Challenges for enterprises with SD-WAN deployment

With the ever-growing popularity and deployment of the network services in enterprises, the technology is rapidly innovating. One such technological innovation of the current times is the modern Software-Defined Networking. The SD-WAN technology is a rich feature that consolidates networking with secure reporting and management to a managed WAN platform

The SD-WAN solution tends to delegate the responsibility of managing the network to the end customer. With SD-WAN, the customers typically monitor, distribute, and modify the SD-WAN solutions while fully managed SD-WANs involve the outsourcing of the deployment, monitoring, and management of the SD-WAN solution. This is usually done through a cloud-based management portal.

Like any other new or developing technology, SD-WAN has its challenges. While marketing from most vendors presents it as a do-it-yourself self-managed technology, the users must be aware of the potential risks, challenges, and deployment risk factors. There are several factors to consider when organizations decide to select, deploy, and configure the best SD-WAN solutions for their business.


Managed WANs utilizes the bandwidth of comparatively insecure internet connections. Which potentially exposes enterprise devices to security attacks and data breaches. Therefore, SD-WAN solutions and deployments require additional security to ensure that data is protected and the corporate policy is enforced at distributed locations. Essential security features include policy control, traffic visibility, and protection against direct threats and attacks.

SD-WAN security

Most network providers have added a level of built-in security to their platforms, including encryption and firewalls. Managed WAN platforms integrated with automated policies allow users the ability to whitelist and blacklist traffic from specific locations.

Vendor Viability

The SD-WAN market is dynamic, robust, and riddled with suppliers. The number of Managed WAN network providers and active suppliers is many.

As more and more businesses adopt, SD-WAN differentiating among various features & WAN services become more complicated. This compels enterprises to take a standard Managed Software Defined Network that will not require additional IT expertise to modify, unless some specific set of features are needed.

Industry experts expect that several minor SD-WAN suppliers will either exit the market or face acquisition near the future. It is recommended that IT executives should evaluate the mid-term viability of their SD-WAN solutions with care and foresight.

Improved SaaS Support

Enterprises depend on SaaS suppliers to supply them with the best applications for unified communications, CRM, office suites, accounting, and more. For a network providing support to these applications is challenging because each SaaS provider has its own unique set of services and tools.

SD-WAN platform offers improved SaaS support.  Enterprises can set specific policies, compliance, and security criteria within the management portal for each service. Having

more and more SD-WAN suppliers are now innovating and are designed to deliver appropriate Quality of Service (QoS) to critical SaaS applications without IT intervention.

Network connectivity selection:

Global enterprises are seen to face other networking challenges which often local enterprises don’t. Having connectivity from an international Internet Service Provider (ISP) with a single backbone is not always possible. Traffic delays due to movement from ISP to ISP and troubleshooting delays between service providers are some of the potential issues facing global business networks. In this case, it is essential that IT teams do investigate and consider potential advantages and disadvantages while selecting their SD-WAN supplier.
