What is SASE Security?
SASE (Secure Access Service Edge) is a security framework introduced by Gartner in 2019. It combines wide-area networking (WAN) capabilities with comprehensive security services like:
- Secure Web Gateway (SWG)
- Cloud Access Security Broker (CASB)
- Firewall as a Service (FWaaS)
- Zero Trust Network Access (ZTNA)
- Software-Defined WAN (SD-WAN)
All delivered through a unified, cloud native architecture.
Unlike traditional security models that rely heavily on centralized data centers, SASE enables secure access from anywhere, supporting today’s hybrid workforce.
Core Components of SASE
| Component | Description |
| SD-WAN | Optimizes network performance and routes traffic efficiently |
| ZTNA | Enforces identity-based access with the principle of least privilege |
| CASB | Monitors and controls cloud app usage |
| SWG | Protects users from malicious websites and enforces web usage policies |
| FWaaS | Provides firewall capabilities via the cloud |
These components work in tandem to provide end-to-end visibility and control.
Benefits of SASE for Modern Enterprises
SASE offers several advantages for companies embracing remote work, cloud computing, and BYOD (Bring Your Own Device) policies:
- Simplified Architecture: Combines networking and security into one cloud-based solution.
- Enhanced Performance: Reduces latency through local PoPs (Points of Presence).
- Scalability: Adapts easily to organizational growth.
- Stronger Security Posture: Real-time threat prevention and unified security policies.
- Cost Efficiency: Lowers CAPEX by reducing reliance on physical infrastructure.
How SASE Enhances Network Security
SASE secures traffic regardless of the user’s location, ensuring that:
- All connections are authenticated and encrypted.
- Traffic is inspected and filtered before reaching cloud apps or corporate systems.
- Policies are applied consistently across devices, locations, and users.
