SD-WAN solutions have become increasingly popular as organizations request fast, scalable and flexible connectivity between different network environments and seek to reduce the total cost of ownership (TCO) while preserving the user experience.
A wrong SD-WAN solution can significantly inhibit an organization's ability to adapt quickly to changing business demands, primarily because it creates new security headaches.
Here I’ll share five requirements for a solution SD-WAN secure that is flexible, scalable and tailored to the needs of today's distributed companies.
Goes beyond the Branch
SD-WAN it may be better understood to support complex branch deployments and help organizations reduce their reliance on branch routers and other legacy technologies.
Effective solutions for SD-WAN go far beyond the needs of affiliates, however. Its functionality can be extended for use in home office and teleworker - especially devices with LTE integrated for consistent connectivity - and across distributed clouds.
The solutions SD-WAN they also need to come in virtual versions that are available in multi-cloud environments and have deeper integration to allow the cloud to rise, enabling the adoption of efficient SaaS.
Offers intuitive orchestration and touch-free deployments
Both features enable faster scale-out configuration deployments, often in minutes, to allow for the best possible performance of collaborative applications such as VoIP, video conferencing and various SaaS applications, even for remote users based away from the corporate data center.
Orchestration allows for overlapping automation (VPN) for the most complex network with intuitive workflows.
Prioritizes critical applications and allows for self-healing WAN
Connectivity alone is not enough, especially in a remote, heavy-duty environment. A solution needs to identify a broad set of applications to meet all use cases, while advanced self-healing WAN automation will provide a consistent user experience on any transport for any user.
Many solutions SD-WAN only support limited use cases, limited number of users and / or specific environments.
Includes integrated security
The difference between SD-WAN and Secure SD-WAN is that the latter is a solution, while the former is a connectivity offering that provides another channel for the bad guys to attack your network.
An overlay security solution cannot adapt to dynamic connectivity environments; security needs to be built into every SD-WAN device, allowing home users, branch office users and the data center to use a common set of security policies and application criteria.
In true secure SD-WAN, network, connectivity and security functions are so integrated that they are the only solution that meets three needs, instead of three different solutions.
Offers comprehensive analysis and reporting
A secure SD-WAN solution needs to help organizations gain visibility into network and application performance (real-time and historical statistics). This includes improved analysis, as well as improved compliance.
A single console and rich SD-WAN analysis can help you adjust your business and security policies to improve the quality of the experience for all your users.
