A reference you can navigate
vpn.com.de connects protocol references, provider documentation, comparison tables and practical network utilities. The site explains what a technology does, which configuration controls its coverage and where the supporting evidence can be checked. It provides information and tools; it does not operate the VPN services listed in the catalogue.
Start with the question you need to answer
Use Protocols for the connection mechanism and configuration checkpoints, Brands for official provider records, Compare for documented differences and Tools for address, subnet, DNS and configuration checks. A provider name on this site does not imply an endorsement, affiliation or independent hands-on test.
Languages and updates
The reference is available in English, German, Traditional Chinese, Simplified Chinese, Vietnamese and Russian. Protocol identifiers, brand names and version-specific limitations are preserved between languages. Page update dates identify an editorial revision; source-check dates identify when the linked evidence was reviewed. Neither date is a continuous guarantee of an external product’s current behavior.
