What Is a VPN?
A VPN, or Virtual Private Network, creates a secure, encrypted connection between your device and the internet. Instead of your data travelling openly across public networks, it passes through an encrypted "tunnel," making it far harder for anyone — including hackers on public Wi-Fi or your internet provider — to see what you're doing online or intercept sensitive information.
How Does a VPN Work?
When you connect to a VPN, your device first links to a VPN server operated by your provider or company. All your internet traffic is encrypted and routed through that server before reaching its destination. This does two things: it hides your real IP address (the destination sees the VPN server's IP instead), and it encrypts the data so it's unreadable to anyone who intercepts it in transit.
Personal vs Business VPNs
Consumer VPN apps are mainly used to protect privacy on public Wi-Fi and access geo-restricted content. Business VPNs serve a different purpose: they let remote employees securely access internal company resources — file servers, internal software, printers — as if they were sitting in the office, even from home or while travelling. This is essential for businesses with remote or hybrid teams, or multiple branch offices that need to share a network securely.
Do You Really Need One?
If your business handles sensitive client data, allows remote work, or operates across multiple locations, a properly configured VPN is one of the simplest ways to reduce the risk of data interception and unauthorised access. It should be paired with strong password policies, firewalls and regular security audits as part of a broader IT security strategy rather than used as a standalone fix.
