The world of network technology continues to evolve rapidly. Two of the key concepts receiving significant attention today are SD-WAN (Software-Defined Wide Area Network) and SASE (Secure Access Service Edge).
In this article, I aim to explain the latest insights from renowned research companies such as Gartner and others about these technologies and what they mean for modern businesses.
What is SD-WAN?
SD-WAN stands for Software-Defined Wide Area Network. It is a technology that enables businesses to dynamically manage and optimize their network traffic using software. Rather than relying on traditional network infrastructures, SD-WAN allows the combination of various connection types such as DSL, fiber, Starlink, 4G/5G, and MPLS to enhance performance and gain more insight into configurations.
Benefits of SD-WAN
Costs
By using cheaper internet connections alongside or instead of MPLS, you can often achieve significant cost savings.
Improved performance
Carefully evaluate the Total Cost of Ownership (TCO) of your network, including initial implementation costs, licenses, maintenance, and operational expenses.
Flexibility
It is much easier to add new locations and scale network capacity up or down using SD-WAN.
Insights from Gartner about SD-WAN
According to Gartner, the adoption of SD-WAN continues to grow rapidly. They predict that by the end of 2024, more than 60% of businesses will have implemented SD-WAN. The primary drivers behind this trend include the desire to better support cloud applications and the need for more flexible network management.
What is SASE?
SASE, or Secure Access Service Edge, is a concept introduced by Gartner in 2019. SASE integrates network and security functions into a single, cloud-based platform. This means that both network connections and security are managed from the cloud, providing an integrated approach to network management and security.
Benefits of SASE
Integrated security
SASE offers a wide range of security features, including Zero Trust Network Access (ZTNA), Secure Web Gateways (SWG), and Cloud Access Security Brokers (CASB).
Simple management
Combining network and security services into one platform simplifies management.
Scalability
Businesses can easily scale up or down, depending on their needs, thanks to the cloud-based architecture.
Improved user experience
SASE optimizes network performance and provides secure, fast access to applications, regardless of the user’s location.
Insights from Gartner and other research firms about SASE
Gartner predicts that by 2025, at least 60% of enterprises will have an explicit SASE strategy, compared to only 10% in 2020. This rapid growth is driven by the increase in remote work and the shift towards cloud-based services. Other reputable research firms, such as Forrester and IDC, support these findings and emphasize that SASE will play a crucial role in the future of network and security management.
How do you benefit from SD-WAN and SASE?
Evaluation of the current infrastructure
Companies should start by evaluating their current network infrastructure and security solutions to understand where improvements can be made.
Determine the needs
Identify the specific needs of the business, such as cost savings, improved security, or better support for cloud applications.
Choose the right solution
It is crucial to choose vendors that offer robust and integrated SD-WAN and SASE solutions. Pay attention to factors such as flexibility, scalability, and security capabilities.
Plan and implement
Develop a detailed plan for implementing SD-WAN and SASE, including staff training and thorough testing to ensure the solutions work well within the existing infrastructure.
Conclusion
SD-WAN and SASE are revolutionary technologies that help businesses manage their networks more efficiently, securely, and cost-effectively. With the continuous growth of cloud applications and remote work, these solutions are becoming increasingly relevant. Insights from reputable research firms like Gartner, Forrester, and IDC underscore the importance and benefits of these technologies. By embracing these advancements, businesses can better position themselves for success in the future.
