Selected by CISOs and leading investors, the list recognizes the 30 startups shaping the future of security.
Austin, Texas — June 4, 2025 — runZero, the leader in total attack surface management, today announced its inclusion in Rising in Cyber 2025, an independent list launched by Notable Capital to spotlight the 30 most promising cybersecurity startups shaping the future of security.
Unlike traditional rankings, Rising in Cyber 2025 honorees were selected through a multi-stage process grounded in real-world validation. Leading cybersecurity venture firms submitted nominations, and nearly 150 Chief Information Security Officers (CISOs) and senior security executives voted on the final list, highlighting the companies solving the most urgent challenges facing today’s security teams.
runZero was selected for its innovative approach to exposure management and attack surface discovery, helping security teams navigate today’s complex threat landscape. Unlike traditional vulnerability management solutions, runZero delivers complete and accurate visibility into every asset and exposure across internal, external, IT, OT, IoT, mobile, and cloud environments, including uncovering unknown and unmanageable devices and broad classes of exposures that evade other tools.
The company joins a cohort that has collectively raised over $7.8 billion, according to Pitchbook as of May 2025, and is defining the next era of cybersecurity across key areas like identity, application security, agentic AI, and security operations.
“The demand for cybersecurity innovation has never been greater. As the underlying technologies evolve and agentic AI reshapes everything from threat detection to team workflows, we’re witnessing a shift from reactive defense to proactive, intelligence-driven operations,” said Oren Yunger, Managing Partner at Notable Capital. “What makes this list special is that it reflects real-world validation — honorees were chosen by CISOs who face these challenges every day. Congratulations to this year’s Rising in Cyber companies for building the solutions that modern security leaders truly want and need.”
In celebration, honorees will be recognized today at the New York Stock Exchange (NYSE) alongside top security leaders and investors.
“We’re honored to be recognized as a Rising in Cyber 2025 company. runZero is challenging the status quo with a novel approach to exposure management that can finally provide defenders with the attack surface visibility and comprehensive risk detection required to protect complex, dynamic environments,” said Julie Albright, Chief Operating Officer for runZero. “As a disruptor in our space, it’s great to be acknowledged by CISOs who are in the trenches every day and who have struggled with outdated approaches to vulnerability management that are fundamentally broken. This recognition is a testament to the innovative approach we’ve taken and the meaningful impact we are making for teams responsible for securing their organizations against an increasingly challenging threat landscape.”
A new approach to exposure management
Leveraging innovative technology and proprietary discovery techniques, runZero provides organizations with the most complete and accurate visibility across their total attack surface, including unknown and unmanageable assets. On average, runZero enterprise customers report finding 25% more assets than they were previously aware of, with some environments yielding 10x more assets than security teams expected, radically expanding their view of their attack surfaces and the exposures within. These previously unknown assets are often those at the most risk.
Starting with a foundation of comprehensive visibility enables runZero to provide full-spectrum exposure detection across internal and external attack surfaces. Advanced fingerprinting methodologies build detailed, accurate profiles of each asset in the environment using a library of almost 1,000 attributes. This unmatched depth of data enables the platform to identify much broader classes of exposures going well beyond CVEs to identify risks that evade traditional vulnerability and external attack surface management solutions. runZero recently released new risk findings and dashboards, providing a novel paradigm for organizing, addressing, and tracking exposures over time.
