WAN optimizer

WAN optimizer

(also WAN optimization, WAN acceleration)

WAN optimizer definition

A WAN optimizer refers to a networking apparatus or software designed to enhance the performance and effectiveness of wide area networks (WANs) by fine-tuning data transmissions between devices. This optimization is achieved through the reduction of latency, minimization of packet loss, and acceleration of data transfer rates. To optimize network performance across applications, data transfers, and additional services, WAN optimizers employ a range of methods, including data deduplication, compression, caching, and traffic shaping.

WAN optimizer examples

  • Hardware-based: Physical devices on the network edge optimizing WAN traffic, supporting various techniques and robust security features.
  • Software-based: Applications on devices or servers for flexible, cost-effective network optimization without specialized hardware.
  • Virtual: Cloud-based services for WAN optimization without on-premises hardware or software installations.

WAN optimizer pros and cons


  • Improved application performance across the network.
  • Reduced bandwidth costs.
  • Enhanced user experience for remote and branch office workers.


  • Higher upfront costs for hardware-based solutions.
  • Potential compatibility issues with some network configurations.
  • Need for ongoing maintenance and management.

Tips for choosing a WAN optimizer

  • Consider your network size, traffic volume, and specific optimization requirements.
  • Evaluate the compatibility of the WAN optimizer with your existing network infrastructure.
  • Compare the costs and benefits of hardware-based, software-based, and virtual WAN optimizers.
