HPN - Post Quantum VPN
Post-Quantum VPN. No longer reserved for the enterprise.
HPN is a next-generation VPN by HMSX Solutions that democratizes state-of-the-art security. Protect your infrastructure today against the threats of tomorrow using the post-quantum algorithms standardized by NIST in FIPS 203 and FIPS 204.
I'm Hugo, founder of HMSX Solutions. We spent the last 18 months building HPN because we couldn't ship a VPN to ourselves with a straight face anymore. Why post-quantum, why now ?: NSA's CNSA 2.0 (2022) and NIST's FIPS 203/204 (2024) make the threat model official: every byte you encrypt with X25519 today can be captured now and decrypted in 5–10 years when CRQCs land. For most products that's an academic problem. For a VPN — whose entire job is long-lived confidentiality of every packet you send — it's the only problem that matters.
What HPN actually is: - A hybrid X25519 + ML-KEM-768/1024 handshake, ML-DSA-65/87 server signatures, AES-256-GCM data plane (AES-NI hot path). I'd rather lose the marketing buzzword than have a researcher screenshot a fake one. - Self-hostable Linux server, Kill switch is on by default, DNS leaks closed including IPv6 RA-RDNSS on Free Box-style dual-stack setups. - Every claim above maps to specific files; happy to walk security researchers through it. - Three tiers: Free (10 sessions, full PQ crypto), Pro €39.99/yr (100 sessions, IPv6, priority support), Enterprise (unlimited + custom SLA). License enforcement is 100% server-side; clients are tier-agnostic, no "downgrade by patching the binary" attack.
What HPN is not: - A "we shipped ML-KEM" sticker on a WireGuard fork. The protocol is custom, the hybrid is real, the build pipeline is reproducible. - A consumer freemium thing funded by ads. We charge for Pro because building this right is full-time work for a small team. Zero third-party trackers, zero Google Fonts (self-hosted), zero analytics-as-a-service. The privacy posture is in `/privacy` and it's stickier than I've seen elsewhere, read it. - French-only. We're a French company but the product, site, docs, and support are EN + FR from day one.
What I'd love your feedback on 1. The pricing page: does FREE → PRO → ENTERPRISE read as honest or freemium-trappy? "10 sessions free" is a real number, not a teaser. 2. The security page: the comparison table vs WireGuard / OpenVPN / IPsec: confident-but-fair, or arrogant?
I'd love quiet-mode beta testers, especially on weird network topologies (corporate NAT, captive portals, IPv6-only).
The project is currently in beta, so there are bound to be some optimisation issues and security vulnerabilities, but we’re doing our best to improve it and make it as secure as possible !

Hey Product Hunt 👋
I'm Hugo, founder of HMSX Solutions. We spent the last 18 months
building HPN because we couldn't ship a VPN to ourselves with a
straight face anymore.
Why post-quantum, why now ?:
NSA's CNSA 2.0 (2022) and NIST's FIPS 203/204 (2024) make the threat
model official: every byte you encrypt with X25519 today can be
captured now and decrypted in 5–10 years when CRQCs land. For most
products that's an academic problem. For a VPN — whose entire job is long-lived confidentiality of every packet you send — it's the only problem that matters.

- Self-hostable Linux server, Kill switch is on by default, DNS leaks closed including IPv6 RA-RDNSS on Free Box-style dual-stack setups.
- Every claim above maps to specific files; happy to walk security researchers through it.
