What is a 
SWG (Secure Web Gateway)
?

SWG is a security checkpoint for your internet traffic.

SWG (Secure Web Gateway)
 Example

Think of it like: Airport security for your internet use, scanning your bags (web traffic), checking your ID (authentication), and stopping anything dangerous before you board (browse).

SWG sits between your users and the web, checking everything that goes in and out to keep threats out and sensitive data in.

What it does:

  • Blocks malicious websites (phishing, malware, etc.)
  • Filters content (e.g. blocks access to social media or adult sites at work)
  • Prevents data leaks (Data Loss Prevention)
  • Scans downloads for viruses or threats
  • Enforces compliance (so users follow company policy online)

Why it matters:

In a world where people work everywhere (not just in the office), an SWG:

  • Protects users wherever they are
  • Keeps your organisation safe from web-based attacks
  • Ensures consistent policy enforcement across all devices and locations

How it fits in with other tools:

  • VPN: Encrypts traffic and gives remote users access to the internal network
  • CASB (Cloud Access Security Broker): Monitors and secures access to SaaS apps
  • ZTNA (Zero Trust Network Access): Grants access based on identity and trust level, not just location
