A useful travel VPN is one whose behavior you understand when the connection fails. The reassuring part is not the map of server locations or the large connect button. It is knowing whether traffic stops, reconnects or continues outside the tunnel when you close a laptop, change networks or encounter a hotel sign-in page.
This comparison shortlists Proton VPN and Mullvad for their documented controls, while keeping the employer-provided VPN as a separate category. It does not declare a fastest or most secure service. The available evidence here supports a choice of workflow, not an independent security ranking.
Establish whether you need a consumer VPN
Modern HTTPS already protects the contents of properly encrypted web connections. A consumer VPN adds a tunnel through a provider you choose; it does not make every website honest or prevent every form of tracking. The public Wi-Fi guide explains the distinction.
For work, start with the employer's requirements. A company VPN may provide access and enforce policies that a consumer VPN cannot replace. Installing a second service can add complexity without adding the protection the organization actually requires.
For personal use, name the reason for the purchase: reducing exposure to the local network, using a known tunnel across changing connections or another legitimate requirement. Once the purpose is clear, you can evaluate features against it rather than treating every advertised function as equally valuable.
Two documented approaches worth examining
| Candidate | Why consider it | What to check before relying on it |
|---|---|---|
| Proton VPN | Documented standard and advanced kill-switch behavior; a free plan for evaluating supported workflows | Exact operating system, app version, plan and available mode |
| Mullvad | Integrated desktop failure blocking and an optional stricter Lockdown mode; straightforward monthly pricing | Device registration limit, portal workflow and settings on each platform |
| Employer VPN | Approved access to business resources | Employer policy, supported destinations and official recovery route |
These are not interchangeable products. The company option is determined by access policy; the personal options require your own assessment of platform support and trust.
Understand what a kill switch actually does
Proton distinguishes its standard kill switch, which responds to an accidental disconnect, from advanced behavior that permits internet access only through the VPN. Its documentation is platform-specific, and some availability is marked beta. Do not assume a feature described for Windows behaves identically on an iPhone or Chromebook. Proton kill-switch documentation
Mullvad's desktop guide describes built-in blocking when the tunnel fails and an optional Lockdown mode that also blocks internet after a deliberate disconnect. Apps excluded through split tunneling can still connect outside that block. Check the routing exceptions alongside the switch itself. Mullvad desktop guide
Mullvad also documents a macOS startup limitation: some applications or system services can send traffic before the VPN service starts. Wait for the tunnel to connect before opening sensitive applications. Lockdown mode is therefore not a guarantee against every startup leak. Mullvad desktop limitations
Proton also documents Apple-platform limitations: some Apple-service DNS requests can bypass the VPN, and switching servers on macOS may briefly expose the real IP address. That makes the operating system a material part of the comparison. Follow the current platform guidance rather than treating a kill-switch label as a universal no-leak guarantee. Proton platform limitations
Read the settings as a failure policy. “Block when unexpectedly disconnected” and “block whenever no tunnel exists” solve related but different problems. Choose deliberately, then test the supported behavior on your own authorized device.
A settings label is not our independent verification. This article reports documented behavior; it does not claim a packet-level leak test.
Plan for hotel and airport sign-in pages
A guest network may need you to accept terms before it permits the VPN connection. A strict block can leave you apparently connected to Wi-Fi but unable to reach either the portal or the VPN server.
The NCSC identifies captive portals as a VPN deployment consideration. For a personal setup, use the provider's documented process and keep the portal interaction narrow. For a managed device, follow the organization's instructions or switch to an approved alternative connection. NCSC VPN guidance
Do not turn this into a blanket instruction to disable security whenever internet access is inconvenient. The distinction is a controlled, understood setup step versus an improvised bypass. After the portal, confirm the intended connection state before beginning the work that requires it.

Measure suitability against your real task
A speed result from a reviewer in another country is not a promise about your hotel, device or work application. VPN performance depends on the complete route, including the underlying connection and the destination service.
Before committing to a long subscription, use a legitimate trial or short commitment where available to test the routine you need. Open the actual work tools you are permitted to use, make a test call and observe reconnection after sleep or a network change.
Record the date, operating system, connection and server choice. Those details let you distinguish an app problem from a particular network or server route when you test again. A useful result is whether your actual call and reconnection routine work, not just whether one speed-test number looks impressive.
Do not run tests that violate company policy, access restrictions or local law. The objective is dependable approved access, not demonstrating that a restriction can be evaded.
Read audit claims narrowly
An audit can be valuable evidence, but its scope matters. An application review, a server assessment and a no-logs examination answer different questions. None automatically certifies every future release or every part of an organization.
A no-logs audit does not tell you whether your operating system has a routing exception, whether a portal will load, or how the next app release will behave. Use the report to assess the question it examined, then evaluate the practical controls separately.
When evaluating one yourself, look for the report date, examined version, scope, findings and remediation status. A badge without those details is weaker evidence than a readable report. Even a good report should sit alongside platform behavior and operational suitability.
Compare the cost of the commitment you will actually make
Mullvad's direct pricing page lists €5 per month including VAT, without requiring a longer commitment for that rate. That makes it easy to price a short trip in its billing currency. Currency conversion and payment arrangements still need checking. Mullvad pricing
For Proton, select the intended paid term and currency, then compare the amount due now and the renewal amount with the cost of the same period on Mullvad. No paid Proton price is quoted here, so this is not a price ranking. Its free tier can help evaluate supported behavior without implying that paid features are included. Proton pricing
For any provider, compare total cash due, not only the advertised monthly equivalent. A two-year commitment can have a low equivalent monthly figure while being an expensive way to cover one month abroad.
Our practical shortlist
Consider Proton when you want to evaluate its documented controls and plan options on your actual devices; consider Mullvad when a simple short commitment and its documented desktop blocking behavior fit your needs. Choose neither as a substitute for a mandated company connection.
The final selection should survive four questions: does it support the device, does it behave as expected when the tunnel fails, can you handle legitimate portal access, and is the commitment proportionate to the trip?
If those answers are unclear, another server-count comparison will not help. Resolve the workflow first. A VPN should make the connection easier to reason about, not add an unexplained layer between you and the work.
If your connection serves several devices, check the multi-device VPN comparison; installing an app on the phone does not establish what happens to laptop traffic. The public Wi-Fi safety guide supplies the wider sign-in and account-protection routine that a VPN alone cannot provide.
