Over the last 20 years of enterprise computing, we've seen big changes in work environments and IT setups.
At the turn of the millennium, most employees worked at headquarters or in a branch office, and most software ran from on-site servers. Networks were designed with centralized architecture, with all traffic being routed through the corporate data center over MPLS or VPN. As a result, the entire security stack could be deployed on-premises in a single place.
Remote work has been around for decades (the term "telecommuting" was coined in 1973 by a NASA engineer), but it gathered momentum in the 2000s as laptops and Wi-Fi became commonplace while startup culture gained traction. Employers started recognizing the need for remote-work guidelines and digital nomads evangelized the lifestyle of "working from anywhere."
Around the same time, cloud computing took shape with the reinvention of virtual machines and the emergence of application service providers and multi-tenant SaaS providers in the late 1990s. Public cloud services and productivity apps emerged in the 2000s and exploded in the 2010s, driven by cost savings and flexibility.
As workers have moved out of the office and computing has moved into the cloud, there's been a steep rise in internet traffic, and more work is being done off-network. Backhauling this traffic through MPLS lines and VPNs is more expensive and leads to performance problems. But direct internet access is risky because it bypasses the central security stack.
In the wake of this transformation in work and IT environments, your organization is likely running into challenges in two specific areas: securing your remote workers and securing your network edge. Today's answer to these challenges is a redesigned network architecture. Secure access service edge (SASE) incorporates a software-defined WAN, bringing networking and security together in the cloud where computing is happening.
You can get a thorough overview of SASE architecture by reading the e-book, The House That SASE Built.
Let's delve into the specifics of these two use cases and the SASE and SD-WAN benefits for each.
Use case 1: Secure remote workers
Protecting employees, customers, and other users from cyber threats while providing seamless connectivity is challenging on several fronts:
According to the three Cs, an integrated approach for SASE, here's how SD-WAN helps address these challenges, delivering secure consistent access to apps and data from anywhere:
Use case 2: Secure edge
Multicloud environments, which use cloud services from more than one public cloud provider, are driving the need to secure the cloud and access edge.
Organizations adopt multicloud strategies in order to hit their business objectives and take advantage of cost savings and innovation while reducing risk. With distributed users needing to access applications in multiple clouds from anywhere, at any time, organizations must provide security closer to the user and edge to minimize network latency and stay agile.
Finding an optimal balance between protection and performance is challenging in cloud environments:
Again, SASE and SD-WAN solve these problems, safeguarding the network edge.
