When adopting SD WAN services, an important consideration should be the type of provider selected to deliver the solution. In this article, we shall discuss the types of SD WAN providers, what approach to SD WAN implementation they are suitable for, examples of each and how a particular provider may align with your business requirements.

What are the different types of SD WAN provider?

As a general rule of thumb, SD WAN vendors offer managed and “Do-It-Yourself” (DIY) services across a range of their proprietary products. However, this depends entirely on the vendor; some provide complete end-to-end managed services of their solution, and some offer it as an optional extra. Others do not provide services directly and instead rely on partners and distributors to facilitate this. An SD WAN vendor is suitable for businesses with underlay networks and IT teams. A vendor is ideal for those that require network management in-house to meet compliance requirements, such as in the Financial or Legal services industries.

Service Providers are usually larger network providers that can offer connectivity in the form of an underlay network. Service Providers generally offer SD WAN from multiple vendors and can often provide an additional portfolio of services, such as Security or Professional Services. A Service Provider can assist in almost every aspect of a network’s deployment, bundling services tailored to meet a business’s individual needs.

An MSP tends to service a specific customer need. An MSP specialises in niche requirements and, to do so, often focuses on a few select vendor solutions. Potential clients should note now that MSPs are only suitable for customers whose needs fit or match an MSPs offering, not the other way around. The MEF has criticised the lack of standardisation for managed services. However, this is a fallacy, as every business, its requirements, and its goals will always be unique. In this way, since there is no standard business to model managed services on, an MSP will be well-suited to some customers and not fit at all for others since they tend to specialise in particular customer requirements.

SD WAN Vendors

Cisco Logo

Cisco provides two approaches, Cisco Viptela and Cisco Meraki offerings. The two solutions cover the majority of the market. The Cisco Meraki solution offers a simplified, easy-to-manage approach to SD WAN, ideal for small to medium-sized businesses with limited IT resources. On the other hand, Cisco Viptela, the traditional Cisco solution aimed at large, multinational organisations, is a higher-cost, more advanced, and feature-rich SD WAN solution. The complexity of the solution requires sufficiently skilled IT staff, and smaller firms may find the solution challenging to manage. Cisco products are only offered through Cisco-certified partners or distributors and do not offer any managed service. However, both solutions benefit from native integration with Cisco’s broad portfolio of products and services. See more  for Cisco Viptela here. See more  for Cisco Meraki here.

The BT Group is the largest broadband, fixed line and mobile service provider in the United Kingdom. BT can design, build and deliver IT solutions leveraging decades of experience and expertise, with operations in approximately 180 countries. The BT Global Services Division offers SD WAN through partnerships with VMware, Cisco (Meraki & Viptela), and Prisma from Palo Alto Networks. BT offer flexibility with solutions customised to meet the requirements of the customer. BT can provide networking, security, digital workplace and customer contact services with customers receiving ongoing assistance from BT support services. BT’s services are available in most countries. However, the providers’ network and coverage are robust in the UK and Europe, making it a suitable choice for businesses with most of their locations in this area. BT’s offering is split between small-medium companies and global enterprises to distinguish services and improve customer support. However, as a large telco, they may not be as agile in adopting new technologies across the entire business as some smaller competitors. See more here.

Verizon MPLS Logo

Similarly to BT, Verizon is a prominent American telecommunications provider that offers directly managed SD WAN and SASE security. Verizon has over 30 years of experience managing networks and operates in 150 countries with a team of 300 experts to support customer needs. Like BT, the company’s focus and strengths are primarily within its domestic market. To this end, Verizon is a good option for businesses with most branches in North America. This recommendation applies to any size North American company; however, caution here as, unlike BT, there is currently no distinction between services for Small to Medium Enterprises (SMEs) and large global enterprises. The lack of a difference between services may negatively impact customer service regarding the speed of support and communication with the customer. See more here.
