Secure Web Gateway
That Blocks Threats
Before They Land

A Secure Web Gateway (SWG) is a cloud-delivered network security solution that filters all internet-bound HTTP/HTTPS traffic to protect enterprise users from web-based threats — malware, phishing, ransomware, and data exfiltration. Unlike a traditional next-generation firewall that primarily controls inbound traffic at the network perimeter, an SWG focuses on outbound web traffic with deep SSL/TLS inspection, URL categorisation, and user identity-awareness baked in. Modern cloud SWG is SASE-compatible and protects users wherever they work, with no hardware or VPN infrastructure required.

NetNXT SWG uses AI-driven threat intelligence and real-time URL reputation scoring to block access to malicious websites before any connection is established. For encrypted HTTPS traffic, our SSL/TLS inspection engine decrypts, inspects, and re-encrypts web sessions to detect hidden malware payloads and phishing pages. An inline sandbox detonates suspicious file downloads using behavioural analysis — stopping ransomware and zero-day threats at the secure internet gateway before they reach user endpoints.

Yes — this is one of the primary advantages of cloud-delivered SWG over on-premises web proxies. NetNXT SWG extends identical corporate security policies to every user regardless of location: office, home, or travelling. A lightweight agent or agentless browser proxy routes internet-bound traffic through our globally distributed PoPs, ensuring consistent policy enforcement and sub-10ms latency without slow VPN backhauling. Remote workers receive the same web gateway protection as on-premises users with no additional configuration required.

NetNXT SWG acts as a trusted intermediary: it decrypts outbound HTTPS sessions, inspects the payload against threat signatures and data loss prevention (DLP) policies, then re-encrypts and forwards clean traffic. To protect user privacy and maintain regulatory compliance, administrators define bypass lists that exclude sensitive categories — online banking, personal health portals, government services — from decryption entirely. All inspection policies are logged and auditable, providing a clear chain of custody for compliance teams.

A Secure Web Gateway (SWG) secures general internet-bound web traffic from users to any website or cloud service. A Cloud Access Security Broker (CASB) governs access to specific sanctioned SaaS applications — Microsoft 365, Salesforce, Box — and enforces data policies within those apps. SASE (Secure Access Service Edge) is a Gartner-defined architecture that converges SWG, CASB, Zero Trust Network Access (ZTNA), SD-WAN, and Firewall-as-a-Service (FWaaS) into a unified cloud-delivered service. NetNXT's SWG is SASE-ready and integrates natively with our CASB and Zero Trust services.

NetNXT SWG adds an average of less than 10 milliseconds of latency per request — genuinely imperceptible to end users. This is achieved through a globally distributed cloud architecture with regional PoPs located close to users, eliminating the backhauling overhead of on-premises proxies and VPN concentrators. Cacheable content is served locally and our inspection pipeline is optimised for enterprise-scale throughput. Many organisations report improved perceived web performance after deployment because we remove bandwidth-heavy shadow IT and streaming traffic.

Yes. NetNXT SWG produces comprehensive, tamper-proof logs of all web activity that support compliance with GDPR, HIPAA, PCI DSS, ISO 27001, and SOC 2 requirements. Built-in data loss prevention (DLP) policies prevent sensitive data — PII, PHI, card data — from leaving the organisation via web uploads or form submissions. Automated reporting dashboards simplify audit evidence collection and push structured logs directly to your SIEM for correlation and long-term retention.
