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

Why It Matters

Without visibility into browser interactions, organizations cannot detect or explain sophisticated attacks that bypass existing defenses, exposing sensitive data and undermining security investments, especially as AI‑enhanced browser use accelerates the risk.

Summary

Keep Aware warns that enterprise security tools—EDR, email gateways, and SASE—systematically miss a growing class of browser‑only attacks, including click‑fix UI social engineering, malicious extensions, man‑in‑the‑browser manipulations, and HTML smuggling. These techniques leave little forensic evidence because they exploit user interactions inside the browser, a layer not monitored by traditional controls. The firm’s research across more than 20 browsers shows widespread policy deployment but a lack of observable behavior, a gap that AI‑driven workflows and AI‑native browsers are widening. Gaining real‑time browser‑level visibility would enable detection, response, and policy refinement, closing the “safe haven” attackers now exploit.
