Digital privacy, government censorship and threats to public networks position virtual private networks (VPNs) as an open and reliable solution compared to technologies such as traditional proxies. With proxies offering advantages in speed and simplicity, this document demonstrates why a VPN continues to be a preferred option in contexts where security, confidentiality and integrity of traffic are fundamental. It analyzes the technical foundations, qualitative advantages, critical use cases, and scaled business models surrounding consumer and enterprise VPN offerings. Embora technologies such as proxies allow a certain level of anonymity and geographic access, they do not possuem the level of cryptography, encapsulation and complete coverage that VPNs offer. A VPN encrypts all traffic of the operating system, providing not only IP anonymity, but also open protection against interception, adulteration or surveillance. This capability positions it as an essential tool for both individual users concerned with privacy 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 Internet Service Provider (ISP) or malicious agents on the network can access or manipulate data in transit.
Common Protocols includes:
- OpenVPN: Open source, flexible and secure.
- WireGuard: More modern, with better performance and smaller attack surface.
- IKEv2/IPSec: High speed and stability in connections move.
The traffic travels from the user\'s device to the server VPN, which acts as a gateway to the Internet. Assim, the user \\\\\\\"herda\\\\\\\" or endereço IP of the server and browse anonymously.

| Resource | VPN | Proxy |
|-------------------------|--------------------------------|--------------------------------|
| Scope of traffic | All or operational system | Specific application (browser, etc.)|
| Cryptography | Sim, from end to end | Not necessarily |
| Wi-Fi Protection | Sim, against sniffing and MITM Não |
| Integrity of two dice | High | Null or low |
| Detection facility | Difficult to be configured | Easy (common data center IPs) |
| DNS Protection | Sim (with protection against DNS leaks) | No sources such as the Electronic Frontier Foundation (https://www.eff.org/) and Cloudflare (https://developers.cloudflare.com/cloudflare-one/) agree that VPNs are essential for complete security on public networks. VPN CRITICAL APPLICATIONS 4.1. Public Wi-Fi Security Users connected to 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 that their employees can access secure intranets, servers and data banks. Nesses environments, a proxy is not sufficient.
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. Downloads P2P
A VPN allows you to download torrents with security without exporting 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 using a VPN with an IP dedicated.

5.1. Complete encryption
In contrast to a proxy that barely hides its IP address, a VPN encrypts everything (data, DNS, background traffic), guaranteeing privacy and protection against espionage.
5.2. Less legal or ethical risk
Ao protect the user itself in insecure contexts, a VPN acts as a defense tool against vulnerabilities without inducing unintended use (as opposed to proxies used for spam or mass collection of dice).
5.3. More advanced user experience
With technologies such as kill switch, automatic reconnection, multihop and split tunnels, the modern VPN service offers stability superior to the proxy.
5.4.Confidence consumer
As VPNs are only remade as privacy tools for the general public and only endorsed by NGOs with digital rights. Providers like NordVPN, Mullvad, ProtonVPN and Surfshark position themselves as ethical brands.

Um profissional VPN service require:
- Dedicated servers or VPS with good connectivity.
- TLS certificates, keys and secure tunnel configuration.
- User control panel (OpenVPN Access Server, Radius, etc.).
- Management and monitoring of network length band.
- Optional: IPs dedicated servers, obfuscated servers, kill switch without host client.

7.1. Monetization Models
- Monthly/Annual Assinatura (B2C).
- Business Access (B2B).
- Branded VPN (for resellers).
- VPN for niche markets (gamers, expats, day laborers).
7.2. Medium price
- General market: US$ 2 to US$ 10 per month.
- Dedicated IP: +US$ 3 to US$ 5 per month.
7.3. Added value
- Multi-hop VPN (server chain).
- Malware protection/DNS tracking.
- Integrated firewall.
- Multiplatform applications.
- Higher infrastructure cost than a proxy.
- Restrictions in certain countries that detect and block VPN traffic (Profound Package Inspection).
- Latency problems if the server is running very distant.
- Some Services (such as Netflix) block VPN IPs due to excessive use, but this may be mitigated with a change of servers. smart.
It is estimated that the global VPN industry will be more than US$ 44.6 billion in 2024, according to Global Market] Insights. It projects an annual growth rate of 15% by 2030.
O growth is driven by:
- Increased digital censorship.
- Privacy Regulations (GDPR, CCPA).
- Increase in connected devices (IoT).
Embora the proxies offer quick and specific solutions for tasks such as scraping or geolocation, as VPNs are the only truly open tool when it comes to security, privacy and protection gives digital identity. The ability to encrypt all traffic, protect users on any network and offer a consistent and reliable experience positions VPN as the top choice in most scenarios. For service providers, including VPN as a primary solution (complemented by a proxy in specific cases) represents a solid and ethical value proposition, aligned with the growing demand for digital privacy.
