The Most Overlooked Risk in Cybersecurity? Your Browser.

Most businesses today have some level of cybersecurity in place. You’ve got antivirus software running, your firewall is up, and maybe you’re even using a secure email gateway to block phishing attempts. That’s all good—but there’s one critical part of your environment that’s likely going completely unprotected: the browser.

And that’s a problem. Because your team spends nearly 90% of their workday inside a browser—logging into apps, accessing sensitive customer data, managing finances, even downloading files. (Source: Forrester, 2023)

But the browser isn’t just a workhorse—it’s also one of the most targeted and least secured entry points in your organization.

A Familiar Scenario: One Extension, Big Consequences

Picture this: a 25-person financial services firm in the Midwest. An employee installs what looks like a harmless browser extension to help manage their calendar. Unbeknownst to them, it includes a hidden payload that logs keystrokes and session cookies. Within days, attackers have access to their CRM—and client records.

It’s not an uncommon scenario. Breaches like these don’t always come from phishing emails or exposed RDP ports. Increasingly, they start in the browser.

Browsers Are Endpoints Now—But We’re Not Treating Them That Way

Here’s the reality: modern work happens in the cloud, and the browser is the front door. But while you may have controls in place for laptops or mobile devices, most organizations have no visibility or policy enforcement at the browser level. No way to block risky extensions, unsanctioned SaaS apps, or sensitive data being copied into the wrong tab.

That gap is costing businesses—especially SMBs.

According to the 2024 Verizon Data Breach Investigations Report, 76% of breaches in the financial sector began at the browser level. And it’s not just finance. Healthcare, education, manufacturing—they’re all increasingly targeted through browser-based exploits.

You Don’t Need a Giant Security Stack to Fix This

What makes this even riskier for SMBs is the misconception that fixing it means a massive investment. It doesn’t.

Unified Browser Security™ platforms like Acium give you real-time visibility, extension risk scoring, policy enforcement, and data protection—right inside the browsers your team already uses. No rip-and-replace, no complicated training. Just a missing layer filled in.

Think of it this way: you wouldn’t leave your front door unlocked just because you had a security camera. So why leave the browser wide open when it’s where all your critical work—and sensitive data—lives?

Want to Know If You’re at Risk?

We created a free checklist to help you uncover blind spots in your browser security strategy.

• Can you see what browser extensions your employees are using?
• Do you know which apps they’re accessing—and whether they’re safe?
• Do you have any protection in place if sensitive data is copied or leaked through a browser?

If you’re unsure, this checklist will help you identify the gaps and take the first step toward closing them.
