VPN: Virtual Private Network in Cybersecurity
VPN stands for Virtual Private Network. A VPN creates an encrypted tunnel between a device and a network over the public internet. It protects data in transit and masks the user's IP address.
How VPN Is Used in Cybersecurity
Cybersecurity teams deploy VPNs to secure remote access to corporate networks. Incident responders verify VPN logs during breach investigations to trace lateral movement. Security architects evaluate VPN vs. zero-trust alternatives for network access control.
What VPN Means for Your Cybersecurity Career
VPN as an enterprise control is being displaced by zero-trust network access (ZTNA) in most large-organization architectures per Gartner's 2024 guidance and CISA's zero-trust maturity model. The career angle: candidates interviewing for security-architect or security-engineer roles in 2026 should be ready to discuss the tradeoff (VPN's perimeter assumption vs ZTNA's per-request authorization) rather than treat VPN as a standalone competency. The exception is the SMB market and consumer-VPN engineering, where VPN remains the dominant architecture.
