VPN vs. "Filtershekan" — What's the Difference and Which Is Right for Iran?
In casual Persian conversation, "filtershekan" and "VPN" are often used interchangeably, but technically they are not the same thing. The difference matters for your security.
What is a VPN?
A VPN (Virtual Private Network) is an encrypted, secure tunnel between your phone/computer and a server in another country. All your internet traffic flows through that tunnel:
- ✅ Your traffic is fully encrypted
- ✅ Your ISP and government can't see what you're doing
- ✅ Your IP changes
- ✅ You access all sites (not just blocked ones) through that route
What is a "Filtershekan"?
"Filtershekan" is a Persian colloquial term for anything that bypasses censorship. That can include:
- Plain proxies (HTTP/SOCKS) — no encryption, just route changes
- Public DNS (like Google's 8.8.8.8) — only bypasses certain filters
- Sketchy free apps — typically sell your data
- Browser extensions — only route browser traffic
- And of course, a VPN is also a type of filtershekan
Key differences
| Feature | Reputable VPN | Free "filtershekan" |
|---|---|---|
| Encryption | ✅ Full | ❌ Often none |
| Speed | ✅ High | ❌ Low and unstable |
| Data privacy | ✅ Safe | ❌ Usually sold |
| HD streaming | ✅ Possible | ❌ Usually poor |
| Video calls | ✅ Stable | ❌ Choppy |
| Bypasses smart censorship | ✅ With Reality/XTLS | ❌ Detected |
| Support | ✅ Available | ❌ None |
Why are "free filtershekans" dangerous?
Free filtershekan apps you install on your phone typically do one of these:
- Sell your data to ad companies — even messages and passwords
- Install malware to steal banking info
- Turn your phone into a botnet node for cyberattacks
- Inject ads into your traffic

So which should I choose?
If you just want to open a single site and security doesn't matter, a DNS proxy is enough.
But if you want to:
- Do online banking
- Make video calls
- Send private messages
- Stream Netflix/HBO
- Connect your family in Iran
You need a reputable VPN with V2Ray protocol.
What is V2Ray?
V2Ray is an advanced protocol platform built for countries with smart censorship (like Iran and China). We explain it fully here.
Why did this confusion start?
The reason "filtershekan" and "VPN" became synonyms in Persian is historical: years ago, the first censorship-bypass tools in Iran were plain proxies, not real VPNs. People called all of them "filtershekan," and when VPNs arrived, the same name stuck. Today that merging is dangerous, because it makes users treat an insecure proxy app and an encrypted VPN as the same thing — when, security-wise, they are worlds apart.
Frequently Asked Questions
Every VPN is a filtershekan, but not every filtershekan is a VPN — right? Exactly. A VPN is a subset of filtershekans that adds full encryption and strong security. A plain proxy or modified DNS is also a filtershekan, but it is not a VPN.
Is a free filtershekan always bad? Not always, but telling safe from unsafe is hard for an average user, and the risk is high. A reputable VPN with a free trial is safer.
How do I know if my tool actually encrypts? If you only enter a "proxy address" and port with no TLS/certificate, it probably has no encryption. Modern VPNs (V2Ray/Reality) always run over TLS.
Summary
- VPN = a type of filtershekan, but with high security and speed
- Free filtershekan = usually unsafe and slow
- For daily and family use, always pick a reputable VPN
