AI tools today do far more than answer questions. They build business apps from natural language prompts, work directly with company data, and complete tasks on behalf of users. As these systems take on more responsibility, they also demand stronger security.
This is where identity and authentication platforms come in. They make sure the right people and AI agents get access to the right tools and data. They also save developers weeks of work by handling login and access systems that would otherwise need to be built from scratch.
Every platform brings its own strengths to the table. Some focus on enterprise logins, others help AI agents connect safely with business tools. Here are some of the best platforms our team found worth exploring.
WorkOS
Services: Enterprise SSO, Directory Sync, User Management, Multi-Factor Authentication, Audit Logs
WorkOS is built for companies that need secure login systems. It helps developers add enterprise sign-in, user management, and access control without spending months building these features. The platform also supports directory sync and multi-factor authentication. It is a great choice for businesses creating AI products for enterprise customers.
Auth0
Services: Authentication, Authorization, Single Sign-On, Passwordless Login, Identity Management
Auth0 has been one of the most trusted names in identity management for years. It offers different ways for users to sign in while keeping accounts secure. Developers can quickly add login features without making the process difficult for users. It works well for both small projects and large business applications.
Composio
Services: AI Tool Integration, Secure API Connections, Authentication Management, MCP Integration
Composio is designed for AI agents that need to connect with different software tools. Instead of creating separate login systems for each service, developers can manage everything through a single platform. This makes it easier to connect AI assistants with workplace apps while keeping user accounts protected.
Arcade
Services: Secure Authentication, AI Agent Authorization, API Access Control, Developer Tools
Arcade focuses on helping AI agents access online services safely. It gives developers simple tools to manage permissions and control API access. This helps prevent AI systems from accessing information they should not use. The platform is useful for teams building modern AI applications.
Microsoft Azure Foundry
Services: AI Development, Identity Integration, Cloud Security, Model Deployment, Enterprise AI Services
Microsoft Azure Foundry brings together AI development and Microsoft’s cloud security tools. Developers can build AI applications while using trusted identity services already available in the Microsoft ecosystem. It is a practical option for businesses that already rely on Microsoft products for their daily work.
TrueFoundry
Services: AI Deployment, User Access Management, Infrastructure Security, Model Management, Team Collaboration
TrueFoundry helps teams build, manage, and deploy AI applications. It also provides user management and permission controls, ensuring that only approved users can access projects. The platform works well for companies that run AI systems across different teams and are looking for a simple way to manage access.
Our Recommendation
Every platform on this list has something useful to offer, but two stand out for different reasons. WorkOS is an excellent choice for companies building AI software for business customers. Enterprise login, user management, and security features are already available, which saves both time and development effort.
Auth0 remains one of the safest all-round options. It is easy to set up, supports different login methods, and works well whether you are building a startup product or a large business platform. If you need one platform that covers most identity needs, Auth0 is hard to overlook.
Why Identity Matters More Than Ever
AI agents are getting access to more business systems every year. They can read files, connect with company software, and perform tasks automatically. That also means they can reach valuable information if security is not handled properly.
A good identity platform helps avoid these problems. It checks users, controls permissions, and ensures AI systems use only the information they are allowed to access. As AI becomes a bigger part of everyday work, strong identity management will become just as important as the AI itself.
Final Thoughts: Better Security Leads to Better AI
Building a smart AI application is only one part of the process. Keeping it safe is just as important. A good identity platform protects users, reduces security risks, and helps developers build applications people can trust.
WorkOS, Auth0, Composio, Arcade, Microsoft Azure Foundry, and TrueFoundry all bring something different to the table. Some focus on enterprise customers, while others make AI integrations easier. The best choice depends on the type of application you are building and the people who will use it.
