Security Becomes an Important Consideration for SD-WAN

1. The popularity of SD-WAN


In recent years, SD-WAN has become popular due to advantages such as price, elasticity, and ease of deployment compared to MPLS (Multi-Protocol Label Switching) traffic distribution technology.


Centralized visibility and manageability, as well as a dramatic increase in the overall performance of WAN links, make employees more productive. However, if the end users of branch offices are allowed to directly connect to the public network or use cloud services, security issues will emerge, resulting in the risk and complexity of implementing SD-WAN.


2. Security defense of SD-WAN appliance


At the end of 2018, a survey of 250 European and American companies led by the Enterprise Management Association showed that organizations that deployed SD-WAN in their branches were more likely to suffer from the risk of data leakage (approximately -1.3 times that of the organization of the WAN). Because these institutions rely purely on the security functions of the SD-WAN appliance itself for defense, without cooperating with other security mechanisms.


A typical SD-WAN generally provides security functions such as dynamic packet filtering firewall (Stateful Firewall), network segmentation, and site-to-site tunneling. But it will not provide further security functions, such as generation wall, intrusion detection, data leakage prevention and UTM, etc. Another thing to note is that it is difficult to easily integrate ordinary SD-WAN with the original security infrastructure of the enterprise.


Today's enterprise users have begun to realize the importance of security. A recent joint survey by IDG and Masergy, an SD-WAN provider, shows that 81% of the respondents said that security is the most critical factor to consider when purchasing SD-WAN products. Such as sd wan in manufacturing and sd wan for small business.


Professional SD-WAN providers (referring to network equipment vendors) know this very well, so they have cooperated with professional security vendors, such as firewall or cloud security vendors, to provide integrated security functions.


There is no doubt that global enterprises are firmly adopting more flexible, cost-effective and cloud-connected infrastructure as an important solution to simplify the digital transformation journey.


Concepts such as sd wan managed services, SASE, ZTNA, and Multi-cloud have become the hottest topics in the industry. How can enterprises choose a reliable service partner to implement their own intelligent connectivity, thereby reducing costs, increasing visibility and gaining performance gains?
