Digital privacy, government censorship, and threats on public networks have positioned virtual private networks (VPNs) as a comprehensive and reliable solution compared to technologies like traditional proxies. Although proxies offer advantages in speed and simplicity, this document demonstrates why a VPN remains the preferred option in contexts where security, confidentiality, and traffic integrity are paramount. It analyzes the technical foundations, qualitative advantages, critical use cases, and scalable business models surrounding VPN offerings for consumers and enterprises.
From the rise of digital espionage to the increase in geographical restrictions on digital content, the modern user faces multiple threats and impediments in their digital life. While technologies like proxies allow for a certain level of anonymity and geographic access, they lack the level of encryption, encapsulation, and complete coverage that VPNs offer.
A VPN encrypts all operating system traffic, providing not only IP anonymity but also comprehensive protection against interception, tampering, or surveillance. This capability positions it as an essential tool for both privacy-conscious individual users and organizations seeking to protect their distributed networks.
A VPN (Virtual Private Network) creates an encrypted tunnel between the user\'s device and a remote VPN server. This tunnel encapsulates and encrypts all traffic (not just browser traffic), ensuring that no one—neither the ISP nor malicious actors on the network—can access or manipulate the data in transit.
Common protocols include:
- OpenVPN: Open source, flexible, secure.
- WireGuard: More modern, with better performance and a smaller attack surface.
- IKEv2/IPSec: High speed and stability on mobile connections.
Traffic travels from the user\'s device to the VPN server, which then acts as an exit point to the internet. Thus, the user \"inherits\" the server\'s IP address and browses anonymously.

| Feature | VPN | Proxy |
|-------------------------|--------------------------------|--------------------------------|
| Traffic reach | The entire operating system | Specific app (browser, etc.)|
| Encryption | Yes, end to end | Not necessarily |
| Wi-Fi protection | Yes, against sniffing and MITM | No |
| Data integrity | High | Null or low |
| Ease of detection | Difficult if well configured | Easy (common datacenter IPs) |
| DNS Protection | Yes (with DNS leak protection) | No Sources such as the Electronic Frontier Foundation (https://www.eff.org/) and Cloudflare (https://developers.cloudflare.com/cloudflare-one/) agree that VPNs are indispensable for complete security on public networks. CRITICAL VPN APPLICATIONS 4.1. Security on Public Wi-Fi Users connecting in cafes, airports, or hotels are vulnerable to sniffers, man-in-the-middle attacks, and DNS spoofing. A VPN eliminates this risk by encrypting all traffic.
4.2. Teleworking and Secure Remote Access
Many companies use VPNs so their employees can securely access intranets, servers, and databases. In these environments, a proxy is not enough.
4.3. Avoiding Surveillance and Censorship
In countries with censorship or active surveillance (China, Iran, Russia), VPNs with obfuscation (obfsproxy, Shadowsocks) allow free and secure access.
4.4. P2P Downloads
A VPN allows you to download torrents securely without exposing your public IP address. Many proxies block or filter P2P traffic.
4.5. Protection against doxing or IP exposure
Gamers, streamers, or influencers can protect themselves from DDoS attacks or doxing by using a VPN with a dedicated IP.

5.1. Full encryption
Unlike a proxy that only hides its IP address, a VPN encrypts everything (data, DNS, background traffic), ensuring privacy and protection against spying.
5.2. Lower legal or ethical risk
By protecting the user even in insecure contexts, the VPN acts as a defense tool against vulnerabilities without inducing misuse (unlike proxies used for spam or mass scraping).
5.3. More stable user experience
With technologies such as kill-switch, automatic reconnection, multihop and split tunnels, the modern VPN service offers superior stability to the proxy.
5.4.Consumer trust
VPNs are recognized as privacy tools by the general public and are endorsed by digital rights NGOs. Providers like NordVPN, Mullvad, ProtonVPN, and Surfshark position themselves as ethical brands.

A professional VPN service requires:
- Dedicated servers or VPS with good connectivity.
- TLS certificates, keys, and secure tunnel configuration.
- User control panel (OpenVPN Access Server, Radius, etc.).
- Bandwidth management and monitoring.
- Optional: Dedicated IPs, obfuscated servers, kill switch on the host side client.

The global VPN industry is estimated to be more than USD 44.6 billion in 2024, according to Global Market Insights. A compound annual growth rate of 15% is projected until 2030.
Growth is driven by:

- Privacy regulations (GDPR, CCPA).
- Increase in connected devices (IoT).
While proxies offer quick and specific solutions for tasks such as scraping or geolocation, VPNs are the only truly comprehensive tool when it comes to security, privacy, and digital identity protection. The ability to encrypt all traffic, protect the user on any network, and offer a consistent and reliable experience positions VPN as the superior choice in most scenarios.
For service providers, including VPN as the primary solution (complemented by a proxy in specific cases) represents a solid, ethical value proposition aligned with the growing demand for digital privacy.
