Introduction
Network technology is evolving rapidly, and businesses need to keep up with the latest trends and innovations to stay competitive and secure. Two of the most popular and promising network technologies today are SD-WAN and SASE. But what are they, and how do they differ? And more importantly, which one is right for your business?
In this blog post, we will explain the differences between SD-WAN and SASE, the benefits of each technology, and share how Vista Technology Support can help you transition to either technology through expert solution design and installation of high quality, secure and cost-effective network technology and structured cabling.
What is SD-WAN?
SD-WAN stands for Software-Defined Wide Area Network. It is a network technology that uses software to control and optimise the routing of traffic across multiple WAN links, such as broadband, MPLS, LTE, or satellite. SD-WAN enables businesses to dynamically adjust the path and priority of traffic based on the application, performance, security, and cost requirements. SD-WAN also provides centralised management and visibility of the entire WAN network, simplifying the configuration and troubleshooting of network devices and policies.
What is SASE?
SASE stands for Secure Access Service Edge. It is a network architecture that combines SD-WAN with cloud-based security services, such as firewall, web filtering, malware protection, data loss prevention, and zero-trust network access. SASE delivers these security services from the cloud, closer to the edge of the network, where the users and devices are located. SASE enables businesses to apply consistent and granular security policies to all network traffic, regardless of the location, device, or application. SASE also reduces the complexity and cost of managing multiple security solutions and vendors, as well as the latency and bandwidth consumption of backhauling traffic to a central security gateway.
What are the benefits of SD-WAN and SASE?
Both SD-WAN and SASE offer significant benefits for businesses that need to support a distributed and dynamic workforce, as well as a diverse and demanding application portfolio. Some of the common benefits of both technologies are:
- Improved network performance and user experience, by optimising the routing and prioritisation of traffic based on the application and network conditions.
- Increased network agility and scalability, by enabling rapid and flexible deployment of new sites, users, devices, and applications, without compromising the network quality and security.
- Reduced network cost and complexity, by leveraging cheaper and more available WAN links, such as broadband and LTE, and by simplifying the management and maintenance of network devices and policies.
However, there are also some differences between SD-WAN and SASE, and each technology has its own advantages and disadvantages, depending on the business needs and goals. Some of the key differences are:
- SD-WAN focuses more on the network performance and optimisation, while SASE focuses more on the network security and compliance.
- SD-WAN requires additional security solutions and vendors to protect the network traffic, while SASE provides integrated and comprehensive security services from the cloud.
- SD-WAN relies more on the physical network devices and appliances, while SASE relies more on the cloud-based network services and platforms.
Which one is right for your business?
The answer to this question depends on several factors, such as your current network infrastructure, your future network requirements, your budget and resources, and your risk appetite and tolerance. There is no one-size-fits-all solution, and each business needs to evaluate the pros and cons of each technology and find the best fit for their specific situation and objectives. However, some general guidelines are:
- If you already have a robust and reliable WAN network, and you are mainly looking for a way to improve the network performance and efficiency, SD-WAN might be a good option for you.
- If you have a diverse and distributed network environment, and you are mainly looking for a way to enhance the network security and compliance, SASE might be a better option for you.
- If you have a hybrid and dynamic network scenario, and you are looking for a way to balance the network performance and security, a combination of SD-WAN and SASE might be the optimal solution for you.
