TL;DR: Identity theft, credential abuse, and session hijacking inside the browser now drive the breaches that matter most, according to Push Security and cited threat intelligence from Verizon, CrowdStrike, Mandiant, Palo Alto Networks, and Omdia. Browser hardening still has value, but it does not address the dominant attack path.

Editorial analysis by NHI Mgmt Group, based on content published by Push Security: “How to avoid the browser security buyer's trap”.

Key questions

Q: What fails when browser security only looks for exploit prevention?

A: Exploit-only browser security misses the dominant enterprise threat path, which is identity abuse through legitimate login flows.

Q: Why do browser-based identity attacks create more risk than browser exploitation in many enterprises?

A: Because attackers can use legitimate login flows to inherit valid access, which is cheaper and more reliable than developing browser zero-days.

Q: What do security teams get wrong about browser security investments?

A: They often buy controls that defend the browser software, then expect those controls to stop identity theft inside the browser session.

Practitioner guidance

  • Reclassify browser risk as identity risk Map phishing, AiTM, token theft, and OAuth consent abuse into your IAM and NHI threat model instead of keeping them in a browser-only control bucket.
  • Measure session-level exposure Inventory where valid browser sessions, tokens, and delegated grants can be replayed or hijacked across managed and unmanaged devices.
  • Prioritise identity-aware browser telemetry Use controls that can detect credential entry on cloned pages, anomalous session context, and malicious consent grants while authentication is happening.

Bottom line: The main browser risk today is identity abuse inside normal sessions, not browser exploitation itself.

Browser security is now an identity governance problem in disguise. The decisive risk is no longer whether the browser can be exploited, but whether the browser is the place where identity state is stolen, replayed, and abused. That shifts the centre of gravity from endpoint hardening to identity assurance at session time. Practitioners should treat browser telemetry as part of IAM, not as a separate browser-only control plane.

A question worth separating out:

Q: How should teams judge whether browser controls are aligned to identity risk?

A: They should ask whether a control can see and stop credential theft, token replay, and OAuth abuse inside real sessions, including on unmanaged devices. If the answer depends on malware detection, sandboxing, or exploit telemetry alone, the control is misaligned. Good coverage follows the authentication event and the session, not just the endpoint.
