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