A prominent US senator has formally requested that the National Security Agency provide public guidance on selecting appropriate virtual private networks for protecting communications from foreign adversaries. The request highlights growing uncertainty among Americans about which VPN services offer adequate protection, given the proliferation of options and technical complexity involved in assessing their capabilities.
VPNs encrypt internet traffic through remote servers, masking user IP addresses and preventing intermediate parties from viewing encrypted contents. However, significant limitations exist that can undermine their protections. Traffic typically becomes unencrypted once it reaches the destination server, potentially exposing it to rogue employees or attackers. Additionally, VPNs often fail to encrypt metadata such as timestamps, which nation-states can exploit for intelligence gathering purposes. These nuances mean generic recommendations to use VPNs lack sufficient detail for users to make informed decisions based on their specific threat levels.
Sen. Ron Wyden addressed specific technical questions in his letter to NSA Director Gen. Joshua Rudd, requesting clarification on several architectural approaches. These include whether single-hop VPNs—which route traffic through one server—adequately protect against foreign surveillance, versus multi-hop systems that pass data through multiple servers. The senator also asked whether features such as random delays and cryptographic padding provide meaningful protection against sophisticated attacks, and how specific services compare, including Apple Private Relay, Nym, and Tor.
Each service presents distinct advantages and drawbacks. Nym operates as an open-source tool using a decentralized network with volunteer-operated nodes and time-delay features. Apple Private Relay uses two commercial servers but remains limited to Safari on Apple devices. Tor routes traffic through three servers but relies on volunteer operators, some of whom could potentially be state-sponsored actors. The absence of trusted standardization in evaluating these options leaves ordinary users unable to determine which service matches their security needs.
Wyden requested that the NSA provide its recommendations by October 14, addressing how existing public guidance should be updated to help Americans make informed choices about VPN configuration and service selection.
