A virtual private network (VPN) service provides a proxy server to help users bypass Internet censorship such as geoblocking and users who want to protect their communications against data profiling or MitM attacks on hostile networks.

A wide variety of entities provide "VPNs" for several purposes. But depending on the provider and the application, they do not always create a true private network. Instead, many providers simply provide an Internet proxy that uses VPN technologies such as OpenVPN or WireGuard. Commercial VPN services are often used by those wishing to disguise or obfuscate their physical location or IP address, typically as a means to evade Internet censorship or geo-blocking.

Providers often market VPN services as privacy-enhancing, citing security features, such as encryption, from the underlying VPN technology. However, users must consider that when the transmitted content is not encrypted before entering the proxy, that content is visible at the receiving endpoint (usually the VPN service provider's site) regardless of whether the VPN tunnel itself is encrypted for the inter-node transport. The only secure VPN is where the participants have oversight at both ends of the entire data path or when the content is encrypted before it enters the tunnel.

On the client side, configurations intended to use VPN services as proxies are not conventional VPN configurations. However, they do typically utilize the operating system's VPN interfaces to capture the user's data to send to the proxy. This includes virtual network adapters on computer OSes and specialized "VPN" interfaces on mobile operating systems. A less common alternative is to provide a SOCKS proxy interface.

In computer magazines, VPN services are typically judged on connection speeds; privacy protection, including privacy at signup and grade of encryption; server count and locations; interface usability; and cost.[1][2][3][4] In order to determine the degree of privacy and anonymity, various computer magazines, such as PC World and PC Magazine, also take the provider's own guarantees and its reputation among news items into consideration.[1][2]

Criticism and limitations

Users are commonly exposed to misinformation on the VPN services market, which makes it difficult for them to discern fact from false claims in advertisements.[5] According to Consumer Reports, VPN service providers have poor privacy and security practices and also make hyperbolic claims.[6] The New York Times has advised users to reconsider whether a VPN service is worth their money.[7] VPN services are not sufficient for protection against browser fingerprinting.[8]

Common misconceptions

Legality

Further information: VPN blocking

In March 2018, the use of unapproved VPN services was banned in China, as they can be used to circumvent the Great Firewall.[12] Operators received prison sentences and were penalized with fines.[13][14][15][16] Russia banned various VPN service providers in 2021.[17]

Comparison of commercial virtual private network services

Privacy

PC Magazine recommends that users consider choosing a provider based in a country with no data retention laws because that makes it easier for the service to keep a promise of no logging.[18] PC Magazine and TechRadar also suggest that users read the provider's logging policy before signing up for the service,[18][3] because some providers collect information about their customers' VPN usage.[19][20] PC World recommends that users avoid free services as a rule of thumb and said free services either sell their users' browsing data in aggregated form to researchers and marketers, or only offer a minimal amount of data transfer per month.[19]

Notes

  1. ^ As claimed by provider unless otherwise noted.
  2. ^ a b There is no mention of Avira's VPN logging policy in their privacy policy. However, it is stated in an FAQ section that neither traffic nor IP addresses are logged on their VPN service.[21] It is also stated that bandwidth is logged.[21] When visiting Avira's website, the visitor's IP address is logged by both Google Analytics and the CrazyEgg tool.[22]
  3. ^ Hotspot Shield claims to collect "anonymous, aggregate data about which websites you visit and which apps you use."[32]
  4. ^ "We DO NOT keep any record of your browsing activities, connection logs, records of the VPN IPs assigned to you, your original IPs, your connection time, the history of your browsing, the sites you visited, your outgoing traffic, the content or data you accessed, or the DNS queries generated by you."[57] However, in 2017, PureVPN provided connection logs including IP addresses to the FBI for use in a criminal investigation.[58]
  5. ^ Name and e-mail is required for every payment method.[59]

Definitions

The following definitions clarify the meaning of some of the column headers in the comparison tables above.

Anonymous payment method
Whether the service offers at least one payment method that does not require personal information. Even if a service accepts a cryptocurrency like bitcoin, it might still require that the customer hands over personally identifiable information (PII) like their full name and address.
Bandwidth
Whether the users' bandwidth is logged while using the service, according to the service's privacy policy.
Diskless
Whether the service's server hardware is connected to hard drives, according to the service provider. If the servers are diskless, the service provider should be unable to log any usage data.
First-party DNS servers
Whether the service provides its own domain name system (DNS) servers.
Kill switch
Whether the service has the ability to immediately sever your connection to the Internet in the event that the VPN connection fails. This prevents a user IP address leak.[150]
Logging
Whether the service stores information about their users' connection or activity on the network, according to the service's privacy policy or terms of service. If logging isn't mentioned in those sections but denied somewhere else on the website, the particular table cell will be marked as "No" in yellow and include an explanatory note.
Privacy Impact Score
An indicator of a website's usage of potentially privacy intrusive technologies such as third-party or permanent cookies, canvas trackers etc.[151] The score can be in the range from 0 to 100, where 0 is minimal privacy impact (best) and 100 is the biggest privacy impact (worst) relative to other web sites.[151] The score also has a simplified letter and colour presentation from A to F where A is "No cookies" and F is "Score above three standard deviations from the average".[151] The metric is developed by WebCookies.org.[151]
Obfuscation
Whether the service provides a method of obfuscating the VPN traffic so that it's not as easily detected and blocked by national governments or corporations.[152][153]
Offers WireGuard
Whether the service provider offers the WireGuard tunneling protocol.
SSL rating
The service's website's overall SSL server rating according to Qualys SSL Labs' SSL Server Test tool.
Supports Obfsproxy
Whether the service has an implementation of the Tor subproject Obfsproxy.[152][153]
