2. What is Aryaka's SD WAN solution?

Aryaka LogoAryaka is an interesting proposition as their WAN infrastructure is based on an MPLS (multiprotocol label switching) PoP deployment. In a sense, the solution is a software WAN evolution of the MPLS VPN. As a Challenger on the Gartner magic quadrant, they offer 25+ Global POPs, physical hardware and Cloud-based SD WAN controller support. WAN optimisation is built in to the Aryaka solution.   Leading brands are using Aryaka such as Skullcandy, Air China and other notable partners including Microsoft Azure & AWS Cloud. The Aryaka capability is made up of Smart Connect (WAN optimisation), SmartCDN (IP and Web app acceleration) and Cloud VPN.   If your business is reluctant to move away from private based, QoS (Quality of Service) enabled MPLS circuits, Aryaka is worth considering as a good half way networking and security capability.

3. What is CATO's SD WAN solution?

CATO LogoCATO is listed as a Gartner Visionary, formed in 2019. In a similar fashion to Aryaka, CATO offers 40+ Global PoP locations. Physical, virtualised and Cloud via AWS. CATO is viewed as a great solution for the SME or large Enterprise with a large number of remote users. With next-generation Firewall security included within the solution capability.   Interesting fact, CATO is led by Shlomo Kramer , co-founder of the security giant Check Point Software.

5. What is Oracle's (Talari) SD WAN solution?

Oracle logoAs a well-known brand, Oracle (Talari) has been around for some time now. Viewed as a niche provider by Gartner, their solution is edge-based with physical, virtual (VMWare, Hyper-V, KVM), Cloud via AWS and Azure) with either on premises controller technology.

 is offering WAN optimisation at no additional cost and granular network performance measurements taken with every single packet. The security offered is basic with advanced offered by partners.   As of writing this article, Talari is on their 7th generation SD WAN platform with 500+ customers and 9000 site deployments worldwide. The pitch suggests their capability meets the demands for physical, virtual or cloud nodes. Alongside Talari Sofware-Defined WAN, their bandwidth liquidity capability offers an orchestrated solution that consolidates legacy equipment. A key takeaway is their ability to enable sub-second response when detecting network issues and intelligent link aggregation which will use all bandwidth across disparate links even for a single TCP application flow.

6. What is Cisco Meraki's SD WAN solution?

Cisco Meraki LogoThe Cisco Meraki platform offers significant benefits including CCTV, an edge-based Gartner leader with physical and Cloud via AWS or Azure. The inbuilt next-generation Firewall licence, single pane of glass management and WiFI switching mean Meraki is a great solution for a business requiring monitoring.

Meraki is best suited to Internet-only rather than supporting private technologies such as MPLS. While MPLS lines can be supported, deployment does require expertise.  Meraki is also known as a DIY technology vs some solutions which are part or fully managed. We've recently worked on a large 300 site deployment using Cisco Meraki into MPLS primary with failover to Broadband/4G. The complexity of delivering the solution surrounds working with MPLS routing rather than using the public Internet. With this said, the capability works well and is fit for purpose.

7. What is Citrix's SD WAN solution?

Citrix Logo-1A 2013 SD WAN offering, Citrix are a challenger within the Gartner magic quadrant and no stranger to cloud-based apps. As with most provider and vendors, Cirtix are offering edge-based connectivity with physical, Citrix HyperV, KVM, VMWare and Zen with Cloud-based using Alibaba, AWS, Azure, Google and Oracle. Citrix SD WAN is viewed by the market as a single WAN optimisation device with good network visibility.   Citrix produce an SD WAN buyers checklist but this really revolves on an overview of their strengths which typically drives you down a path of selecting their services. With this said, the Citrix capability does compare well overall with every provider & vendor.

Conclusion

We recognise that one of the major challenges for any IT team considering SD WAN services is to force transparency across the massive amount of hype and marketing currently generated by service providers and vendors.

Compounding the issue is the need to also identify niche and specialised software-defined WAN players you may not have considered at the same time as ensuring security and access is considered across users and their cloud-based applications. If you are conducting research you'll find the 'lesser-known' solutions are essentially hidden behind the content-generating power of larger SD WAN companies.

And even with the base level of data-points, every Enterprise brings their own specific requirements across branch offices & HQ cloud-based, delay sensitive voice/video and mission-critical SaaS applications and their access, security policies, data centre, migration, budget, support, WAN optimisation, uptime and, well, you probably get the idea. It's kind of time-consuming and confusing.

With digital transformation at the top of the IT Manager or CTO's agenda, which SD WAN features should you deploy and which solution should you choose to ensure reliability, support for users and their apps?
