What a VPN does for radiology data and why it matters

Protects patient PHI during remote access to PACS, RIS, EHRs, and cloud storage
Encrypts data in transit so even if a network is compromised, the information remains unreadable
Helps enforce access controls, authentication, and auditing across devices and sites
Reduces risk on public or unsecured Wi-Fi in clinics, rural facilities, and during patient transport or home reading sessions
Supports compliant remote work for radiologists, technologists, and researchers

Key features healthcare teams should prioritize in a VPN

Strong encryption: AES-256 is the de facto standard for protecting PHI
Robust authentication: multi-factor authentication MFA and centralized identity management
No-logs policy and auditability: you want providers that can demonstrate privacy controls
Data residency and server locations: select vendors with strategic regions to meet data sovereignty rules
Kill switch and DNS leak protection: ensure your device doesn’t expose traffic if the VPN drops
Split tunneling with safeguards: useful for high-bandwidth tasks but must be configured to prevent PHI leakage
Concurrent connections and device support: cover desktops, laptops, tablets, and mobile devices used by clinicians
Business-oriented features: dedicated IP options, VDI integration, SOC 2/ISO 27001 compliance, and admin controls
Reliability and support: healthcare-grade SLAs, 24/7 support, and fast incident response
Compatibility with remote reading workflows: seamless access to PACS/RIS with minimal latency

VPN protocols explained what to know for healthcare

OpenVPN: widely adopted, solid security, configurable for UDP fast or TCP stable. Great for site-to-site and remote access, but can be heavier on devices.
WireGuard: modern, lean codebase, fast performance, easier to audit, and improves mobile experiences. Often paired with a company’s own implementation e.g., NordLynx by NordVPN for better privacy controls.
IKEv2/IPsec: strong performance on mobile devices, good stability when moving between networks, but may require more setup for enterprise scale.
L2TP/IPsec: legacy option with decent compatibility but generally slower and harder to manage at scale.
Practical takeaway: for healthcare, prioritize OpenVPN or WireGuard-based solutions with MFA, strong key exchange, and a clear data-privacy policy. WireGuard-based options or VPNs using WireGuard with a privacy-preserving layer are increasingly common for fast, secure remote access.
