat Prevention. SASE platforms also provide advanced security features like Security agent on devices, Browser isolation technology, and Continuous adaptive risk and trust assessment (CARTA) strategy. The Secure Access Service Edge market is expected to triple by 2026, exceeding $13 billion.

SASE is gaining momentum as a new approach to cybersecurity. It addresses the challenges that traditional security models face due to the shift of the workforce to remote work environments. Employees are accessing sensitive data from different locations and devices, creating the need for better visibility and control to protect digital assets. SASE enables organizations to provide secure access to applications, data, and systems for their remote workforce.

One of the primary benefits of SASE is its ability to deliver network security from the cloud. This means that security services are available to remote users no matter where they are or what device they are using. SASE provides better protection than traditional VPN solutions because it includes advanced security features like browser isolation and continuous adaptive risk and trust assessment (CARTA) strategy.

Another benefit of SASE is that it delivers comprehensive security services that combine multiple network and security technologies. This approach provides better security because it combines multiple security layers that work together to protect digital assets. SASE solutions also provide better visibility and control over network traffic, which is essential for identifying and mitigating potential security threats.

The SASE market is expected to grow rapidly due to the increasing demand for cloud-based security solutions. The market includes both established and new players, including network security vendors, cloud service providers, and SD-WAN vendors. Organizations are adopting SASE solutions to provide secure access to remote employees and protect digital assets from potential cyber threats.
