Key Takeaways:
- VPNs can protect against hackers, but can’t prevent all cyber threats.
- They’re essential for public Wi-Fi security because they encrypt data and hide your IP address.
- VPNs work best when combined with antivirus software and strong passwords.
A VPN, or Virtual Private Network, acts like a secure tunnel for your internet traffic. It encrypts your data, scrambling it so cybercriminals can’t see what information you’re sending and receiving. This encryption makes it extremely difficult for anyone to steal your personal information or infect your device with malware.
Does a VPN protect you from hackers?
Yes, VPNs protect users from hackers. But they are not a complete solution.
They hide users’ real IP addresses and can prevent various types of cyber attacks, including DDoS attacks, Man-in-the-Middle attacks, malware infections, session hijacking, and phishing attempts.
However, VPNs have limitations, such as their inability to protect against malware and phishing attacks that have already compromised a device and human errors.
Pro tip: While VPNs provide significant protection, you should always combine them with other cybersecurity measures for comprehensive safety, such as using antivirus software and strong passwords.
How can a VPN help to prevent hackers from accessing your data?
VPNs offer encryption and other security features that make it difficult for malicious actors to intercept or access users’ data. This is because its technology creates an encrypted connection over the internet between your device and a remote server operated by the VPN service provider.
Here are the main ways that a VPN can protect your data:
Data encryption
When you use a VPN, your information gets scrambled into a “secret code.” This process is called encryption. Even if a hacker manages to grab your data, it will be unreadable and useless to them. This is especially important when you’re using public Wi-Fi at a coffee shop or airport, as these networks are often easy targets for cybercriminals.
IP address masking
Every device connected to the internet has a unique IP address, which is like your online home address. A VPN hides your real IP address and replaces it with the IP address of the VPN server. This makes it much harder for threat actors to pinpoint your exact location or target your specific device.
By encrypting your data and hiding your IP address, a VPN makes it much more difficult for attackers to:
- Target your device: By masking your IP, cybercriminals struggle to find and attack your specific computer or phone.
- “Listen in” on public Wi-Fi: A VPN acts like a shield, making your connection secure even on unsafe networks.
- Launch specific attacks, such as Man-in-the-Middle (MITM), DDoS attacks (distributed denial of service), and session hijacking.
Ad blockers and additional security features
Some paid VPN providers offer ad blockers and other security features that can help prevent malware infections and phishing attempts, further enhancing your protection against hackers.

What are the limitations of a VPN?
While VPNs are useful privacy tools, they should be combined with other security practices like keeping software updated, using antivirus software, and enabling two-factor authentication where possible.
| What VPNs Protect Against | What VPNs Cannot Protect Against |
|---|---|
| Data interception on public Wi-Fi | Phishing emails you click on |
| IP address tracking & location exposure | Malware already installed on your device |
| Man-in-the-Middle (MITM) attacks | Weak or reused passwords |
| DDoS attacks targeting your IP | Social engineering scams |
| Session hijacking | Human error (visiting malicious sites) |
| ISP tracking of your browsing activity | Viruses from downloaded files |
Here are the main cybersecurity threats that VPNs are too limited to provide any significant protection against:
Inability to prevent malware
VPNs primarily focus on encrypting data and hiding IP addresses, but they do not provide comprehensive protection against malware.
While some VPNs may include basic ad blockers or malware protection features, they are not as robust as dedicated antivirus software.
Vulnerability to social engineering
VPNs may block access to known malicious websites, but they cannot prevent users from falling victim to social engineering techniques, including phishing attacks, and providing personal information to fraudulent sites or emails. Your internet traffic will be encrypted, but it does not prevent malware or viruses from infecting your device if you accidentally download them or visit malicious websites.
Dependence on human behavior
VPNs rely on users to enable and configure them correctly. If users forget to activate their VPN or inadvertently disable it, they may expose themselves to cyber threats.
Additionally, human error, such as using weak passwords or falling for social engineering tactics, can undermine the effectiveness of VPN protection.
Important: If you do fall victim to a hacker attack, you can contact Proven Data experts for malware and ransomware removal and to restore any lost or corrupted data.
Frequently Asked Questions
Can you be hacked while using a VPN?
Technically, yes, you can be hacked while using a VPN, but it’s much less likely. A good VPN encrypts your data, making it very difficult to steal. However, VPNs have limitations, such as their inability to protect against malware and phishing attacks that have already compromised a device and human errors.
Pro tip: While VPNs provide significant protection against hackers, users should also employ additional cybersecurity measures for comprehensive security.
How do VPNs hide IP addresses?
When you connect to the internet without a VPN, your device directly communicates with websites and online services. In this process, your actual IP address is visible to them.
When you use a VPN, your device first connects to a special VPN server operated by your VPN provider. All your internet traffic then travels through this secure, encrypted tunnel to the VPN server. From the VPN server, your traffic then goes out to the internet (websites, apps, etc.).
Because your traffic appears to come from the VPN server’s IP address, your real IP address remains hidden. It’s like sending a letter through a post office box instead of directly from your home address.
Does VPN protect against Man-in-the-Middle attacks?
Yes, VPN can protect against Man-in-the-Middle (MITM) attacks. Thanks to the encryption, attackers are prevented from reading or tampering with your information. This is why a VPN is essential for using public Wi-Fi securely.
Public Wi-Fi: With vs Without VPN Protection
See the dramatic difference a VPN makes for your security
- Data sent in plain text
- Real IP address visible
- Vulnerable to MITM attacks
- No encryption protection
- Easy target for hackers
- Military-grade encryption
- IP address masked
- Protected from MITM attacks
- Secure encrypted tunnel
- Invisible to hackers
Can Private Browse replace a VPN?
No, private browsing cannot replace a VPN.
Private browsing, also known as Incognito Mode in Google Chrome browser or Private Browsing on Safari, only keeps your local activity private on your device. It ensures other users on the same computer won’t see your browsing history or cookies.
What Private Browsing Doesn’t Do:
- It doesn’t hide your IP address. Your location is still visible to websites and your internet provider.
- It doesn’t encrypt your data. Your internet traffic is not scrambled, leaving it vulnerable to hackers.
- It offers no extra data security against outside threats.
