What is SASE?
SASE (Secure Access Service Edge) represents a convergence of networking and security services into a unified, cloud-delivered architecture. It combines SD-WAN capabilities with security functions to support the dynamic, secure access needs of modern organizations.
Core Components
SD-WAN
Software-defined wide area networking that provides intelligent routing and network optimization:
- Dynamic path selection
- Application-aware routing
- QoS management
- WAN optimization
CASB
Cloud Access Security Broker providing visibility and control over cloud services:
- Cloud application discovery
- Data security
- Threat protection
- Compliance monitoring
ZTNA
Zero Trust Network Access implementing identity-based security:
- Identity verification
- Least privilege access
- Continuous monitoring
- Microsegmentation
SWG
Secure Web Gateway protecting users and devices:
- URL filtering
- Malware protection
- SSL/TLS inspection
- Data loss prevention
Key Benefits
Simplified Architecture
