Smart Access Gateway (SAG) is an intelligent, secure, and reliable service that facilitates gateway management in the console.
Intelligence
SAG supports automatic configurations and zero touch provisioning (ZTP), and automatically adapts to network topology changes.
Reliability
SAG connects to nearby access points in a metropolitan area network. On-premises networks can be connected to Alibaba Cloud through primary and secondary connections/devices.
Device-based HA
SAG devices support the active-standby mode. If the active device fails, network connections are switched to the standby device.
Link-based HA
Each SAG device provides two encrypted links to implement automatic optimal link selection and real-time link failover if errors occur.
Security
SAG supports hybrid clouds and encrypted private connections. Internet data transmission is encrypted.
Data encryption
You can use the IKE and IPsec protocols to encrypt data transmission.
Anti-replay
SAG authenticates data sources to prevent replay attacks.
Web tamper proofing
SAG provides multiple methods to authenticate data.
Centralized management
The SAG console allows you to perform management operations centrally.
