Networking & Security Converging in Cloud



A question arises: are you ready for this? The rise in remote working and distributed users accessing cloud-hosted applications means that the enterprise perimeter is no longer limited to users within the company site. 52% of the respondents said in a survey that they have deployed Cloud Infrastructure as a Service and 42% said they currently use hybrid cloud. While cloud adoption continues to grow, enterprises have generally struggled to implement and maintain a secure, high-performing WAN that allows for efficient access to cloud-based applications across their user base. If you consider the distributed nature of enterprise applications, and now the increasingly distributed nature of employees working from home, the traditional branch networking method of backhauling traffic (from users and devices) to a centralized location is highly inefficient.

Secondly, there is an emerging nomenclature, SASE (Secure Access Service Edge) aims to address the need for a centralized, software-defined security architecture when the apps and users are highly distributed. SASE combines the flexibility of SD-WAN with a full suite of virtual security services, all delivered from the cloud. Furthermore, the rise in remote working and distributed users accessing cloud-hosted applications means that the enterprise perimeter is no longer limited to users within the company site. Think about it: if your applications are in the cloud, and the users are at home or at a branch location (spread across the globe), why is your organization’s security set up at the headquarters location? The traditional model is time-consuming with subpar performance and a poor user experience. Secure Access Service Edge, or SASE, aims to address the need for a centralized, software-defined security architecture when the apps and users are highly distributed.
