What Security Leaders Should Expect from a Modern SWG

The Secure Web Gateway was already the wrong tool for stopping attacks. AI-enabled adversaries made that impossible to ignore.

SWGs were built to enforce acceptable use — block unapproved sites, log activity, keep employees inside the lines. They were never built to stop threats delivered inside traffic the gateway is designed to allow. And documented vulnerabilities are on pace to reach one million by 2030, roughly 300% more than in 2025.

RBI, IOC feeds, and sandboxing were layered on to close the gap. They added latency, alerts, and cost. The gap stayed open. Many vendors now position a full SSE/SASE transformation as the answer. Not every organization needs one.

This eBook is for security leaders replacing an SWG who want to evaluate it on the criterion other gateways ignore: whether it actually stops attacks.

What’s Inside:

• Where legacy SWGs fall short — and why RBI, IOC feeds, and sandboxing never sealed the gap
• What the failure costs: HTML smuggling, trusted-cloud abuse, and threats the gateway logs but can't stop
• What a modern SWG should deliver — full-session inspection, TTP-based detection, real-time threat removal — plus a vendor-neutral checklist for evaluating any replacement

The gateway has had two decades to become a security control. It stayed a policy tool, and the patches bolted onto it never changed that. The only way to stop threats at the gateway is to inspect the full session and remove the threat before it reaches the user.
