Security Service Edge (SSE), Securing Access to the Internet in the Modern Era

In this blog post, we will delve into the concept of Security Service Edges (SSE) and explore why they have become essential in the era of cloud computing and user mobility. SSE enables businesses to secure access between authorized users and specific applications, whether they are hosted in the cloud, legacy data centers, SaaS platforms like Microsoft 365 and Salesforce, or even the open internet. We will discuss the challenges organizations face in network security due to the lack of control over cloud networks and personal Wi-Fi connections. Moreover, we will explore how SSE addresses these challenges and allows the internet to function as the new corporate network. Let’s dive into the world of Security Service Edges and understand their significance in modern cybersecurity.

The Need for Secure Connectivity in the Cloud Era

The rise of cloud computing and user mobility has necessitated the development of Security Service Edges (SSE). Learn why secure connectivity is crucial in today’s digital landscape.

The increase in cloud and user mobility has transformed the way businesses operate. However, without a secure means of providing connectivity, leveraging the cloud becomes ineffective. Discover how SSE plays a vital role in securing access to authorized users and their applications.

Network Security in an Uncontrolled Environment

Unlike traditional network security, organizations can no longer control the networks their applications rely on, such as Microsoft 365, AWS, or Azure. Explore the challenges of network security in an environment where cloud and personal networks are beyond organizational control.

As organizations embrace cloud services and remote work, securing access to the internet poses a significant challenge. We will delve into the implications of relinquishing control over network infrastructure and how SSE provides a solution in this rapidly changing landscape.

From Secure Web Gateways to Zero Trust Network Access: The Evolution of SSE

Discover the evolution of security technologies that led to the emergence of Secure Access Service Edge (SASE) and the integral role played by SSE within the framework.

Over the years, various security technologies such as secure web gateways, cloud access security brokers, and zero trust network access have evolved. We will explore how these technologies converged to form the SASE framework, with SSE being a crucial component. Gain insights into the journey from disparate security solutions to an integrated set of services in the cloud.

Understanding the SSE Architecture

Uncover the high-level architecture of SSE and its fundamental differences from traditional network security. Learn how SSE focuses on securing individual connections to specific applications rather than network-wide connectivity.

The architecture of SSE differs significantly from traditional network security. We will examine the key elements and flow of traffic within SSE, emphasizing the termination point, authentication, authorization, and application-specific connections. By understanding these architectural differences, you’ll gain a clearer perspective on how SSE enhances security and access control.

Benefits of SSE: Security, User Experience, and Simplified Management

Explore the benefits SSE brings to businesses, including enhanced security, improved user experience, and simplified policy management.

Implementing SSE offers multiple advantages beyond security. We will delve into how SSE enables in-line inspection, application-level segmentation, and digital experience monitoring. Additionally, discover how SSE minimizes cost and complexity by eliminating the need for physical appliances and network segmentation. Learn how SSE streamlines policy management and enhances user experience.


In conclusion, Security Service Edges (SSE) play a vital role in securing access to applications in today’s cloud-based and mobile environment. By embracing SSE, businesses can leverage the internet as the new corporate network while ensuring robust security measures are in place. We explored the challenges posed by the lack of control over networks and the evolution of security technologies leading to the emergence of SSE within the SASE framework. Understanding the SSE architecture and its distinct differences from traditional network security is essential to grasp its benefits fully. SSE offers improved security, enhanced user experience, and simplified policy management, revolutionizing the way organizations connect and protect their resources in the modern era.
