SD-WAN and SASE: a modern alternative to MPLS
Networking · 1 min
Articles by Ricardo Vaz
SD-WAN and SASE are transforming enterprise networks, combining intelligent connectivity, secure access, and improved integration with cloud applications.
TL;DR
- MPLS was designed for datacenter-centric architectures
- SD-WAN optimizes traffic routing based on the needs of each application
- SASE integrates security capabilities and secure access into a single architecture
- Network modernization can increase operational flexibility and simplify management
Why many organizations are rethinking MPLS
MPLS networks were designed at a time when most applications resided in corporate datacenters. Today, a growing portion of enterprise traffic is directed towards SaaS applications and cloud services, creating new requirements for performance, flexibility, and security. In this context, many organizations are evaluating architectures more suited to modern work models.
What SD-WAN and SASE offer
SD-WAN allows for the use of multiple network connections, dynamically selecting the best path for each application or service. Complementarily, SASE combines functionalities such as Secure Web Gateway (SWG), Cloud Access Security Broker (CASB), [Zero Trust Network Access](/en/solutions/zero-trust-ztna) (ZTNA), and Firewall as a Service (FWaaS), integrating connectivity and security into a unified approach.
A phased migration
The adoption of these architectures can be done gradually, initially coexisting with existing infrastructures. This approach helps reduce operational risks and adapt the network to the organization's needs without significant service disruptions.
