As mentioned above, Tor is vulnerable to timing attacks and other types of advanced compromises that require government-like resources. For that reason, a government with sufficient resources can deanonymize some Tor requests if they control the right internet service providers which is almost always true of the American government.

If you decide to access the Dark or the Deep web , do it in a safe way. Virtual private network VPN services are frequently marketed as a way to improve privacy or gain anonymity. In reality, VPN services can be hit-and-miss when it comes to privacy. Some are certainly better at protecting data than Tor, whereas others will compromise your privacy more than not using one at all.

VPNs are point-to-point tunnels. In that sense, they are similar to Tor. However, there are few ways this claim can be proven beyond a reasonable doubt. So if you do end up choosing a VPN for privacy, it's best to go with one that has had its no-logs policy tested in the wild due to some police investigation , or at least one that has had the infrastructure audited by a trustworthy, independent third-party.

The biggest advantages of VPNs over Tor include much better connection speeds for downloading videos and other large files. Also, with a VPN, you can choose the server your data is routed through, or at least the country in which that server is located. Read more: Tor over VPN. In most of the world, using Tor is perfectly legal. However, there are plenty of illegal activities that can be facilitated with Tor hidden services, so Tor usage may be seen as suspicious by many governments or internet service providers.

That said, you can use any other search engine you choose—but note that DuckDuckGo uses the least tracking of any major search engine. Additionally, there are a number of other ways to track users aside from IP addresses. Be sure not to reveal your identity in any other way, like signing into an account you use from another connection. Tor Browser includes a variety of tracking prevention features that help prevent unique browser and device characteristics from being used to fingerprint you across the web.

No matter what, vigilance is always necessary to protect your anonymity. Not reliably. Using Tor in China is significantly more complicated than in most other parts of the world; it generally requires tunneling traffic to another country and then using Tor over that connection.

If you already have a VPN that works for getting access to websites that are blocked in mainland China, you may be able to use Tor through that VPN, which can improve your privacy significantly. If you want to protect your privacy and anonymity as much as possible while browsing the web, Tor and the Tor Browser may be a good choice. Tor is a widely used and well-studied way to avoid surveillance and censorship from internet service providers and government agencies.

It also offers access to. Once you click connect, Tor may take a few minutes to find a set of relays to connect you through. But once you're in, you can use Tor just as you would any other browser. You'll also be prompted to review your Tor browser security settings. If you're aiming for maximum privacy, I'd advise leaving the settings on their default selections. If you start experiencing slower-than-normal speeds, you can nudge Tor into action by checking for a quicker connection path to the website you're trying to view.

In the top right corner of the Tor browser, click the three-line menu icon and select New Tor Circuit for this Site. The privacy-focused Brave browser also has an option to route traffic through Tor when inside a private window.

Because Tor is a volunteer-run network, speed can often be an issue. As your traffic moves from node to node, you're likely to notice more speed loss than you would, for instance, with most commercial virtual private networks. This becomes particularly noticeable if you try to watch streaming Netflix content over Tor or make voice-over-IP phone calls or video calls with an app like Zoom.

Tor technology isn't necessarily built to provide seamless audio-video experiences. Speaking of videos, there are also limits to the amount of privacy Tor can offer you if you enable certain browser media plugins like Flash. After the NSA surveillance revelations in , a new wave of users joined the service. Between 19 August and 27 August alone the number of people using Tor more than doubled to 2. It has since slipped back to just over 4 million.

The cloak of anonymity provided by Tor makes it an attractive and powerful for criminals. Tor can mask users' identities, but also host their websites via its "hidden services" capabilities, which mean sites can only be accessed by people on the Tor network. This is the so-called "dark web" element, and it's not unusual to see Tor pop up in stories about a range of criminal sites. In August, a service provider called Freedom Hosting went offline after the FBI sought the extradition of a year-old Irish man for charges relating to distributing and promoting child abuse material online.

Underground illegal-drugs marketplace Silk Road, which was shut down in early October , was another hidden site only accessible through Tor, as was another store called Black Market Reloaded which has been accused of facilitating illegal arms dealing as well as drug purchases.

Sites such as these are why Tor was recently described by British MP Julian Smith as "the black internet where child pornography, drug trafficking and arms trading take place" during a parliamentary debate on the intelligence and security services.

Smith went on to criticise the Guardian for reporting in detail on the claims that the NSA had been trying to crack Tor's security, suggesting that "many people in the police world feel will cause major issues in terms of picking up people engaged in organised crime".

In the past, the team behind Tor has responded to exactly this question, denying that the anonymity tool is an obstacle to police investigating criminal activities.
