SD-WAN
Software-Defined Wide Area Network, or SD-WAN, simplifies the management and operation of a wide area network (WAN). It uses software-defined networking (SDN) principles to dynamically direct traffic across the WAN, optimizing the use of available network resources.
There are many versions of SD-WAN available in the market, and they differ in their features and capabilities. Not all SD-WAN solutions are alike. By understanding your unique requirements, we can assist in selecting the best fit for your organization.
Below are some common benefits of SD-WAN solutions.
Improved Performance
SD-WAN can optimize the performance of applications by dynamically choosing the best path for data traffic based on factors like latency, packet loss, and bandwidth. This can lead to improved application performance and user experience.
Cost Efficiency
SD-WAN can often reduce costs by enabling organizations to use multiple types of network connections, including DIA, broadband, MPLS, and LTE, based on specific requirements of applications. This flexibility can lead to cost savings compared to traditional, more rigid networking solutions.
Scalability
SD-WAN allows businesses to easily adapt to changes in network requirements. This is particularly beneficial for organizations with growing or changing network needs.
Centralized Management
SD-WAN allows centralized management and control of network traffic. This makes it easier for IT teams to configure and manage the network, reducing the complexity of traditional wide area networks.
Quick Deployment & Flexibility
SD-WAN solutions are generally easier and quicker to deploy than traditional WAN architectures. They offer flexibility in terms of connectivity options and can adapt to the evolving needs of a business.
Increased Reliability & Redundancy
SD-WAN can enhance network reliability by utilizing multiple network connections and automatically rerouting traffic in the event of a network failure. This can improve overall network availability and minimize downtime.
Enhanced Security
SD-WAN often includes built-in security features such as encryption and firewall capabilities. It can also integrate with additional security solutions to help protect data as it traverses the network.
SD-WAN is a key component in the popular Gartner framework, SASE (Secure Access Service Edge), which incorporates elements of cloud security, such as Secure Service Edge (SSE) and Cloud Access Security Broker (CASB).
Secure Access Service Edge (SASE)
SASE is a framework that delivers converged network and security as a service capabilities, including SD-WAN, Secure Web Gateway (SWG), Cloud Access Security Broker (CASB), Next Generation Firewall (NGFW), and Zero Trust Network Access (ZTNA). Often delivered as a service, SASE enables zero trust access based on the identity of the device or user, combined with real-time context, security, and compliance policies.
