From Visibility to Action: Why Browser Telemetry Is Critical for Incident Response

From Visibility to Action: Why Browser Telemetry Is Critical for Incident Response

A few months ago, a security team at a mid-sized tech company got an alert: a user had accessed an internal tool and downloaded a sizeable report. Nothing flagged in the EDR. No malware detected. No failed logins. Just… a download. They shrugged. Seemed like a false alarm. A week later, customer data started surfacing online

The Clue They Missed? It Was in the Browser.

Turns out, the user had been phished. They’d visited what looked like a standard login page — but it wasn’t. Credentials were stolen, a session was hijacked, and an attacker quietly slipped in through the browser.

No malicious file. No obvious lateral movement. Just someone pretending to be an employee — inside a legitimate session.

The SOC team did everything right based on the data they had.
But they couldn’t see the browser. And that made all the difference.

The Modern Workspace Has Shifted

Today, work happens in tabs. Salesforce, Slack, Workday, Gmail — it’s all browser-based. Which means the browser isn’t just a productivity tool anymore. It’s a primary attack surface.

And yet, for most teams, it’s a blind spot.

  • You don’t see what URLs users visit.

  • You can’t track file uploads or downloads.

  • You don’t know when a shady extension is quietly exfiltrating data.

  • You can’t tell when someone’s session is hijacked from a phishing page.

And when incidents happen, you're left working backwards — without the full picture.

That’s why SURF was built

SURF’s Zero-Trust Enterprise Browser and Extension were designed to close this visibility gap.

They provide real-time browser telemetry — the kind that shows you:

  • What apps and sites your users are actually visiting

  • What data is being uploaded or downloaded

  • What extensions are running — and what permissions they have

  • How users are interacting with web apps, forms, and fields

  • Whether behavior aligns with policy — or flags as risky

This telemetry feeds directly into your existing security tools — so your SOC can see the full story, not just the headline.

 

No more Guesswork!

ith SURF, your incident response becomes faster and sharper.
You don’t need to guess if a download was legitimate — you know exactly where it came from and what triggered it.
You don’t have to assume a user was at fault — you can see if their session was hijacked or manipulated.

And in cases like the one above?
You’d have seen the phishing page.
You’d have spotted the session reuse.
You’d have acted days earlier — maybe before anything ever left the system.

The Browser Can’t Be Ignored

It’s where work happens.
It’s where attacks happen.
It’s time security happens there too.
