College students don't have to choose between privacy and eating. From Proton VPN's free unlimited tier to $0 self-hosted PiVPN and discounted commercial options under $3/mo, here are the cheapest ways to stay secure on campus wifi.
Campus wifi is convenient, but it's also monitored by your school's IT department, and public networks are a known risk for anyone logging in from a coffee shop or library1. Schools also block sites — streaming services, social media, gaming servers — and a VPN is the standard workaround3. The good news: you don't need to spend much, or anything at all, to get solid protection.
Here's the honest breakdown: free tiers cover the basics, self-hosted solutions cost $0 if you're willing to tinker, and commercial paid VPNs unlock firewall bypass, streaming, and support — many with student discounts that bring the price under $3/month1.

Proton VPN's free plan is the only major free VPN with unlimited data and no ads1. That alone makes it the top pick for students who need protection on campus wifi without spending a dime. The free tier does limit which servers you can connect to and doesn't support streaming, but for browsing, banking, and keeping your traffic encrypted on shared networks, it's genuinely excellent1.
If you want the paid features — more servers, streaming support, higher speeds — Proton offers a 75% student discount that brings the paid plan down to about $2.49/month2. PCMag named it their Editors' Choice for students1.
Verdict: Start here. If the free tier does what you need, you're done. If not, the student discount makes the paid upgrade one of the cheapest full-featured options.
PiVPN is a free, open-source installer that sets up a VPN server on a Raspberry Pi (or any Linux box) using WireGuard4. The software costs nothing. You'll need hardware — a Raspberry Pi runs about $35–$50 — but if you already have one or split the cost with roommates, your ongoing cost is literally $0.
The tradeoff is real: you need some technical comfort to set it up, and you're responsible for maintaining it. You also won't get the polished apps, streaming unblocks, or customer support that commercial VPNs provide. But for raw privacy on campus wifi, your own server is as private as it gets — no company logs, no subscription, no data limits.
Verdict: Best for CS students and tinkerers who want maximum control at zero recurring cost. Not for everyone, but unbeatable on price.
WireGuard is the open-source VPN protocol that PiVPN and many commercial VPNs now use under the hood. It's free, fast, and lightweight enough that it barely drains your laptop battery4. As a standalone pick, it's not a service — it's the technology. But if you're going the self-hosted route (or just want to understand what you're using), WireGuard is the modern standard.
Verdict: Not a product you "buy," but the backbone of the cheapest VPN approach. Worth knowing about if you're considering PiVPN or comparing protocol options.
Mullvad charges a flat €5/month (about $5.84) with no long-term commitment1. No yearly plan, no multi-year lock-in — you pay month to month and can cancel anytime. You also get an anonymous account number instead of an email-based login, which is about as private as commercial VPNs get1.
It's pricier than the discounted 2-year plans from NordVPN or Surfshark, but the flexibility is the point. If you only need a VPN for a semester or want to try a paid service without committing to 24 months, Mullvad is the most honest option. PCMag highlighted it as the best pick for avoiding subscription lock-in1.
Verdict: Best for students who want a full-featured paid VPN without being locked into a multi-year contract.
Security.org named NordVPN the #1 choice for bypassing school firewalls3. On a 2-year plan, it runs about $3.39/month with a student discount via Student Beans3. Save the Student lists it at £2.29/month on a 2-year plan with three free months, with a 74% student discount2.
NordVPN is the pick if your main goal is unblocking restricted content on campus — streaming, gaming, social media. It's packed with security features and strong encryption4, and the student discount makes it competitive with Surfshark on price. The catch is the 2-year commitment to get the best rate.
Verdict: Best for students whose priority is getting around school network restrictions, with a solid student discount to keep costs down.

The cheapest path depends on what you actually need:
Several VPNs offer student-specific discounts that significantly cut the cost1:
Always verify the current discount at checkout — promos change, but the student rates are consistently among the best prices available for these services.
You don't need to spend much to stay private on campus. Start with Proton VPN's free tier — if it covers your needs, you're set at $0. If you need more, the student discounts from Proton, NordVPN, and Surfshark all bring full-featured VPNs under $3.50/month. And if you're the DIY type, PiVPN on a Raspberry Pi gives you a private VPN server for the cost of the hardware alone.
The worst choice is using campus wifi with no protection at all. Even the free option is better than nothing.
