SD-WAN technology has enabled businesses to enhance the user experience and productivity. Whether startups, SMEs, or big organizations, every business entity is switching to SD-WAN to build its brand identity.

However, they are making typical mistakes, such as failing to allocate a dedicated IP address while deploying SD-WAN technology. This article discusses the four common mistakes that can be avoided to gain multiple benefits.

Four common SD-WAN mistakes

SD-WAN (software-defined wide area networks) combines broadband, MPLS, and LTE technology perfectly. It can be super beneficial for your business only if deployed correctly. Here’s a list of what not to do when installing SD-WAN

1. Ignoring SD-WAN security needs

The most common mistake is the assumption that SD-WAN is inherently secure. The truth is that this technology allows integration with security apps or features to enhance protection levels. Installing SD-WAN alone won’t help your business.

Some SD-WANs may already be configured with security features like Next-Gen firewall inspections, IRL filtering, etc., while others may not. So, businesses must carefully plan to configure the SD-WAN with their existing infrastructure to mitigate the risk of security breaches.

2. Deploying SD-WANs using wrong approach

SD-WAN may offer numerous benefits like scalability and reliability, but implementing this technology into your business is complex. SD-WANs can deliver exceptional results when deployed with an end-to-end approach. Companies can’t rely only on SD-WAN’s technical capability. It takes a clear strategy and action plan to avoid unnecessary expenses. Before deploying SD-WANs, make sure to consider and understand:

  • The functionality of existing WANs and newly installed SD-WANs.
  • Training programmes for employees
  • Process to Control and Manage SD-WAN Installation.
  • Expected Performance outcomes
  • The best provider to accommodate the current traffic.

When implementing SD-WANs, it is always advisable to have a backup plan.

3. Wrong choice of vendors

With plenty of SD WAN providers available on the market, choosing the right one can be quite complicated. Not all vendors possess the skills to understand the customer’s demands and meet the desired expectations. An initial SD-WAN setup can be challenging, but it can yield numerous benefits if implemented successfully.

Technical proficiency is not the sole parameter when selecting a vendor. Look for security features, QoS (quality of service), intuitive user interfaces, and others to optimize the performance of existing network infrastructure.

4. Inadequate knowledge of application requirements

Companies must track and monitor network performance before installing SD-WANs into their current network. SD-WAN must be configured with bandwidth and latency policies to prioritize the performance of ongoing applications. An under-optimized design strategy can prove to be a critical SD-WAN installation mistake.

It can degrade user experience, security, compliance, and network performance. Organizations must identify application requirements to reap the maximum benefits. This critical mistake often leads to resource misallocation, compliance issues, and poor network performance.


A well-planned SD-WAN deployment strategy is essential to avoid these critical mistakes that can degrade the overall network performance. Remember, switching from traditional WANs to SD-WANs takes work. Only professional SD-WAN providers can simplify installation and help take your business to new heights.
