A double VPN is a configuration that routes your internet traffic through two VPN servers in sequence, encrypting it twice, so that no single server in the chain has simultaneous access to both your real IP address and your destination. The first server receives your encrypted traffic, strips its own encryption layer, and forwards the … Read more
No, a VPN does not protect against all cyber threats. It operates at the network layer: it encrypts traffic in transit between your device and the VPN server and replaces your IP address. Threats that operate at any other layer are outside its scope by design, not by deficiency. Where a VPN’s protection stops depends … Read more
A VPN tunnel is an encrypted, encapsulated connection between your device and a VPN server, through which your internet traffic is routed. Your original data packet is wrapped inside a new outer packet addressed to the server; the inner payload is encrypted; and every intermediate node on the path sees only the outer header, not … Read more
Yes, VPNs are legal in most countries, including the United States, the entire European Union, the United Kingdom, Canada, and Australia. A small group of governments restricts VPN use to state-authorised services only; a handful have made most VPN use effectively off-limits. “Is a VPN legal?” is three separate questions packaged as one, and conflating … Read more
VPN port forwarding opens a numbered port on your VPN provider’s server and routes inbound traffic through the encrypted tunnel to your device, making it reachable from the internet despite sitting behind the VPN. By default, a VPN blocks all unsolicited inbound connections to your device. Port forwarding carves an exception into that firewall at … Read more
The Five Eyes, Nine Eyes, and Fourteen Eyes are three nested tiers of a Western signals intelligence network covering fourteen nations. Only the innermost tier rests on a formal written agreement: the UKUSA Agreement, signed on 5 March 1946. The Nine Eyes and Fourteen Eyes are informal extensions with no equivalent multilateral document. TL;DR The … Read more
A self-hosted VPN puts you in control of the server. You install the software, define the logging policy, and hold the cryptographic keys. What it does not give you is more privacy than a well-configured commercial provider. Two architectural distinctions determine almost everything: whether you host on hardware at home or on a rented server … Read more
RAM-only VPN servers wipe all data at every reboot. That is the claim, and on a powered-off server subjected to post-seizure forensic examination, it is accurate. The protection is real, it is enforced by hardware physics rather than policy, and it is independently verifiable in ways that a software-based no-log promise cannot match. A provider … Read more
Perfect forward secrecy (PFS) is the cryptographic property that protects past VPN sessions even if the server’s private key is obtained in the future. Session keys are derived from temporary key material generated fresh for each connection and permanently deleted after use; no persistent key can reach keys that no longer exist. What most accounts … Read more
AmneziaWG is a fork of WireGuard-Go that modifies the protocol’s packet structure to defeat deep packet inspection. DPI identifies and blocks VPN traffic by shape rather than content, without decrypting anything. WireGuard’s Handshake Initiation is always exactly 148 bytes, with a 32-bit type field whose first octet is 0x01 and three reserved zero bytes. Its … Read more
