Tor vs. VPN: A Practical Guide to Anonymity

[Security]

Client anonymity​

• Tor via VPN - if you need to hide the fact that you're using Tor from your ISP
• VPN over Tor - if the site doesn't allow you to connect via Tor

---

A VPN provides privacy from your Internet Service Provider (ISP), but:

• You're simply transferring trust from your ISP to your VPN provider.
• Your VPN provider can see your traffic.

That is, the problem of trust remains, it’s just that the side changes.

---

The Tor network provides anonymity by routing your traffic through three random nodes around the world.

Benefits:

• decentralization
• distributed trust across different countries and jurisdictions

Risk:

• there is a low probability that all 3 nodes are controlled by an attacker, which could lead to deanonymization

---

Usage depends on two factors:

1. Client side (your country)
2. Server side (website or service)

---

If Tor is allowed:

• you → Tor → website

If Tor is blocked:

• You → VPN → Tor

If both Tor and VPN are blocked:

• the situation is extremely risky
• Possible bypass methods:
  
  • V2Ray
  • Cloak

It is important to use plausible deniability.

---

If it allows:

• Tor → website

If Tor blocks:

• Tor → VPN → website

If VPN is also blocking:

• You can try residential proxies.
• or refuse to use

---

If Tor is allowed:

• you → Tor → website
• You → Tor → VPN → Website

If Tor is blocked but VPN is allowed:

• You → VPN → Tor → Website
• You → VPN → Tor → VPN → Website

---

You can test different configurations in separate virtual machines (VMs).

Note:
There's no point in using Tor twice—once is enough.

---

Scheme:
You → VPN → Tor → Website

Pros:

• The provider doesn't see Tor
• When deanonymizing, only the VPN IP is visible

Cons:

• You need to trust your VPN provider

It is recommended to choose a VPN with:

• no-log policy
• the possibility of anonymous payment (for example, cryptocurrency)

---

Even through a VPN, Tor can be identified by patterns.

Solution:
use DAITA (Defense Against AI-guided Traffic Analysis).

This:

• masks traffic
• protects against packet sniffing

---

Problem:
Websites block Tor node IPs

Solution:
You → Tor → VPN → Website

Result:

• the provider sees Tor
• VPN doesn't know who you are
• The site thinks you're a regular VPN user.

Important:

• VPN must be purchased anonymously
• it is necessary to segment activity

---

(eg China, Iran)

Problem:

• VPN and Tor blocking
• criminal liability

---

Special nodes not included in public lists.

Used for:

• bypassing blockages
• hiding Tor usage

---

Additional layer of obfuscation:

• masks Tor traffic
• complicates detection

---

Risk:
Even if you are not detected now, it may be discovered later that you were using Tor.

---

In countries with strict censorship:

• Using Tor is associated with high risks
• consequences are possible even after some time

The author's position:
in such circumstances, it's better to avoid anonymity than to risk your security.
