In the ever-changing world of business networking, where terms like ZTNA and SASE dominate conversations, it's crucial not to overlook the reliable solution - SD-WAN. As companies deal with the aftermath of increased remote work during the pandemic and growing network demands at branch locations, the deployment of Software-Defined Wide Area Network (SD-WAN) has become common. Amidst the hype for cutting-edge technologies, it's wise to revisit the security of your SD-WAN solution.

The Evolution of SD-WAN and Its Increasing Significance

Initially embraced for its ability to optimize traffic over wide-area networks (WAN), SD-WAN has gone beyond its traditional role. Modern businesses now use SD-WAN to transform not only WAN but also local area networks (LAN), wireless LANs, and wireless WANs (WWAN). This transformation is crucial in simplifying the overall infrastructure architecture and management, making SD-WAN a key component in broader network transformation.

1. Going Beyond WAN Transformation

Businesses, recognizing the efficiency benefits of software-defined solutions, aim to extend this transformation to their entire infrastructure. SD-WAN becomes a critical element in integrating diverse components, providing a seamless user experience, and simplifying overall management.

2. Operational Efficiency in Multi-Cloud Environments

The multi-cloud approach, where companies utilize different cloud providers for various needs, has become common. Despite its advantages, managing and securing a multi-cloud environment is complex. SD-WAN emerges as the preferred solution for multi-cloud organizations, offering an application-aware network infrastructure with consistent policies, simplifying management, and reducing costs.

3. Building the Foundation for SASE

Secure Access Service Edge (SASE), the integration of networking capabilities like SD-WAN with cloud-delivered security services, is a prevailing trend. Building a comprehensive SASE solution can be challenging, but for organizations already using SD-WAN, it becomes the cornerstone of their SASE approach. This emphasizes the need for a secure and robust SD-WAN solution.

Ensuring the Security of Your SD-WAN: Key Considerations

While the benefits of SD-WAN are clear, its security should not be an afterthought. Here are three crucial considerations to ensure the security of your SD-WAN:

1. Integration of Security and Networking

A common mistake in SD-WAN deployments is adding security as an afterthought, creating a separate solution. Ideally, security and networking should be seamlessly integrated from the beginning. Choose a solution that addresses both aspects cohesively, ensuring a unified approach to networking and security.

2. Traffic Inspection with Minimal Performance Impact

As cyber threats become more advanced, inspecting encrypted traffic is essential. SD-WAN solutions should offer robust traffic inspection without compromising user experience and network performance. Deep packet inspection capabilities are crucial in identifying and mitigating potential threats hidden within encrypted traffic.

3. Scalability without Compromising Security

The scalability of an SD-WAN solution should be a source of strength, not stress. Look for a solution that can dynamically scale networking and security across various sites. Additionally, choose an SD-WAN solution with user-friendly management across sites and compatibility with a distributed control architecture.

The Role of SD-WAN Security in Cybersecurity Strategy

In the dynamic field of cybersecurity, SD-WAN should be seen as a foundational pillar. While discussions around ZTNA and SASE are buzzing in the industry, it's important not to neglect existing solutions. The capabilities of products evolve rapidly, highlighting the need to continuously enhance SD-WAN offerings with state-of-the-art security measures.

In this pursuit, partnering with a vendor who prioritizes consistent refinement and integrates cutting-edge security measures is crucial. Your SD-WAN deployment should be protected to effectively safeguard critical business assets.
