Day 2 | SD-WAN (Software-Defined Wide Area Network) 🔗 Day 2 of 6 - SD-WAN SD-WAN = Software-Defined Wide Area Network. It's the foundation of SASE, making networking flexible and intelligent. Traditionally, companies used expensive MPLS lines to connect offices. Today, SD-WAN lets you use multiple internet links (broadband, 4G/5G, fiber) and automatically routes traffic over the best path. Benefits of SD-WAN: ▪Faster & more reliable access to cloud apps. ▪Cost savings (less reliance on MPLS). ▪Centralized visibility and control over the network. 💡 Example: During a Zoom call, if one internet line is slow, SD-WAN automatically reroutes your traffic to a faster connection — without dropping the call. ⚠️ Without SD-WAN: slow SaaS apps, frustrated employees, and rising IT costs. 📌 Tomorrow -> Zero Trust Network Access (ZTNA): the secure replacement for old VPNs. #SASE #SDWAN #HybridSecurity #CloudSecurity #SecurityLearning #KnowledgeSharing
