What is Security Service Edge (SSE)?

Security Service Edge (SSE) is a cloud-based security framework that protects users, devices, and data across environments. SSE delivers security services directly from the cloud, enabling organizations to secure digital assets without relying solely on traditional perimeter-based defenses.

How Does SSE Work?

SSE works to protect data, detect threats, and control environment access. It integrates with existing security and cloud services, using cloud-native technologies to offer real-time visibility and control over user activities and data flows.

• Data Protection: SSE employs advanced security mechanisms like encryption, data loss prevention (DLP), and secure access controls to safeguard sensitive information both in transit and at rest.
• Threat Detection: SSE enables rapid response to incidents through use of real-time threat detection, powered by machine learning and artificial intelligence (AI), to identify anomalies and potential threats.
• Access Control: SSE enforces granular access controls based on user identity, device posture, and contextual factors, using a zero trust approach to minimize the attack surface.

The cloud-native technologies that SSE uses allow for scalability, provide consistent protection across various environments, and offer the flexibility to adapt.

Why Is Security Service Edge (SSE) Important?

As employees and data are increasingly located outside the office, SSE helps consolidate and streamline security functions into a single, globally-available cloud-based solution. Some of the major security challenges that SSE addresses include:

• Dissolving Perimeters: Historically, security models were perimeter-focused. These models were based on the assumption that corporate resources were deployed in the corporate datacenter and that securing the connection between the corporate network and the public Internet secured the enterprise. As the traditional perimeter dissolves with the adoption of cloud infrastructure, SaaS, remote work, mobile devices, and the Internet of Things (IoT), traditional centralized security models no longer work. SSE enables companies to deploy security closer to where the user and data is located, with inspection engines delivered from a global network of cloud points of presence (PoPs).
• Security Complexity: As IT infrastructures grow more complex and companies face an evolving threat landscape, many organizations have deployed an array of standalone security solutions to address various threats. As a result, security architectures are hard to monitor and manage, making it easier for cyberattacks to slip through the cracks. SSE consolidates security functionality into a single, integrated solution managed with unified policies, where data is decrypted, inspected and decrypted in a single cloud-delivered security stack, reducing the need for a complex array of standalone security tools.
• Network Performance: Attempting to secure distributed infrastructure with perimeter-based solutions results in inefficient network routing, latency and a poor user experience, where all traffic is backhauled to a central physical location for the purpose of security inspection by an enterprise security stack. SSE eliminates the need for these inefficient routes by deploying security near the users and resources that need it, allowing traffic to be more efficiently routed to its destination.
• Operational Efficiency: Security Service Edge consolidates security functionality into a single, integrated, and cloud-based solution. This makes it easier for security teams to deploy, configure, monitor, and manage security solutions, improving efficiency and reducing operational overhead. Day-to-day operations such as creating backups and ensuring high availability and redundancy are offloaded to a cloud security vendor.

What Are The Main Components Of Security Service Edge?

Security Service Edge is designed to converge network security into a single, cloud-based solution. The primary components of SSE include:

• Zero-Trust Network Access (ZTNA) : ZTNA provides a superior alternative to virtual private networks (VPNs) for secure remote access to corporate resources. ZTNA enables organizations to implement granular, in-app zero trust security for remote access to corporate applications residing on on-premises or in the cloud (e.g. internal web apps, wikis, databases, remote desktops and servers, SSH terminals and cloud production environments).
• Secure Web Gateway (SWG) : SWGs are designed to protect employees from internet and web-based threats, including phishing sites, malware and ransomware infection points and command and control (C2) bot clients. An SWG monitors and filters web traffic to enforce corporate security policies, block access to known-bad sites, and block malicious files from reaching the user’s system. Key capabilities of an SWG are access control, data protection and threat prevention.
• Firewall as a Service (FWaaS) : A firewall is the cornerstone of a corporate network security policy, enabling an organization to restrict network access and block malicious files from entering the network. FWaaS offerings provide firewall functionality under a service-based model, offering greater flexibility and scalability than appliance-based solutions. In the context of SSE, FWaaS refers to securing branch offices, data centers and remote sites using cloud-based network security. FWaaS integrates with SD-WAN solutions to enforce consistent security across numerous sites and branch offices in an automated fashion.
• Cloud Access Security Broker (CASB) : As companies become more dependent on a range of Software as a Service (SaaS) applications, they need solutions that enforce corporate security policies and access controls across cloud services. CASB solutions help manage access and protect data accessed in SaaS applications, with capabilities that include authentication, single sign-on, authorization, encryption, monitoring and threat prevention, among others.
• Identity and Access Management (IAM): IAM governs user identities and access to resources, enabling organizations to manage user identities, enforce authentication protocols, and implement role-based access controls.
• Data Loss Prevention: DLP mechanisms protect sensitive information from unauthorized access and exfiltration, monitoring data in motion, at rest, and in use, and applying policies to prevent data leaks.
