What Is a VPN and Does Your Business Need One?

What Is a VPN?

A VPN (Virtual Private Network) creates an encrypted tunnel between your device and the internet. Instead of your web traffic going directly from your computer to the websites you visit, it first travels through a secure, encrypted connection to a VPN server. From there, it goes out to the internet.

Think of it like a private hallway in a public building. Everyone else is walking through the open lobby where anyone can see them. You're walking through a closed hallway that nobody can peek into. You still end up at the same destination, but no one can watch your journey.

When you use a VPN, two things happen:

Your internet traffic is encrypted — Anyone snooping on your connection (like hackers on public Wi-Fi) sees nothing but scrambled data
Your IP address is hidden — Websites see the VPN server's IP address instead of yours, adding a layer of privacy

When You Actually Need a VPN

Not every business needs a VPN for everyday use. But there are specific situations where one is important:

Using public Wi-Fi — Coffee shops, airports, hotels, coworking spaces. These networks are often unsecured, and it's relatively easy for someone on the same network to intercept your traffic. A VPN makes that interception useless.
Remote workers accessing business systems — If your employees work from home and need to access internal company resources (file servers, databases, internal apps), a VPN ensures that connection is secure.
Accessing sensitive data on the go — If you're reviewing financial reports or customer records from a hotel room, a VPN adds a layer of protection.
Working from countries with restricted internet — If you or your team travel internationally, some countries restrict access to certain websites and services. A VPN can help maintain access to the tools you rely on.

When You Probably Don't Need One

Here's the honest truth: most of the time, at home on your own network, you don't need a VPN for basic web browsing.

Modern websites already use HTTPS (that padlock icon in your browser), which encrypts the data between your browser and the website. Your ISP can see which websites you visit, but they can't see what you're doing on those sites.

If you're just browsing the web, checking email through a reputable provider, and using your own secured home Wi-Fi — a VPN adds a little privacy but isn't critical.

VPN companies spend a lot on marketing. They want you to believe you're in danger every second you're online without one. The reality is more nuanced.

Consumer VPN vs. Business VPN

There's a big difference between the VPNs advertised on YouTube and what businesses actually use:

Consumer VPNs (NordVPN, ExpressVPN, Surfshark):

Primarily about privacy and accessing geo-restricted content
Route all your traffic through their servers
Subscription-based, usually $3-12/month
Easy to set up on personal devices

Business VPNs (Cisco AnyConnect, WireGuard-based solutions, Cloudflare WARP for Teams):

About securing access to company resources
Can be configured to only route work-related traffic through the VPN (called split tunneling)
Managed centrally by the business
Can enforce security policies and access controls

Free VPNs: You Get What You Pay For

If a VPN is free, you're probably the product. Free VPN providers often:

Log your browsing data and sell it to advertisers
Inject ads into your browsing
Have slow speeds due to overcrowded servers
Provide weak or outdated encryption

There are exceptions — Cloudflare WARP is a free VPN-like service that's legitimate. Cloudflare makes money from business products, not from selling your data. WARP uses modern protocols and doesn't log your browsing activity.

The Modern Alternative: Zero Trust

The tech industry is actually moving away from traditional VPNs toward something called zero trust network access (ZTNA). Instead of creating a tunnel to your entire network, ZTNA verifies every single request individually. Cloudflare Access is a good example of this approach.

But for most small businesses, a straightforward VPN setup is still the practical choice.

The Bottom Line

Use a VPN on public Wi-Fi — always
Use a VPN for remote access to business systems — yes
Use a VPN for everyday browsing at home — nice to have, not essential
Never use a free VPN (except Cloudflare WARP) — just don't

VPN Protocols, Split Tunneling, and Zero Trust Explained

Let's go deeper into how VPNs actually work and where the technology is heading.

VPN Protocols: The Engine Under the Hood

A VPN protocol is the set of rules that determines how your data gets encrypted and transmitted. Different protocols offer different tradeoffs between speed, security, and compatibility:

WireGuard — The modern favorite. It's fast, lightweight, and uses state-of-the-art cryptography. The codebase is tiny (about 4,000 lines of code compared to hundreds of thousands for older protocols), which means fewer bugs and vulnerabilities. Cloudflare WARP uses WireGuard under the hood.
OpenVPN — The established standard. Open source, well-audited, and extremely configurable. Slightly slower than WireGuard but supported everywhere. Many business VPNs still use OpenVPN.
IPsec/IKEv2 — Built into most operating systems, which means it works without installing extra software. Common in corporate environments. Stable and fast, especially good at reconnecting when you switch between Wi-Fi and cellular.
L2TP/IPsec — Older and slower. Still works but there's no good reason to use it over the newer options.
PPTP — Ancient and broken. Don't use it. The encryption has been cracked and it provides essentially no security.

For most small businesses, WireGuard is the best choice. It's the fastest, most secure, and easiest to set up.

Split Tunneling: Not Everything Needs the Tunnel

By default, a VPN routes all your internet traffic through the encrypted tunnel. That includes your work email, but also your YouTube videos and Spotify streams. This can slow things down and put unnecessary load on the VPN server.

Split tunneling lets you choose which traffic goes through the VPN and which goes directly to the internet:

Traffic to your company's internal systems → through the VPN
Browsing the web, streaming, personal stuff → direct to the internet

This gives you the security benefits for work traffic without slowing down everything else. Most business VPN solutions support split tunneling.

Zero Trust Network Access (ZTNA): The VPN's Replacement

Traditional VPNs have a fundamental problem: once you're connected, you have access to everything on the network. If a hacker compromises one employee's VPN credentials, they can reach the entire internal network. It's like a building where the front door is heavily guarded, but once you're inside, every room is unlocked.

Zero trust flips this model. Instead of trusting anyone who's on the network, it verifies every single request:

Who is making the request? (identity verification)
What device are they using? (is it a managed, up-to-date device?)
What are they trying to access? (do they have permission for this specific resource?)
What's the context? (are they logging in from an unusual location or time?)

Every access request is evaluated independently. No blanket trust.

Cloudflare Access and Zero Trust

Cloudflare Access is one of the leading zero trust solutions, and it's surprisingly accessible for small businesses. Instead of setting up a traditional VPN, you put your internal applications behind Cloudflare Access. When someone tries to reach an app:

Cloudflare checks their identity (via your existing identity provider like Google or Microsoft)
It checks the device meets security requirements
It checks access policies you've defined
Only if everything passes does it allow access — to that specific application, not your whole network

The beauty: no VPN client to install, no network configuration headaches, and much better security. Users just log in through their browser.

Site-to-Site VPNs for Multi-Location Businesses

If your business has multiple physical locations (two offices, an office and a warehouse, etc.), a site-to-site VPN connects those networks as if they were one. Devices at Location A can access printers, file servers, and other resources at Location B seamlessly.

This is different from the remote-access VPNs we've been discussing. Site-to-site VPNs run between routers or firewalls at each location, creating a permanent encrypted tunnel between the two networks.
