[1/4]: Do you face a “slow and unstable SSL VPN” problem? 🐌

It’s likely not a configuration issue. Legacy SSL VPNs end up carrying TCP traffic inside a TLS/TCP tunnel, leading to the infamous "TCP Meltdown." 👇

[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...

Defguard listed in Dealroom's "Tough Tech" report as "Startup to Watch"!

The report maps mission-critical defence innovations on the NATO Eastern Flank.

It defines "Tough Tech" as technologies that "can't fail." 🧵 [1/3]

Stop comparing features. Start comparing security approaches.

Read our full 8-point strategic comparison to see why the "Glass Box" model is the future of secure access:

[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.

Do you actually know what happens inside your VPN when you connect?

You can’t secure what you can’t see — and most enterprise VPNs still run on legacy, closed designs.

This thread shows what you risk every time you trust a “Black Box.” 🧵 [1/7]
