Their firsthand experience with the challenges CISOs and enterprises face when adopting AI has shaped Noma’s core mission: to make AI security and governance as seamless and automatic as AI usage itself, thereby fostering confidence in AI adoption.

A Unified Platform for AI and Agents

To achieve this mission, Noma has developed a comprehensive, one-stop-shop security platform meticulously engineered for AI-driven applications and autonomous agents. This platform offers end-to-end security and governance throughout the entire “Data & AI Lifecycle,” from initial development to production and runtime environments. This holistic approach is crucial for addressing the significant blind spots that traditional application security (AppSec) teams often encounter when dealing with data and AI processes. It provides a much-needed layer of protection that legacy security tools simply cannot offer.

Core Capabilities Designed for the AI Era

Noma’s platform is equipped with a suite of capabilities specifically designed to manage the unique risks inherent in AI systems:

AI Security Posture Management: This feature continuously discovers and inventories all AI resources, including code, pipelines, models, runtime applications, and third-party agents. It automatically generates a comprehensive AI/ML Bill of Materials (BOM), providing critical visibility into the AI landscape and pinpointing vulnerabilities and misconfigurations.
AI Application Security: Noma ensures the security of applications throughout the development process, safeguarding the integrity of enterprise customer data from start to finish, whether it’s being used for model training or deployment.
AI Governance and Compliance: The platform ensures that AI deployments adhere to organizational policies and emerging regulatory frameworks, such as the OWASP Top 10 for LLMs and the EU AI Act. This includes managing risks associated with training data usage and ensuring compliance with industry standards.
AI Agent Security: Noma provides specialized defenses for AI agents – AI systems that act autonomously on behalf of users or organizations – to prevent them from performing unauthorized or malicious actions. The platform aims to offer complete visibility and control across all AI environments, from model development to application runtime and autonomous AI agents.
AI Runtime Protection: This capability offers real-time monitoring and control for autonomous AI systems to detect and block threats like prompt attacks, harmful content, sensitive data leaks, and rogue AI agent actions as they happen. This is vital for mitigating risks that traditional security tools often miss.

The Evolving Threat Landscape: The Unique Vulnerabilities of AI Agents

The rise of autonomous AI agents introduces a new category of security challenges that are distinct from those faced by traditional AI models. These agents, by their very nature, operate with a degree of autonomy that can make them susceptible to a wider range of exploits. Their ability to process unpredictable multi-step user inputs, engage in intricate internal execution processes, and adapt to variable operational environments creates new avenues for attack. Furthermore, their capacity to interact directly with screens and applications opens the door to novel threats, such as pop-up attacks designed to mislead agents into taking harmful actions.

Key AI Agent Security Risks Revealed

Industry research has identified several critical security risks associated with AI agents, and Noma’s platform is designed to counter them:

Prompt Injection Attacks: Attackers can embed deceptive instructions within user inputs or contextual data to hijack an agent’s behavior, potentially leading to data leaks or unauthorized actions. Detecting these sophisticated attacks early is a significant challenge.
Memory Poisoning: Adversaries can manipulate an agent’s memory by injecting false or malicious data, corrupting its “memory” and causing it to take incorrect or unsafe actions, often without triggering alerts.
Privilege Misuse and Unauthorized Access: AI agents often operate with the same permission levels as the users running them. If a user has excessive privileges, an agent could execute tasks on servers where it holds administrative rights, leading to severe data breaches. Many businesses are unaware of which AI agents have access to critical systems, creating a major security blind spot.
Data Exposure and Leakage: Users may inadvertently share sensitive or proprietary information with AI agents without fully understanding the risks. Moreover, model responses themselves can leak sensitive information, a risk Noma’s platform actively mitigates.
Model Pollution and Data Tampering: Malicious inputs can be injected into an agent’s Large Language Model (LLM) to manipulate data, altering it in unintended ways, whether by design or through normal user interaction.
Resource Overload Attacks: Hackers can overload an agent with excessive requests, potentially impairing its performance or causing a denial-of-service (DoS) attack, which could destabilize broader systems, especially in multi-agent environments.
AI Impersonation and Spoofing: Malicious actors can spoof or hijack a business’s AI agents to mimic trusted behavior, tricking systems or users into granting unauthorized access or executing harmful actions. AI impersonation of users is already cited as a top threat by many IT leaders.
Audit and Attribution Challenges: The autonomous nature of AI agents makes it difficult to verify whether a human or an AI performed a specific action, complicating auditing, accountability, and compliance, particularly in regulated industries.
