Most IT teams have a good handle on installed applications, operating systems, and managed devices. But there’s one area still flying under the radar: browser extensions.
While small and easy to install, extensions are powerful. They often have access to everything a user sees and does online, including emails, cloud apps, internal tools, and passwords. For many organizations, this visibility gap has become a critical blind spot.
And like all blind spots in IT, it’s only a matter of time before it becomes a problem.
Browser Extensions: The Overlooked Entry Point
Extensions operate in a gray area between sanctioned tools and Shadow IT. They’re often installed by users without oversight. A productivity add-on here. A password manager is there. Before long, even regulated environments have dozens, if not hundreds, of active browser extensions with unknown origins, unknown permissions, and unknown impact.
Some may just be slowing down performance. Others may be quietly capturing sensitive data, injecting ads, or redirecting users to unsafe domains.
Without visibility, IT can’t distinguish helpful tools from dangerous liabilities.
The Shadow IT Link
Shadow IT isn’t limited to full applications or devices. In fact, browser extensions are often the most common form of unapproved software.
Why?
Because they don’t trigger the usual software deployment processes. They’re installed directly by end-users through browser stores, bypassing traditional controls. That means:
- No central approval
- No oversight of permissions
- No awareness of what’s in use
And yet, these same extensions can read email content, capture login credentials, modify web content, or even connect to external servers.
Where the Real Risks Lie
Let’s look at what’s really at stake:
- Data leakage: Malicious or compromised extensions can quietly export sensitive information to third parties.
- Compliance violations: If your organization handles regulated data (PII, health info, customer data), unauthorized access through extensions can trigger serious compliance failures.
- Security breach vectors: Many high-profile attacks began with something as simple as a compromised browser extension.
- Performance issues: Poorly built extensions can degrade user experience and create unnecessary support tickets.
All of this, happening invisibly under IT’s radar.
What IT Teams Should Do
- Acknowledge the blind spot. Understand that traditional software inventory tools won’t catch browser extensions unless explicitly built to do so.
- Assess the current state. Begin by investigating how many extensions are in use, on what browsers, and by which teams.
- Define policy and guardrails. Not all extensions are bad, some improve workflows. But you need a clear policy outlining what’s allowed and what’s not.
- Monitor continuously. Like any other software risk, visibility must be ongoing, not just a one-time audit.
