Rilian Raises $17.5M Seed to Build AI-Native Cybersecurity for Air-Gapped and Critical Infrastructure Environments

Seventeen and a half million reasons to pay attention, and not one of them is hype. Rilian just walked out of stealth like it had somewhere to be, and clearly it does. McLean, Virginia isn’t exactly known for loud entrances, but this one echoes a bit.

$17.5M later, Christian Schnedler (CEO and Co-founder), alongside Nick Pompeo (President and Co-founder) and Dan Fischer (Co-founder), aren’t pitching a “cybersecurity company.” That label’s been stretched thinner than airport WiFi. What they’ve built feels more like a control tower for chaos. AI-native, agentic, and aimed straight at environments where failure doesn’t trigger a support ticket, it triggers a briefing.

The $17.5M seed and seed extension round, led by 8VC, First In, and Tamarack Global, with participation from 8090 Industries, Liquid 2 Ventures, Perot Jain, and Protego Ventures, isn’t casual capital. That’s a table full of people who know exactly how ugly this problem gets. Air-gapped systems. Critical infrastructure. Sovereign networks. Places where adding “just one more tool” is how things quietly fall apart.

Rilian’s Caspian platform doesn’t join the stack. It conducts it. Less dashboard, more orchestra. Every security tool finally playing in time, with AI agents handling procurement, deployment, and operations like operators who don’t blink. No drama, no ego, just execution.

And then there’s the part most founders avoid because it slows the pitch down. Compliance. Sovereignty. The words that don’t trend but decide who actually gets deployed. Rilian doesn’t dance around that friction. It builds directly into it. That’s not marketing, that’s understanding where the real game is played.

The move here is disciplined. Don’t replace the stack, make it make sense. Don’t chase alerts, understand them. Act on them. Cut the noise, keep the signal. It’s the kind of approach that doesn’t look flashy until you realize it actually works where it counts.

There’s a lesson sitting right under this raise. Markets aren’t rewarding noise right now. They’re rewarding precision in places most companies can’t even access. If your product only lives comfortably in clean environments, you’ve already defined your ceiling.

Rilian isn’t trying to be everywhere. It’s choosing where it matters most, where stakes are measured in more than uptime. That focus carries weight, especially as AI-driven threats scale faster than the systems designed to contain them.
