Targeting integrated defense and security AI startup Lilium... raises $17.5 million in seed funding

Startup Rilian, which develops “AI-based Security Integration” tools for the defense and national security sectors, has raised $17.5 million in seed funding. In Korean won, this amounts to approximately 25.85 billion KRW.

The round was led by 8VC, Tamarack Global, and First In, with participation from defense technology-focused investment firms such as 8090 Industries, Liquid 2 Ventures, and Protégé Ventures. Rilian plans to build a “bridge” connecting the latest artificial intelligence technologies with tightly regulated defense and military systems.

Technology Delays and Limitations of Defense Security Infrastructure

The core issue the company aims to address is “technology delay.” Amid the rapid evolution of electronic warfare and cyberattacks, the U.S. and its allies are overwhelmed by massive alerts and data—so-called “noise.” The company explains that the problem is not a lack of security tools themselves, but the “execution gap”—the years required to introduce, verify, and deploy these tools in practice.

Especially in the defense sector, closed and highly regulated infrastructures such as air-gapped environments or sovereign clouds are often used. This results in new security systems being implemented on-site at a much slower pace than in the civilian sector. Additionally, multiple security solutions operate in silos, and a shortage of operational personnel leads to inefficient responses, which has been a longstanding criticism.

Caspian Platform and Application Strategy

Rilian’s flagship product is the AI-native security orchestration platform “Caspian.” This platform functions as a command-level system operating across the entire security stack, designed so that AI agents automatically perform threat detection, response, and target identification tasks, replacing manual monitoring of dozens of dashboards.

The company states that it particularly focuses on sovereign and air-gapped environment deployments. Caspian’s automated deployment engine aims to shorten update cycles from several weeks to just a few days, even in highly regulated environments. Its strategy also includes reflecting the institutional knowledge of skilled cybersecurity personnel into the system to reduce onboarding time for new staff.

Rilian targets the U.S. and allied countries’ markets as its primary focus and has already signed large contracts with the UAE Cybersecurity Council. The agency has introduced Caspian to automate and integrate security processes across multiple operational technology environments, with AI agents responding to security threats.

Market Outlook and Significance

The company believes the market potential is enormous. According to Rilian, global government-related spending is expected to exceed $70 billion annually around 2030. In Korean won, approximately 103.41 trillion KRW. The company emphasizes that achieving “zero trust” architecture within core IT infrastructure urgently requires a “connective organization” capable of linking various security systems.

Co-founder and CEO Christian Schnedler stated, “Security should be viewed as an engineering problem, not a manpower issue,” and “the goal is to reduce procurement delays and personnel shortages that hinder defense technology innovation.”

Rilian’s successful funding round indicates that beyond simple security products, “AI automation” and “integrated operations” are becoming increasingly important in the defense field. This is because the faster threats evolve, the more defense systems need to rely not only on human judgment but also on machine-level processing speeds.
