SD-WAN and SASE:
The new landscape
of networking

As the world rapidly adopts a cloud-first strategy, the IT landscape has become significantly different. Enabling secure access to applications wherever users may be is a significant priority. While delivering speed and agility, the multicloud environment creates challenges such as an expanded attack surface and less control over the user experience. Cisco Catalyst SD-WAN helps you address these issues.

With the power of multicloud access and integrated security, businesses can improve performance, reduce costs, and protect critical assets. As a cloud-native WAN overlay, Catalyst SD-WAN ensures application performance and adapts to changing conditions--with minimal manual intervention. Catalyst SD-WAN is the foundation for a secure access service edge (SASE)-enabled architecture and offers the ability to extend IT's visibility beyond the corporate network and into the internet and cloud. 

Today, your network has to work harder than ever to deliver the required user experiences over the cloud. With SD-WAN Cloud OnRamp, you can enable applications on any platform with consistent, predictable performance in minutes. Software-defined WAN (SD-WAN) helps you optimize your wide area network, which means better experiences for customers and employees.

Cloud OnRamp for software as a service (SaaS) uses real-time analytics to steer users onto the best-performing path for optimal application performance for applications like Microsoft 365, Salesforce, and other cloud-based apps. Enjoy up to 40 percent faster performance for Office 365 with Catalyst SD-WAN.²

Cloud OnRamp for infrastructure as a service (IaaS) delivers seamless, automated connectivity to the public cloud. The cloud networking solution simplifies workflows for Amazon Web Services (AWS), Azure, and Google Cloud, including application-aware policies that allow real-time policy enforcement for cloud and on-premises solutions. IaaS spend is projected to grow by 24 percent CAGR to reach $74B by 2022.³

In addition, Cloud OnRamp automates on-demand connectivity to multiple sites and to the world's leading cloud provider networks through software-defined cloud interconnect (SDCI) providers like Equinix and Megaport. 

As organizations and users become more distributed, the demand for anywhere, anytime access to applications has resulted in the transformation of networks to deliver uninterrupted connectivity while maintaining security. To protect anywhere, anytime access, organizations need to provide security closer to the user and edge to support network agility and minimize network latency.

Catalyst SD-WAN provides full-stack multilayer security capabilities for both on-premises and cloud. It bridges organizations' current security deployments with their SASE rollout by providing consistent security policy enforcement that can be deployed and managed anywhere. 

Data breach costs rose from $3.86M to $4.24M, the highest average total cost in the history of data breach report.

Applications and users are more distributed than ever, and the internet has effectively become the new enterprise WAN. As organizations continue to embrace the internet, cloud, and SaaS, network and IT teams are challenged to deliver reliable connectivity, application performance, and security over networks and services they don't own or directly control.

Network teams often carry the burden of proving the network innocent when something goes wrong. Application issues might manifest themselves as network issues. Service disruptions can lead to endless finger-pointing. The resulting cycles pinpointing the source of issues can lead to prolonged service interruptions that ultimately damage the revenue and reputation of the business.

Enterprises can expedite ThousandEyes agent deployment with Cisco Catalyst SD-WAN Manager integration to quickly pinpoint the source of issues, get to resolution faster, and manage the performance of what matters. Cisco Catalyst SD-WAN Analytics correlates application behavior and quality of experience (QoE) with the underlying SD-WAN network, translating real-time data into visualized insights.

Managing branch locations has always been a major challenge within traditional WAN architectures and deploying security across global locations adds complexity. This makes consistent policy enforcement a distant goal, made even more unattainable when a policy change needs to be rolled out across all sites. SD-WAN makes consistent policy not only possible but seamless, with automated integration with Cisco Umbrella.

It doesn't matter if you're managing tens or thousands of locations; SD-WAN simplifies network management. With a single WAN fabric, all policies and configuration can be centrally managed, even across multicloud environments. Cloud security can be enabled to thousands of sites within minutes. The outcome is true simplicity at an enterprise scale.

In addition, relying on the internet for enterprise cloud access on a global level adds even more complexity. Link quality and the ease of doing business with internet service providers can vary from region to region. Luckily, Catalyst SD-WAN is able to scale your business, thanks to its support for multigigabit wireless. To do this, the Cisco Catalyst 8000 Edge Platforms Family offers multigigabit ethernet interfaces. With these high-performance ports, customers can connect Cisco Catalyst Cellular Gateways and get sub-6-GHz 5G wireless connectivity, reaching speeds of up to 3.3 Gbps and more with upcoming mmWave models. Get fast, flexible connectivity to the cloud that's able to be remotely activated and managed through the Catalyst SD-WAN Manager. Dual 5G SIM for failover and IP pass-through mean that multigigabit 5G for SD-WAN can either complement broadband internet connections or replace them entirely.

The Cisco Catalyst 8000 Edge Platforms Family provides customers the flexibility to increase memory, capacity, and performance. The portfolio offers investment protection with 5G technology. Cisco offers the highest-performing SD-WAN edge platforms in the industry, with end-to-end visibility through analytics for optimization of cloud applications and edge compute resources.

SD-WAN delivers rich benefits as far as costs, security, and simplicity. But the key to a successful SD-WAN transformation is to put the right focus on the initial setup and transition of the first 5 to 10 sites, then to expand SD-WAN across the rest of the enterprise rapidly. This is where services from Cisco Customer Experience are able to deliver the biggest value. Drawing from the best practices of successful deployments from numerous enterprises, ranging from simple to complex, the Cisco Customer Experience team's focus is to make the transformation smooth and avoid major hurdles. Categorizing the various sites, establishing templates, defining global policies, and enabling the right security architecture are a sure way to a smooth and successful deployment. An IDC study found that Catalyst SD-WAN customers on average achieved 38% reduced 5-year total costs of operations.⁸
