Fexyn VPN vs Proton VPN

Overview

Proton VPN comes from the same team as Proton Mail — the encrypted-email service that built its reputation by hosting under Swiss jurisdiction and refusing to compromise on cryptography. Proton VPN inherits that positioning. Open-source apps across every platform. Independent audits by Securitum and SEC Consult. Secure Core multi-hop routing through privacy-friendly jurisdictions. A real free tier (rare among audit-credible VPNs). Of all the mainstream VPNs, Proton has the strongest claim to be the privacy gold standard.

Fexyn is a younger company — Wyoming LLC, currently in early-access Beta. Smaller network, no audit yet, no free tier. What Fexyn brings is a different protocol stack (VLESS Reality vs Proton's Stealth), kernel-level kill switch on Windows, regional pricing across 192 countries, and 24-hour short-lived certificates from Vault PKI. Different bets, both defensible.

At a glance

Protocol support & censorship resistance

Both ship WireGuard and OpenVPN. The interesting comparison is on stealth.

Proton's Stealth protocol wraps OpenVPN traffic in TLS-shaped padding. The intent is to make VPN traffic look like ordinary HTTPS. The catch is that the TLS handshake is synthesised, not real — the padding distribution, timing, and cipher selection are statistically distinguishable from a real browser handshake to a real public site. Modern DPI in Iran, Russia, and increasingly Turkey can flag it.

Fexyn Stealth (VLESS Reality / XRay) takes the opposite approach. The TLS handshake is real — to a real public website like microsoft.com, with the actual certificate that site serves. VPN data is carried inside the established session. To DPI watching the wire, the traffic is structurally indistinguishable from a real visit to that site. This is the meaningful technical difference for users in heavily-filtered countries.

Security & privacy

This is where Proton has earned its reputation. Open- source apps across every platform. Multiple independent audits. Swiss jurisdiction with strong privacy law. Secure Core multi-hop for users who want their entry and exit nodes in different jurisdictions. A clean track record. They're arguably the most audit-credible mainstream VPN.

Fexyn is closed-source today. There's no audit yet. Wyoming jurisdiction is defensible (strong First Amendment, warrant requirements) but it's not Switzerland.

Where Fexyn closes part of the gap is the certificate architecture. 24-hour short-lived certs from Vault PKI mean a leaked credential expires in hours, not months. Proton uses standard long-lived certs. For high-risk threat models — laptop seizure, border crossings — Fexyn's PKI is meaningfully better.

Both no-logs claims are precise. Proton's has been audited; Fexyn's hasn't. See the[no-logs policy](/no-logs-policy) for Fexyn's exact wording including the open admission that we haven't completed a third-party audit.

Speed

Both are fast on WireGuard. Proton's network is larger and the WireGuard implementation is mature. In regions where Proton has a nearby server and Fexyn doesn't, Proton will likely feel snappier.

On stealth modes, the comparison reverses. Proton Stealth adds throughput overhead and gets throttled by aggressive DPI. Fexyn Stealth uses the same TLS 1.3 transport whether the network is filtered or not, so throughput stays consistent.

Pricing

Proton offers a free tier — limited to a few server locations and lower speeds, but real and audited. For users who can't pay anything, this is meaningful and rare among trustworthy VPNs.

Proton VPN Plus is around $9.99/mo monthly, similar to Fexyn's Tier 1 monthly price. For longer commitments, Proton Plus drops to about $4.99/mo on a 2-year deal.

Fexyn uses regional pricing. In Tier 4 markets (Turkey, Russia, Pakistan, Indonesia, Argentina), the individual plan is $2.99/mo — substantially cheaper than Proton's flat global rate. In Tier 3 markets it's $3.99. For users in those regions, Fexyn is the cheaper paid option.

Verdict

Proton VPN is the right pick if any of these apply:

• Privacy reputation and audit history are your primary criteria. Proton has the strongest mainstream claim.
• You need a credible free tier.
• You want open-source clients you can build from source.
• You want Swiss jurisdiction specifically.
• You need multi-hop routing through different jurisdictions (Secure Core).
• You need broader platform support today (Proton ships native apps everywhere; Fexyn is Windows-first in Beta).

Fexyn is the right pick if any of these apply:

• You're in a country with active DPI filtering. VLESS Reality is structurally stronger than Proton Stealth against modern censorship.
• You're in a Tier 3 / Tier 4 market and the price difference matters.
• You care about short-lived credentials for threat models involving device seizure.

Be honest with yourself about which set you're in. For most US/EU users with no specific censorship concern, Proton VPN is the safer recommendation. For users in censored countries, Fexyn Stealth is the technical edge.
