Nudge Security Raises $22.5M Series A to Secure Workforce AI and SaaS

AUSTIN, TX November 18, 2025 - Nudge Security, the leading innovator in SaaS and AI security governance, today announced Series A funding of $22.5 million led by Cerberus Ventures with participation from existing investors Ballistic Ventures, Forgepoint Capital, and Squadra Ventures. With the new funding, Morgan Mahlock of Cerberus Ventures will join the Nudge Security board.

‍

Nudge Security is the only solution that secures the Workforce Edge—the critical point where employees make daily decisions across SaaS and AI apps that shape an organization’s security posture. Rather than relying solely on rigid security controls that block business innovation, Nudge Security can discover, assess, and guide workforce behavior in real time, transforming security and governance from a barrier to a natural part of how work gets done.

‍

"Nudge Security is at an exciting time in their journey and we’re thrilled to partner with Russ, Jaime, and the team,” said Morgan Mahlock, Director at Cerberus Ventures. “Nudge has cultivated incredible customer loyalty due to its intuitive product that both security teams and employees appreciate for its ease of use. It can deliver immediate value by providing an automated inventory of the SaaS and AI tools being used across an organization. With the vision to expand governance of interactions with SaaS and AI at the Workforce Edge, Nudge will become even more essential for highly distributed, AI-first organizations.”

‍

Since its initial launch in October of 2022, Nudge Security has experienced exponential growth, achieving 3x growth in ARR for two consecutive years, onboarding nearly 200 customers, and delivering rapid product innovation to address customers’ needs for scalable security and governance of workforce use of AI and SaaS.

‍

The explosion of AI, particularly AI embedded throughout the SaaS ecosystem, has introduced unprecedented security challenges as organizations now grapple with hundreds of AI-enabled applications, complex networks of integrations, and non-human identities with access to sensitive data across their environment.

‍

"The difference between AI apps and SaaS has all but disappeared - almost every app has embedded AI capabilities, agents, and integrations. In order to secure workforce AI use at scale, you need to consider the entire SaaS ecosystem, including all SaaS and AI tools, their integrations, and the non-human identities that connect them," said Russell Spitler, Co-Founder & CEO of Nudge Security. "This funding will enable us to continue to expand our capabilities and help organizations confidently embrace innovation while maintaining security and control."

‍

Customer growth

Customers include forward-thinking IT and security teams at cloud-native organizations spanning software, financial services, healthcare, biotechnology, entertainment, and more.

‍

"Nudge Security has been a big win for our security program at Reddit.” says Fredrick Lee, CISO of Reddit. “Within hours of deployment, we gained complete visibility into our SaaS footprint across the organization. It's rare to find a solution that's both incredibly powerful and remarkably easy to use."

‍

Product innovation

In the last 12 months, Nudge Security has shipped over 60 feature releases, adding significant new capabilities to improve AI governance, harden security posture, combat identity security risks, and mitigate third-party risks.

‍

"Our team's ability to innovate at this pace is a direct reflection of our deep understanding of the challenges our customers face," said Jaime Blasco, Co-Founder & CTO of Nudge Security. "We're not just building features—we're solving real problems that security and IT teams encounter every day as they navigate the complexities of AI adoption and SaaS sprawl. This funding allows us to continue pushing the boundaries of what's possible and deliver unparalleled value to organizations looking to embrace innovation without compromising on security."
