What is Cisco's Approach to SD-WAN?

Cisco's SD-WAN offering is designed with multicloud capabilities in mind to ensure secure connectivity and an enhanced experience for both on-premises and cloud-hosted applications.

The Cisco Catalyst SD-WAN introduces a high degree of control over IT infrastructure. Through built-in automation and detailed analytics, the Cisco solution provides IT teams with the power to manage networks with precision across a range of connection types.

By leveraging components of Catalyst SD-WAN, businesses can converge network and security functions with a focus on identity and policy enforcement.

Benefits and Challenges of Cisco's SD-WAN

Cisco SD-WAN is designed to address the challenges of WAN management by providing a better application experience and promoting security at branch locations.

Cisco benefits typically demonstrate a lift in application performance, a more resilient network, and an improved user experience. Network monitoring and traffic steering move beyond conventional WAN capabilities to ensure better access to cloud platforms and corporate data centres.

However, transitioning from legacy WAN infrastructure presents its own set of problems. The complexities of merging Cisco SD-WAN with existing IT frameworks and scaling the network to meet future needs could pose challenges to organisations. Cisco counters these difficulties as a component of their SD-WAN solutions by providing visibility and featuring integrated security measures, these include zero-trust enforcement and secure segmentation.

Cisco's SASE (Secure Access Service Edge)

Cisco's SASE model represents a convergence of networking and security services directly from the cloud, which aims to offer integrated solutions that adapt to the changing demands of Enterprise businesses. By combining security features with SD-WAN technology, Cisco provides a framework to secure and streamline the connectivity of organisations.

Cisco's SASE Solutions

Cisco has engineered a SASE architecture that merges VPN and SD-WAN functionality with a range of cloud-native security features. These features include secure web gateways, cloud access security brokers, firewalls, and zero-trust network access (delivered as a comprehensive service from the cloud).

At the core of Cisco's SASE solutions is the coordination between SD-WAN, which optimises performance and cost by directing traffic across leased lines, broadband and cellular, and cloud security components. Cisco Cloud works to monitor and protect data and applications regardless of where the user is located.

The inclusion of zero-trust network access means that no entity is trusted by default, whether inside or outside of the network perimeter. SASE solutions are incorporated by Cisco Umbrella, which has been designed as an 'umbrella' to bring together the complete Cisco cybersecurity portfolio.

Why Cisco SASE makes sense for larger Enterprise solutions

For larger enterprises, Cisco SASE emerges as a good-fit solution due to its capacity to meet complex needs via centralised management and real-time application optimisation.

Cisco’s focus on providing reliable connectivity and high availability ensures that all users are able to securely access data centre resources and cloud services including SaaS applications such as Salesforce, infrastructure-as-a-service (IaaS) platforms, and critical applications hosted on Microsoft Azure.

Cisco's SASE solutions address the challenges larger enterprises encounter with network security and access. These challenges include maintaining consistent policy enforcement across devices, while adapting to the bandwidth demands and diverse user requirements.

The scalable nature of Cisco's SASE framework means it can keep pace with enterprise growth, reducing operational expenditure (OPEX) and minimising the need for troubleshooting. This integrated approach aligns with the enterprise security networks of tomorrow.

Cisco's SSE (Security Service Edge)
