Why a VPN here?
Three risk scenarios specific to business trips: (1) a competitor's exec in the same hotel sniffs the Wi-Fi with a €40 Pwnagotchi — they intercept metadata (who talks to whom, duration, email sizes); (2) a compromised hotel staff member has router access and can MITM; (3) an Evil Twin in the lobby captures your corporate VPN credentials. A personal consumer VPN adds an extra layer between you and the hotel router — combinable with the corporate VPN.
Full procedure
- 1
Validate with IT before leaving
Check that using a personal VPN on top of the corporate VPN is allowed by IT policy. Some companies forbid it (split tunneling impossible).
- 2
Enable the personal VPN first
At check-in: Wi-Fi → captive portal → personal VPN → then corporate VPN on top. The double tunnel adds 5-15 ms latency, marginal on hotel fiber.
- 3
Disable file sharing
On macOS: System Preferences → Sharing → uncheck all. On Windows: Network settings → mark the Wi-Fi as "Public". Prevents your device discovery by other hotel guests.
- 4
Leak test before confidential emails
Open browserleaks.com/dns and browserleaks.com/webrtc. Verify no home IP appears. If WebRTC leaks, disable WebRTC in the browser.
Marriott and Hilton offer paid "Premium" Wi-Fi ($15-25 / day) creating an isolated VLAN per room — each guest is isolated from others. This neutralizes internal MITMs but not router compromise. Explicitly request "isolated VLAN" at reception.

Isn't the corporate VPN enough?
Not always. The corporate VPN encrypts traffic to internal servers, but split tunneling often lets traffic to cloud services (Microsoft 365, Salesforce, Gmail) go direct. On compromised Wi-Fi, that direct traffic is sniffable. A personal VPN encrypts everything, complementing the corporate one.
Is there a legal risk to using a personal VPN abroad?
In most business destinations (US, UK, DE, JP, SG, UAE with caveats), none. Check for China (obfuscated protocols required), Saudi Arabia (gray zone), Russia (officially restricted). See dedicated country guides on this site.
Does the VPN slow down Teams/Zoom video calls?
Slightly (+10-30 ms latency). On European hotel fiber, imperceptible. On limited Wi-Fi (Central Asia, low-end hotels), VPN can degrade quality from 1080p to 720p. Pick a VPN server geographically close to Teams DC (Europe: Amsterdam or Frankfurt).
