SD WAN Managed Services

Who are the best Managed SD WAN Providers (MSP's)?

The best Managed SD WAN providers are Aryaka, BT Business, Cato Networks, Colt, GTT, Lumen, Masergy, Open Systems, Versa and VeloCloud. Managed service comparison requires evaluation across SLA, Change requests, Underlay and overlay support, Co-managed and additional services such as SASE Security, LAN and Wifi.

In this article, I'll be discussing 10 SD WAN vendors and service providers which fit the needs of most mid-market and Enterprise businesses. While SD WAN is known for ease of use, expertise and resource is still required depending on the complexity of your needs. SD WAN typically encompasses:

  • Path optimisation
  • Support for bonded bandwidth across Ethernet, Broadband and Cellular
  • SASE security
  • AI and cloud vendor support for AWS, Azure and Google cloud
  • Out of the box application recognition for SaaS (Software as-a-service)
  • Zero touch provisioning for efficient solution orchestration
  • Self-managed (DIY)
  • Co-managed
  • Fully managed
List of the top 10 Managed SD WAN service providers (MSP's):
  1. Aryaka
  2. BT Business
  3. Cato Networks
  4. Colt
  5. GTT
  6. Lumen
  7. Masergy
  8. Open Systems
  9. Versa
  10. VeloCloud

A benefit of a managed SD WAN is having a central and clear system which unifies communication between your IT team and the provider. This leads to simplified configuration, deployment, change request and maintenance. There are benefits for a DIY system such as reduced time to complete a process change, as you don’t have to go through the provider first. Some vendors offer fully managed services but others require the customer to engage with their partner network.

By 2025, as a result of digital business projects, 75% of enterprise-generated data will be created and processed outside the traditional, centralised data centre or cloud.

VeloCloud by VMware

VeloCloud only offers fully managed solutions, but with a slight twist compared to other providers. They allow for their partners such as GTT, BT and Lumen to offer managed SD-WAN services based on the VMware SD-WAN.

SASE can be implemented via the VMware SASE Platform™ which allows for secure and reliable access to applications and sites. Services include; SD-WAN gateways, Zero Trust Network Access (ZTNA) and firewall capabilities. Centralised management, advanced analytics and network-wide business-based policies are available via the VMware SD-WAN Orchestrator.
