Secure SD-WAN deservingly remains one of the more in-focus technologies when it comes to an increasingly digitized world, dynamic businesses, their ever-evolving requirements, resulting disruptions, and digital transformation goals.

The sustained and growing interest in a software-defined approach for managing the WAN seems justifiable.

• SD-WAN brings speedier deployment, fewer complexities, and agility.
• Better network-application performance and cloud usage.
• Robust network security.
• Substantial cost savings and double-digit ROIs within months.

Fast, flexible, and scalable connectivity between network environments – that’s what makes SD-WAN the preferred choice for numerous enterprises across industries. However, can connectivity be the only factor to consider?

Common Challenges?

• Proper functioning of business-critical applications, especially for organizations that have scaled out SSL/IPSec VPN connections between the core network and their remote workers.
• Managing connections between environments to prioritize vital local networks and cloud apps.

Isn’t the SD-WAN designed precisely for looking after these concerns? Yes, the Appropriate or the Right One Is! 

Inadequacies of a Less-than-Appropriate SD-WAN

• Designed for particular environments and restricted number of users.
• Supports limited use cases.
• Inhibits the adaptability to changing business demands.
• Creates new security issues.
• An overlay security solution is unable to adapt to dynamic connectivity environments, specifically those spanning multiple environments.

The Solution?

A Correctly-Deployed More Relevant Secure SD-WAN, the Indispensable Enterprise Technology, not Confined to the Branch

• Capable of high flexibility and rapidly scaling from home users/branch offices to high-performance data centers or distributed cloud environments.
• Ensuring business continuity for extended and continuously expanding remote workforce while accommodating measured infrastructure resources and limited technical staff.
• Centralized management and zero-touch deployments lead to quicker within-minutes configuration rollouts at scale.
• Enabling optimum performance of video/audio conferencing, SaaS, and other collaboration applications even for remote users or large groups.
• Supporting data-center-to-cloud, campus-to-cloud, and work-from-home use cases.
• Connecting clouds for best-achievable user experiences.
• Protecting key applications and assets.
• An SD-WAN device with a full stack of embedded security.
• Assisting branch offices, data centers, and home users with common security policies.
• Providing reliable protection across the complete distributed environment.
• Available in a variety of form factors and virtual versions for addressing large data centers, branch offices, small home offices, remote sites’ needs, and cloud deployments.

Possible SD-WAN Use Cases

• Home Offices:
• On-demand remote access.
• Dynamically scalable performance, irrespective of the local network availability.
• Consistent connectivity and carrying out business-critical activities through SD-WAN desktop appliance with built-in LTE.  
• Branch:
• Advanced routing and cloud on-ramp for supporting intricate branch deployments.
• Reducing dependence on point products ill-equipped for managing traffic congestion across public networks.
• Integrated security for protecting direct connections to cloud and internet applications/services.
• Data Center:
• Traditional SD-WAN for accessing pivotal data center applications/resources.
• A high-performance solution for steady and secure connectivity in environments with data centers sharing information with the cloud or applications/workflows spanning different data centers.
• Distributed Cloud:
• Interconnecting cloud environments, translating into enhanced user experiences.
• Combining an IPSec VPN with native application steering and fully-programmable APIs.
• Building efficient cloud integration frameworks for allowing quick access to critical applications/resources. 

Sufficient attention must be diverted to SD-WAN’s more influential roles within your enterprise.

It can play a decisive part in quick-secure new networking environments’ rollouts and connecting users/resources to data or applications. Single remote workers, branch offices, high-performance data centers, and distributed cloud environments can be securely connected to the distributed network, shortening deployment times.

Simultaneously, as deployments spread, we cannot downplay the necessity of advanced management-orchestration tools and an integrated SD-WAN orchestrator for improving performance and scalability.
