Managing identities is no longer limited to employees logging into applications.
Modern enterprise environments include a growing number of non-human identities – workloads, containers, APIs, and other digital entities that interact autonomously. These identities enable applications and services to communicate securely and reliably across dynamic, distributed environments. However, they also introduce complexity and risks that traditional identity and access management (IAM) tools weren’t designed to handle.
Recognizing these challenges, Aembit has built its Workload IAM Platform to address the complexities of dynamic, cloud-native environments. By ensuring secure, seamless interactions between workloads, APIs, and third-party services, Aembit simplifies the management of non-human identities while scaling to meet the demands of modern enterprises. Designed in collaboration with some of the world’s largest companies, our platform helps organizations securely manage workload access across distributed, API-driven systems without introducing operational bottlenecks.
This post explores how Aembit, a platform purpose built for workload identity and access management, helps organizations secure and manage non-human identities at scale. We’ll delve into Aembit’s manageability features, real-world use cases, and practical implementation strategies, concentrating on emerging scenarios such as managing access to AI/LLM APIs, multi-cloud scenarios, and securing CI/CD pipelines.
The Problem: Managing Identities in a Distributed Ecosystem
In the past, enterprise IAM focused primarily on human users – employees, contractors, and partners. Non-human identities have changed the game; today, they far outnumber human users in most organizations. These identities include:
- Workloads: Applications, microservices, and containers that must communicate with databases, APIs, and external services.
- Infrastructure Components: Resources like Kubernetes pods, serverless functions, and cloud services that require secure communication.
- Automation Pipelines: Continuous integration and continuous delivery (CI/CD) systems deploying services at high velocity.
- Access to AI/LLM APIs: Workloads that interact with language model APIs like OpenAI, Anthropic, or Azure OpenAI to support advanced applications such as Retrieval-Augmented Generation (RAG), where systems retrieve external knowledge to augment AI-generated responses.
Managing these identities is challenging due to their unique characteristics:
1) High Volume and Dynamic Scale: Automated systems create and destroy thousands of ephemeral workloads daily.
2) Dynamic Relationships: Workloads frequently change their interactions with other resources as systems evolve.
3) Varied Credentials: Different workloads use various authentication methods, such as tokens, certificates, and API keys.
4) Specialized API Needs: Workloads require tailored access policies to securely retrieve sensitive data from APIs like those exposed by AI/LLM systems.
Organizations risk misconfigurations, unauthorized access, and privilege escalation without an effective and scalable solution.
The Aembit Solution: A Platform for Workload IAM at Scale
Aembit addresses these challenges with a solution built for workload identity and access management. By integrating identity, authentication, and access management into a single platform, Aembit simplifies operations while enhancing security.
- Flexible and dynamic workload identification and authentication.
- The ability to automate access management configuration.
- Delegated administration.
Dynamic Workload Identification and Authentication
Scaling non-human IAM requires a method to authenticate and authorize workloads without bottlenecks or manual intervention. Dynamic identification allows organizations to handle the sheer volume and variability of non-human identities efficiently, ensuring workloads can securely access the resources they need while adapting to rapid infrastructure changes. This eliminates the risks tied to static credentials and reduces the operational overhead of managing large numbers of ephemeral connections.
Aembit uses client identifiers and trust providers to cryptographically identify and authenticate workloads without providing them a fundamental secret (also called “secret zero”). This approach supports both coarse-grained and fine-grained access control:
- Broad Identifiers: Group workloads by Kubernetes namespaces, cloud accounts, or organizational structures, allowing access policies to be applied uniformly to many workloads.
- Narrow Identifiers: Assign unique identifiers to sensitive workloads, such as a specific CI/CD job or Kubernetes service account, for tighter control over access to critical resources.
For example, an organization can use Aembit to apply broad policies for development environments while enforcing precise restrictions for workloads interacting with AI/LLM APIs to ensure secure access to sensitive models and datasets.
Automating Configuration at Scale
Managing non-human identities manually is unsustainable in large environments. Aembit integrates seamlessly with automation workflows and infrastructure-as-code (IaC) tools like Terraform to ensure consistent deployment and management of access policies.
- Terraform Integration: Aembit’s Terraform provider enables organizations to define workload identities and access policies as code. These configurations can be version-controlled and deployed across multiple environments, ensuring consistency and reducing errors.
- API-Driven Management: Aembit’s RESTful API allows enterprises to automate the creation, update, and rotation of access policies and credentials. This minimizes manual intervention and ensures policies remain synchronized with infrastructure changes.
For workloads consuming AI/LLM APIs, Aembit can programmatically configure access credentials and enforce restrictions, ensuring sensitive interactions with external APIs are secure and controlled.
Phased Adoption Through Delegated Administration
Large organizations often struggle to adopt new IAM tools due to concerns about complexity and disruption. Aembit’s Resource Sets feature supports incremental adoption by allowing organizations to:
- Start small by applying Aembit to specific subsets of workloads or environments and expand gradually.
- Delegate administrative responsibilities to individual teams, enabling them to manage their workloads and policies independently.
This phased approach reduces operational overhead while maintaining strong security.
Real-World Use Cases
Securing Access to AI/LLM APIs for Advanced Applications
Aembit’s ability to scale is what sets it apart for managing non-human identities in enterprise environments. Across diverse use cases, Aembit provides the flexibility and security needed to handle the complexity and volume of large-scale operations.

- Dynamic Access Policies for Ephemeral Workloads: Aembit automates the configuration of workload identities and policies during deployment, ensuring secure access for thousands of short-lived workloads without manual intervention.
- Wildcard Support for High-Velocity Environments: Wildcards simplify access management for dynamically generated workloads, such as all containers prefixed with app-pod-* in Kubernetes, enabling efficient scaling without introducing security gaps.
Best Practices for Implementation
1) Consider Starting Small: Begin by deploying Aembit in smaller, security-owned workload environments where the potential impact is minimal and easily manageable. Internal or non-customer-facing applications and services are ideal for this phase, allowing you to assess the platform’s benefits while limiting deployment to a controlled and low-risk scope.
2) Leverage Infrastructure-as-Code: Use Aembit’s Terraform provider to programmatically define and manage access policies.
3) Automate Credential Management: Integrate Aembit’s API with DevOps workflows to dynamically generate short-lived access credentials and update access policies in real time.
4) Adopt Incrementally: Roll out Aembit using Resource Sets, starting with a single team or environment before expanding.
5) Regularly Audit Policies: Use version control and auditing features to track changes to access configurations and ensure they remain aligned with security objectives.
