Free VPNs: Privacy and Security Risks You Should Know

Free VPNs may look like an easy way to improve privacy, but not all VPN services offer the same guarantees. A VPN routes traffic between your device and the internet; if the provider is not trustworthy, it can become a new risk point.

Risks of free VPNs

INCIBE explains in its article on free and paid VPNs that free services may involve privacy and security risks. Zero cost may be compensated through advertising, data collection, weak support, technical limitations or unclear practices.

• Activity logging: some VPNs may collect browsing or connection data.
• Advertising and tracking: some services monetise users through ads or profiling.
• Fake apps: some apps promoted as VPNs may include malware.
• Lower security: weak protocols, DNS leaks or insufficient encryption.
• Lack of transparency: unclear controller, jurisdiction or technical measures.

When a VPN makes sense

A VPN can be useful when connecting to public Wi-Fi, working remotely or accessing corporate resources. But it should be chosen carefully. INCIBE recommends trusted tools with a good reputation, proper configuration and secure protocols.

Checklist before installing a VPN

• Check who the provider is and where it is established.
• Read the privacy policy and logging practices.
• Avoid unknown apps outside official stores.
• Prefer secure protocols such as WireGuard, OpenVPN or IKEv2/IPsec.
• Keep the app updated and remove VPNs you no longer use.

Conclusion

A VPN does not guarantee absolute anonymity and does not replace other security measures. If the provider is not reliable, a free VPN may expose more data than it protects.
