What Is a VPN? A Simple Guide for West Michigan Small Businesses
This article has been written by Greg Johnson

What Is a VPN and Why Do Small Businesses Use One?
Small businesses today rarely operate from a single office. Employees work from home, travel with laptops, and access business systems from many different networks.
That flexibility is convenient… but it also creates new cybersecurity risks.
One of the simplest tools businesses use to protect their data when working outside the office is a VPN.
Understanding how VPNs work — and when your business should use one — can significantly reduce your risk of data exposure.
What Is a VPN?
A VPN (Virtual Private Network) is a technology that creates an encrypted connection between a device and the internet.
This encrypted connection prevents outsiders from intercepting sensitive information such as:
- login credentials
- business emails
- financial data
- internal company files
In simple terms:
A VPN acts like a secure tunnel between your device and the systems you are accessing online.
Instead of sending information openly across the internet, the data travels through that protected tunnel.
For businesses, this means employees can safely access company systems even when they are outside the office network.
Why VPNs Matter More Than Ever
Modern businesses operate across many locations.
Employees may:
- work from home
- travel for meetings or conferences
- log into business systems from laptops or tablets
- connect through hotels, airports, or coffee shop WiFi
The challenge is that many public or shared networks are not secure.
Cybercriminals can sometimes intercept data traveling across these networks using widely available tools.
Without proper protection, information like passwords, emails, or client files may be exposed.
A VPN dramatically reduces this risk because:
VPN encryption prevents unauthorized users from reading or capturing your internet traffic.
For businesses handling sensitive information, this extra layer of protection is extremely important.
Real-World Example: Secure Remote Access for a Traveling Client
Recently, our team at IT Systems LLC in Grand Rapids helped a client prepare for business travel.
The client needed to access internal company systems while away from the office.
Before leaving, we configured a secure VPN connection so they could safely log into their network while traveling.
Without a VPN, connecting through hotel or airport WiFi could potentially expose login credentials or company data.
With the VPN in place, their connection remained encrypted and protected.
Situations like this are common for small businesses that rely on remote access.
What a VPN Protects
A properly configured VPN protects the data traveling between your device and the systems you access online.
This includes:
- business email access
- file transfers and shared drives
- remote desktop connections
- cloud applications
- login credentials
- sensitive company data
In practical terms:
A VPN protects the communication between your device and your business systems.
This protection is especially valuable when employees are outside the office network.
Signs Your Business Should Be Using a VPN
Many small businesses benefit from VPN access, particularly if they:
- have employees working remotely
- allow staff to travel with company laptops
- access internal servers or shared drives remotely
- handle sensitive client or financial data
- frequently use public WiFi networks
If any of these situations apply to your business, a VPN can significantly improve your security posture.
For many companies, VPN access becomes a standard part of secure remote work.
VPNs Are Only One Part of Cybersecurity
While VPNs are an important security tool, they are most effective when combined with other protections.
A strong cybersecurity strategy typically includes:
- multi-factor authentication (MFA)
- strong password policies
- secure cloud platforms like Google Workspace or Microsoft 365
- reliable data backups
- ongoing security monitoring
Cybersecurity works best as a layered approach, not a single tool.
Each layer helps reduce risk and prevent unauthorized access.
The Bottom Line for Small Businesses
Many cybersecurity incidents occur because businesses underestimate simple risks.
Employees connect to public networks.
Passwords are reused.
Security tools are not configured properly.
But small improvements, such as implementing a VPN, can dramatically reduce exposure.
A VPN is one of the simplest ways to secure remote access to business systems.
For businesses that travel, work remotely, or rely on cloud applications, it is often an essential part of modern cybersecurity.
