A Virtual Private Network (VPN) creates a secure, encrypted tunnel between your device and the internet. When you connect to a VPN, your internet traffic is routed through a remote server, hiding your real IP address and encrypting all data you send and receive.

How Does a VPN Work?

When you connect to Aultra VPN:

  1. Your device connects to our server using the WireGuard® protocol
  2. All your traffic is encrypted before leaving your device
  3. Your IP address is hidden – websites see our server's IP, not yours
  4. Your ISP can't see what you're doing – they only see encrypted data going to our server

Why Use a VPN?

Privacy Protection Your Internet Service Provider (ISP) can see every website you visit. A VPN encrypts this data, keeping your browsing history private.

Security on Public Wi-Fi Coffee shops, airports, and hotels are hunting grounds for hackers. A VPN encrypts your connection, protecting your passwords and personal data.

Access Content Anywhere Some content is restricted by location. A VPN lets you connect through servers in different countries, giving you access to a more open internet.

Avoid Tracking Advertisers and data brokers track your online activity using your IP address. A VPN masks your real IP, making tracking much harder.

VPN Protocols Explained

The two protocols you'll hear about most are WireGuard® and OpenVPN.

WireGuard® - Modern, lightweight protocol - Faster connections with less battery drain - Well suited to mobile devices - Used for every connection in Aultra VPN

OpenVPN - Battle-tested and widely audited - More configuration options - An older standard, still common in business VPNs

Is a VPN Legal?

VPNs are legal in most countries. They're legitimate privacy tools used by businesses and individuals worldwide. However, using a VPN doesn't make illegal activities legal – the same laws apply whether you're using a VPN or not.
