Virtual Private Networks (VPN) are no longer just specialized security tools; they have become essential for remote access in companies and a vital part of personal security toolkits—whether for traveling or protecting data at home from prying eyes.

When you browse the internet on a private network, your data is visible and traceable by your ISP (Internet Service Provider), advertisers, trackers, and malicious actors. A VPN utilizes Encryption to turn this readable data into an indecipherable string of characters.
Do VPNs Make You Anonymous Online?
It is almost impossible to be 100% anonymous online; as long as you are connected to an ISP, a data trail exists. However, a VPN makes it extremely difficult for anyone to accurately track your movements, location, and activity.
ISPs and Privacy: ISPs often collect and sell user data—a practice usually hidden in the "Privacy Policy." A VPN cuts this data flow, preventing the ISP from seeing your specific online activity. However, the ISP will still know how much data you use and when you are online.
Advertisers and Targeted Ads: Advertisers use your IP Address to monitor habits and serve targeted ads. A VPN masks your IP, making your traffic appear as if it is coming from a different location.
Browser Fingerprinting: Even without an IP, advertisers use "Browser Fingerprinting" (identifying you via browser version, screen size, etc.). While a VPN doesn't stop this entirely, it makes the process much harder by removing the associated IP data.
Do VPNs Protect Against Malware?
A VPN does not directly protect your device from malware. While some VPNs offer basic features like ad-blocking or malicious file detection, they are not a substitute for specialized antivirus software.
Today, it is common for VPN services to be part of an "All-in-one" security suite. For example:
Surfshark One: Combines antivirus with VPN services.
NordVPN: Includes "Threat Protection" in its high-tier plans.
Do You Really Need a VPN?
A VPN is a powerful shield for your online privacy, but it is not a "magic bullet." It fills a critical gap in your privacy toolkit by protecting data from ISPs and advertisers.
The Verdict: Because VPNs do not block all malware or stop complex cyberattacks, they should be used as part of an integrated security strategy that includes:
A strong Antivirus program.
A Password Manager.
Multi-Factor Authentication (MFA).
