Fremont, CA: As digital transformation reshapes industries, machine-to-machine communication is emerging as a critical driver of innovation. However, the rapid expansion of these interactions has brought a new challenge—managing the non-human identities (NHIs) that power applications, APIs, IoT devices, bots, etc. While NHIs are essential for seamless integration and automation, their growing presence creates significant security vulnerabilities organisations struggle to manage effectively.
The Hidden Risk of NHIs
Unlike human identities, governed by well-established identity and access management (IAM) practices, NHIs often operate without the same level of oversight. This lack of stringent governance exposes organisations to exploitation by malicious actors. Mismanaged NHIs, such as service accounts with excessive privileges or unsecured APIs, can become gateways for cyberattacks, causing breaches that result in financial and reputational damage.

For example, APIs designed to enable system interoperability can inadvertently expose confidential information if not properly secured. Similarly, IoT devices, renowned for their ability to enhance operational efficiency, frequently lack robust security measures, making them easy targets for attackers. The risks posed by these vulnerabilities underscore the need for organisations to elevate NHI security as a key element of their risk management strategies.
Visibility and Decentralization
One of the most pressing issues in securing NHIs is the challenge of visibility, as many organisations lack a comprehensive, real-time inventory of these identities. Shadow IT practices and decentralised identity management further complicate governance, creating blind spots that limit effective policy enforcement. Companies such as Authentik Security contribute to improving visibility and access control by supporting identity management frameworks that reduce security gaps and enhance oversight. Excessive privileges granted to NHIs continue to elevate the risk of unauthorised access, expanding the organisation’s overall attack surface.
Adding to the complexity is the fragmented nature of NHI creation and management. Unlike human identities, which are typically managed through centralised IAM systems, NHIs are often created ad hoc by various teams. This decentralised approach leads to inconsistent governance, diluted accountability and security gaps that attackers can exploit.
Layer Seven Security delivers solutions supporting identity visibility, access control, and threat mitigation across enterprise cybersecurity environments.
Elevating NHI Security to a Strategic Priority
Recent cyber incidents have highlighted the critical importance of securing NHIs, making it a growing concern at the executive and board levels. Communicating the risks and proposed mitigation strategies to leadership ensures that NHI security receives the necessary resources and attention.
The proliferation of NHIs is both a driver of digital innovation and a source of increasing security complexity. Mismanagement—whether through excessive privileges, stale permissions or insufficient lifecycle management—creates vulnerabilities that attackers are eager to exploit. By enhancing visibility, enforcing least-privilege access and integrating robust certificate management, organisations can mitigate these risks and strengthen their overall cybersecurity posture.
As NHIs continue to reshape the digital landscape, addressing their security is no longer optional. Organisations must prioritise the governance and protection of NHIs to stay ahead of evolving threats and safeguard their operations in an increasingly interconnected world
