What is a 

WSS (Web Security Service)

?

WSS (Web Security Service) also known as Secure Web Gateway (SWG)

What it does:

WSS is a cloud-delivered security service that:

• Monitors and filters internet traffic to and from users
• Blocks malicious websites or harmful content
• Enforces corporate browsing policies
• Often includes data loss prevention (DLP) and threat protection

Why it matters:

As employees work remotely or across multiple devices, WSS provides centralised, cloud-based protection without needing to backhaul traffic through a traditional on-prem firewall.

Example:

You're working from a café. Your laptop connects to the internet via a VPN to the company, but all your web traffic is filtered through a cloud-based WSS, it blocks dodgy websites, prevents malware downloads, and applies company browsing rules, even though you're not on the office network.
