Tel Israeli cybersecurity startup Noma Security, founded in 2023, has secured a $100 million Series B funding round, led by Evolution Equity Partners, with continued support from Ballistic Ventures and Glilot Capital Partners. This latest investment brings the company’s total funding to about $132 million, positioning it as one of the most well-funded startups in the emerging AI security market. The round underscores the growing urgency around securing agentic AI autonomous systems that perform tasks and make decisions without direct human oversight.
Rapid Growth Out of Stealth
Noma Security only emerged from stealth in late 2024, but its trajectory has been nothing short of extraordinary. In less than a year, the company has seen its Annual Recurring Revenue (ARR) grow by more than 1,300%, reflecting surging enterprise demand for solutions that protect data and systems against risks posed by AI agents. Its customer base has quickly expanded across multiple industries, including financial services, life sciences, healthcare, retail, and large technology enterprises. These organizations are increasingly deploying AI agents for customer support, DevOps automation, fraud detection, and even high-value decision-making tasks, but with this adoption comes heightened vulnerability.
What differentiates Noma is its laser-focus on agentic AI risks, which traditional cybersecurity tools struggle to address. Conventional endpoint or cloud security platforms were not designed to monitor, govern, or intervene in the behavior of autonomous agents that can interact with systems, people, and external networks at scale. This specialization has allowed Noma to carve out a distinct leadership position in a fast-evolving security landscape.
What the Platform Does
Noma’s AI & Agent Security Platform provides enterprises with a comprehensive set of tools to discover, monitor, and secure AI models and autonomous agents across their organizations. Its continuous discovery engine scans environments to locate AI assets ranging from code repositories and development tools to production environments and agent frameworks helping organizations understand what AI they are actually running.
Beyond discovery, the platform delivers risk prioritization and governance features that assess vulnerabilities, enforce security controls, and establish policies for safe AI use. This includes detecting rogue or unapproved agents, identifying insecure third-party libraries, and monitoring excessive permissions. By embedding governance guardrails, enterprises can ensure compliance with regulatory requirements and internal standards.
At runtime, Noma provides real-time monitoring and protection, capable of halting unsafe behaviors, blocking malicious prompts, or intercepting harmful outputs. This is particularly crucial in high-stakes industries where AI agents are entrusted with sensitive data, financial transactions, or mission-critical operations. The company is also developing advanced modules for incident response and forensics, giving security teams the ability to analyze attacks or failures involving AI agents and adapt defenses rapidly.
Use of Funds & Expansion Plans
The $100 million infusion will allow Noma to scale its operations on multiple fronts. A significant portion of the capital will be directed toward R&D and product development, with the company planning to expand its engineering and AI research teams in Tel Aviv, one of the world’s leading cybersecurity hubs. This investment will help Noma refine its agentic AI defense technology and stay ahead of increasingly sophisticated threats.
Another core focus is international expansion. Noma is building out its go-to-market presence across North America, Europe, and the Middle East & North Africa . This includes setting up regional sales teams, forging new channel partnerships, and establishing local customer support operations. The company sees these geographies as particularly critical, given both the pace of AI adoption and the intensifying regulatory scrutiny over AI deployment.
The funds will also support strategic alliances with cloud providers, enterprise software vendors, and AI model developers, ensuring that Noma’s solutions can integrate deeply into enterprise ecosystems and cloud environments where AI agents increasingly operate.
Why It Matters Now
The timing of this raise could not be more relevant. Enterprises worldwide are in the midst of a rapid shift from experimental AI pilots to large-scale deployments of agentic AI. According to recent industry research, more than half of Fortune 500 companies expect to integrate autonomous agents into business processes by 2027, and adoption timelines are accelerating. This trend is creating a parallel wave of new attack surfaces, ranging from data leakage and malicious prompt injections to unauthorized transactions and manipulated decision-making.
Noma’s solutions are therefore arriving at a pivotal moment. The risks associated with agentic AI are not hypothetical they are already surfacing in enterprise environments. By providing security, governance, and compliance frameworks, Noma helps organizations unlock the productivity gains of AI while minimizing exposure to new categories of cyber risk.
Challenges & Competitive Landscape
Despite its strong positioning, Noma faces challenges in a competitive and rapidly evolving space. Larger cybersecurity players are beginning to expand their AI security offerings, while other startups are experimenting with adjacent solutions such as LLM firewalls, data privacy tools, and prompt security platforms. For Noma, staying ahead will require continuous innovation, strong enterprise integration, and proof of long-term scalability.
Another challenge lies in customer education. Many enterprises are still in the early stages of understanding the security implications of agentic AI. Noma not only needs to provide tools but also act as a thought leader, helping CISOs and regulators build frameworks for safe AI adoption. Nonetheless, its early traction and focus on agent security position it as a category creator a company that could define standards for how enterprises secure autonomous systems globally.
Broader Implications for AI and Cybersecurity
Noma’s rise reflects a broader transformation in both the AI and cybersecurity sectors. As businesses increasingly depend on autonomous systems, the definition of “digital risk” is being rewritten. Security is no longer just about protecting networks or endpoints it must also extend to AI decision-making processes, interactions, and outputs.
Moreover, regulators in regions like the EU and North America are drafting rules around AI accountability, transparency, and safety. Platforms like Noma’s could become critical enablers of compliance, offering the governance mechanisms companies need to demonstrate that their AI systems are secure, fair, and auditable.
In this sense, Noma is not simply building a product it is shaping the infrastructure of trust that will determine how confidently enterprises embrace agentic AI in the coming decade.
Noma Security’s $100 million Series B is more than just another funding milestone it is a signal that AI security, particularly agentic AI defense, has become a boardroom priority. With rapid revenue growth, a strong investor base, and clear international expansion plans, Noma is positioning itself at the forefront of a critical new cybersecurity frontier.
As enterprises accelerate AI adoption, the ability to secure, govern, and manage autonomous agents will determine not only which organizations succeed, but also how resilient the global digital economy remains. Noma’s journey will therefore be closely watched, both by competitors and by industries racing to harness the power of AI responsibly.
