What is a VPN and how does it work?
A VPN creates an encrypted connection between a supported device or application and a VPN server. Senton operates servers in 50+ countries, so the traffic we protect exits through an address of your choosing rather than the one your own connection hands out.
Your connection becomes more private and better protected on whatever network you happen to be using. However, a VPN does not make you anonymous online, nor does it protect you from all online threats.
- Encrypted connectionSupported traffic is protected between your device or browser and the VPN server.
- A different public IPWebsites generally see the VPN server address for eligible protected traffic.
- Location choiceYou can connect through supported locations in 50+ countries.

What does VPN mean?
A Virtual Private Network creates a protected route between a supported device or application and a VPN server. That server then becomes the public endpoint websites see for eligible traffic.
In simple terms, a VPN creates a protected route between you and the internet.
How a VPN works
A simple way to protect your connection and your privacy.
- 1You connectOpen Senton on a supported platform and pick an available VPN location.
- 2Supported traffic is encryptedFrom here the app takes over, encrypting eligible traffic between your device or browser and the VPN server.
- 3It travels through the VPN networkThe server makes the request to the website or online service that you are visiting, on your behalf.
- 4The website sees the VPN addressFor eligible traffic, the website generally sees the public IP address of the VPN server instead of your own.
The tunnel ends at the VPN server. Beyond it, HTTPS and the site’s own encryption do the work, which is why the padlock in your browser still matters.
What changes when you connect?
Some things change straight away. Others do not change at all.
- The public IP used by protected traffic
- The country or region worked out from that IP
- The route your traffic takes to reach a service
- What your provider can see about encrypted destinations
- The network a website thinks your connection belongs to
- Accounts you are signed in to
- Cookies already stored in your browser
- Your browser fingerprint
- Your device GPS position
- Your device time zone
- The country on your payment profile
- Your app-store country
- Anything you type into a website yourself
- Traffic you have excluded through Bypasser
A VPN changes the network connection. It does not change every identity or location signal on the device.
What can a VPN help with?
More privacy, more choice, and more control over what you share.
What a VPN cannot do
Plenty is claimed for VPNs that is not true. A VPN does not automatically do any of the following.
- Make you anonymous
- Remove cookies already on your device
- Remove your browser fingerprint
- Secure a device that is already compromised
- Stop phishing
- Prevent every malware infection
- Protect a weak password
- Hide what you type into a website
- Change your physical GPS location
- Guarantee access to any particular service
- Make your internet faster
- Replace antivirus software
- Replace good account security
A VPN is one privacy and security tool, not a complete online-safety system.
Browsing with and without a VPN
See the difference a VPN connection makes.
- Websites see the public IP your provider or network hands out
- Location estimates generally point at that connection
- Your provider or local network handles the connection directly
- HTTPS may still encrypt the contents of the sites you visit
- Accounts, cookies and fingerprinting apply exactly as before
- Eligible traffic travels through the encrypted tunnel
- Websites generally see the VPN exit address instead
- Location estimates generally point at the location you chose
- Your local network sees a connection to the VPN endpoint
- Accounts, cookies and fingerprinting still identify you
Who may find a VPN useful?
If you use the internet away from home, a VPN can help.
Common reasons people use a VPN
Does a VPN affect internet speed?
It can. Encryption takes work and your traffic travels further, so some extra delay is normal. How noticeable it is depends on several things at once.
- Your own internet connection
- Your device
- How far away the VPN location is
- How busy that location is
- Congestion on the wider network
- The protocol in use
- The website or service itself
- Whether you are on Wi-Fi or mobile data
A nearer location usually feels more responsive, but no VPN can promise zero impact. See Quick Connect, Packet Size Optimization and the server list.
What encryption protects, and what your provider still sees
Supported data is protected while it travels between your device or application and the VPN server, which stops others on the same network reading it easily. Past the VPN server, HTTPS takes over.
Learn about WireGuard- Which sites or services you contact at network level
- Your DNS lookups, depending on how they are configured
- When you connect and for how long
- How much data you move
- The public IP assigned to you
- That your device is connected to a VPN endpoint
- When you connect and for how long
- How much data you move
- The VPN server's address
What it cannot ordinarily do is read the contents of properly encrypted VPN traffic.
Is using a VPN legal?
VPN use is lawful in many countries, but the rules differ by country and change over time, and a small number of countries restrict or license them. A VPN also never makes an unlawful act lawful.
Our guide on where VPNs are legal goes country by country. It is general information, not legal advice.
How Senton VPN approaches everyday privacy
Use Senton on supported platforms
The Senton Android application protects supported traffic at device level, and it is available on Google Play and through the Aurora Store.
The Chrome extension protects supported traffic passing through the browser, covering Chrome rather than the whole computer, and it is available in the Chrome Web Store.
These are the applications available today. What each one covers differs, so the pages for individual features say which platform they apply to.
What is a VPN — frequently asked questions
A VPN creates an encrypted connection between a supported device or application and a VPN server. That server then talks to websites on your behalf. For eligible traffic, websites generally see the exit address of the VPN server rather than the public IP your own connection would present.
VPN stands for Virtual Private Network. Virtual in that the connection is created in software rather than over a dedicated cable. Private because supported traffic gets encrypted in transit between your device and the VPN server. Network because your device connects to a remote server that reaches the internet on your behalf.
A VPN encrypts your internet connection and changes the public IP address websites see, which keeps more of your online activity private. It protects supported traffic on public Wi-Fi networks and makes it harder for networks and websites to tie your browsing to your own connection. It also lets you reach the internet through a supported location in another country.
For eligible traffic, a website generally sees the VPN exit address rather than your public address. For traffic that the app does not protect, or that you have chosen to exclude through Bypasser, the website continues to see your normal address.
No. This one matters, so we will not dress it up in corporate language. Using a VPN changes the route your device takes to the internet, and it changes the public IP used for supported traffic. It changes nothing about the accounts you are logged into, the cookies already stored on your device, your browser fingerprint, or whatever you type into a website yourself.
A VPN protects supported traffic between your device and the VPN endpoint. This is the connection that others on your network would otherwise be closest to. It does nothing to secure a device that may already be compromised, and nothing to stop you handing information to a website directly.
A VPN changes the location that websites work out from your IP address, for eligible traffic. It does not change your device GPS position, your time zone, the country on your payment profile or your app-store country. Each of those is a separate signal, and they do not change.
Generally yes. Your provider can usually see that you are using a VPN, when you connected, how long you were connected and how much data you moved across it. What it cannot ordinarily do is read the contents of properly encrypted VPN traffic.
No, and a VPN is not a substitute for antivirus software. Safeweb helps by reducing requests to domains known for advertising, tracking or worse, but a VPN will not prevent every infection and cannot repair a device that is already compromised.
The Senton Android application and the Chrome extension are available now. The iPhone and iPad application is pending, and the Windows, macOS and Linux applications are coming soon. Each application covers something different, so the individual feature pages indicate which platform they apply to.
