[4/4]: We broke down the mechanics (TCP meltdown, DTLS fallback, mobility issues) in our new article.

If you are ready to see what a modern, WireGuard-based alternative looks like in practice, read the full guide here:

#Fortinet #WireGuard #SysAdmin #VPN #SelfHosted

[3/4]: These are transport-level behaviors, not bugs.

Defguard delivers the solution: we combine stateless WireGuard® transport with the Identity, MFA, and Access Control layers you need. No more “VPN is slow” tickets.

[2/4]: When "TCP over TCP" happens, admins typically see:

📉 Throughput collapse under even small packet loss.
🔄 Constant reconnects when users switch networks (Wi-Fi ↔ LTE).
💤 Full renegotiation after short connectivity glitches or sleep/wake mode.

[3/3] If you build critical infrastructure, don't rent your security. Own it.

Kudos to the co-authors for mapping the region! Read the full report: dealroom.co/uploaded/202...

[2/3] We believe that in tough times, the only infrastructure that truly never fails is the one you can fully control.

We were recognized for:

🔹 European Data Sovereignty
🔹 Privacy & Control
🔹 Trust through Open Source

Stop comparing features. Start comparing security approaches.

[6/7] THE TRANSPARENCY

[👁️‍🗨️] Legacy: Proprietary & Closed You’re forced to “trust” closed code and vendor claims.

[📖] Modern: Open-Source & Auditable Code is on GitHub. Pentests and SBOMs reports are public.

[5/7] THE ATTACK SURFACE

[🛡️] Legacy: Broad & Exposed Malware (like "COATHANGER" on FortiGate) can survive reboots & firmware upgrades, requiring a full reimage.

[🧱] Modern: Reduced to Minimum The Core (user data) is isolated from the public-facing Proxy. A breach is contained.

[4/7] THE ARCHITECTURE

[📦] Legacy: Monolithic “Black Box” A single proprietary OS runs everything. If one part fails, the whole system fails.

[☷] Modern: Microservice “Glass Box” Services are isolated. A proxy can fail, but the Core (and your connection) stays intact.

[3/7] SECURITY

[🔒💲] Legacy: MFA is a rigid and separated requiring extra tools or licenses (like FortiToken or FortiAuthenticator).

[🔐] Modern: Integrated MFA is enforced before the tunnel is established. A stolen key is useless without human verification.

[2/7] THE SPEED

[⌛] Legacy: Relies on heavy, stateful protocols (SSL VPN, IPsec) not built for modern speed.

[🚀] Modern: Built on lightweight, kernel-level WireGuard® optimized for performance.
