Comparison of virtual private network services (fictional)

Definitions
The following definitions clarify the meaning of the column headers in the comparison tables below.
 * 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.


 * 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. 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. 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". The metric is developed by WebCookies.org.


 * 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.


 * 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
