The landscape of modern organizations has undergone a significant transformation, ushering in a new era of borderless operations. This shift is characterized by distributed users and devices, the rise of IoT ecosystems, multiple company locations, and the widespread adoption of cloud environments. In this rapidly evolving landscape, organizations require new access control requirements and a flexible, dynamic network infrastructure capable of delivering both performance and security anywhere, including in the cloud and at any time.
The Emergence of SD-WAN
To address the need for reliable connectivity and improved performance, the concept of Software-Defined Wide Area Networking (SD-WAN) was born. SD-WAN enables enterprise sites to connect directly to distributed on-premise and Software as a Service (SaaS) applications, ensuring consistent performance and security over commodity broadband links. It eliminates the dependence on costly and rigid MPLS networks, enabling organizations to take advantage of more affordable and versatile broadband connections.
Limitations of SD-WAN
While SD-WAN has proven to be a significant advancement in networking, its capabilities were not designed to address the accelerating cloud and IoT adoption or the distribution of the workforce. These changes have created new networking and security needs. SD-WAN alone falls short in providing comprehensive solutions for managing distributed workforces and securing cloud and IoT connections effectively.
The Next Era of Networking
The future of networking lies in the convergence of networking and security, based on context-aware zero trust principles. This next era of networking recognizes that trust cannot be automatically granted based solely on user credentials or network location. Zero trust-enabled, context-aware SD-WAN leverages contextual policies that consider applications, users, devices, and associated risks to deliver high-performance networking and security without trade-offs.
Collaboration Between Networking and Security Teams
The success of zero trust-enabled SD-WAN hinges on close collaboration and integration between networking and security teams. By working together, these teams can leverage each other’s expertise to deliver consistent security and improve the quality of experience for end-users. The networking team can tap into the granular and context-aware insights provided by the security team to implement adaptive policies that align with organizational security requirements.
Benefits of a Software-Based SASE Agent
A key component of the next era of networking is the adoption of a Software Access Service Edge (SASE) agent. This software-based solution combines the advantages of SD-WAN and Secure Service Edge (SSE), providing cutting-edge security and connectivity. By deploying a SASE agent, organizations can establish granular and dynamic access policies, eliminating the need for Virtual Private Networks (VPNs) on employee devices and reducing the complexities of remote hardware management logistics. Additionally, administrative burdens are alleviated, resulting in enhanced network efficiency.
Zero Trust, Context-Aware SD-WAN, and SASE
Zero trust, context-aware SD-WAN, and SASE together create an intelligent network meticulously designed for modern businesses. These solutions address the challenges posed by borderless organizations, delivering adaptive security measures that align with the evolving threat landscape. Context-aware policies implemented through zero trust principles ensure that applications, users, and devices are thoroughly vetted and authorized before accessing network resources.
Growth and Future Prospects of SASE
The increasing adoption of zero trust-enabled SD-WAN and SASE speaks to the significance of this paradigm shift. According to Gartner, the Security Access Service Edge (SASE) market is projected to reach $15 billion by 2025, with a compound annual growth rate (CAGR) of 36% per year. This rapid growth reflects the industry’s recognition of the necessity and value of converging networking and security technologies to meet the demands of borderless organizations.
In a world where organizations are no longer confined by physical borders, networking operations must evolve to ensure optimal performance and security. The emergence of zero trust-enabled SD-WAN and SASE heralds a new era where networking and security converge, leveraging context-aware policies to deliver consistent security and improved user experience. With the market for SASE expected to grow exponentially, organizations should embrace this intelligent network design to thrive in the modern business landscape.
