The Plain English Version

A VPN creates an encrypted tunnel between your device and a network. When you connect via VPN, your internet traffic is encrypted and routed through a secure server, protecting it from eavesdropping.

For businesses, VPNs typically allow remote workers to securely access company resources as if they were in the office. The connection is encrypted, so even on public Wi-Fi, your data is protected.

Business VPN vs Consumer VPN

Business VPN: Connects remote workers to your company network. Provides secure access to internal resources, files, and applications.

Consumer VPN: Hides your IP address and encrypts your browsing. Popular for privacy and accessing geo-restricted content.

Why Businesses Need VPNs

  • Secure remote access - Staff can access internal systems from anywhere
  • Protected communications - Data encrypted in transit
  • Site-to-site connections - Securely link multiple office locations
  • Compliance requirements - Many frameworks require encrypted remote access

VPN Security Considerations

VPNs are not perfect security. If an attacker compromises a device with VPN access, they get network access too. This is why VPNs should be combined with MFA and why many organisations are moving toward zero trust approaches.

Also ensure: strong authentication (MFA required), up-to-date VPN software, proper logging, and split tunnelling decisions based on security needs.

The Shift Beyond VPN

Traditional VPNs grant broad network access once connected. Modern zero trust approaches provide more granular access - users get access to specific applications rather than the entire network. This limits damage if credentials are compromised.

For many SMEs, VPNs remain practical and effective, especially with MFA. But consider whether you need full network access or whether application-specific access would be more secure.
