Virtual private networks (VPNs) have become an indispensable tool for protecting your online privacy and security. By routing your traffic through an encrypted tunnel, a VPN allows you to browse the web anonymously, access restricted content, and prevent snoops from tracking your activities.

ExpressVPN is one of the most popular and highest-rated VPN services available today. But how exactly does ExpressVPN work under the hood? And what benefits does using the VPN offer for real-world users?

This in-depth guide will provide a complete overview of ExpressVPN, both from a technical perspective and user experience. Read on to learn:

I. Introduction to VPNs

Let’s start with a quick introduction to what virtual private networks are and their key capabilities.

A. Definition of a VPN

A virtual private network, or VPN, is a type of software that encrypts your internet traffic and routes it through a remote server run by the VPN provider. This creates a secure “tunnel” between your device and the server.

By connecting through a VPN server, your original IP address and location are concealed. This allows you to browse the web anonymously and evade geographic content restrictions.

B. Purpose of a VPN

There are several core purposes and benefits provided by virtual private networks:

  • Privacy – Preventing internet service providers (ISPs), government agencies, and snoops on public WiFi from monitoring your online activities.
  • Anonymity – Masking your true IP address, location, and identity online.
  • Security – Encrypting data to protect against hacking attempts and theft of sensitive information.
  • Accessibility – Bypassing geographic restrictions to view content blocked in certain countries.
  • Remote access – Securely connecting to a business or home network from anywhere in the world.

C. Introduction to ExpressVPN

ExpressVPN is one of the most prominent VPN services on the market, used by millions of customers globally across over 94 countries. It was founded in 2009 and offers a wide array of security and privacy features.

Some core features and capabilities provided by ExpressVPN include:

  • Uses powerful 256-bit AES encryption.
  • 3,000+ VPN servers located in 94 countries.
  • Fast connection speeds for HD streaming and downloads.
  • Allows P2P/torrenting activity across all servers.
  • Apps for all major platforms like Windows, Mac, iOS, Android, routers, and more.
  • Includes advanced features like split-tunneling, kill switch, and TrustedServer.

Next, let’s take a deep dive into how ExpressVPN delivers these capabilities under the hood.

II. Functioning of ExpressVPN

Now that you’re familiar with the definition and purpose of VPNs, let’s explore the technical details of how ExpressVPN works to secure your connection and protect privacy.

A. Network Connections

When you launch the ExpressVPN app and connect, it will establish an encrypted network connection in the following sequence:

  1. The ExpressVPN client on your device initiates a connection request to the nearest high-performance VPN server location based on your true location.
  2. The VPN server verifies your credentials and authorizes the connection.
  3. Your device is assigned a new virtual IP address from the VPN server’s network. This masks your true public IP address.
  4. An encrypted tunnel using the AES 256-bit algorithm is established between your device and the server.
  5. Your internet traffic is encrypted and routed through the VPN tunnel to the server, which then forwards it out to the public internet.
  6. When data is returned to the VPN server, it travels back through the encrypted VPN tunnel to your device.

This allows you to browse the web and access content using the IP address and location of the VPN server rather than your own. Your traffic is invisible to the public network.

B. Data Encryption

ExpressVPN employs AES 256-bit encryption to secure the connection between your devices and its VPN servers. This is an extremely robust encryption standard used by militaries and governments worldwide.

Some key capabilities of AES 256-bit encryption include:

  • Uses a 256-bit key to encrypt data, making it virtually impossible to decrypt without the key.
  • Rapidly encrypts data at high speeds, maintaining fast connection speeds.
  • Highly secure against brute force attacks due to the long 256-bit key size.
  • Flexible and secure enough for encrypting any kind of data in transit.
  • FIPS 140-2 certified and considered military-grade encryption.

In summary, the AES 256-bit protocol used by ExpressVPN ensures all your traffic is securely encrypted and cannot be read if intercepted.

C. Server Locations

ExpressVPN offers an extensive network of over 3,000 servers across 94 countries worldwide. This allows you to choose to connect through one of 160 locations to mask your whereabouts.

Popular server locations include United States, United Kingdom, Canada, Australia, France, Germany, Japan, and Singapore. You can connect to any location you wish.

Having servers all around the globe offers several benefits:

  • Lets you “appear” to browse from different countries.
  • Allows bypassing geographic restrictions and censorship.
  • Improves connection speeds by routing you through nearby servers.
  • Increases privacy protections compared to using a single location.

With thousands of options worldwide, ExpressVPN provides maximum flexibility to change your virtual location.

D. TrustedServer Technology

ExpressVPN employs an advanced VPN server system called TrustedServer to enhance privacy and prevent physical data tampering.

Here’s an overview of how TrustedServer works:

  • VPN server software runs directly on the bare metal server hardware, rather than virtual machines.
  • Servers have no storage drives, reducing the risk of data theft if a server is ever seized.
  • All software is installed on read-only media, preventing malware or rootkits from persisting on the system.
  • Minimal logging policy to avoid tracking user activity and connection timestamps.
  • Automatic security updates every two hours and firmware validated using cryptographic hashes.

In summary, ExpressVPN’s proprietary TrustedServer technology significantly strengthens server security and resilience against data capture.

So in summary, Outline combines the configurability of hosting your own VPN with the deployment simplicity of a commercial VPN service.

Next let’s go over the requirements for running Outline VPN.

Outline VPN Requirements

Before we begin installation, you’ll need the following:

A virtual private server (VPS) – This is a remote, cloud-hosted server you’ll install the Outline software on. Recommended specs:

  • At least 1GB RAM (2GB preferred)
  • Ubuntu 18.04/20.04 or Debian 10 OS
  • Enabled BBR congestion control

Outline Manager – Downloaded and installed on your local Windows, MacOS, or Linux computer. Used for server setup.

Outline Client – Installed on your devices like laptops, phones, etc. to connect to the VPN.

That’s the basic hardware and software you’ll need. Many VPS providers offer servers that meet Outline’s requirements, like Vultr, DigitalOcean, Linode, AWS Lightsail, and more.

Let’s dive into the step-by-step setup process next!

Step 1: Install a Virtual Private Server (VPS)

The first step is procuring a VPS that will host your Outline VPN server. This is an always-on, cloud-hosted virtual machine.

Many VPS providers allow customizing the server specs. I recommend the following:

  • At least 1GB memory (RAM), 2GB better
  • At least 2x CPU cores
  • Ubuntu 18.04/20.04 or Debian 10 OS
  • 40-60GB SSD storage
  • 1Gbps network speed

Popular VPS hosts like Vultr, DigitalOcean, Linode, and AWS Lightsail all offer servers that meet the above criteria for around $5-$10 per month.

Once you create the VPS, make note of the server’s IP address, root password, and SSH login details. We’ll need these to connect and install Outline.

I suggest starting with a basic, low-cost VPS configuration since you can always scale up later once your VPN is up and running.

Step 2: Install Docker on your VPS

Now that you have a VPS installed, the next step is to configure the server environment.

Outline uses Docker to simplify deployment across different distros. Docker packages software like Outline into a standardized “container” along with all its dependencies and configs.

Connect to your VPS via SSH, either through a terminal or SSH client like PuTTY. Then run the following scripts to install Docker:

Copy code

# Update package manager
sudo apt update
# Install dependencies
sudo apt install apt-transport-https ca-certificates curl software-properties-common# Add Docker’s GPG key
curl -fsSL | sudo apt-key add –

# Add the Docker repository to APT sources
sudo add-apt-repository “deb [arch=amd64] focal stable”

# Install Docker
sudo apt install docker-ce

# Verify the install
sudo docker run hello-world

You should see the Docker test print a confirmation message. Docker is now installed and running on your server!

Step 3: Set Up the VPN with Outline Manager

Outline Manager is the tool used to configure your VPN server. Download and install it on your Windows, Mac, or Linux computer from:

Once Outline Manager is installed, open the app and click “Start a new Outline server”. Choose “DigitalOcean” or “Other VPS” depending on your server provider.

You’ll be asked to enter the VPS IP address, root password, and an SSH public key for authentication. Outline Manager will handle the rest!

The app will automatically SSH into your server, install Docker images, download certificates, and configure the Outline VPN environment. This takes 5-10 minutes to complete.

When finished, Outline Manager will show confirmation that your VPN server is installed and include handy details like the domain name and IPs assigned to it.

Step 4: Create Access Keys for VPN Clients

Now that your Outline VPN is up and running on the VPS, the next step is creating special access keys to allow your devices to connect.

In Outline Manager, click “Add user” to generate a new access key. Give the key a name like “My Laptop” and hit Save.

This generates a long alphanumeric access key that authorizes a device to connect to your VPN. Anyone with this key can access your VPN, so keep it safe!

You can generate and manage as many keys as needed for all your devices. There’s no limit to the number of clients.

Step 5: Install Outline Client and Connect to the VPN

The Outline Client app allows you to connect your Windows, Mac, iOS, Android, or Chromebook device to your new VPN.

Download and install Outline Client from:

Once installed, tap the “+” icon to add a new VPN connection. Name it, and paste in the access key that Outline Manager generated for this device.

That’s it! Outline will connect and you’ll see confirmation that your traffic is being routed through your private VPN server. Browse and use the internet normally.

Repeat the Outline Client install process on any other devices you want to connect to your VPN. Just use the unique access key for each one.

Benefits of Using Outline VPN

Now that you have your own Outline VPN set up, here are some of the excellent benefits it provides:

You Control the Infrastructure
