Free Wi-Fi Isn’t Always Free

I was at a restaurant the other night and the cellular signal inside the building was terrible. Like most people, my first instinct was to look for guest Wi-Fi so I could quickly look something up while waiting for my food.

I found a guest network, connected, and was immediately redirected to a login page. Instead of asking for a password, the service wanted me to sign in with one of my social media accounts. The platform was called SocialWiFi, and while I’m sure many people would have clicked through without a second thought, I closed the browser and put my phone away.

Whatever I wanted to look up could wait until I got home.

Maybe that makes me paranoid. After spending most of my career in cybersecurity, however, I’ve become increasingly selective about who I hand my information to and what I get in return. A few minutes of internet access simply wasn’t worth contributing another piece of information to a system designed to collect, analyze, and monetize personal data.

The Business of Knowing Everything

Most people understand that social media companies collect data. What many don’t realize is just how many organizations participate in the collection and exchange of information about consumers.

A restaurant offering free Wi-Fi may not care about your personal life. The company operating the Wi-Fi portal, however, likely cares about understanding customer behavior. Marketing firms care about understanding customer behavior. Data brokers care about understanding customer behavior. Advertisers care about understanding customer behavior.

Each organization may only possess a small piece of the puzzle, but modern technology allows those pieces to be combined in ways that would have been impossible twenty years ago.

Knowing that you visited a particular restaurant on a Tuesday evening isn’t especially valuable by itself. Knowing where you eat regularly, where you work during the day, where you live at night, which social media accounts you use, what websites you visit, and what products you buy begins to create a remarkably detailed profile. That’s where the value exists.

Nobody is making money from a single data point. They’re making money by collecting millions of them.

The Data Economy Most People Never See

We live in a world where information is bought, sold, enriched, and resold continuously. Data brokers maintain enormous databases containing information gathered from loyalty programs, marketing campaigns, public records, mobile applications, website tracking systems, social media platforms, and countless other sources.

Most consumers never directly interact with these companies. In many cases, they don’t even know they exist.

What starts as a rewards program at a grocery store may eventually become part of a marketing profile. A social media login for restaurant Wi-Fi becomes another data point. A mobile app that asks for more permissions than it needs contributes another piece of information.

None of these interactions feel significant at the time, which is exactly why they are so effective. The collection process is distributed across hundreds of seemingly harmless transactions that occur over many years.

By the time someone realizes how much information has been accumulated, the data has already been shared countless times.

Why This Matters to Business Owners

Many small business owners view privacy as a personal issue rather than a business concern. In reality, the line between personal privacy and business security has largely disappeared.

Attackers rarely begin by targeting firewalls or security software. They often start by researching people.

They look for social media profiles, personal interests, family members, employment history, locations, email addresses, and any other information that helps them build a profile of their target. The more information they can gather, the easier it becomes to craft convincing phishing emails, impersonate trusted individuals, or manipulate employees into taking actions they normally wouldn’t.

A criminal doesn’t necessarily need access to your business systems if they can convince someone that they are you.

We’ve seen countless examples of attackers impersonating executives, business owners, vendors, and trusted partners. In many cases, the attack succeeds not because the technology failed, but because the attacker knew enough about the target to appear legitimate.

Every piece of personal information available online makes that process easier.

Your Reputation Is Part of Your Security Program

One aspect of cybersecurity that doesn’t receive enough attention is brand protection. Business owners spend years building trust with customers, employees, and partners, yet much of that trust can be exploited by someone willing to impersonate them.

Imagine a criminal creating a convincing social media profile using publicly available information. Imagine customers receiving messages that appear to come from your business. Imagine vendors receiving fraudulent payment requests that seem legitimate because the attacker knows who they should contact and how your organization operates.

These scenarios happen every day.

The information used to make these attacks successful often comes from dozens of sources that seemed harmless when the data was originally collected.

When viewed individually, none of those data points appear dangerous. When combined, they can become surprisingly powerful.

The Negative You Can’t Measure

One of the reasons people struggle with privacy decisions is that the benefits are almost impossible to quantify.

I don’t participate in many loyalty programs. I rarely sign up for coupon clubs. I generally avoid handing out personal information unless there’s a clear reason to do so.

As a result, I almost certainly spend more money than someone who enthusiastically joins every rewards program available.

What I can’t calculate is what I’ve avoided.

How many robocalls never happened because my information wasn’t available?

How many spam emails never arrived?

How many phishing attempts failed because an attacker couldn’t gather enough information?

How many marketing databases don’t contain my information?

It’s impossible to measure a negative outcome. We can easily calculate the discounts we received, but we can’t calculate the problems that never occurred because we chose not to participate.

Convenience Always Has a Cost

The next time you’re presented with a social media login to access Wi-Fi, join a rewards program, or claim a discount, it’s worth taking a moment to ask a simple question:

If this service is free, how are they making money?

Sometimes the answer is harmless.

Sometimes it isn’t.

The point isn’t that every company collecting information is malicious. The point is that information has value, and many businesses are built around collecting, analyzing, and monetizing that value.

As consumers and business owners, we should understand that transaction before we agree to it.

Because once your information enters the data broker ecosystem, you lose control over where it goes next. And in a world increasingly driven by data, that information may eventually be used in ways you never anticipated.
