What is a VPN and do I need one?
VPN stands for Virtual Private Network. Think of it as a private tunnel for your internet traffic — it encrypts everything you send and receive, making it much harder for others to spy on your activity. At home on your own network, a VPN is not usually necessary. Where a VPN really helps is on public Wi-Fi — hotels, coffee shops, airports. If you frequently use public Wi-Fi, a paid VPN from a reputable provider is worth considering. Be very cautious of free VPNs — many collect and sell your data, which defeats the purpose entirely. Reputable paid options in Canada include NordVPN, ExpressVPN, and Proton VPN.
What to do
- Decide if you need one — if you rarely use public Wi-Fi, you may not need a VPN at home.
- If you do want one, choose a reputable paid provider: NordVPN, ExpressVPN, or Proton VPN.
- Avoid free VPNs — they often collect and sell your personal data.
- Download the VPN app from the official App Store.
- Follow the setup instructions — usually just pressing a 'Connect' button.
- Turn it on when using public Wi-Fi and turn it off at home if desired.
The 3-Second Rule
If you use public Wi-Fi regularly, a paid VPN from a reputable provider is one of the best privacy investments you can make.
Important Warning
Free VPNs are almost always a bad deal — the product is you. Many free VPN providers sell your browsing data to advertisers. Pay for a VPN or use your mobile data instead.
