Implementing a Cisco SD-WAN architecture offers several advantages, particularly in terms of security and application-aware networking.
* Security Integration: Cisco SD-WAN integrates both embedded and cloud security features, enhancing endpoint protection. This integration allows for a more robust security posture that can adapt to the evolving threat landscape. The architecture transforms Cisco routers into advanced security devices with an enterprise firewall, intrusion prevention system (IPS), URL filtering, and continuous DNS monitoring, ensuring end-to-end protection.
* Application-Aware Policies: Cisco SD-WAN enables the configuration of application-aware policies that are enforced in real-time. This capability ensures that critical applications receive the necessary bandwidth and performance, even in complex network environments. It allows for intelligent path selection based on the application's needs, improving overall application performance and user experience.
