Virtual Private Networks (VPNs) are widely used to enhance online privacy, but misconceptions about their functionality persist among IT professionals and advanced users. This article clarifies common myths, providing accurate insights into what VPNs can and cannot do, ensuring informed decision-making for secure network configurations.
Understanding VPN Functionality
VPNs create encrypted tunnels between a user’s device and a remote server, masking the real IP address and shielding online activities from Internet Service Providers (ISPs). While VPNs are powerful privacy tools, their capabilities are often misunderstood, leading to unrealistic expectations or underutilization.
Myth 1: VPNs Provide Comprehensive Security
Reality: VPNs prioritize privacy over comprehensive security.
Originally designed for secure corporate network access, VPNs allowed remote employees to connect to company servers safely. Modern consumer VPNs, however, focus on privacy by hiding your IP address and encrypting traffic. The widespread adoption of HTTPS, which secures over 85% of websites, ensures that sensitive data like banking details is encrypted between your device and the website, reducing the need for VPNs to secure these transactions.
- HTTPS Impact: Most browsers display a lock icon for HTTPS-enabled sites, indicating secure connections. This makes VPNs less critical for securing online banking or e-commerce.
- Security Limitation: While hiding your IP address offers some protection against targeted attacks, it’s not a primary defense against hacking attempts.

Myth 2: VPNs Protect Against Hackers on Public WiFi
Reality: HTTPS secures public WiFi connections, but VPNs prevent browsing history tracking.
In the past, public WiFi posed significant risks due to unencrypted connections, enabling attacks like evil twin hotspots or WiFi sniffing. Today, HTTPS encrypts most website interactions, protecting sensitive data from interception. However, public WiFi providers can still track visited websites and sell this data to advertisers, a practice increasingly common under lax privacy regulations.
- VPN Role: A VPN prevents WiFi hosts from logging your browsing history, preserving privacy where HTTPS falls short.
- Government Surveillance: VPNs also mitigate risks of data collection by governments purchasing browsing data from WiFi operators.
Myth 3: Self-Hosted VPNs Offer Superior Privacy
Reality: Self-hosted VPNs often compromise privacy compared to commercial services.
Self-hosting a VPN server appeals to those wary of trusting commercial providers. However, this approach has significant privacy drawbacks:
- Unique IP Exposure: A self-hosted VPN server uses a single IP address tied directly to you, making it easier for websites to track your activity compared to commercial VPNs, where thousands share the same server IP.
- Provider Trust: Reputable VPN services implement no-logs policies and undergo independent audits, reducing the need to trust ISPs or server hosts that may log or sell data.
Commercial VPNs with features like no-logs policies and shared IPs offer stronger privacy protections for most users. Learn how to configure a VPN correctly on our setup page.
Myth 4: VPNs Significantly Slow Down Internet Speeds
Reality: High-quality VPNs have minimal impact on performance when properly configured.
VPNs introduce some overhead due to encryption and routing, but modern services mitigate this effectively. Key factors affecting VPN speed include:
- Encryption Overhead: Modern protocols like WireGuard are lightweight, and most devices handle encryption with negligible performance impact.
- Server Distance: Connecting to a geographically close server minimizes latency. Advanced VPNs use technologies like load balancing to optimize performance.
- Server Load: Overloaded servers can slow connections, but quality providers distribute users across multiple servers to maintain speed.
Double-VPN configurations, which route traffic through multiple servers, may reduce speeds due to increased latency but are only necessary for high-threat scenarios.
VPN Plan Comparison for Performance Needs
Selecting a VPN plan tailored to your performance and user requirements is crucial. Below is a comparison of available plans:
| Plan | Users | Devices | Price (Monthly) |
|---|---|---|---|
| Individual | 1 | 1 device | $3 |
| Family | 5 | 5 devices | $5 |
| Business | 10 | 10 devices | $7 |
All plans include: Dedicated IP, Port Forwarding, Unlimited Bandwidth, No-logs Policy, WireGuard & IKEv2.

Best Practices for VPN Deployment
To maximize VPN effectiveness, IT professionals should consider the following:
- Choose Reputable Providers: Opt for VPNs with audited no-logs policies and robust protocol support.
- Optimize Server Selection: Use servers close to your location to reduce latency.
- Monitor Server Load: Select servers with low user loads for better performance.
- Use Modern Protocols: Prefer WireGuard or IKEv2 for speed and security.
Conclusion
VPNs are indispensable for protecting online privacy, but they are not a cure-all for security. By understanding their strengths—hiding IP addresses, preventing ISP tracking, and securing public WiFi—and limitations, IT professionals can deploy VPNs effectively. Choosing a high-quality VPN service with modern protocols and no-logs policies ensures optimal privacy without sacrificing performance.
