EDR, Email, and SASE Miss This Entire Class of Browser Attacks

This sponsored Keep Aware report explains how modern browser-based attacks — including click-driven social engineering, malicious extensions, man-in-the-browser activity, and HTML smuggling — evade traditional defenses (EDR, email security, SASE) by operating inside the browser where visibility is limited. It presents research across browsers, warns that AI-native tools amplify data movement risk, and advocates for browser-level observability to enable precise prevention, better detection, and reconstructable incident response.
