Best Non-Human Identity Security (NHI) Tools

Our vision is to provide a digital world where every business can safely build its applications by inherently trusting how they connect to partners, customers, and foundational services. The result: You can build, deliver and maintain better applications that support and empower your customers, without the frustration and exposure risks that come with boldly crossing borders.

The same identity foundation, extended to the new workforce: AI agents. Identity-native governance for everything that acts on your systems.

Cloud-Native SaaS platform built to secure and manage every identity through a single pane of glass.

Apono is a cloud access management vendor positioned in IAM around just-in-time and least-privilege access for human and non-human identities. Its platform replaces standing privileges with access created at request time, enforced with policy guardrails, and revoked automatically. Apono is best suited for cloud-first teams that need granular control across AWS, Azure, GCP, Kubernetes, databases, and SaaS-connected environments, especially where privileged access and access review must be tightly managed.

AppViewX is an automated Certificate Lifecycle Management (CLM) and Public Key Infrastructure (PKI) platform designed to prevent service outages caused by expired certificates. It provides centralized visibility and control over machine identities across multi-cloud and on-premises environments, enabling crypto-agility and rapid modernization of cryptographic standards. The solution complements existing HSMs and CAs by orchestrating the end-to-end process of certificate issuance, renewal, and installation.

Discover, secure, and deploy AI agents responsibly across the enterprise

Britive provides dynamic Cloud Privileged Access Management (CPAM) and Cloud Infrastructure Entitlement Management (CIEM) with patented just-in-time (JIT) ephemeral access across AWS, multi-cloud, SaaS, hybrid, and on-prem environments. It enforces runtime identity access for human, agentic AI, and machine identities via a unified control plane, minting permissions only at execution and auto-destroying them post-task. Recognized by Gartner as a CIEM leader, Britive offers entitlement governance, anomaly detection, and SCIM-based synchronization with IdPs like Okta and Azure AD. Best for organizations needing granular, zero-standing-privilege controls in dynamic cloud ecosystems.

Clutch is an identity security platform that discovers, maps, and governs non-human identities across cloud, SaaS, and AI environments. Using its Identity Lineage® graph, it connects AI agents, service accounts, API keys, OAuth applications, tokens, and secrets to the people, systems, and resources they interact with. This enables security teams to identify excessive privileges, detect identity-based risks, secure machine identities, and enforce governance across human and non-human access, helping organizations safely adopt AI at enterprise scale.

Entro is an NHI (Non-Human Identity) and Secret security platform that focuses on the lifecycle and governance of AI agents, service accounts, and API keys. The solution provides visibility into the "secret behind the identity," mapping connections between machines to reduce identity sprawl and mitigate risks of secret leakage. It replaces manual discovery scripts and siloed secrets management tools with a unified governance engine for the automated enterprise.

Natoma, now part of Snowflake, is an AI agent security platform that enables enterprises to securely deploy and govern AI agents. Built around a hosted Model Context Protocol (MCP) platform, it provides enterprise-grade authentication, fine-grained authorization, policy enforcement, and governance for AI agents accessing enterprise applications and data. With flexible deployment options and support for 100+ pre-built MCP servers, Natoma helps organizations safely connect AI agents to internal tools while maintaining visibility, security, and compliance.

Oasis Security provides an identity control plane specifically designed for non-human identities (NHI) and machine identities such as service accounts, API keys, and secrets. The platform automates the discovery of unmanaged machine identities across hybrid and multi-cloud environments, mapping their access to critical resources to identify over-privilege. It complements traditional IAM by providing automated lifecycle management and remediation for secret rotation and short-lived credentials.

P0 Security provides a cloud identity security platform that focuses on eliminating standing privileges through JIT (Just-in-Time) access and least-privilege enforcement. The solution automates the governance of human, workload, and AI agent identities across multi-cloud environments, ensuring that high-risk access is ephemeral and strictly vetted. It replaces traditional static PAM for cloud environments and complements CSPM by securing the identity layer.

Replace every algorithmically generated random number in critical infrastructure with quantum-sourced entropy that is provably, physically, and absolutely unpredictable.

For over 20 years, SailPoint has helped the world's largest organizations secure and govern every identity, human, machine, and now AI.

Saviynt is on a mission to safeguard enterprises through intelligent, cloud-first identity governance & access management solutions.

We envision a world where more security doesn't equal more obstacles, where protection and experience work together.

Silverfort secures every dimension of identity. We break down the silos of identity infrastructure and point solutions to eliminate security gaps and blind spots once and for all. The result? Identity security without limits, that doesn't slow down the business.

Smallstep provides a Device Identity Platform that enables high-assurance Zero Trust security through automated, short-lived PKI certificates and device-bound authentication. It streamlines authentication workflows to eliminate phishing risks and password dependency by ensuring only managed, healthy devices can access sensitive resources. The solution replaces legacy static credential systems and complements existing SSO providers with granular device-level visibility.

Sonrai Security provides a CIEM platform that analyzes identities, entitlements, and resource relationships across AWS, Azure, and GCP to identify excessive access and misconfigurations. It uses an identity graph to map effective permissions and toxic permission combinations, enabling cloud security, IAM, and compliance teams to discover privilege risks and enforce least privilege. The Cloud Permissions Firewall automates real-time restriction of unused permissions and dormant identities based on actual usage. Extended with CWPP via Sonrai Dig, it links workload vulnerabilities to identity paths for prioritized remediation, distinguishing it from visibility-only CIEM tools.

We deliver trusted computing to modern infrastructure

We are on a mission to secure the autonomous enterprise. As AI agents evolve from simple assistants to independent actors, Token Security provides the identity lifecycle and intent-based access management required to securely turn AI potential into a competitive advantage.

Truffle Security Co. is best known for TruffleHog, an open-source and enterprise secrets-scanning product that fits software supply chain security by finding exposed credentials before they are committed, shared, or deployed. In this category, it focuses on secret leakage across source control, CI/CD, collaboration tools, cloud storage, and other SDLC systems, then verifying whether findings are live to reduce false positives. It is best suited for AppSec, DevSecOps, and security teams that need continuous detection and remediation workflows for secrets sprawl across the software development pipeline.

Secure every AI interaction, from prompt to tool call, guardrails, identity, data policies, and tool authorization in real time.
