According to the <a href="https://apps.apple.com/us/app/ipvanish-vpn-fast-secure/id763638165" target="_blank" rel="nofollow">App Store listing</a>, PQE applies to WireGuard on iOS. The notes don't mention OpenVPN or IKEv2, and there's no word yet on Android, Windows, macOS, or IPVanish's TV apps.</p><p>Several key questions remain, including which algorithm IPVanish is using, whether the setup is hybrid or fully post-quantum, whether it's switched on by default, and when other platforms will follow. </p><p>We've contacted IPVanish and will update this article when we hear back.</p><p>That said, the upgrade has been in the works for a while. Back in September 2025, IPVanish's Chief Commercial Officer Subbu Sthanu told <a href="https://www.technadu.com/exclusive-interview-subbu-sthanu-chief-commercial-officer-ipvanish/610481/" target="_blank" rel="nofollow">TechNadu</a> that post-quantum readiness was a major focus for its R&amp;D team, which was exploring hybrid encryption for both WireGuard and OpenVPN. </p><p>At the time, Sthanu said the team was "building custom implementations rather than relying on off-the-shelf patches."</p><p>The rollout also caps a busy few months for the provider, which recently <a href="https://www.techradar.com/vpn/vpn-services/ipvanish-clears-a-third-independent-audit-reinforcing-its-no-logs-credentials-for-the-second-year-in-a-row">passed its third independent no-logs audit</a> and continues to <a href="https://www.techradar.com/vpn/vpn-services/ipvanish-rolls-out-ram-only-server-filter-across-all-apps-to-make-it-easier-to-boost-your-privacy">expand its RAM-only server network</a>.</p><h2 id="hybrid-or-full-why-the-details-matter">Hybrid or full? Why the details matter</h2><p><a href="https://www.techradar.com/vpn/what-is-wireguard">WireGuard</a> isn't quantum-safe out of the box, as its key exchange relies on elliptic-curve cryptography. Providers usually fix this by running a separate post-quantum handshake, typically with the <a href="https://www.techradar.com/pro/vpn/post-quantum-encryption-standards-are-here-a-new-era-for-vpn-security-begins">NIST-standardized</a> ML-KEM algorithm, and feeding the result into WireGuard's pre-shared key slot.</p><p>Most VPNs, <a href="https://www.techradar.com/vpn/vpn-services/nordvpn-extends-post-quantum-encryption-protection-to-all-applications-heres-everything-we-know">including NordVPN</a>, take a hybrid approach that layers post-quantum protection on top of classical encryption, so a flaw in the newer algorithm wouldn't leave your data exposed.</p><p>Some providers are now pushing further. In October 2026, <a href="https://www.techradar.com/vpn/vpn-services/surfshark-claims-a-major-first-by-bringing-full-post-quantum-security-to-wireguard">Surfshark added ML-DSA authentication to WireGuard</a>, claiming full post-quantum coverage of encryption, key exchange, and authentication. Without quantum-resistant authentication, a future attacker could, in theory, impersonate a VPN server. <a href="https://www.techradar.com/vpn/vpn-privacy-security/post-quantum-encryption-is-not-the-end-nordvpn-aims-for-world-first-security-milestones-in-2026">NordVPN is also working on post-quantum authentication</a>. </p><p>Knowing where IPVanish sits on this spectrum will tell us how complete its protection really is.</p><a href="https://x.wayin.com/display/container/dc/efe848be-588a-4e20-8711-6e02de64b315/details"><figure class="van-image-figure inline-layout" data-bordeaux-image-check="" ><div class='image-full-width-wrapper'><div class='image-widthsetter' style="max-width:1200px;"><p class="vanilla-image-block" style="padding-top:26.17%;"><img id="Z7QHFc4GHoMhdps5XmntoC" name="LNT-masthead" alt="Leave No Trace logo" src="https://cdn.mos.cms.futurecdn.net/Z7QHFc4GHoMhdps5XmntoC-1920-80.png" mos="" align="middle" fullscreen="" width="1200" height="314" attribution="" endorsement="" class="inline" /></p></div></div><figcaption itemprop="caption description" class=" inline-layout"><span class="credit" itemprop="copyrightHolder">(Image credit: Future)</span></figcaption></figure></a><p><strong>NEW</strong>: <a href="https://x.wayin.com/display/container/dc/efe848be-588a-4e20-8711-6e02de64b315/details" target="_blank" rel="nofollow"><strong>Leave No Trace</strong></a> — A weekly newsletter on digital privacy and online surveillance.
