Incognito mode, a VPN, and Tor are the three most-mentioned privacy tools — and the three most-confused. They are often lumped together, but they solve completely different problems. This guide separates them clearly: what each one hides, what it does not, and which you actually need.
The one-line summary
- Incognito hides your activity from other people using your device.
- A VPN hides your traffic from your ISP and network.
- Tor hides who you are from the websites you visit.
They are not interchangeable, and in most cases you do not need all three.
Incognito mode: local privacy only
Private browsing stops the browser from saving history, cookies, and form data on the device. That is its entire job.
It does not hide you from: websites, your ISP, your employer, or trackers. It also does not make you anonymous. See Incognito Mode Myths for the full breakdown.
Best for: a shared computer, a borrowed device, or a session you want to keep out of local history.
A VPN: hiding from your ISP and network
A VPN routes your internet traffic through an encrypted tunnel to a server run by the VPN provider. From your ISP's perspective, it only sees "this device is connected to a VPN" — it cannot see which domains you visit or what you send.
What a VPN hides: the domains you visit and the content of your traffic, from your ISP, your network, and anyone on public Wi-Fi.
What a VPN does not hide: your identity from the websites you visit (they still see your VPN's IP address and your behavior), and your accounts and logins (a site you log into still knows who you are). A VPN also does not stop cookies or browser fingerprinting. And critically: the VPN provider sees everything your ISP would have seen. You are moving trust, not removing it.
Best for: public Wi-Fi, hiding your browsing from your ISP, and accessing content restricted by region.
Tor: anonymity from the websites you visit
Tor routes your traffic through three relay servers run by volunteers, encrypting it at each step. No single relay knows both where you are and what you visit. The Tor Browser comes with privacy defaults that minimize fingerprinting.
What Tor hides: who you are and where you are, from the websites you visit. It is the closest mainstream tool to real anonymity.
What Tor does not hide: it is slow, some sites block Tor traffic, and your own behavior (logins, personal details you type) still identifies you. If you log into your real accounts through Tor, you are not anonymous.
Best for: strong anonymity, bypassing censorship, and research where your identity genuinely matters.
The comparison table
| Incognito | VPN | Tor | |
|---|---|---|---|
| Hides from your ISP | No | Yes | Yes (relays) |
| Hides from websites | No | Partially (hides IP) | Yes (strong) |
| Hides from people using your device | Yes | No | No |
| Blocks trackers/cookies | No | No | Partially |
| Hides your logins | No | No | No |
| Speed | Normal | Slight reduction | Slow |
| Trust model | None needed | Trust the VPN provider | Trust the Tor network |
Which do you actually need?
- You share a computer: use incognito.
- You use public Wi-Fi often: use a VPN.
- You want your ISP to see less: use a VPN.
- You need strong anonymity: use Tor (and use it consistently).
- You are worried about ads following you: none of the three fix this — use browser privacy settings and privacy extensions.
The honest bottom line
No tool makes you fully invisible, and all three have limits. A VPN moves trust to the provider; Tor is slow and not immune to mistakes; incognito only cleans up the local device. The practical setup for most people is: incognito for shared devices, a reputable VPN for public networks, and the browser privacy settings in the browser privacy guide for day-to-day tracking. Tor is for the cases where anonymity genuinely matters.
Quick answers
Is a VPN better than incognito? They do different things. A VPN hides your traffic from your ISP and network; incognito keeps your activity out of the device's local history. Most people benefit from a VPN far more than from incognito.
Does Tor make me completely anonymous? No. Tor hides your IP and location from websites, but logging into your real accounts or revealing personal details defeats it. It is the strongest mainstream tool, not a guarantee.
Do I need all three? Rarely. Choose based on your threat: shared device (incognito), public Wi-Fi or ISP privacy (VPN), strong anonymity (Tor).
Does a VPN block ads and trackers? No. A VPN does not stop cookies, fingerprinting, or ads. Use browser privacy settings and extensions for that.
