Most organizations have already strengthened authentication with passwords, passkeys, and multi-factor authentication. Those controls are essential, but they all verify identity at a single moment: when someone signs in.
Once a browser session is authenticated, how do you know the same person is still using it an hour later?
For Google Workspace administrators managing hybrid and remote teams, that’s becoming one of the biggest identity gaps to address.
Here’s what continuous verification actually looks like in practice.
Why Hybrid Work Changes the Identity Problem
In an office, a device left unlocked gets noticed. Someone walks past, a colleague locks it for you, IT does a walk-through. None of that exists at home, in a co-working space, or on a train.
Hybrid and remote employees work across more networks, more physical locations, and often more devices than an office-based team ever did. A laptop stays logged into Gmail and Drive for an entire workday without anyone else present to notice if it’s left open. This visibility gap often leads to unmonitored Shadow IT in Google Workspace, where users install unvetted extensions or connect risky OAuth applications while outside the corporate perimeter.
Field and shift-based staff frequently share devices where the previous session isn’t always closed properly before the next person starts. None of this is unusual behavior. It’s just what happens when work isn’t confined to one supervised location.
This is precisely the environment Zero Trust was built to address, and precisely the environment where most identity checks still only run once, at login.
Where the Trust Actually Sits
A password, an MFA prompt, a passkey. Each of these verifies identity once, at the moment someone signs in. From that point forward, the session is trusted by default. Nothing checks again whether the person still using it is the person who logged in.
For most Google Workspace domains, that’s the entire identity model: strong at the door, unmonitored after that. It works fine until the session outlives the person it was issued to:
- – A laptop left open at a home desk with family nearby.
- – A device handed off between shift workers without a proper logout.
- – A session cookie lifted via an infostealer from a compromised machine.
None of these scenarios triggers a new login event, so MFA never runs again. Admin console logs show a legitimate, authenticated user in every case, because technically, that’s exactly what they’re logged as. This is the gap Zero Trust actually describes, even if the term gets used more loosely elsewhere. Verification that happens once isn’t verification that holds for an entire workday, especially one that moves across locations and devices the way hybrid work does.
Why This Is a Google Workspace Problem Specifically
Nearly everything a Workspace domain protects, Drive files, Gmail, Calendar, and shared documents, is accessed through the browser. That makes the browser the actual point of exposure, not the network. You can restrict VPN access and enforce device policies and still have this gap open, because it isn’t a network issue. It’s a question of how long a session stays trusted once it’s opened, and whether anything is checking during that time, wherever the employee happens to be working from that day.
It also reframes how insider risk should be evaluated. Most unauthorized access isn’t a planned, malicious act of sabotage. It’s opportunistic: someone using a session that was never properly closed, on a device that was never designed to be monitored once it left the office. That’s a meaningfully different problem to plan for than the “rogue employee” scenario most insider threat guidance defaults to.
What Continuous Verification Looks Like in Practice
Adding a second MFA prompt partway through a session isn’t a real answer. It adds friction for every legitimate remote worker, and it doesn’t stop someone who has already bypassed the first check, or isn’t the one being prompted in a shared device scenario.
The alternative is verification that runs silently in the background without interrupting anyone.
How ActiveID Delivers Continuous Behavioral Authentication
The alternative is verification that runs in the background without interrupting anyone. GAT’s ActiveID does this using typing behavior: every person has a measurably consistent typing rhythm, including how long keys are held and the pause between specific key pairs. ActiveID builds a model of this per user and checks it continuously while they work, regardless of which network or location they’re connecting from, not just once at login. It’s part of GAT Shield+, which extends GAT Shield’s browser visibility with this continuous identity layer.
If the typing pattern stops matching the logged-in user, the response follows whatever policy the domain has set. That can mean an alert to the security team, a reauthentication prompt to the active user, evidence captured for review, or the session ending outright. None of this replaces MFA or passkeys. It covers the part of the session neither of them was built to monitor, which matters more, not less, once your team isn’t all working from the same building.
What to Check on Your Own Domain
- A few questions are worth answering honestly, independent of any specific tool:
- How many active sessions currently exist on shared or field devices across your organization?
- If a session cookie were stolen from a remote employee’s device today, would anything in your current stack flag the reuse?
- Does your idle session policy get enforced automatically, or does it depend on someone remembering to log out, wherever they happen to be working that day?
If you’re not confident in the answers, that’s worth auditing before it becomes an incident. Maintaining continuous verification is no longer optional for organizations aiming to meet strict SOC 2 and ISO 27001 compliance standards in Google Workspace. GAT+ gives you visibility into what’s happening across Drive, Gmail, and Groups on your domain, no matter where your users are working from.

Frequently Asked Questions
1. What is continuous identity verification?
Continuous identity verification validates that the authenticated user remains the active user throughout a browser session, rather than only during login.
2. Does Google Workspace verify users after login?
Google Workspace provides strong authentication through passwords, passkeys, and multi-factor authentication. However, continuous verification after login requires additional browser security controls.
3. Why are browser sessions a security risk?
Browser sessions can remain authenticated for hours. Unattended devices, shared workstations, and compromised sessions may allow unauthorized access without triggering a new login or MFA challenge.
4. How can Google Admins better protect browser sessions?
A layered approach includes continuous identity verification, browser monitoring, anti-phishing protection, copy and paste controls, real-time alerts, audit logs, and SIEM integration to improve visibility and reduce browser-based risk.
