SASE (Secure Access Service Edge-”sassy”)
SASE (Secure Access Service Edge): SASE is a cloud-delivered network security model that Gartner introduced in 2019 to address modern enterprise security challenges. It converges networking (SD-WAN) and security functions (like firewalls, zero trust, and web gateways) into a single, cloud-native service. SASE eliminates the traditional perimeter-based security approach by making security follow users and data, rather than locations. The model authenticates based on identity, real-time context, and security policies, not network boundaries. This architecture enables secure access for any user, on any device, from any location to any resource.
Components
SASE combines networking elements (SD-WAN, WAN optimization, bandwidth aggregation) with security services (CASB, Zero Trust, Cloud SWG, FWaaS) in an integrated cloud platform. The network side ensures optimal connectivity and performance across global locations and cloud services. The security side delivers comprehensive protection including data security, threat prevention, and access control. Key components work together seamlessly through a single management interface, eliminating the complexity of multiple point solutions.

Implementation Approach
Organizations should start with an assessment of current network and security capabilities, identifying gaps against SASE requirements. Begin with the most critical use cases - typically securing remote workers and cloud access - while developing a phased migration plan. Select a provider with proven SASE capabilities and global points of presence to ensure performance. Consider starting with security components (SSE) before full SASE if needed. Maintain clear success metrics focused on risk reduction, cost savings, and user experience.
Business Benefits
SASE delivers immediate cost reduction by eliminating multiple security products and simplifying operations through a single cloud service. It enables business agility by securing work-from-anywhere and rapid adoption of cloud services without compromising security. Risk is reduced through consistent security policy enforcement across all users, locations and resources. User productivity improves through better application performance and simplified access. The model scales automatically with business needs while reducing capital expenses through the cloud consumption model.
Market Leaders
Palo Alto Networks (Prisma SASE) leads through its comprehensive security capabilities and unified platform combining Prisma Access and Prisma SD-WAN. Cisco (Cisco Plus Secure Connect Now) leverages its networking dominance and security portfolio including Umbrella, AnyConnect, and Meraki. Zscaler (Zscaler Zero Trust Exchange) is recognized for its cloud-native architecture and extensive global points of presence. VMware (VMware SASE) offers strong integration of VeloCloud SD-WAN with comprehensive security services. Fortinet (Fortinet SASE) stands out for its FortiGate-based converged networking and security approach with strong price-performance value.
Significant Challengers
Versa Networks excels in offering highly integrated SASE capabilities through its single-pass architecture and unified console. Cato Networks pioneered cloud-native SASE with its private global backbone and converged security stack. Check Point (CloudGuard SASE) brings its strong security heritage to SASE with comprehensive threat prevention. Microsoft (Microsoft 365 Security) leverages its cloud dominance and identity expertise for SASE delivery. Netskope offers particularly strong data and cloud security capabilities within its SASE framework.
Emerging Providers
Perimeter 81 focuses on simplified SASE deployment for mid-market organizations. Aryaka combines its global private network with security services for enhanced performance. Forcepoint SASE emphasizes data security and user behavior analytics. Akamai (Enterprise Application Access) leverages its CDN for edge security services. Open Systems provides managed SASE services with strong European presence.
Some Evaluation Criteria
Organizations should evaluate vendors based on global coverage, integration level between networking and security, cloud-native architecture, and operational simplicity. Performance and user experience across diverse locations and applications are critical factors. Security capabilities should align with zero trust principles and support broad threat protection. Total cost of ownership including operational impact should be carefully assessed. Vendor financial stability and roadmap alignment are essential for long-term success.
