During a drive across the Prairies I used Guru VPN whenever I stopped at motels with open Wi‑Fi, and the app connected quickly each time and kept my email access private.
VPN Kill Switch: No Unprotected Traffic if the VPN Drops
Connections drop: Wi‑Fi gets patchy, your phone jumps to mobile data, a network hiccups. Guru VPN's Kill Switch blocks internet traffic the moment the VPN connection is lost, so nothing slips out unprotected while the app reconnects.
Blocks traffic instantly if the VPN connection drops
Keeps your real IP address from leaking during reconnects
Turn it on once in Settings — it works in the background

What is a VPN kill switch?
A VPN kill switch is a safety feature that cuts off your device's internet traffic if the VPN connection unexpectedly drops. Instead of quietly falling back to your regular, unencrypted connection, your device waits until the VPN is back, so your real IP address and online activity aren't exposed in the gap.
Without a kill switch, apps keep sending data when the VPN disconnects, often without you noticing. A messenger syncs, a browser tab refreshes, a cloud backup continues, all over your normal connection. The kill switch closes that gap.
How does a VPN kill switch work?
The kill switch watches your VPN connection continuously. Here is what happens when the connection is interrupted.
Step 1Protected
You're connected to Guru VPN. All traffic is encrypted with ChaCha20 and goes through the VPN server.
Step 2Connection drops
The VPN link is interrupted — for example, you switch from Wi‑Fi to mobile data or the signal weakens.
Step 3Traffic blocked
The kill switch stops internet traffic right away, so apps can't send data over your unprotected connection.
Step 4Reconnected
Once the VPN connection is restored, traffic resumes through the encrypted tunnel. No action needed from you.
Why choose a VPN with a kill switch
The best VPN with a kill switch is one you never have to think about: it reacts the moment the tunnel drops and lets traffic flow again as soon as you're protected.
Keep your IP address private
A dropped connection can reveal your real IP address to the sites and apps you're using. The kill switch stops that from happening.
Stay safe on public Wi‑Fi
Café, hotel and airport networks are where drops happen most and where unencrypted traffic is easiest to watch. The kill switch keeps you covered.
Protect background apps
Email, cloud backups and messengers sync even when the screen is off. If the VPN drops, they won't continue over an unprotected connection.
Travel with confidence
Moving between networks on the road means frequent reconnects. Your traffic waits for the VPN instead of leaking in between.
Private conversations stay private
Messages, calls and logins you start over the VPN won't suddenly continue over your regular connection.
Set it and forget it
Turn it on once and it works automatically. No need to watch the connection status.
When does the kill switch kick in?
Even a reliable VPN can lose its connection for reasons outside its control. These are the most common ones.
- Switching networks: moving from Wi‑Fi to mobile data, or between hotspots, briefly breaks the VPN connection.
- Weak or unstable signal: poor coverage, a crowded public network or a router that keeps dropping out can interrupt the tunnel.
- Network or server interruptions: restrictive networks, captive Wi‑Fi login pages or a temporary server issue can disconnect the VPN until the app reconnects.
How to test your VPN kill switch
A quick check takes about a minute and shows you the kill switch is doing its job.
If your real IP address appears at any point, make sure Kill Switch is on and contact our 24/7 support.
- Turn on Kill Switch in Settings and connect to Guru VPN.
- Open an IP-check website and note that it shows the VPN server's location, not yours.
- Interrupt the connection: switch Wi‑Fi off and on, or turn on airplane mode for a few seconds.
- While the VPN reconnects, try to load a page. It shouldn't load. Once Guru VPN reconnects, refresh the IP-check page: it should show the VPN location again.
How to turn on the Kill Switch in Guru VPN
Enable it once and it protects every connection after that.
Step 1
Open the app
Install Guru VPN on your iPhone, iPad or Android device and sign in.
Step 2
Go to Settings
Tap Settings in the Guru VPN app.
Step 3
Enable Kill Switch
Switch on Kill Switch, then connect to the VPN. From now on, traffic is blocked automatically whenever the VPN connection drops.
What the kill switch does — and what it doesn't
An honest look at what to expect.
 What it does |  What it doesn't do |
|---|---|
| Blocks internet traffic when the VPN connection drops | It doesn't stop the connection from dropping in the first place |
| Prevents your real IP address from leaking during reconnects | It doesn't protect traffic when you disconnect the VPN yourself |
| Works automatically in the background once enabled | It isn't available in the Windows and macOS apps |
| Resumes traffic through the tunnel when the VPN is back | It doesn't replace antivirus or careful browsing |

VPN without a kill switch vs with a kill switch
Without a kill switch
The VPN drops and your device switches to your regular connection. Apps keep sending data unencrypted, and websites can see your real IP address until you notice and reconnect.
With Guru VPN Kill Switch
The VPN drops and traffic stops immediately. Nothing leaves your device unprotected, and your connection resumes through the encrypted tunnel as soon as the VPN is back.

Millionsof satisfied users

average ratingTrustedworldwide
I started using Guru VPN to watch
lectures from a university portal that blocks some regions, and since switching to a suggested server the streams load quickly and stay smooth.
Cool app
After noticing my kids often connect to random Wi‑Fi at malls, I added Guru VPN to their phones and showed them the single connect button, and now they enable it before watching videos or using social apps in public places.
I love that I can set Guru VPN to
auto-connect on certain networks, so once configured, I don't have to think about it. It provides constant, silent protection in the background. I've never seen that feature before.
Buffer free
I use this app daily for streaming, and it never buffers. It's super fast, super secure, and I love that it doesn’t log anything. One tap and I’m fully protected! Couldn’t ask for more!
I installed Guru VPN to add an extra
layer of security when accessing corporate dashboards from home, and it now connects automatically before I log in to any work system or cloud service.
Simple use
The way this VPN works, I'd say it is perfect for everyday use! Whether I’m shopping online or watching geo-restricted media, Guru VPN keeps me anonymous and connected. Simple, trustworthy, and effective.
The best
On my daily train cọmmute I open Guru VPN, hit the single button, and read emails over the train Wi‑Fi knowing my connection is encrypted the entire ride.
I play competitive shooters where
every millisecond counts. This VPN's optimized servers actually improved my ping. I connect to a location closer to the game host, and my latency drops noticeably.
Must-have for remote work
As someone who works remotely, I rely on VPNGuru every day to secure my connection. It’s fast, stable, and I’ve never had an issue with dropped connections.
VPN kill switch FAQ
It blocks your internet traffic if the VPN connection drops unexpectedly. This stops your device from falling back to an unprotected connection and exposing your real IP address. Traffic resumes once the VPN reconnects.
For most people, yes. It costs nothing in everyday use and only acts when something goes wrong. It is especially useful on public Wi‑Fi and when you move between networks.
Yes. Kill Switch is included in the Guru VPN apps for Android and iOS, including iPhone and iPad. Turn it on once in the app settings and it blocks traffic automatically whenever the VPN connection drops.
No. Kill Switch is currently available in the Guru VPN apps for iOS and Android only. The Windows and macOS apps don't include it.
Usually the VPN connection has dropped and the kill switch is blocking traffic as designed: wait a few seconds for the app to reconnect, or tap connect again. If it happens often, try another server, check your signal and update the app. Still stuck? Our support team is available 24/7.
These networks often require you to sign in through a web page first, which the kill switch can block. Temporarily disconnect the VPN or switch Kill Switch off in Settings, complete the sign-in, then reconnect.
A system-level kill switch blocks all internet traffic on the device when the VPN drops. An app-level kill switch only closes or blocks specific apps you choose. Guru VPN's Kill Switch blocks traffic so nothing goes out unprotected while the VPN reconnects.
No. The kill switch reacts to unexpected drops. If you disconnect Guru VPN on purpose, your device uses your regular internet connection as usual.
