Security and Technology

Last updated: March 2026

VPN Protocols

ASMO360 VPN uses multiple encryption protocols to ensure reliable and stable connections.

TrustTunnel

• Transport: HTTP/2
• Encryption: TLS 1.3
• Platforms: iOS, Android, macOS
• Feature: Disguises VPN traffic as regular HTTPS — effective in networks with active VPN filtering and blocking

VLESS + Reality

• Type: Primary protocol
• Platforms: Android, Windows, Linux
• Feature: Advanced masking technology where traffic is indistinguishable from regular TLS connections to popular websites

VLESS + WebSocket TLS

• Type: Fallback protocol
• Platforms: Android, Windows, Linux
• Feature: Works through standard port 443, passes through most corporate firewalls

Auto-Failover

If the primary protocol becomes unavailable, the app automatically switches to the fallback — without user intervention. Availability checks occur every 60 seconds.

Leak Protection

DNS Leak Protection

All DNS queries are encrypted via DNS-over-TLS (DoT) and sent through the VPN tunnel. DNS servers used:

• AdGuard DNS (primary)
• Cloudflare DNS (fallback)
• Google DNS (fallback)

The device's system DNS resolver is not used when VPN is active — DNS leak is eliminated.

IPv4 / IPv6

• IPv4: All traffic is routed through the VPN tunnel
• IPv6: On Android — routed through the tunnel. On iOS — not routed (servers operate via IPv4)

Kill Switch

• Android: Implemented at two levels — in-app (traffic blocking on disconnect) and via system Always-On VPN
• iOS: Automatic reconnection on connection drop (On Demand Rules)

Encryption

Server Infrastructure

• Location: Europe
• Own DNS server — no user query logging
• Connection logging disabled on VPN servers
• Automatic log rotation — system logs deleted within 7 days

Jurisdiction

Republic of Armenia. Armenia is not a member of any surveillance alliances (5/9/14 Eyes) and has no legal requirements for mandatory data retention by VPN providers.
