What Is a Data Breach? Impacts on Your Small Business

What Is a Data Breach and How Can It Impact Your Small Business?

If your business stores or collects information from customers, suppliers, partners or anyone else, you’re likely a potential target for a data breach.  A data breach occurs when someone unauthorized steals or accesses data like personal records, intellectual property or even financial information.

What is a Data Breach?

In a nutshell, a data breach is a cyber security issue where information falls into the wrong hands.

Even brick and mortar stores do some part of their business online these days. Technology has moved the dial toward an environment where there’s an overwhelming amount of information in the hands of businesses. That opens the door for data breaches from a variety of bad actors.

Data breaches can originate from a variety of sources from disgruntled ex-employees to loyal employees who answer phishing emails by mistake to professional cyber criminals. Each of these groups and some others can have a devastating effect on your business. If you think it can’t happen to you, consider the fact 50 percent of small businesses reported experiencing data breaches between 2015 and 2016.

A recent report from Verizon indicates a full 75 percent of these cyber crimes are committed by outside parties.

How Data Breaches Can Impact Your Small Business

So, how do these data breaches impact your small business? The consequences fall under three main categories.


Even if the breach is contained and fixed, the cost to your businesses’ reputation can be big. For example, if customer purchase and personal information gets stolen, customers might go and shop somewhere else where they feel more comfortable.


Hackers can access bank account information or even crash your small business website. The first scenario means they can drain your accounts. With a website that’s down completely, you lose revenue until it’s back up again.


Losing money and credibility in the marketplace is bad enough. However, having your ideas, templates and blueprints stolen can damage the ability of your company to grow. Intellectual property is quite often another casualty of data breaches.

The Scope of Data Breach Threats Today

The digital age has ushered in unparalleled connectivity and convenience for businesses, but it has also opened up new vulnerabilities. A data breach, essentially unauthorized access to confidential information, poses a significant threat not just to multinational corporations but to small businesses as well.

The consequences of such breaches extend beyond immediate financial loss, potentially impacting a company’s long-term reputation and customer trust.

Emerging Threats and Vulnerability Points

As technology evolves, so do the methods employed by cybercriminals. Small businesses must be aware of emerging threats such as sophisticated phishing schemes, ransomware attacks, and insider threats.

Vulnerability points can range from weak passwords and outdated software to more insidious risks like compromised smart devices connected to the business network.
