The Rise of Non-Human Identities: Navigating the Challenges and Opportunities

As organizations embrace digital transformation and adopt increasingly automated systems, non-human identities (NHIs) have emerged as a critical component of modern IT infrastructures. These identities, which include service accounts, API keys, digital certificates, and even AI agents, play a vital role in enabling seamless communication and interaction between applications, services, and automated systems. However, the rapid proliferation of NHIs has also introduced new security challenges that organizations must address to protect their digital assets and maintain a strong security posture.

The Importance of NHI Security NHIs are essential for the smooth operation of today’s interconnected technological environment. They facilitate real-time data exchanges, API interactions, and automated processes that power a wide range of applications and services. However, the autonomous nature of NHIs, combined with their elevated privileges and the complexity of managing them at scale, makes them a prime target for cybercriminals.

Recent findings from Omdia’s Decision Maker Survey 2025 highlight the growing concern among cybersecurity professionals regarding NHI security. According to the survey, approximately 60% of respondents expressed a lack of confidence in their organization’s ability to adequately secure NHIs. This alarming statistic underscores the urgent need for organizations to prioritize NHI security and adopt comprehensive management strategies to mitigate the risks associated with these identities.

Challenges in Securing NHIs
Organizations face several challenges when it comes to securing NHIs:

1. Credential Security: Many NHIs use plaintext credentials hardcoded in source repositories, making them easily discoverable by threat actors. Additionally, weak or default passwords make these accounts vulnerable to password-guessing attacks.
2. Inventory and Visibility: Maintaining a complete inventory of NHIs across multiple platforms, endpoints, and cloud integrations is a daunting task. This lack of visibility leads to stale, inactive accounts that expand the attack surface and lack clear ownership for remediation activities.
3. Privilege Management: NHIs often receive excessive privileges beyond their operational requirements, violating the principle of least privilege. This situation is further exacerbated when human users bypass privileged access management (PAM) controls by using NHI accounts instead of proper authentication methods.
4. Operational Weaknesses: Credential rotation for NHIs can be challenging due to vaulting issues, unknown dependencies, and required code changes. Moreover, organizations often share NHI credentials across multiple applications and fail to segregate environments, using identical accounts for production and non-production systems.
