Why You Need a VPN in 2026
A VPN, or virtual private network, encrypts your internet traffic and routes it through a secure server, hiding your IP address and protecting your online activity from prying eyes. In 2026, this basic function has expanded into a comprehensive security necessity.
The threats are real:
- Data harvesting: Companies and AI tools are aggressively skimming user data.
- Surveillance: Governments worldwide are implementing age verification and content blocks that can be bypassed with VPNs—leading to potential VPN bans and restrictions.
- Cyberattacks: Remote workforces and cloud-first infrastructure have made VPNs a core security layer for enterprises and individuals alike.
- Quantum computing threats: "Harvest now, decrypt later" attacks mean your encrypted data could be vulnerable once quantum computers become viable.
The global VPN market reflects this growing need. It's projected to reach $155.9 billion by 2034, with a compound annual growth rate of 12.11%. VPN downloads have surged dramatically in regions facing internet restrictions—Proton VPN saw downloads jump 157% in a single day in June 2026.
Key VPN Trends Shaping 2026
Post-Quantum Encryption (PQE) Goes Mainstream
Quantum computing is the biggest cybersecurity topic of recent years, and 2026 is the year post-quantum encryption becomes standard. Without PQE capabilities, VPN encryption will be rendered futile.
Most top VPNs have already rolled out post-quantum encryption on at least one protocol. ExpressVPN was among the first to adopt it, while NordVPN continues to broaden its PQE coverage. Surfshark and Proton VPN have PQE on their 2026 roadmap.
