Secure Internet Access
Modern Internet Protection for Today's Workforce
SonicWall Secure Internet Access (SIA), part of the Cloud Secure Edge (CSE), delivers cloud-native security for internet-bound traffic, protecting your users and data from malicious websites, phishing, ransomware, and risky SaaS applications everywhere work happens.
Overview
Secure Internet Access: Protecting Users from Internet Threats
As organizations accelerate toward cloud‑native operations, the internet has effectively become the new corporate network. With it comes a new security mandate. Traditional perimeter defenses were never designed for a world where employees connect from anywhere, data flows across countless SaaS applications, and threats hide behind encrypted traffic and everyday browsing. Businesses now need protection that is both proactive and frictionless, securing users without slowing them down.
SonicWall Secure Internet Access delivers exactly that. With integrated Secure Web Gateway (SWG), risk-based URL filtering, and Cloud Access Security Broker (CASB), Secure Internet Access ensures safe access to the open internet without slowing productivity. Secure Internet Access filters harmful content at the DNS and web layers to block threats before they reach users, enforces acceptable use policies, and stops risky behavior.
Getting Started with CSE
What SIA Solves
Web-Based Threats Target Every User
Phishing, ransomware, malicious ads, and compromised websites can infect users from any browser or device. Secure Internet Access blocks malicious domains, URLs, and files using real-time threat intelligence, DNS filtering, and advanced content inspection, preventing threats from reaching your users.
Legacy Web Security Can’t Keep Up With Modern Workflows
Organizations still relying on legacy on‑prem appliances face blind spots, capacity limits, and outdated security that leave users exposed. Secure Internet Access comes with cloud‑delivered inspection and policy enforcement, ensuring every connection to the internet is scanned and updated with the latest protections.
Hybrid & Remote Users Break Traditional Security Models
Employees work from unsecured networks and unmanaged devices, bypassing perimeter controls and increasing exposure. Secure Internet Access enforces identity, device, and context-aware security policies for all users, ensuring consistent protection for both remote and on-site traffic.

How SIA Works
Secure Internet Access delivers safe, consistent access to online resources through identity-aware, policy-driven controls reinforced by device posture and real-time threat evaluation.
Secure Web Gateway (SWG)
Protects users from malicious, risky, or inappropriate websites through advanced URL filtering, real-time threat prevention, granular policy enforcement, and deep content inspection. This ensures safe, compliant browsing across all users and devices.
DNS-Layer Security & Risk-Based URL Filtering
Delivers layered protection by blocking malicious domains instantly at the DNS layer and applying deeper, risk-based URL inspection, including encrypted traffic and page-level controls, for real-time, context-aware threat prevention.
Cloud Access Security Broker (CASB)
Secure Internet Access incorporates CASB capabilities that profile all SaaS traffic, classify application risk, and enforce adaptive, context-aware controls. With real-time inspection and policy enforcement, CASB identifies shadow IT, restricts unsanctioned app usage, and applies data protection policies to prevent leakage or unauthorized sharing across cloud services.
Cloud-Delivered Architecture
All traffic is intelligently routed to the nearest global cloud Point of Presence (PoP), providing low latency and high performance while applying consistent, always‑on security controls, no matter where users connect from.
