Network Extension (iOS)

For specialized enterprise deployments, Network Extension can provide VPN-like tunnels and managed connectivity. This requires Apple entitlements and is not suitable for most consumer apps.

When to consider it

• Always-on connectivity requirements
• Managed enterprise environments
• Custom tunneling or traffic shaping needs

Notes

• Entitlements require Apple approval.
• Design for graceful fallback when NE is unavailable.
• Pair with security best practices at the application layer.
