Interactive · Browser Security

The browser is your real endpoint. Secure it like one.

Your team lives in tabs. So do modern attacks: lookalike login pages, stolen session cookies, over-permissioned extensions, and uploads into tools you never approved. We put controls inside the browser your staff already use, with no migration and no proxy detour.

The gap

Your stack watches the device and the inbox. Attackers moved to the tab.

Email filtering, EDR, and firewalls all do their job. None of them sit where the credential is typed, the extension reads the page, or the file is dragged into a web upload box.

[ without browser controls ]

Blind inside the tab

  • Phishing links arriving via chat, SMS, and ads bypass email filters
  • Lookalike login pages harvest credentials in seconds
  • Stolen session cookies replay past MFA entirely
  • Any extension can read every page a user opens
  • Files uploaded to personal storage and public AI unlogged
  • Contractor browsers reach your SaaS with zero posture check

Policy at the point of the click

  • Malicious and impersonation pages blocked as they render
  • Corporate credentials refused on unapproved domains
  • Session tokens protected and risky sessions terminated
  • Extensions allowlisted by role and audited monthly
  • Uploads, downloads, and paste governed by data sensitivity
  • Unmanaged and BYOD devices covered without full enrollment
Capabilities

What we actually enforce in the browser

Six controls, one policy engine, deployed to the browsers your staff already have open.

Phishing and lookalike blocking

Malicious and impersonation pages are identified as they render, not just by domain reputation. Newly registered lookalike login pages are stopped before credentials are typed.

NIST SI-3CIS 9.3HIPAA §164.308(a)(5)

Extension governance

Full inventory of every installed extension and its permissions. Allowlist by role, block read-all-site-data extensions, and remove risky ones fleet-wide in minutes.

NIST CM-7CIS 4.8CMMC CM.L2-3.4.8

Credential and session protection

Corporate passwords cannot be reused on unapproved sites. Session tokens are protected against theft and replay, and suspicious sessions can be terminated in real time.

NIST IA-5CIS 6.5PCI DSS 8.3

Upload, download, and paste control

Policy decides what can leave through the browser. Block uploads of sensitive files to personal storage and unsanctioned AI, and scan or block risky downloads.

NIST SC-7CIS 3.3HIPAA §164.312(e)

Web app and SaaS visibility

A named inventory of every web app your staff touch, with usage by user. The fastest route to finding shadow SaaS and unsanctioned AI already in the business.

NIST CM-8CIS 2.1SOC 2 CC6.1

Contractor and BYOD coverage

Protect unmanaged devices at the browser layer so third parties reach your SaaS under policy without you having to own or enroll their hardware.

Anatomy of a browser attack

Four steps from a single click to a drained account

This is the sequence we see most often in mid-market incident work. Browser controls break it at step two, before anything is typed.

01 · The lure

A link arrives through chat, SMS, a search ad, or a shared document. Nothing touches the mail filter.

02 · The clone

A pixel-perfect login page on a domain registered hours ago. Reputation feeds have not caught up yet.

03 · The handover

Credentials and the MFA prompt are relayed live to the attacker, who captures the session cookie.

04 · The takeover

The session is replayed from elsewhere. Mail rules, payroll changes, and data exports follow.

Browser-level detection evaluates the page as it renders, so a clone registered an hour ago is blocked on its first victim rather than its hundredth. Credential reuse controls mean that even a missed page cannot collect a working corporate password.

How it works

Monitor, tune, enforce, operate

No big-bang rollout. We measure real usage first so enforcement lands without a wave of helpdesk tickets.

01

Baseline

Deploy in monitor mode across your fleet. Inventory browsers, extensions, web apps, and risky behaviors without blocking anything yet.

02

Tune

Classify what is business-critical, what needs a sanctioned replacement, and what gets blocked. Build role-based extension and upload policy against real usage.

03

Enforce

Turn on phishing and credential protection, extension allowlisting, and data-movement controls with a fast exception workflow your helpdesk owns.

04

Operate

Ongoing monitoring, monthly reporting on blocked attacks and policy exceptions, and continuous tuning as your SaaS estate changes.
