2025 is the year Non-Human Identity (NHI) became a top security priority. Over 50 breaches linked to NHI were reported in just the first half of the year. Gartner formally recognized machine identities as its own category, and startups in this space raised over $400 million in funding.
NHI now touches everything from access management, automated processes, and compliance to incident response and posture management. It deserves the same level of attention as human identity, and that starts with choosing a platform designed to manage it properly.
This guide will break down the top NHI platforms of 2025. For each tool, we’ll explore where they excel, where they fall short, and how to choose the one that fits your team’s infrastructure, scale, and security needs.
Most engineering teams already manage dozens, sometimes hundreds, of non-human identities, even if they don’t call them that. API keys hardcoded into CI configs, shared service tokens, workload identities running inside containers, and automation bots with wide access are all NHIs. And when left unmanaged, they’re one of the easiest ways for attackers to move laterally, escalate privileges, or leak sensitive data.
It also doesn’t help that traditional secrets managers and Identity and Access Management (IAM) tools weren’t designed for this volume or speed. What used to be manageable with static API keys or service accounts has become a constant stream of short-lived identities that spin up and disappear across pipelines, services, and environments. Furthermore, unlike human identities, these non-human entities often lack secure methods of rotation, auditing, and continuous monitoring, which makes identity sprawl a real threat.
Modern NHI platforms are built to handle this shift. They manage short-lived identities at scale, tie access to specific workloads, log every action, and give developers the tools to plug it all into their infrastructure. To help you choose the right fit, we evaluated platforms based on five practical capabilities that impact day-to-day usage.
Choosing an NHI platform comes down to how well it handles modern infrastructure realities, such as:
These are the areas where NHI platforms either hold up or fall apart.
With that in mind, here’s how each platform stacks up across developer experience, access controls, integrations, and operational complexity.
Platform | Developer experience | Policy and access controls | Infra integration | Operational overhead | Audit and visibility | Ideal for | NHI-pricing summary |
---|---|---|---|---|---|---|---|
Doppler | Dev-first and automation-ready | Strong access control, approval workflows, System for cross-domain identity management (SCIM), and enterprise key management | CI/CD, Docker, K8s, Terraform | Low (fully managed, simple to adopt) | Built-in logging and support for Security information and event management (SIEM) systems | Enterprise and fast-moving teams with enterprise security and compliance needs | Free. NHIs are not billed. Only human users count |
Vault | Friction-heavy, requires agents/scripts | Extremely granular with access control lists | Broad (cloud, K8s, custom auth) | High (complex setup and scaling) | Raw logs; external tooling often required | Enterprises with strong infra teams and custom needs | Charged indirectly. NHIs can increase cost |
Infisical | Fast to adopt via CLI, agents, SDKs | Role-based access with flexibility | CI/CD, K8s, Terraform | Medium (low for cloud, more for self-hosted) | Built-in with secret scanning | Startups and mid-size teams prioritizing visibility and developer speed | Charged. NHIs are billed as identities |
Akeyless | Powerful, but setup takes effort | Enterprise-grade policies and Just-in-time access (JIT) access | Multi-cloud, hybrid, Kubernetes | Low (SaaS, no infra to manage) | Dashboards, audit logs, SIEM | Scaling teams that want strong controls without running infrastructure | Charged. NHIs count toward connector and secret usage |
CyberArk | Enterprise-focused, slower to integrate | Deep policy and certificate lifecycle control | Complex (legacy + modern infra) | High (heavy infra and config needs) | Detailed audit, SIEM, and privileged access Management integration | Large organizations with strict regulatory and certificate management requirements | Charged. NHIs are bundled into user or endpoint pricing |
Now that we've seen a high-level comparison, here’s a deeper look at what each platform offers in practice.
Doppler is a secrets management platform built to handle machine identities at scale. It’s designed to fit directly into engineering workflows while still providing the controls, visibility, and security that larger organizations need.
For larger organizations, Doppler offers strong policy controls and compliance features. Teams can define approval workflows with change request policies, manage access with custom roles and user groups, and connect identity systems through SCIM. Enterprise key management (EKM), on-prem secret rotation, and custom activity log retention give security teams more ownership and support for regulatory and incident response needs.
Doppler also includes advanced monitoring through a secret health dashboard and supports dynamic secrets, making it easier to issue short-lived credentials for zero-standing access. Everything can be fully managed via Terraform, making it automation-ready from day one.
Doppler is easiest to manage when adopted and standardized across all services. Partial adoption can make it harder to enforce policy or maintain visibility.
HashiCorp Vault is a secrets management tool supporting various infrastructure and automation use cases. Vault offers capabilities like access control, dynamic credential generation, and security mechanisms for managing non-human identities in large-scale environments.
Despite its strengths, Vault has a high operational cost. Setting it up in a secure and highly available configuration requires significant time and infrastructural knowledge. Vault also doesn’t treat machine identity as a first-class concept. Instead, it relies on manual mappings between services and authentication methods, which makes it harder to scale in fast-changing environments.
Furthermore, integrating secrets into workloads often requires custom scripts, Vault agents, or sidecars, which slows down deployment and increases fragility. And while Vault logs everything, it doesn’t provide much out-of-the-box visibility; teams need to layer on external tools to get real insights.
Infisical is a secrets manager that manages machine identities and environment-specific secrets within engineering systems. It’s open-source, easy to self-host, and comes with a strong set of features built specifically for real-world infrastructure.
Self-hosting Infisical introduces some operational overhead. You’ll need to manage supporting components like databases and Kubernetes operators, which take planning and ongoing maintenance.
Furthermore, Infisical’s universal auth for generating machine tokens is flexible, but configuring tokens requires effort and a clear understanding of how permissions and lifetimes are applied. Infisical is a strong option for early-stage teams prioritizing visibility, versioned configuration, and self-hosting flexibility. But you’ll want to evaluate how it scales if you're aiming to support multi-team or compliance-heavy use cases.
Akeyless is a cloud-native platform built for secrets and machine identity management. It handles static and dynamic secrets, ephemeral credentials, and encryption workflows, all without requiring teams to run their own infrastructure. Its zero-knowledge architecture is designed to minimize trust, and it supports a wide range of enterprise authentication methods.
Akeyless gives teams a lot of control, but that flexibility comes with setup complexity. Configuring workload identity, secrets injection, and policy rules, especially in Kubernetes, requires a strong understanding of how the platform is structured.
CyberArk provides identity security products and has recently expanded its focus to include NHI management. After acquiring Venafi, CyberArk now offers a full suite for machine identities and secrets and powerful tools for managing certificates.
CyberArk’s architecture leans toward static identity models, which can be a poor fit for modern environments where machine identities are constantly created and destroyed. Keeping its inventory accurate and synced in dynamic systems like Kubernetes or serverless platforms takes extra effort, and it’s not always built with fast-changing infrastructure in mind.
Don’t start by comparing features. Start by figuring out where your non-human identities live, what cloud resources they touch, and how they affect your security posture and attack surface. Make a list of the services, pipelines, environments, and automated processes that rely on machine credentials or secrets. Ask:
Once you have that mapped out, focus on your team's priorities.
Choose a platform that fits your current setup, but won’t become a bottleneck when your team grows or your security needs increase. Ready to see how this works in practice? Schedule a Doppler demo to see how it supports both fast-moving teams and strict enterprise requirements.
