Digital acceleration isn’t confined to the private sector. Federal government agencies are increasingly adopting advanced technologies to enhance operations and provide better experiences to the citizens they serve. Key among them is the use of software-defined wide area network (SD-WAN) technologies, which decouple networking hardware from their control mechanisms, making IT infrastructure easier to manage using software. 

In general, SD-WAN is more flexible than traditional private wide area networks. Instead of using dedicated circuits for data exchange, it uses software to create encrypted tunnels over the Internet.

In the context of federal operations, SD-WAN solutions can meet federal government requirements, such as those included the GSA Enterprise Infrastructure Solutions (EIS) contract and FISMA compliance. Its ability to provide reliable connectivity and network management across various locations makes it a useful digital transformation tool for agencies across government. 

Here, we’ll explore five key benefits enabled by SD-WAN for government agencies, demonstrating how advanced networking can help drive efficiency, enhance security, and support the mission-critical operations of the public sector.

1. Enhancing Remote Workforce Connectivity

With remote work a common practice at the federal level, enabling secure and efficient connectivity for remote employees is paramount. IT teams are increasingly deploying SD-WAN solutions for high service availability and robust performance, leveraging advanced service optimization tools for enhanced network performance and reliability. 

An approach for these remote work use cases is to deploy lightweight, cost effective SD-WAN hardware in the home office that’s easy to install and manage. The device enables dynamic connectivity across multiple public network services using broadband or cellular. To help improve performance, it has protocol capabilities like voice over Internet Protocol (VoIP) or virtual private network (VPN) for federal data needs. 

Benefits include:

• Reliable connectivity: SD-WAN enables high-performance connections for remote workers so they can access critical applications and data.

• Enhanced cloud performance: It helps manage the performance of cloud-based applications, which is crucial for remote employees who rely on these tools for daily operations.

2. Strengthening WAN Security for Federal Locations

SD-WAN has emerged as a key tool to help enhance cybersecurity at individual government locations while maintaining the flexibility and system-wide visibility needed to adapt to the unique demands of federal operations. This technology can help deploy advanced encryption and segmentation capabilities, so that each location's network traffic is isolated and managed. 

Moreover, SD-WAN's ability to dynamically segment networks means that sensitive data can be isolated more effectively. Network segmentation can help minimize the risk of lateral movement within the network in case of a breach. By implementing SD-WAN, federal agencies can implement security protocols and operational efficiency, and otherwise manage their networks to support mission-critical activities.

Benefits include:

• Advanced encryption: SD-WAN can use sophisticated encryption protocols to help secure data transmitted over the network.

• Network segmentation: This allows for the creation of separate data flows from regular traffic, mitigating the risk of unauthorized access and data breaches.

• Dynamic path selection: SD-WAN provides real-time adjustments to traffic routing based on network conditions and security postures, enhancing overall network resilience and reliability.

3. Supporting a Cloud-first Approach

Cloud technologies are integral to federal operations today, requiring networks to serve as robust on-ramps to the cloud. SD-WAN supports this with flexible, automated, and high-performing cloud access, essential for agencies adopting a cloud-first strategy. Application-aware routing, meanwhile, ensures that traffic is directed along the most efficient paths, reducing latency and improving the performance of critical cloud-based applications.

Sometimes referred to as a cloud-first approach to SD-WAN, these use cases include organizations where users, workloads, and resources are primarily in the cloud, but some are still on-premises.

Benefits include:

• Enhanced cloud application performance: SD-WAN can help optimize the performance of cloud applications.

• Flexible connectivity configurations: It provides various connectivity options, allowing agencies to choose between internet-only or private connections for enhanced performance.

• Gradual migration support: SD-WAN allows agencies to transition smoothly to a cloud-first approach, supporting hybrid environments as more workloads migrate to the cloud. 

4. Optimizing Operational Efficiency and Scale

Every regional office and location requires reliable network connectivity. SD-WAN simplifies the deployment and management of these networks by providing a standardized approach to WAN services. This standardization helps accelerate deployment times and enables each location to receive consistent network performance. IT teams can create programmable connectivity templates that automate the configuration and setup of network services. This reduces the complexity and time required to deploy new locations, allowing agencies to scale their operations more efficiently.

Benefits include:

• Rapid deployment: SD-WAN offers programmable connectivity templates that standardize deployment processes, allowing for the quick and efficient setup of network services across multiple locations.

• Cost-effective connectivity: By leveraging cost-effective public internet connections, SD-WAN helps you manage your budget while providing reliable network performance.

• Integrated management: The integration of orchestration tools for both LAN and WLAN helps simplify security and management tasks.

5. Modernizing Global WANs for Federal Use

Many federal agencies don’t operate strictly in the US—they need the same flexibility, scalability, and visibility across borders. This use case typically involves managing diverse sites across continents, where SD-WAN’s intelligent routing and bandwidth management tools enhance digital service quality and user experience.

A large global SD-WAN usually comprises sites with private circuits coupled with other sites that run only on Internet circuits. The use case involves routing traffic to on-premises data centers as well as the cloud.

Benefits include:

• High-quality experience: SD-WAN’s intelligent routing and bandwidth resource management allow for reliable, high-performance connectivity, and help reduce congestion, latency, and packet loss.

• Simplified management: It brings end-to-end visibility and real-time bandwidth controls into a single dashboard, simplifying the management of highly distributed environments.

• Comprehensive security: SD-WAN can be combined with a suite of security services, such as 24/7 threat detection and response, firewalls, and more, to help protect the network.
