A Virtual Private Network (VPN) is a powerful tool for enhancing online privacy and security, but its ability to protect against hackers is often misunderstood. While a VPN can mitigate specific types of cyberattacks, it is not a comprehensive defense against all hacking attempts. This article explores how VPNs safeguard users, the types of attacks they can prevent, and their limitations, providing IT professionals and advanced users with clear, actionable insights.
How a VPN Enhances Security
A VPN creates a secure, encrypted tunnel between your device and a VPN server, masking your IP address and protecting your data from interception. This functionality is particularly valuable on unsecured networks, such as public WiFi, where hackers often exploit vulnerabilities. Below are the primary mechanisms by which a VPN bolsters security:
- Data Encryption: A VPN encrypts all internet traffic, ensuring that ISPs, network administrators, or hackers cannot view your online activities or DNS queries.
- IP Address Masking: By replacing your device’s IP address with that of the VPN server, a VPN prevents attackers from targeting your device directly.

Types of Cyberattacks a VPN Can Prevent
VPNs are most effective against attacks that exploit unsecured networks or rely on identifying your IP address. Below are key threats a VPN can mitigate:
Man-in-the-Middle (MITM) Attacks
In an MITM attack, a hacker intercepts data between your device and a server or router, potentially stealing sensitive information or impersonating you. A VPN’s encrypted tunnel prevents hackers from accessing your data, rendering MITM attacks ineffective.
Evil Twin Hotspots
Hackers may set up fake WiFi hotspots (e.g., “Cafe_WiFi_Free” mimicking “Cafe_WiFi”) to trick users into connecting. Once connected, attackers can monitor unencrypted traffic. A VPN encrypts your data, ensuring that even if you connect to a malicious hotspot, your activities remain secure.
WiFi Sniffing
Using packet-sniffing tools, hackers can analyze data packets on unsecured WiFi networks to steal information or hijack sessions. A VPN’s encryption ensures that sniffed packets are unreadable, protecting your data and credentials.
DNS Spoofing
Hackers can manipulate unencrypted DNS queries to redirect you to malicious websites. A VPN encrypts DNS requests and routes them through secure servers, preventing tampering and ensuring you reach legitimate sites.
IP-Based Remote Attacks
Attackers may use your IP address to scan for open ports or launch Denial-of-Service (DoS) attacks. By hiding your real IP address, a VPN reduces the risk of such targeted attacks.
Choosing the Right VPN Plan
Selecting a VPN plan depends on your organization’s needs, such as the number of users or devices. The table below outlines 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. For more details, visit our Pricing page.
Limitations of VPNs Against Hacking
While VPNs are effective against specific threats, they cannot protect against all types of cyberattacks. IT professionals should be aware of the following limitations:
- Malware: VPNs do not block malware, such as spyware, rootkits, or Trojans. Dedicated antivirus software is essential for detecting and removing malicious programs.
- Software Vulnerabilities: VPNs cannot protect against exploits targeting outdated apps or operating systems. Regular updates and patches are critical to minimize risks.
- Human Error: VPNs offer no protection against phishing attacks, weak passwords, or social engineering. Users must employ strong passwords, enable two-factor authentication (2FA), and exercise caution with suspicious emails or downloads.
Complementary Security Measures
To build a robust defense against hackers, combine a VPN with the following practices:
- Antivirus Software: Deploy and regularly update antivirus solutions to detect and remove malware.
- System Updates: Keep operating systems, applications, and firmware updated to patch known vulnerabilities.
- User Education: Train users to recognize phishing attempts and use strong, unique passwords with 2FA.
- Secure DNS: Use a VPN with encrypted DNS resolution to prevent spoofing and ensure secure browsing.

Impact of HTTPS on VPN Necessity
Most modern websites use HTTPS, which encrypts data between your device and the website, reducing the risk of data interception on public WiFi. However, HTTPS does not conceal the websites you visit or protect against DNS spoofing, making a VPN valuable for comprehensive privacy and security.
Conclusion
A VPN is a critical tool for protecting against specific hacking threats, such as MITM attacks, WiFi sniffing, and DNS spoofing, particularly on unsecured public WiFi networks. However, it is not a complete solution. By combining a VPN with antivirus software, regular updates, and strong user authentication practices, IT professionals can significantly enhance their organization’s security posture. Select a trusted VPN provider with robust encryption and a no-logs policy to ensure maximum privacy.
