Senator Ron Wyden has asked the National Security Agency to issue updated public recommendations on virtual private network configurations and best practices for Americans seeking protection from foreign surveillance threats.
Virtual private networks encrypt internet traffic through remote servers and mask user IP addresses from destination websites. However, VPNs have significant limitations that can reduce their effectiveness. Once encrypted traffic reaches a VPN server, it becomes decrypted and vulnerable to interception by compromised employees or attackers. Additionally, VPNs do not encrypt metadata such as timestamps, which nation-states can use to build intelligence profiles. The proliferation of VPN options—including single-hop services, multi-hop architectures, open-source clients, and commercial offerings—has created confusion among users trying to select appropriate tools for their security needs.
Wyden’s letter to NSA Director General Joshua Rudd outlined several specific technical questions for consideration. These include whether standard single-hop commercial VPNs adequately protect sensitive communications, whether multi-hop services such as Apple Private Relay, Tor, or Nym offer superior protection, and what technical features including random delays and cryptographic padding are necessary to defend against sophisticated surveillance. The letter specifically addresses three services: Nym, an open-source VPN using a decentralized mixnet architecture; Apple Private Relay, which routes traffic through two servers with one operated by Apple; and Tor, which encrypts traffic through three servers before delivery.
Each service presents distinct advantages and drawbacks. Tor and Nym rely on volunteer-operated servers, some of which may be controlled by nation-state actors. Apple Private Relay is limited to Safari on Apple devices and depends on content delivery networks that some users question. A Congressional Research Service memo reviewing available options provides no criteria for evaluation, leaving users unable to make informed decisions. According to network security experts, the lack of trustworthy standardization makes it difficult for ordinary users to assess their actual needs and select appropriate tools.
Wyden requested that the NSA provide its recommendations no later than October 14.
