Why SD-WAN is the future of Site Connectivity<\/h3>\n\n\n\n
Point-to-point networks, Internet VPN, MPLS: there have always been new trends in the field of corporate networks in the past. SD-WAN networks<\/a>, on the other hand, are a real evolution in the field of Site Connectivity. With its innovations, SD-WAN technology is now adapting better and better to the requirements of companies. Examples include security, the availability of applications and the diversity of end devices.<\/p>\n\n\n\n
1st advantage: The independence of the underlay network<\/h3>\n\n\n\n
As with Internet VPN, SD-WAN is a private network within which data is exchanged via encrypted “tunnels”. Regardless of whether it is a dedicated Internet line, MPLS line or mobile Internet, as long as there is an IP connection, SD-WAN can use it. An SD-WAN network can therefore be rolled out in the remotest corners of the world without having to invest in expensive infrastructure such as dedicated lines. SD-WAN is based on the existing infrastructure. This means that SD-WAN is cost-efficient and quick to set up.<\/p>\n\n\n\n
2nd advantage: Security through SASE<\/h3>\n\n\n\n
Security through SASE<\/a> means that the user is authenticated at the edge of the network and not in the core. And this authentication is not done for all areas, but on a case-by-case basis, with a list of permissions that determine which applications can be used or seen. SD-WAN can be perfectly combined with a SASE model; this is one of the main differences between SD-WAN and Internet VPNs.<\/p>\n\n\n\n
3rd advantage: A perfect network for the cloud<\/h3>\n\n\n\n
Companies of all sizes are moving inexorably towards the cloud. A user doesn’t care where the SaaS solution is located as long as they can use it. SD-WAN optimizes the data flow. Network traffic is routed in such a way that the most efficient path is always taken.<\/p>\n\n\n\n
4th advantage: SD-WAN creates the same conditions for all users<\/h3>\n\n\n\n
Even before the pandemic, there were employees who worked from home or on the road. The problem was that these early VPNs created a two-tier society within the company. The connection of a traveling sales employee was nowhere near as good as that of his colleague at the company headquarters. With today’s broadband or mobile connections, users outside the office often have access to equivalent bandwidths. This means that an SD-WAN can provide remote or mobile employees with the same resources as everyone else in the organization.<\/p>\n\n\n\n
5th advantage: SD-WANs are flexible and adaptable<\/h3>\n\n\n\n
As SD-WAN is not tied to a fixed infrastructure, it can quickly adapt to new requirements and specifications. For example, company takeovers can be realized quickly. New locations can be easily integrated into the company network with SD-WAN. SD-WAN gives your network the opportunity to grow with your requirements. It can change and develop in line with customer requirements and market conditions, just like your business. The benefits of SD-WAN are too numerous to list. As the above shows, the decision to adopt SD-WAN doesn’t have to be a purely technical one.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Frequently asked questions about the advantages of SD-WAN<\/h3>\n\n\n\n
What is the biggest advantage of SD-WAN over MPLS or classic VPN?<\/strong>
The biggest advantage is independence from the underlay network: SD-WAN uses any available IP connection, whether a dedicated Internet line, an MPLS line or mobile Internet. This lets an SD-WAN network be rolled out cost-effectively and quickly even at remote locations, without investing in expensive dedicated lines. SD-WAN builds on existing infrastructure instead of replacing it, which makes adoption significantly simpler than with classic MPLS.<\/p> <\/div>
How does SD-WAN improve security compared to Internet VPN?<\/strong>
SD-WAN can be perfectly combined with a SASE model. The user is authenticated at the edge of the network rather than in the core, and on a case-by-case basis using a list of permissions that determine which applications may be used. This is one of the main differences from classic Internet VPN, which often grants broad network access instead of granular, application-based control.<\/p> <\/div>
Why is SD-WAN particularly well suited for cloud applications?<\/strong>
SD-WAN optimizes the data flow by always routing network traffic over the most efficient available path. As companies of all sizes increasingly rely on SaaS and cloud solutions, and users don’t care where an application is physically located, this intelligent routing delivers noticeably better performance for cloud applications than classic, statically routed networks.<\/p> <\/div>
How does SD-WAN create equal conditions for home office and mobile employees?<\/strong>
Early VPN solutions often created a two-tier society: traveling or home-office employees had significantly worse connections than colleagues at headquarters. With today’s broadband and mobile connections, equivalent bandwidths are often available outside the office too. SD-WAN uses this to give remote or mobile employees the same resources as everyone else in the organization.<\/p> <\/div>
How flexible is SD-WAN for new sites or company takeovers?<\/strong>
Because SD-WAN is not tied to a fixed infrastructure, it can adapt quickly to new requirements. New locations can be integrated into the corporate network without complications, and company takeovers can be realized quickly from a technical standpoint as well. SD-WAN grows with the company’s requirements and evolves in line with market conditions and customer needs, instead of dictating a rigid infrastructure.<\/p> <\/div>
How does SAVECALL support the introduction of SD-WAN?<\/strong>
SAVECALL supports companies in the planning, introduction and optimization of SD-WAN networks, for greater efficiency, security and growth. Rather than evaluating individual providers in isolation, SAVECALL compares suitable SD-WAN and SASE solutions for your sites and budget in a vendor-neutral way. This means the decision for SD-WAN doesn’t have to rely on in-house technical expertise alone.<\/p> <\/div> <\/div>\n\n\n\n
