A Secure Web Gateway (SWG) is a cybersecurity solution that acts as a checkpoint between users and the internet, filtering traffic to ensure safe, policy-compliant access. It blocks harmful websites, enforces organizational rules, and prevents data leaks—all in real time.
To put it simply: a Secure Web Gateway monitors every web request made by users and ensures that the request—and its response—doesn’t violate any security policies. It blocks malware, phishing links, and risky websites before they ever reach the user.
Whether someone is trying to open a web page, access a cloud app, or download a file, the SWG checks the request for safety. If it meets policy rules, it’s allowed. If not, it’s stopped immediately.
What makes SWGs powerful is their deep traffic inspection—especially encrypted HTTPS traffic. They decrypt, inspect, and re-encrypt traffic to spot hidden threats that traditional tools might miss. They can also:
- Apply user identity-based access controls
- Restrict access by user role or device type
- Enforce acceptable use policies
- Prevent unauthorized data uploads or downloads
Secure Web Gateways work alongside other security technologies like gateway firewalls, endpoint protection, and cloud access brokers. Platforms like Fidelis Network® enhance SWG capabilities by providing deep session inspection, behavioral analytics, and threat intelligence integration—strengthening overall visibility and control.
SWGs aren’t just about security—they’re about control, visibility, and compliance in an increasingly complex web environment. As remote work and cloud adoption grow, SWGs are becoming essential for protecting users and data everywhere.
