Cisco has released an updated version of its SD-WAN software, now at version 26.1.1, which strengthens security and integrates enhanced AI features. These updates allow enterprise customers to define security policies in a uniform manner across their entire network, providing end-to-end visibility and facilitating a transition from traditional WAN setups to a more AI-optimized infrastructure without needing a significant architecture overhaul.
The new security features are part of Cisco’s broader "Resilient Infrastructure" initiative, focused on bolstering network security through enhanced default protections, removal of outdated features, and the addition of new capabilities that reduce potential vulnerabilities. Specifically, the SD-WAN software addresses weaknesses in command line interface (CLI) and user interface (UI) configurations to safeguard against unauthorized access and privilege escalation.
Cisco’s enhanced tools include a centralized dashboard for identifying insecure or outdated configurations across the SD-WAN fabric, allowing real-time assessment of device trustworthiness and providing guided actions for vulnerability remediation. Insecure configurations are categorized into several areas, leading to specific recommendations aimed at enhancing overall security.
Additionally, the software allows for simplified firewall management by enabling policies to be defined at an organizational level, streamlining enforcement of consistent policies across multiple sites. This is particularly important for distributed organizations where operational efficiency is crucial. The improvements in Transpor Layer Security decryption capabilities support the increasing volume of encrypted internet traffic, aiding in effective threat detection without compromising performance.
Recognizing the growing application of AI, Cisco’s SD-WAN is now better equipped to identify and categorize AI-based application traffic across various environments. This enhancement allows organizations to implement performance optimization and governance policies specific to business-critical AI workloads, ensuring that security measures are also applied consistently.
Moreover, the updated software features an advanced AI Assistant designed to assist users with troubleshooting, network performance monitoring, and managing support cases. This integration aims to enhance operational efficiency and streamline support processes.
