What Is a VPN?
A VPN (Virtual Private Network) is a technology that creates a secure, encrypted tunnel between your device (phone, laptop, PC) and the internet.
It hides your real IP address and protects your online activities from hackers, internet service providers (ISP), and even public WiFi risks.
How Does a VPN Work?
When you connect to a VPN:
- Your device connects to a VPN server located somewhere else in the world.
- Your internet traffic gets encrypted (scrambled into unreadable code).
- Websites and apps only see the VPN server's IP address, not yours.
Why Do People Use VPNs?
1. Online Privacy & Security
A VPN keeps your internet activities hidden from:
- Hackers
- Public WiFi snoopers
- Your internet service provider (ISP)
This is especially useful in cafés, airports, malls, or any public network.
2. Access Geo-Restricted Content
Ever tried watching a show that’s “not available in your region”?
A VPN helps you appear like you’re browsing from another country.
Useful for:
- Streaming platforms (Netflix, Hulu)
- Games
- Websites blocked in certain regions
3. Bypass Internet Restrictions
Some networks (campus, office, or even country-level firewalls) block certain apps or websites.
With a VPN, you can access them like normal.
4. Safe Remote Work
Companies use VPNs so staff can access internal systems securely — this became common during WFH times.
5. Prevent Tracking & Targeted Ads
Without a VPN, websites and advertisers track your:
- Location
- Device
- Browsing habits
A VPN hides your identity so you’re less exposed to data collection.
When Should You Use a VPN?
- When using public Wi-Fi
- When working remotely
- When travelling (to access Malaysia content or banking safely)
- When watching geo-blocked content
- When you want privacy from advertisers or tracking
