Onyx operates as a comprehensive AI management platform focused on discovering, safeguarding, governing, optimizing, and assessing AI agents and models utilized within a company. It offers vital insights for security, governance, and AI teams regarding both sanctioned and unsanctioned AI operations across diverse environments such as SaaS applications, cloud services, endpoints, and coding practices, covering elements like prompts, responses, and agent conduct. The inclusion of the AI Security feature strengthens the organization’s defense by identifying vulnerabilities and enforcing proactive protections against possible threats and misuse. In parallel, AI Governance guarantees adherence to security protocols and regulatory requirements by providing opt-in coverage and enabling policy regulations to be expressed in natural language. Additionally, AI Orchestration simplifies the deployment of agents and Multi-Cloud Platforms (MCPs), focusing on enhancing cost-effectiveness, precision, and speed. The AI ROI feature aids in quantifying usage, setting targets, and monitoring outcomes across various organizational sectors. Moreover, the Onyx Guardian Agent acts as a supervising AI, consistently detecting risks and addressing challenges throughout the platform, which allows organizations to manage a vast array of agents efficiently. Ultimately, Onyx equips businesses to leverage AI’s full capabilities while ensuring control and diligent oversight, fostering a secure and compliant AI ecosystem. This not only enhances operational efficiency but also encourages innovation within the organization.

Pi is an innovative product security platform that aims to build a strong institutional memory for security, enabling organizations to proactively detect, resolve, and prevent recurring vulnerabilities without interrupting their development workflows. By continuously integrating diverse elements such as code repositories, past incidents, reports from penetration tests, and support tickets into a dynamic repository, it offers critical insights into the organization's software development and security methodologies. When a vulnerability is detected, Pi identifies its underlying architectural cause and scans the entire codebase for similar issues, promoting a thorough resolution rather than tackling each problem individually. The remediation strategy is customized to fit the specific programming languages, architectural designs, and coding standards of the organization, allowing it to blend seamlessly into developers' daily activities. Furthermore, the knowledge gained from the system is converted into preventive measures that can be applied within integrated development environments (IDEs) and during pull requests, effectively stopping known insecure practices before they reach production. This holistic approach not only reinforces security but also optimizes the development lifecycle, making security an essential component of the programming process. Ultimately, by embedding security into the development fabric, Pi empowers organizations to innovate confidently while maintaining a strong security posture.

Opal Zero acts as a governance platform designed for AI agents, offering just-in-time access management by systematically cataloging each agent, associating them with a responsible owner, assessing access requests, and executing decisions via the existing MCP gateway. This all-encompassing solution enables organizations to sustain a cohesive inventory across diverse identity providers and AI platforms such as Okta, Entra, Anthropic, OpenAI, Bedrock AgentCore, and Cursor, thereby clarifying the permissions assigned to each agent and their corresponding ownership. The Risk Center identifies access that could be misaligned with its intended application, unassigned, or excessively broad, directing these issues to the relevant owner while providing immediate options for corrective action. Paladin evaluates requests against predefined policies and contextual information, identifies the most limited access pathways, respects ownership boundaries, and explains the justification for each decision made. By scrutinizing actual user behavior, Policy Insights reveals cases of unnecessary access and recommends improvements to access policies, aiming for a proactive approach rather than reactive fixes. Gateway Enforcement guarantees that sanctioned access decisions are executed as precise, temporary policies within the current gateway framework, thereby cultivating a more secure and well-organized structure for managing AI agents. Additionally, this platform's robust analytics capabilities help organizations to adapt and refine their governance strategies continuously, ensuring that they remain aligned with evolving operational needs.

The NVIDIA Open Agent Safety Platform is an open reference framework dedicated to the continuous monitoring and management of AI agents' behavior, allowing organizations to maintain agents that are isolated, observable, auditable, and operate within established parameters. This platform combines real-time governance with ongoing threat detection and policy enforcement through hardware isolation, ensuring that enterprise AI agents are protected throughout their lifecycle, from initial testing to deployment. Complementing this, the NVIDIA OpenShell provides an open-source runtime that separates the execution of agents from their access to data, tools, and external systems, employing sandboxed environments and a zero-trust policy to tightly control agents' visibility and interactions. Policies are applied externally to the agent processes, thereby reducing the risks linked to unexpected behaviors. Additionally, NVIDIA Sentry bolsters security by implementing a thorough monitoring system for agent requests and responses, validating agent identities, and managing access to data, tools, APIs, and services, with the ability to isolate agents when required. This multifaceted strategy not only protects AI agents but also fosters a secure and regulated operational environment for organizations, ultimately enhancing their confidence in AI deployment. With such safeguards in place, companies can innovate with AI while minimizing potential risks.

Vulnify functions as a specialized runtime authorization platform designed for developers and security teams who are building AI agents that engage with various tools or APIs. Before a tool is executed, the agent sends over action metadata, which includes information about the agent, the specific action, the resource involved, the target destination, and the number of records affected, after which it receives a decision labeled as ALLOW, REVIEW, or BLOCK, along with a risk score between 0 and 100, complete with explanations. Users can create and test YAML policies via a command-line interface, and they also have the option to integrate checks through Node.js or Python SDKs, a REST API, or numerous adapters compatible with their agent frameworks. Furthermore, the monitor mode allows for the logging of decisions without disrupting ongoing actions, and should Vulnify become unavailable, a fail-closed mechanism will halt actions unless a fail-open configuration is activated. An audit log that employs hash chaining keeps a detailed record of decisions made, and paid subscription plans can include human review processes to enhance oversight. Common applications for Vulnify involve monitoring data exports, controlling external communications, processing financial transactions, and other agent-initiated activities. It's essential to highlight that Vulnify prioritizes the assessment of action metadata rather than the actual content of the impacted records, ensuring an efficient and focused approach to authorization. By implementing this innovative system, organizations can significantly bolster their security and compliance in AI-driven operations, ultimately fostering a safer digital environment for their applications.

Mountain Theory is AI security for companies running autonomous AI agents. Before an agent's action runs, Mountain Theory checks it against your rules and allows it, holds it for a person to approve, or blocks it. It stops an agent working around a block, catches an agent drifting off the task it was given, and stops new bad behavior on the day it first appears, with no new rule needed. It also keeps personal data from leaving and blocks instructions hidden in documents. Rules are written in plain English with no code. Every decision is logged for your auditor. It works with any AI you already use, in your environment or the cloud. We publish our recorded tests, misses included.
