In recent years, more and more enterprises in Singapore, or even in the global scope, are using SASE SD-WAN to ensure their network environment. Businesses also adopt SD-WAN techniques in network security and further improve the cybersecurity of their organizations’ private networks to allow safer data transmission. It is an indispensable part of businesses in the digital era. In the following article, we are going to explore more about SASE SD-WAN.
What is SASE SD-WAN?
SASE is a short form of “Secure access service edge”. It is an architecture that could help users enhance the security level of the target network. On the other hand, SD-WAN stands for Software-defined wide area network. Combining the two techniques, one of the biggest advantages is that it allows users to adopt cloud security solutions. It also allows businesses to scale up or down according to their needs and business scale. In other words, SD-WAN can be used by both large enterprises and small businesses because it is scalable to fit their needs. Its flexibility has offered businesses more room to optimize cost efficiency and maximizes the use of SD-WAN. It also has a wide range of applications, from data backup and disaster recovery to load balancing, security, and traffic management.
SASE & SD-WAN: Similarities
SASE and SD-WAN are very similar in some aspects. For example, both of them could enhance the security and networking of a company. The benefits they bring could be similar too, including the scalability and flexibility we have mentioned above. It also helps companies to cut costs.
SASE vs SD-WAN: Differences
There are some main differences between SASE and SD-WAN. First, about the usage of the cloud, SASE would be using cloud computing advantages to enhance network security. It could be used with any other cloud services, such as public clouds, private clouds, and hybrid clouds. It would offer connections breaking geographical limitations from the users to the resources available on the cloud. On the other hand, SD-WAN is not cloud-based, even though it could also be connected to cloud resources. Second, SASE focuses on the cybersecurity aspect, while sd-wan is focusing on network virtualization. It could create individual services for all the locations involved in the plan.
How do businesses choose SASE SD-WAN solutions?
Nature of services
SASE would be performing better in terms of offering comprehensive cyber security to businesses. It could be used to ensure Zero Trust security and protect businesses from DDoS attacks. If your company is looking for a more scalable network virtualization solution, SD-WAN is your choice. However, these two are not contradicting each other. You could integrate the two for a higher resilient SD-WAN solution with SASE.Business size
In common practice in Singapore, SMEs would use SD-WAN more for higher control over the networks. As the data traffic is not so large that to the extent that it would cause severe security problems for businesses. When the business size is bigger, the data traffic might be hard for the companies to handle. SASE could help companies to lower managerial difficulties and enhance network safety for enterprises. Hence, SASE is more commonly used by larger companies.
