The proliferation of systems communicating over the internet without human intervention has experienced significant growth in recent years. The rise of the Internet of Things (IoT) has led to increased machine-to-machine (M2M) communications, driving more autonomous interactions between pieces of software code across networks. This surge in digital transformation is further fueled by remote working practices and the expanding realm of e-commerce.

As this trend continues to evolve, there arises a crucial need to manage the identities of these non-human entities (NHIs). These digital identities, tied to various applications, services, and machines within enterprise technology stacks, include bots, API keys, service accounts, OAuth tokens, and other credentials that enable machines or software to authenticate, access resources, and communicate within systems.

Several key factors necessitate the implementation of effective NHI management (NHIM). Firstly, modern IT infrastructures have become increasingly complex, with interconnected systems, cloud services, and IoT devices operating autonomously. Managing the identities of non-human entities is essential for ensuring accountability, traceability, and security within these intricate environments.

Secondly, the rise in automation within organizations, driven by agentic AI and the deployment of bots, scripts, and automated workflows, emphasizes the importance of proper identity management to prevent unauthorized access and misuse. The execution of tasks autonomously by non-human entities underscores the critical need for robust NHI management practices.

Lastly, the prevalence of cybersecurity threats targeting NHIs, particularly those in the IoT sector operating without human intervention, poses significant risks. Weak authentication mechanisms, misconfigured permissions, and inadequate monitoring can leave non-human entities vulnerable to exploitation by cybercriminals, leading to potential data breaches, system compromises, and service disruptions.

The nascent NHI market is currently dominated by startups, with companies like Aembit, Andromeda Security, Astrix, and others spearheading innovation in the field. While some vendors focus on NHI security specifically, others offer broader NHIM capabilities, often referred to as NHI governance. The market presents significant potential for acquisition by larger identity security platform vendors, with several startups already being acquired by industry leaders in recent years.

Omdia predicts that the growth of NHIs will continue to accelerate, further expanding the threat landscape for enterprises. The adoption of cloud technology, microservices, and DevOps practices will contribute to the proliferation of non-human entities within organizational environments. As machine identities already outnumber human identities by a significant margin, the opportunities for vendors in the identity security market are vast and likely to increase in the future. Enterprises must remain vigilant and proactive in managing the identities of non-human entities to mitigate risks and ensure the security of their systems and data.
