SEATTLE-- XBOW, the leader in autonomous offensive security, announced $35 million in additional Series C financing from investors Accenture Ventures, DNX Ventures, Liberty Global Tech Ventures, NVentures (NVIDIA’s venture capital arm), Samsung Ventures, and SentinelOne S Ventures. The raise extends its previously announced $120 million Series C round, and highlights a broader shift: major enterprises are not just adopting XBOW’s platform, but investing in it as they look to keep pace with increasingly sophisticated, AI-driven attacks.
“We're learning in real time from teams operating at massive scale, and using that insight to build faster for defenders on the front lines,” said Oege de Moor, Founder and CEO, XBOW. “The strongest alignment is when your customers are also in the trenches with you as investors and partners.”
XBOW now serves more than 100 customers worldwide, including several strategic investors in this round, alongside industry leaders like Moderna and Seznam.
“The attacker's point of view is foundational to defense, but difficult to operationalize. XBOW changes this by surfacing exploitable and novel findings at machine speed,” said Alex Krongold, Director, Corporate Development & Ventures, SentinelOne. “Each XBOW agent operates like an extension of our in-house red team, allowing us to scale offensive testing with speed and depth that was previously out of reach.”
Continuous Offensive Security at Machine Speed
Until now, attackers were constrained by talent. Even the most sophisticated adversaries could not target every system, every version, all the time. With AI, attackers now operate continuously and at scale, probing every release, every environment, and every exposed surface. Traditional human-led penetration testing cannot keep pace with AI-driven attackers and modern development cycles.
XBOW uses AI to find and exploit vulnerabilities in applications the way attackers do, running continuously instead of as a point-in-time pentest. It produces validated findings with a low false-positive rate, and can also confirm the exploitability of findings surfaced by other tools so security teams aren't chasing noise.
As software ships faster, continuous offensive testing is becoming a core part of the security stack. XBOW lets customers test more often, cut validation backlogs, and proactively stay ahead of attackers rather than reacting to them.
Fueling Global Expansion
This latest financing further accelerates XBOW’s go-to-market expansion and international growth strategy. With the deep expertise and regional network of DNX Ventures across Asia Pacific, combined with Samsung’s role as a preferred reseller in South Korea, XBOW is expanding its distribution channels and partner ecosystem to accelerate adoption in this key global market.
“We’re seeing accelerating demand for XBOW as organizations look for continuous, intelligent security testing,” said a Samsung Ventures America representative. “As a customer, we’ve experienced the platform’s ability to surface real-world risks with speed and precision. XBOW stands out in a crowded market, and we’re excited to now back this talented team as both a partner and investor.”
The company recently surpassed 250 employees and continues to scale its go-to-market, engineering, and operations teams to meet accelerating enterprise demand. As XBOW enters its next phase of growth, it remains focused on expanding its global footprint and enabling security teams to operate at attacker speed, continuously, safely, and at scale.
