VPN Tools & Interactive Security Explainers
Free VPN checkers, privacy tests and visual explainers to help you understand what your connection is doing.
Use our free VPN tools to check whether your VPN is working, view your public IP address, test for WebRTC leaks, run an internet speed test, inspect your browser details and spot red flags before trusting a provider. This hub also brings together our interactive VPN and cybersecurity explainers, covering topics like VPN tunnelling, split tunnelling, kill switches, DNS handshakes, DNS spoofing, ChaCha20 encryption, man-in-the-middle attacks and what your ISP may be able to see online. Start with a quick privacy check, then use the visual guides to understand the result.
Free VPN Tools & Privacy Checkers
Test your VPN connection, IP address, browser, speed and privacy basics in a few clicks.
Is My VPN Working?
Check whether your VPN connection appears active and whether your public network details look protected before you browse, stream or use public Wi-Fi.
CHECK YOUR VPNIP Address Checker
See the public IP address websites may see when you visit them. Use it before and after connecting to a VPN to check whether your visible location changes.
CHECK IP ADDRESSWebRTC Leak Test Tool
Run a quick WebRTC leak check to see whether your browser could expose network details that undermine your VPN privacy.
RUN LEAK TESTInternet Speed Test Tool
Test your connection speed before and after connecting to a VPN so you can understand the real-world impact on downloads, browsing and streaming.
TEST SPEEDWhat Browser Am I Using?
Check your browser, device and basic user-agent details. This is useful for troubleshooting VPN issues, website blocks and compatibility problems.
CHECK BROWSERVPN Red Flag Checker
Review warning signs before choosing a VPN, including vague privacy claims, unclear ownership, weak refund terms and missing security details.
CHECK VPN RISKSInteractive VPN & Cybersecurity Explainers
Understand VPN privacy, encryption, DNS, tunnelling and online threats with visual guides.
How Does a VPN Work?
Follow a simple visual explanation of how a VPN routes traffic, masks your IP address and creates a more private connection between your device and the internet.
OPEN EXPLAINERMan-in-the-Middle Attack
See how attackers can sit between you and a website on unsafe networks, and why encrypted connections and secure browsing habits matter.
VIEW GUIDEVPN Split Tunnelling
Learn how split tunnelling lets some apps use the VPN while other traffic stays on your normal connection, and when that setup can help or hurt privacy.
LEARN SPLIT TUNNELLINGCan Your ISP See What You Do?
Understand what your internet provider may see with and without a VPN, including domain lookups, traffic timing, encrypted websites and connection metadata.
SEE WHAT IS VISIBLEVPN Kill Switch
See how a VPN kill switch helps block traffic if the VPN connection drops, reducing the chance of your real IP address being exposed.
EXPLAIN KILL SWITCHESVPN Tunnelling
Break down how VPN tunnels wrap and move your data through a protected connection, and why tunnelling protocols matter for speed and privacy.
OPEN TUNNELLING GUIDEChaCha20 Encryption
Learn why ChaCha20 is used in modern security tools and how encryption helps protect data as it moves across networks.
LEARN ENCRYPTIONWhy Does a VPN Slow Internet?
Understand why VPNs can affect speed, including encryption overhead, server distance, protocol choice, device limits and network congestion.
EXPLAIN SPEED LOSSWhat Is DNS Spoofing?
Learn how DNS spoofing can misdirect traffic and why secure DNS behaviour matters when you are browsing, logging in or using public networks.
LEARN DNS SPOOFINGWhat Is a DNS Handshake?
See what happens when your browser looks up a website and how DNS requests connect domain names to internet addresses behind the scenes.
VIEW DNS GUIDEHow To Use These VPN Tools
A simple testing flow for checking privacy, speed and connection behaviour.
Check Your IP First
Open the IP checker before and after connecting to your VPN so you can see whether your visible IP address changes.
Run a VPN Check
Use the VPN working checker to confirm that the connection looks active and that your privacy setup is behaving as expected.
Test for Leaks
Run the WebRTC leak test to look for browser-level issues that may reveal details even when a VPN is connected.
Compare Speed
Run a speed test with and without the VPN so you can judge the real performance trade-off for browsing, downloads and streaming.
VPN Tools FAQ
Quick answers about VPN checks, IP tests, WebRTC leaks, speed tests and interactive explainers.
What can I check with these VPN tools?
You can check whether your VPN is working, view your public IP address, test for WebRTC leaks, run an internet speed test, check your browser details and review VPN warning signs before choosing a provider.
Are the VPN tools free to use?
Yes. The tools and explainers on this page are designed to be free, quick and easy to use without requiring a VPN subscription.
Which tool should I use first after connecting to a VPN?
Start with the Is My VPN Working tool, then check your IP address and run the WebRTC leak test. Together, those checks help confirm whether your VPN is hiding your real network details.
Can these tools tell me if a VPN is safe?
They can help spot technical problems and warning signs, but no single tool can prove that a VPN is completely safe. You should also review the provider’s privacy policy, ownership, logging claims, audits, app quality and security features.
Why include interactive explainers as well as checkers?
Checkers help you test your own connection, while interactive explainers help you understand what is happening behind the scenes, such as VPN tunnelling, DNS handshakes, encryption, kill switches and man-in-the-middle attacks.
Do VPN speed tests always show the full picture?
No. A speed test is a useful snapshot, but VPN performance can change depending on distance to the server, protocol, device, local network, time of day and server load. Testing more than once gives a clearer result.
What is a WebRTC leak test?
A WebRTC leak test checks whether your browser is exposing network information that could reveal your real IP address even while a VPN is connected. It is one of the quickest privacy checks to run after enabling a VPN.
Who are these tools for?
They are for anyone comparing VPNs, troubleshooting a VPN, learning how VPN privacy works, checking their IP address, testing speed, or trying to understand common online security risks in a simple visual way.
