The Benefits of SD-WAN Technologies for Your Business

SD-WAN technologies offer tangible advantages for businesses. Let's explore some of the most significant:

• Improved application performance: SD-WAN technologies prioritize bandwidth for critical applications, reducing latency and improving user experience. Businesses can ensure that essential applications like video conferencing and CRM systems operate smoothly, regardless of network congestion. This application-aware routing is a game-changer for productivity.

• Reduced WAN costs: SD-WAN technologies enable businesses to leverage lower-cost broadband internet connections instead of relying solely on expensive MPLS circuits. This can lead to significant savings in WAN costs, especially for organizations with multiple branch locations. These savings can be reinvested into other areas of the business.

• Increased network agility: SD-WAN technologies allow businesses to quickly adapt their networks to changing needs. New branch locations can be brought online quickly, and network policies can be updated centrally without requiring manual configuration at each site. This agility is critical for fast-growing companies.

• Enhanced security: SD-WAN technologies often include built-in security features like firewalls, intrusion detection, and VPNs, providing a layered approach to network security. These features can help businesses protect their networks from cyber threats without adding complexity. This layered security posture is paramount in today's threat landscape.  

Addressing the Challenges of SD-WAN Implementation

While SD-WAN technologies offer numerous benefits, businesses should also be aware of potential challenges:

• Complexity of deployment: Implementing SD-WAN technologies can be complex, especially for organizations with large and distributed networks. Careful planning and execution are essential to ensure a smooth transition. It's vital to have a clear understanding of your network requirements and to choose the right SD-WAN technologies solution for your needs.

• Security concerns: SD-WAN technologies can introduce new security risks if not properly configured and managed. Businesses need to ensure that their SD-WAN technologies deployments are secure and compliant with industry regulations. This includes implementing strong security policies and regularly monitoring the network for threats.

• Integration with existing infrastructure: SD-WAN technologies need to be integrated with existing network infrastructure, which can be challenging if the infrastructure is outdated or complex. Careful planning is needed to ensure that the SD-WAN technologies solution integrates seamlessly with your existing network.

• Skills gap: Implementing and managing SD-WAN technologies requires specialized skills, which may not be readily available within the organization. It's important to invest in training for your IT staff or to partner with a managed service provider that has the necessary expertise.  

Exploring SD-WAN Deployment Models

Businesses have several options for deploying SD-WAN technologies:

• DIY SD-WAN: In this model, the business purchases and manages all SD-WAN technologies components themselves. This option offers the most control but requires significant technical expertise. It also requires a significant investment in time and resources.

• Fully managed SD-WAN: In this model, a managed service provider (MSP) like Aera handles all aspects of the SD-WAN technologies deployment, including planning, design, implementation, and ongoing management. This option offers the least amount of burden on internal IT staff. This model can free up your IT staff to focus on other strategic initiatives.

• Co-managed SD-WAN: This model combines elements of DIY and fully managed SD-WAN. The business retains control over certain aspects of the deployment while outsourcing others to an MSP. This option allows businesses to leverage the expertise of an MSP while still maintaining some control over their network.

• Managed CPE SD-WAN: The business owns the hardware, but the SD-WAN technologies solution is managed by a service provider.

• SD-WAN as a service (SD-WANaaS): The business consumes the SD-WAN technologies solution as a cloud-based service, paying a monthly fee for access to the platform and its features.

Aera provides both managed and co-managed SD-WAN technologies solutions, offering businesses the flexibility to choose the model that best meets their needs. Our Professional Services team can assess your current infrastructure and provide tailored recommendations.

SD-WAN Security: Key Considerations

Security is a critical consideration when deploying SD-WAN technologies. Key best practices include:

• Importance of integrated security features: Choose SD-WAN technologies solutions that include built-in security features like firewalls, intrusion detection, and VPNs. These integrated features can simplify security management and reduce the risk of misconfiguration.

• Role of firewalls and intrusion detection systems: Ensure that firewalls and intrusion detection systems are properly configured and integrated with the SD-WAN technologies solution. These systems should be constantly monitored and updated to protect against the latest threats.

• Need for ongoing security monitoring and management: Implement a robust security monitoring and management program to detect and respond to security threats. This program should include regular security assessments, vulnerability scanning, and incident response planning.

Aera's Cyber Security offerings, including network and perimeter security, provide comprehensive protection for SD-WAN technologies deployments, ensuring that your network remains secure. We understand the unique security challenges of SD-WAN technologies and can help you implement a layered security approach that protects your data and applications.

SD-WAN and Complementary Technologies

SD-WAN technologies can be integrated with other technologies to enhance their effectiveness:

• SD-WAN and firewalls: SD-WAN technologies can be integrated with firewalls to provide a layered approach to network security. This integration allows businesses to enforce consistent security policies across their entire network.

• SD-WAN and 5G: SD-WAN technologies can be used to optimize traffic over 5G networks, providing improved performance and reliability. This is especially important for businesses that rely on mobile devices and applications.

Furthermore, SD-WAN technologies also work well with other systems, like SASE (Secure Access Service Edge). A SASE framework means that SD-WAN and other functions are brought together under a single umbrella. This may well become a standard part of data security in the future.
