Migrate from DIY SD-WAN To a SASE Experience

In 2021, Gartner reported 45% SD-WAN adoption by enterprises, expected to rise to 70% by 2026, driven by the desire to improve edge network connectivity, user and app experiences, operational efficiency, and cost savings.

EMA’s April 2023 research shows 66% of enterprises prefer managed SD-WAN services due to challenges in maintaining skilled in-house staff, keeping up with technology, and negotiating with vendors. IDC echoes these reasons.

Forbes highlights that DIY SD-WAN adopters face more challenges in transitioning to SASE. Additionally, 40% of managed SD-WAN service users prefer it for its better integration with services like SASE security.

Self-Managed SD-WAN Challenges​

Reactive Operations Lacking 24x7 Support​

Most of your scarce IT resources are used to manage the network, application and security infrastructure – usually in firefighting mode and not 24x7 – and there is little time for strategic projects.​

Missing End-To-End Quality Assurance​

None of the existing SD-WAN or SASE technologies can provide end-to-end SLAs which would guarantee high app performance and hence, good user experience. Particularly for users at remote or difficult locations like China.

Scattered Security Increasing Risk

If SD-WAN and security technologies are operated separately, there is usually a challenge to manage the scattered point solutions effectively due to missing know-how and skills and because it is time consuming and error-prone.​
