VPN Watcher Review

We have looked at the subject of how to protect yourself when your VPN connection fails before. This an important issue, particularly for P2P downloaders who leave their BitTorrent clients running most of the time, and don’t want their VPN connection dropping when away from the computer.

The problem with the solutions we presented earlier was that they almost are all almost all for Windows, and there were no options available for mobile users. In addition to this, the only one which would close down a program when a VPN connection drops, then start it up again when reconnected, was VPN Check, a program we have found rather buggy in day-to-day use.

Enter VPN Watcher from. It will check your VPN connection ‘every half-second or less (up to 100ms) depending on current networking conditions’, and shut down any specified program immediately it detects a disconnect. As soon as you reconnect to a VPN server it will start the specified programs up again. We were particularly excited by the fact that according to, VPN Watcher is available for Windows, Mac OSX, iOS and Android! Unfortunately, as we shall see, the mobile offerings do not live up this promise.

VPN Watcher should work with any PPTP, L2TP or OpenVPN connection in Windows, but OpenVPN is not supported in the OSX version.

Note that VPN Watcher is proprietary software (i.e. its code is not open source and therefore can’t be independently verified), but as an Estonian we at least don’t think NSA spying is an issue (if such things worry you). There are both paid-for and free versions of the desktop software, with main the limitations of the free version being that the connection is checked every 500ms (rather than ‘up to’ every 99ms), and only one program can be controlled. If all you want to do is secure your P2P connection then the free version should be fine.


The mobile apps are free (but a waste of space).

VPN Watcher for Windows

We found the program very easy to . Just download, install and run, then to use OpenVPN select the ‘Tap-Win32’ adaptor installed by OpenVPN…


To find the name of this adaptor go to Control Panel -> Network and Internet -> Network Connections.


(If you can’t see it then you may need to reinstall your OpenVPN client, ensuring that the ‘Hide the TAP-Win32 Virtual Ethernet Adapter’ setting is unchecked on the ‘Choose Components’ screen.)

To add a program that you want down on disconnect and run on re-connect, right-click anywhere in the ‘Applications’ area, select ‘Add application’, and navigate to the desired program. The free version of VPN Watcher only allows you to add one program.

And that’s it! When we added uTorrent it started up immediately, and then shut down the second we disconnected our VPN service. Excellent.

Setting up PPTP (really not recommended) and L2TP is also very easy. The program comes with easy setup pre-sets for HMA, ibVPN, PureVPN, and StrongVPN (although we are not really fans of any of them)

Get the best for Windows

VPN Watcher for Android

After being very pleased with the Windows program, we were totally disappointed with the Android app, it does not act as a kill switch at all. All it does is for Blacklogic, HMA, ibVPN, ICanVPN and StrongVPN servers at a given location, provide ping times, and link to VPN providers’. Complete and misrepresented rubbish (and the iOS VPN app appears to be identical). We recommend using a good Android VPN app instead of using VPNWatcher.

We have somewhat mixed feelings towards VPN Watcher. The Windows version is very good, and we highly recommend it. We have not had the opportunity to test the Mac version, but as long as you can put up with the fact that it does not support OpenVPN, it probably works in a similar way (and is the only Mac VPN kill switch software we know of).

The mobile apps are a complete waste of time (we are tempted to say ‘con’, but as we didn’t pay any money for them that seems a bit harsh), and most certainly do not do the job we expected of them.

    For TigerVPN running on Windows 8.1: VPN Watcher Free lists my VPN connection, "Ethernet 2", as "Ethernet 2s Ada", which works, I suppose, though not precisely correct nomenclature. Ethernet 2 connects using TAP-Windows Adapter V9. "Ethernet 2 Properties" has all items checked except Microsoft Network Adapter Multiplexer Protocol. I don't know why it has File and Printer Sharing for MS Networks checked. I suppose the TigerVPN connection defaults to OpenVPN, since I get no opportunity to select PPTP or L2TP protocol. I am checking with TigerVPN support to make sure that they are using OpenVPN rather than PPTP or L2TP. TigerVPN is set to override any TCP access (as UDP). I don't know how that affects PeerBlock, which is only monitoring TCP/IP traffic for communications with malicious websites. PeerBlock still has a lot of TCP/IP traffic passing through, so the TigerVPN TCP override is not absolute. For Application in VPN Watcher, I have deluge.exe, with the appropriate path. Although Deluge has been running the whole time, I've never seen VPN Watcher list its status as "Running". The status of Deluge was originally "Stopped" and now is "Exited". I don't even know whether VPN Watcher is working, but given my ignorance of the application, I don't trust it yet. Thank you for any help you may provide.

      Hi Brian, > VPN Watcher Free lists my VPN connection, “Ethernet 2”, as “Ethernet 2s Ada”, which works, I suppose, though not precisely correct nomenclature. I imagine these are names that windows has assigned the adapters. You can check by going to Control Panel -> Network and Internet -> Network Connections. > I don’t know why it has File and Printer Sharing for MS Networks checked Probably so you can use your networked printer and access local network resources while connected to the VPN. > I don’t even know whether VPN Watcher is working, but given my ignorance of the application, I don’t trust it yet. You can easily test whether VPN Watcher is working simply by force-closing it (right-click its icon in the Task Bar -> Exit). If everything is working correctly, Deluge should shut down immediately.

    Why do not like HMA or PureVPN. I admit PureVPN's software and tech support suck, and HMA is way too expensive, but ... ?

      Hi R., - HMA is based in the UK and will hand over users' data to the authgorities at the drop of a hat - PureVPN - well, in addition to the negatives you have already listed, is not honest with its money back guarantee. Between them, I receive more complaints about HMA and PureVPN than all other services put together.

      Hi derek, It should do (but I am unable to check as I do not use ExpressVPN at this time).

    Does anyone know how to configure VPN Watcher for ExpressVPN?

    1. Douglas Crawford replied to Brad

      on April 2, 2015

      Hi Brad, The instructions provided in the article should work with ExpressVPN, but if you cannot get them to, then you can try VPNetMon or VPN Check, both of which are excellent. For more details, see our article on 5 ways to protect yourself when your VPN connection fails.

        The instructions in the article are for VPN Watcher for Windows. I haven't been able to figure out VPN Watcher for OS X yet. @blackVPN Could you help?
