Liberty Global Bets on Offensive AI in Cybersecurity Arms Race

DENVER and LONDON – May 06, 2026 – By Brenda Thompson

In a significant move that underscores the escalating role of artificial intelligence in digital defense, Liberty Global Tech Ventures has announced a strategic investment in XBOW, an AI-driven offensive security company. The investment is part of a funding round exceeding $150 million, placing the telecommunications giant alongside a formidable syndicate of technology leaders including DFJ Growth, Northzone, NVIDIA, Samsung, and Accenture.

The investment backs XBOW, a fast-scaling firm founded in 2024, which is pioneering a new category of autonomous security tools. This move signals a crucial acknowledgment from major industry players: in the new age of AI-powered cyberattacks, the old models of reactive defense are no longer sufficient.

The New Frontline: AI vs. AI in Cybersecurity

The digital landscape is witnessing an accelerating arms race, with both cybercriminals and security professionals wielding increasingly sophisticated AI tools. As threat actors leverage AI to automate attacks and discover vulnerabilities at an unprecedented scale, enterprises are scrambling for a defense that can keep pace. This is the challenge XBOW was created to address.

XBOW’s platform is built on a philosophy of “autonomous offense.” Instead of waiting for an attack, the system proactively and continuously tests a company's software and networks from an attacker's perspective. Using advanced AI reasoning, it autonomously maps application environments, probes for weaknesses, and attempts to execute multi-step exploitation paths, mimicking the Tactics, Techniques, and Procedures (TTPs) of advanced adversaries.

This proactive stance is critical, according to Bobbie Maltiel, Partner at Liberty Tech Ventures. “In an era where AI allows threat actors to weaponize vulnerabilities at machine speed, the only viable defense is a proactive offense,” Maltiel stated in the announcement. Every potential vulnerability XBOW finds is validated through real exploitation, providing security teams with reproducible proof of risk and eliminating the “scanner noise” and false positives that plague traditional security tools.

Beyond Telecom: Liberty Global's AI-Powered Future

This investment is more than just a financial stake in a promising startup; it represents a key pillar in Liberty Global's broader strategy to diversify and evolve beyond its traditional telecommunications core. Through its Liberty Growth platform and the Tech Ventures arm, the company is aggressively building a portfolio of what it calls “category-defining AI and technology businesses.”

With a portfolio already valued at $3.4 billion across approximately 70 companies, the investment in XBOW is the latest in a series of high-profile AI bets. It follows strategic investments in ElevenLabs, a voice AI and audio-AI platform, and Legora, a legal AI company that has seen meteoric growth. These moves illustrate a deliberate pivot towards becoming a key enabler and investor in the foundational technologies shaping the future economy.

Cybersecurity is a natural and critical focus for this strategy. The synergy is clear: Liberty Global, which manages vast broadband, video, and mobile networks serving approximately 80 million connections, is not just an investor but also a customer of XBOW. This provides XBOW with a complex, real-world environment to prove its technology at scale, while giving Liberty Global a front-line defense for its own critical infrastructure and a deeper understanding of the evolving threat landscape.

From Code Creators to Cyber Shields

Behind XBOW's advanced technology is a team with a unique and powerful pedigree. The company was founded by key figures who pioneered GitHub Copilot, the revolutionary AI tool that assists software developers in writing code. This background provides them with an unparalleled understanding of how modern software is built, which they now leverage to understand how it can be broken—and ultimately, secured.

“There isn’t a better team to tackle this challenge than the one who pioneered the AI coding revolution with GitHub Copilot, bringing unparalleled expertise in both how software is built and how it is secured,” Maltiel noted.

This human ingenuity is at the core of XBOW’s mission. The platform is not designed to replace human security experts but to amplify their capabilities. By automating the laborious and time-consuming process of vulnerability discovery and validation, it frees up security professionals to focus on higher-level strategic tasks like threat analysis, remediation, and architectural improvements. It transforms the security workflow from a reactive, manual process into a continuous, proactive, and intelligent system.

Oege de Moor, Founder and CEO of XBOW, highlighted the strategic value of the partnership. “Liberty Global has deep expertise in scaling technology businesses globally, and their commercial network will be vital as we enter our next phase of growth,” he said. “With partners like them operating alongside us on the front lines, we’re accelerating our mission to stay ahead of AI attacks to defend the world together.”

A Billion-Dollar Bet on Autonomous Defense

The confidence in XBOW’s approach is reflected in its financial backing. The press release mentions a round of over $150 million, part of a larger fundraising effort. Research indicates this is an extension of XBOW’s Series C round, which was led by DFJ Growth and Northzone and valued the company at over $1 billion, officially launching it into “unicorn” status. The total capital raised by the company now exceeds $270 million.

The caliber of the investor syndicate speaks volumes. Strategic investors like Accenture Ventures are integrating XBOW’s technology into their own security offerings to help clients shift to AI-driven defense. The participation of NVentures (NVIDIA's venture arm) and Samsung Ventures further signals the importance of AI-native security to the world's leading technology hardware and software ecosystems.

The investment from this powerful coalition validates the market's shift toward autonomous security. As enterprises continue their rapid adoption of AI, the attack surface expands, and the speed of development cycles accelerates. In this environment, periodic, manual security testing is an outdated and inadequate defense. The success of XBOW and the significant capital flowing into the offensive AI security space demonstrate a broad consensus: the future of cyber defense is autonomous, continuous, and intelligent.
