Browser Security One Platform

Discover, detect, and protect every browser extension in your fleet

Extension Auditor’s companion agent inventories installed extensions, evaluates risk, pushes policies, and helps your team investigate and stop malicious browser extensions before they spread.

Discover

Continuous inventory across Chrome, Edge, and Brave — know what is installed, where, and by whom.

Detect & protect

Score risk, push allow / warn / block policies, and stop malicious extensions from landing on managed browsers.

Investigate

Trace blast radius across the fleet when an extension turns bad after a malicious update.

Built for how security teams actually work

Three core capabilities that take you from unknown browser risk to enforced policy and investigation — without the work scattering across store pages and spreadsheets.

Platform · Discover

See every extension in the fleet

Inventory installed extensions across managed browsers so nothing runs outside your visibility.

Learn more Platform · Protect

Push policy, not hope

Allow, warn, or block at the browser with companion-agent enforcement when risk crosses the line.

Learn more Platform · Investigate

Contain without the chaos

Map blast radius, revoke exposure, and tighten policy when an extension flips malicious after an update.

Built around how security teams work

Opinionated on browser extension risk, flexible on how you enroll, alert, and enforce — so SecOps stays in flow.

FIG 0.1

Built for browser risk

Purpose-built for extension inventory, risk scoring, and policy — not a generic endpoint bolt-on.

FIG 0.2

Companion-agent coverage

Enroll Chrome, Edge, and Brave profiles so installs and updates report into one fleet view.

FIG 0.3

Faster time to control

Go from unknown surface area to warn/block policies without months of store-page reviews.

One platform for the full browser extension lifecycle

From first inventory to policy enforcement and incident response — without stitching together spreadsheets and store pages.

Discover your extension surface

Enroll browsers with the companion agent and get a live inventory of installed extensions, versions, publishers, and permissions across your organization.

Explore Identify

Detect risky and malicious extensions

Combine permission analysis, publisher reputation, and ML risk signals to surface critical and high-risk extensions as soon as they appear or update.

Explore Detect

Protect with policy enforcement

Push report-only, warn, or enforce policies so malicious and unapproved extensions are blocked at the browser — not after the fact.

Explore Protect

Investigate and prevent recurrence

When something slips through or flips malicious post-update, map exposure across agents, contain quickly, and tighten policy so it does not return.

Platform capabilities

What you get under Browser Security One Platform

Purpose-built for security teams who need fleet visibility and control — not just a one-off store lookup.

Fleet inventory

See every managed browser’s extensions in one place, with risk context tied to each install.

Continuous monitoring

Catch malicious updates, permission changes, and new installs without manual store reviews.

Policy push

Enforce allow / warn / block verdicts through the companion agent across Chrome, Edge, and Brave.

Investigation workflows

Understand who is affected, how far an extension spread, and what to revoke next.

Shaped around how security teams operate

Three foundations that take browser extension risk from unknown surface area to enforced policy — without the work scattering across tools.

Inventory with purpose

Map every managed browser’s extensions into one fleet view before you write a single policy.

Decide with evidence

Score risk from permissions, publishers, and ML signals so allow / warn / block calls are grounded.

Enforce without drama

Push policies through the companion agent and keep releases moving toward a safer fleet.

Govern the fleet and bring security along

Organize extension risk into clear lanes, then channel enforcement into one flow your team can run.

Shape risk into policy lanes

Separate allow, warn, and block so priorities stay obvious across the fleet.

Channel findings into action

Guide installs and updates into one investigation flow so responders keep momentum.

Fits the stack your security team already runs

Route alerts to Slack, Teams, webhooks, and SIEM-friendly destinations so browser extension risk shows up where your responders already work.

Extension Auditor Support

Typically replies during business hours

Do we need to deploy an agent on every browser?

Yes for fleet inventory and policy enforcement. The companion agent enrolls Chrome, Edge, and Brave profiles against your team workspace and reports installed extensions.

2:41 PM

Can we start in report-only before blocking?

Yes. Run report-only or warn first, review risk in the inventory, then flip to enforce when you are ready to auto-block malicious extensions.

2:43 PM

How is this different from the Threat Intel API?

The platform discovers, detects, protects, and investigates across managed browsers. The API is key-based lookups that return JSON — no agent or fleet required.

Secure the browser layer your EDR does not see

Stand up fleet visibility and policy in days — then expand into investigation and continuous monitoring as you grow.
