FREMONT, CA: SD-WAN solutions have become too prevalent as organizations demand rapid, scalable, and flexible connectivity between various network environments. The objective of any SD-WAN implementation is to build and maintain a high user experience while reducing the overall Total Ownership Cost (TCO) for connections among remote offices and users and business-critical assets and applications.
As with most technologies, the incorrect SD-WAN solution can severely hinder an organization’s ability to adapt to changing industry needs rather than accelerate them swiftly. And the most prominent challenge is that the wrong SD-WAN solution could pose serious security challenges that could lead the entire system to a screeching halt.
Instant Implementation is the Chief Objective of SD-WAN Self-Healing
The internet is volatile, and network outagesno matter how robust the WAN infrastructure is thought to be—are sometimes inevitable. Inconsistent connectivity is a major challenge, especially for large and distributed businesses across multiple countries and regions that regularly grapple with Internet impairments. But smaller companies can experience the same challenge, particularly if service providers do not adequately manage bandwidth loads during high usage periods.
If the SD-WAN solution has to be modified or intervened manually, every time there is a wider internet connectivity problem, many of the associated benefits of SD-WAN technology become negligible. Similarly, if security needs to be reconfigured every time there is a significant change in connectivity—or even if there is a lag in protection while security is struggling to reconfigure itself—all of the SD-WAN solution advantages are compromised.
Luckily, the best SD-WAN solutions are designed to bridge internet reliability gaps to achieve maximum application performance. How? Quick self-healing when interruption or interruption affects connectivity by switching to an alternative transport model. And when security and connectivity are fully integrated, as is the case with the Secure SD-WAN solution, security automatically adjusts policies and setups simultaneously as connectivity changes, even when swapping to another transport model.
