BigID's platform includes a foundational data discovery platform combining data classification and cataloging for finding personal, sensitive and high value data - plus a modular array of add on apps for solving discrete problems in privacy, security and governance. Automate scans, discovery, classification, workflows, and more on the data you need - and find all PI, PII, sensitive, and critical data across unstructured and structured data, on-prem and in the cloud. BigID uses advanced machine learning and data intelligence to help enterprises better manage and protect their customer & sensitive data, meet data privacy and protection regulations, and leverage unmatched coverage for all data across all data stores.

Defakto Security offers a robust platform that authenticates every automated interaction by providing temporary, verifiable identities to non-human entities like services, pipelines, AI agents, and machines, thereby removing the need for static credentials, API keys, and enduring privileges. Their comprehensive non-human identity and access management solution facilitates the identification of unmanaged identities across diverse environments such as cloud, on-premises, and hybrid settings, the issuance of dynamic identities in real time based on policy specifications, the enforcement of least-privilege access principles, and the generation of complete audit-ready logs. The solution comprises several modules: Ledger, which ensures ongoing discovery and governance of non-human identities; Mint, which automates the creation of purpose-specific, temporary identities; Ship, which enables secretless CI/CD workflows by eliminating hard-coded credentials; Trim, which optimizes access rights and eliminates excessive privileges for service accounts; and Mind, which safeguards AI agents and large language models using the same identity framework employed for workloads. Each module plays a critical role in enhancing security and streamlining identity management across various operational contexts.

Keycard is an advanced identity and access management platform tailored for the era of agent-driven technology, facilitating secure connections among AI agents, users, services, and APIs through real-time identity controls driven by policies. Instead of relying on static secrets, it generates dynamic, short-lived access tokens and accommodates federated identity systems to unify users, agents, and workloads within a decentralized authorization structure. Developers can leverage convenient SDKs compatible with popular frameworks, enabling them to create applications aware of agents without needing extensive IAM knowledge. The platform’s data architecture encompasses identity-validated agents, tasks, tools, and resources, which facilitate the establishment of logical zones equipped with permissions that are context-aware and subject to auditing. Additionally, security teams have the capability to formulate deterministic, task-oriented policies that clarify who (whether a user or agent) is permitted to perform certain tasks on specific resources under designated conditions, ensuring complete transparency in access control. This comprehensive approach not only enhances security but also improves operational efficiency across various systems.

Linx Security is an innovative identity security and governance platform that leverages AI to provide organizations with comprehensive visibility and control over the complete identity lifecycle. This platform empowers teams to effectively map, monitor, and manage both human and non-human identities across various applications, cloud setups, and on-premises systems, significantly minimizing blind spots and reducing the potential for identity-related attacks. By offering an integrated solution that merges identity, security, and IT operations, Linx allows organizations to efficiently manage access, implement policies, and ensure compliance from a centralized point of operation. Through the use of AI-driven analytics, Linx continuously evaluates identity relationships, entitlements, and access behaviors to identify risks, irregularities, and vulnerabilities, such as inactive accounts, excessive permissions, insufficient authentication measures, or absent security protocols. Additionally, it features capabilities like identity security posture management, just-in-time access, and lifecycle automation, enabling businesses to eliminate standing privileges and enhance their security posture. Ultimately, Linx Security provides a holistic approach to identity management that adapts to the evolving challenges faced by organizations today.

Idira serves as the advanced identity security platform from Palo Alto Networks, tailored for the AI-driven enterprise and aimed at safeguarding every type of identity—human, machine, and agentic—through a singular control plane. It revolutionizes privileged access management by broadening privilege oversight to encompass all identities that can interact with sensitive systems, encompassing data, applications, cloud services, workloads, endpoints, secrets, certificates, SSH keys, and AI agents. By identifying identity risks, it dynamically adjusts privileges and manages the entire lifecycle from initial access to the conclusion of a session. Idira shifts from a static, always-available access approach to one that emphasizes dynamic privilege, just-in-time access, and zero standing privilege, while ensuring continuous verification and policy-driven controls with real-time enforcement based on identity, device, and contextual factors. Moreover, for human identities, it consolidates privileged access, workforce access, endpoint privilege management, and identity governance, providing organizations with the tools needed to mitigate privilege sprawl effectively. This comprehensive approach not only enhances security but also streamlines operational efficiency across the organization.
