Unwrapping SD-WAN and SASE: 

Why these transformative solutions should be on your Tech Wish List

Organizations are looking for efficient and secure connectivity solutions as the digital landscape evolves beyond traditional MPLS. Two technologies, Software-Defined Wide Area Networking (SD-WAN) and Secure Access Service Edge (SASE), stand out in reshaping network paradigms. This holiday season, consider unwrapping these transformative gifts for your organization. 

SD-WAN: Streamlining Connectivity 

SD-WAN leverages software to centralize network control, optimize traffic, increase bandwidth efficiency, and reduce costs. It links locations to an organization’s secure network using a mix of cloud and hardware infrastructure. SD-WAN is cost-effective and efficient, providing reliable connections and leveraging existing infrastructure.  

Pros of SD-WAN: 

  • Ease of management and Centralized Control 
  • ROI on private circuits and MPLS 
  • Flexibility of mix WAN configurations 
  • Improvements in security 
  • Scalability and Agility  

SASE: Elevating Security in Connectivity 

SASE, blends SD-WAN functionality with enhanced security features. It connects endpoints securely using cloud-based services like CASB, FWaaS, SPD, ZTNA, and SWG. SASE addresses SD-WAN limitations, offering a consolidated, cloud-delivered service that simplifies management and enhances security. 

Pros of SASE: 

  • Improved levels of performance optimization and QOS for Cloud and SaaS applications 
  • Ideal for virtual connections, replacing VPNs 
  • Centralized cloud management 
  • Infinitely scalable  
  • Enhanced level of network and user security 

Differences and Similarities: 


  • Both use virtual overlay networks for routing and traffic optimization 
  • Both offer high availability connection to the cloud and greater internet 
  • Centralized control from any location 


  • SD-WAN focuses on the organization’s data center, while SASE deploys via the cloud 
  • SD-WAN deals with traffic functions individually, whereas SASE provides an overall solution 
  • SD-WAN’s security is secondary, while SASE integrates security with network optimization 
  • SD-WAN is managed on-premises or via the cloud, while SASE is a cloud-delivered service 

Choosing Between SASE and SD-WAN: 

Organizations must review the topology of the current infrastructure and if they will move to a cloud-first initiative. SD-WAN’s edge-based architecture shines as a clear-cut winner when infrastructure is maintained onsite. When cloud-based applications like Microsoft Teams and Salesforce are coupled with cloud infrastructure like Azure or AWS, SASE outperforms many of the standalone SD-WAN offerings. In addition, an organization’s initiative in security also plays a large role in deciding which platform is the right fit. With SASE providing native security it is a heterogeneous solution for customers that want to combine performance with security. 

SASE: Future of SD-WAN and Security? 

With its focus on the service edge, SASE may evolve to replace SD-WAN entirely. Legacy architectures centered around data centers face inefficiency with shifting technologies like SaaS applications, cloud infrastructure, and remote workforce. SASE’s efficient and secure approach based in the cloud, could be the future norm. 


In a world where data flows freely in the cloud, SD-WAN and SASE offer valuable connectivity solutions. For your organization’s Christmas wish list, consider these technologies to unwrap enhanced efficiency, security, and adaptability. As cloud-based models redefine the network edge, the choice between SD-WAN and SASE depends on your specific needs, deployment preferences, and security requirements. Make your decision wisely and enjoy the gift of optimized connectivity this holiday season.
