What is a VPN and how does it work?

A VPN (Virtual Private Network) creates a secure connection between your device and a remote server. All your internet activity goes through this secure link, keeping your online actions private.

What are the benefits?

✅ Your internet service provider (ISP) can’t see which websites you visit.
✅ It changes your IP address, making it appear that you’re in another country.
✅ It secures your data on public Wi-Fi.
✅ It encrypts your data, making it harder for others to intercept.

Simple example:

Without a VPN: Your ISP knows you visited cryptvice.com and sees the site’s IP.
With a VPN: Your ISP only knows you connected to a VPN server. That’s all.

But here’s the catch:

Your VPN provider can see your traffic as well. Choosing the right one is important.

Curious about “what if I use VPN + Tor?”

VPN + Tor = hides your Tor use from your ISP
Tor + VPN = can bypass blocks on Tor
But be careful: if you set it up wrong, it might lower your privacy instead of boosting it.

Tor provides good anonymity. A VPN can be helpful in some situations (like when facing censorship), but it’s not always better.

What can your internet provider see when using a VPN?

When your VPN is on, your ISP can’t see:

✅ The websites you visit
✅ The apps you use
✅ Your online activities

All they know is that you are connected to a VPN server. Nothing else. However, the VPN can see everything you do because your data passes through their servers. That’s why it’s important to choose a reliable provider.

👉 What should you look for?
✅ A strict no-logs policy (and third-party audits)
✅ The country they operate from (data laws)
✅ Their privacy history (have they cooperated with authorities?)
✅ Transparency reports and legal cases

VPNs aren’t perfect. They handle your data, but your VPN also has access to it. If you can’t trust your provider, the problem hasn’t really changed.

In future posts, we’ll clarify what “no logs” means and how to identify trustworthy VPNs versus untrustworthy ones.

Not everyone needs a VPN

Despite what you hear, whether you need a VPN depends on your situation and usage.

When a VPN is useful:

✅ To protect yourself on public Wi-Fi
✅ To hide your IP address from websites and apps
✅ To access restricted content or websites
✅ If you live in a country with heavy surveillance

When it can cause problems:

⚠️ For banking or sensitive logins.
Many banks block VPN traffic or foreign IP addresses. Your account may get locked for “suspicious activity”. When doing financial transactions, turn off the VPN or use a local server to avoid issues.

A VPN doesn’t guarantee anonymity. It’s a tool for privacy, not a bulletproof shield.

What is VPN Split Tunneling and why is it important?

Split Tunneling allows you to select which apps or connections use the VPN and which do not.

This is helpful if, for example:

🏦 You want to browse securely but keep your banking app connected directly without the VPN.

Why?

Many banks block access from foreign IPs (like those from VPNs) for security reasons, which can lead to account locks or alerts.

With Split Tunneling, you can avoid these problems and maintain your privacy where it’s needed.

Remember: using a VPN doesn’t have to be “all or nothing.” You can adjust it to fit your needs and comfort level.

Understanding “No logs”: it doesn’t guarantee true privacy.

Many VPN services say they don’t track your activity, but can you really believe them?

Here’s the main point:

🔒 “No logs” policy: this means the provider claims not to keep data about you, but often there’s no way to confirm this.

🛠️ Regular technical checks and special hardware: some providers use servers built to ensure no data is stored (“wiped” hardware), with independent audits and round-the-clock monitoring to prove no logs are kept.

💳 Also: prefer VPNs that accept anonymous payments like Monero or gift cards. Stay away from those that require credit cards or personal ID.

⚙️ Tip: choose VPNs that utilize WireGuard or other modern protocols as they’re faster and safer than older options like PPTP or even OpenVPN.

Providers like Mullvad ve iVPN are known for these practices. Some also share transparency reports and have faced legal actions proving they have no data to provide. Always review their transparency reports and any legal matters for verification.

Why is this important? If a VPN keeps logs, they can track you, share your info with others, or harm your privacy. Not all “no logs” policies are the same: stay informed, ask questions, and seek proof.

Why are permissionless decentralized VPNs (dVPNs) often better than centralized VPNs?

Traditional VPNs depend on one provider that controls servers and data. This creates a weak point vulnerable to censorship, surveillance, or data leaks.

In contrast, permissionless dVPNs operate on distributed networks with no main controller. This means:

✅ Better resistance to blocks and censorship
✅ Lower chance of data collection or leaks
✅ Transparency and trust through blockchain and open source
✅ Real user control over data and connections

Though newer and facing challenges, they signify the future of online privacy.

Not all VPNs are the same.

ProtonVPN is a good option with fair transparency and security. However, it’s not completely private—some data logging and legal cooperation mean full anonymity isn’t assured.

Be cautious of VPNs that claim “total privacy” but have questionable practices:

❌ Many free VPNs track and sell your data.
❌ Some well-known apps have been found to log user activity even with “no logs” promises.
❌ Always avoid VPNs that lack clear transparency reports or independent audits.
🚫 Don’t trust free VPNs; if you aren’t paying, you might be the product.
✅ Services like Mullvad and iVPN offer verified no-logs policies and prioritize privacy.

The best way to protect yourself is to make informed decisions: check transparency reports, look for audit results, and research any legal issues involving your VPN.

Remember: a VPN can enhance privacy but won’t make you invisible. Choose carefully.

VPNs are powerful tools, but only when used right.

Don’t fall for marketing. Know your needs, choose your provider wisely, and combine tools for real privacy.
