SD-WAN technology, renowned for its high flexibility, automatic network configuration, and cost-effectiveness, consolidates multiple physical WAN links into a unified logical network, steering the network paradigm from “connectivity-driven” to “service-driven.” Simultaneously, as enterprises pursue efficient networking, the security aspect of global SD-WAN becomes a crucial consideration.

Global SD-WAN employs intelligent networking, a plug-and-play implementation where branch devices come online with zero configuration. For instance, by configuring a box and a data center address, enterprises can push all policy requirements to this box. Beyond simple device validation and authorization, additional device authentication is crucial to ensuring network security. This streamlined process resolves networking challenges for chain enterprises, significantly reducing networking costs.

Moreover, the security of global SD-WAN manifests in the following key features:

Encryption Algorithm Safeguards:

All data transmitted through global SD-WAN tunnels undergoes AES/3DES encryption with 128-168-bit encryption. This effectively prevents eavesdropping and tampering of data, ensuring secure transmissions.

Strict Key Authentication:

Global SD-WAN systems implement rigorous key authentication, permitting access only to users who possess the correct key, thus preventing unauthorized intrusion. Keys are centrally managed by the company’s network administrator and can be changed at any time, enhancing system security.

iNAS Digital Certificate Technology:

Supporting the PKI authentication system, iNAS binds the hardware information of global SD-WAN users’ computers, such as hard drive, CPU, and network card. Access is granted only when the username, key, and user digital certificate comprehensively pass authentication. Even if usernames and passwords are compromised, the integrity of the global SD-WAN network remains intact.

Intranet Management Functionality:

Robust intranet management features ensure that branch offices, upon connecting to the central LAN after international SD-WAN implementation, can only access resources allocated by central administrators. Different branch offices can have distinct access permissions, preventing malicious attacks through the intranet and effectively safeguarding the network.

In summary, international SD-WAN technology not only delivers efficient network operations for enterprises but also provides a reliable safeguard for their network architecture through its outstanding security features. Choosing international SD-WAN allows enterprises to enjoy flexibility and cost-effectiveness while ensuring the security of their networks, facilitating the smooth development of business operations.
