TL;DR: Identity attacks now concentrate in the browser, where stolen credentials, session tokens, OAuth consent abuse, and phished logins bypass legacy endpoint, email, and network controls, according to Push Security. The governing assumption has shifted: identity is the prize, and browser visibility is now a control plane, not a convenience layer.
Editorial analysis by NHI Mgmt Group, based on content published by Push Security: “How the browser became the main cyber battleground”.
Key questions
Q: What breaks when identity security is still built around email, endpoint and network controls?
A: Those controls miss the place where modern SaaS identity abuse happens: the browser.
Q: Why do browser-based phishing attacks increase account takeover risk so quickly?
A: They compress the gap between lure, credential capture, and session abuse.
Q: How do security teams know whether browser-layer identity detection is working?
A: Look for whether the programme can distinguish a normal page visit from a proxied login, a cloned form, a suspicious consent grant, or a token leaving the expected trust boundary.
Practitioner guidance
- Map browser-mediated login paths Inventory which SaaS applications rely on browser-based authentication, including SSO, backup methods, OAuth consent and app-specific passwords, so you can see where identity flows escape central control.
- Detect credential and session abuse in the browser Instrument the browser to capture login method, redirect chain, page behaviour, script activity and session handling so credential stuffing, AiTM phishing and session hijack can be identified in context.
- Reduce phishable fallback routes Remove or tightly constrain backup authentication methods, ghost logins and other downgrade paths that let attackers bypass stronger authentication when the primary login path is hardened.
Bottom line: Modern SaaS identity attacks now concentrate in the browser, where sessions, consent flows and passwords are easiest to misuse.

Browser identity telemetry is now a governance requirement, not a convenience feature. SaaS access has moved the decisive security boundary into the browser, where credentials, sessions and OAuth artifacts are created and used. Controls built around email gateways, network inspection and endpoint-only telemetry do not see the full identity transaction. The implication is that identity governance now needs runtime visibility into how access is actually exercised, not just how it was provisioned.
A question worth separating out:
A: If phishing and session theft are driving your identity risk, browser visibility deserves priority because that is where the attack is completed. Email controls still matter, but they are insufficient when the real compromise happens after the user reaches the login page or consent screen.
