What is Secure Web Gateway (SWG)?

Secure Web Gateway (SWG) is a cybersecurity solution that acts as a barrier between users and the internet, allowing organisations to enforce security policies and protect against web-based threats.

SWG Solutions Work By:

  • Filtering malicious websites and blocking access to harmful content

  • Scanning downloads for malware, ransomware, and other threats

  • Enforcing web usage policies to ensure compliance and productivity

  • Providing detailed reporting and analytics for complete visibility

  • Protecting remote workers with consistent security regardless of location


How Does Our Secure Web Gateway work?

Cloud Gateway's SWG security platform positions itself between your employees and the internet, creating a protective barrier that filters unsafe content and mitigates cyber threats before they reach your network.


Our SWG solution:

  • Verifies URLs against categorised threat databases updated hourly

  • Manages web application access with granular policy controls

  • Scans all downloads for malware and suspicious content

  • Decrypts SSL/TLS traffic to inspect encrypted communications

  • Blocks sensitive data exfiltration attempts

  • Logs all user activity for compliance reporting and monitoring

Secure Web Gateway features:

  • Uniform Resource Locator (URL) Filtering

  • Domain Name System (DNS) Inspection

  • Application Control

  • Proxy Services

  • Deep Packet Inspection (DPI)


Fact sheet

Uniform Resource Locator (URL) Filtering

URL filtering prevents end-users from accessing potentially harmful websites or resources that could be deemed non-work related. URL filtering can be specified by using major categories (gambling, adult, IT) or by reputation; these category databases are automatically updated every hour to ensure a robust filtering process, so you don't have to do this manually.

Deep Packet Inspection (DPI)

DPI allows SWG to apply controls based on information within the payload, which may not otherwise be seen due to encryption such as HTTPS/TLS in a web browser. DPI provides a more effective mechanism for executing network packet filtering. In addition to regular packet-sniffing technologies, DPI can find otherwise hidden threats within the data stream, such as attempts at data exfiltration, violations of content policies, malware, and more.

Domain Name System (DNS) Inspection

Domain Name System (DNS) is the mechanism to resolve a human-friendly name to a computer-friendly IP address. For example, 172.217.169.4 is commonly known as www.google.com. Amongst other capabilities, DNS filtering can filter DNS requests based on the domain category rating, or by your own domain categories. It also allows you to define and enforce domain and IP address lists to block or allow.

Application Control

With application control, you can identify and control which applications are trusted in the IT environment. An example may include “permit Zoom via the browser” but “deny the Zoom application”. You can also prevent unauthorised applications from running. These unauthorised applications may be from an unknown source, potentially malicious, or could simply be blocked to eliminate Shadow IT or duplication.

Proxy Services

Proxy Services act as a gatekeeper between your environment and the internet. An intermediary server separates users from the websites they browse rather than routing directly to the internet. This feature is usually combined with URL filtering and DNS Inspection services. For some organisations a “protocol break” is required between the user and the remote web location (server) for security compliance, an explicit proxy provides this.

Threat Intelligence Integration

We utilise a global threat intelligence subscription that categorises websites. SWG can be configured to combine both category and specific URL filtering.

You can block or allow websites that consume heavy bandwidth, contain mature content, carry a security risk or are simply unrelated to your business. The choice is yours!

Secure Web Gateways are important because they help to protect organisations from one of the industry's biggest cyber security threats, human error.

Cyber threats are increasingly sophisticated and can be concealed inside websites that may appear legitimate to the naked eye. When a user accesses a compromised website online, they may inadvertently divulge sensitive information or become exposed to malicious code - introducing risk to the wider organisation.

SWGs can inspect traffic, and be configured to block known malicious websites, helping to reduce the likelihood of a user causing a data breach or other security attack as a result of their online browsing.

Secure Web Gateways (SWGs) are essential for securing remote workers as they act as a separation point between globally distributed users and the internet.

With a remote workforce, organisations do not have direct control over devices and networks. By requiring remote workers to access the internet through SWG, companies with a hybrid or remote workforce can better prevent data breaches from a distance.

Both Secure Web Gateway and Web Application Firewalls enforce specific security policies, helping organisations protect themselves from cyber threats and data breaches, whilst complying with regulatory requirements.

However, their purposes are quite different. A Secure Web Gateway (SWG) is designed to eliminate unwanted software and internet traffic to ensure adherence to corporate and regulatory policies. A Web Application Firewall (WAF) is dedicated to safeguarding web applications from attacks through the filtration and monitoring of HTTP traffic.

A Virtual Private Network (VPN) primarily ensures secure inbound access and connectivity through encrypted tunnelling, while an SWG enables outbound internet access with comprehensive security inspection and filtering features.

Businesses are increasingly opting for cloud-based Secure Web Gateways (SWG) to enhance threat protection for an ever-expanding network estate. This cloud model eliminates the need for costly MPLS circuits which historically would backhaul traffic to a data centre for security policy to be applied.

By choosing a pure cloud-based SWG or a hybrid approach, companies can benefit from improved flexibility, simplified management, and enhanced performance.
