Every second, hundreds of automated processes and service accounts access sensitive data without human oversight. These non-human identities (NHIs)—spanning API keys, secrets, tokens and service accounts—operate behind the scenes to power cloud applications, automation and microservices.
NHIs authenticate and execute automated processes between cloud applications and third-party integrations; they allow applications, virtual machines and scripts to access resources securely; and they can generate cryptographic credentials that encrypt and validate communications between automated processes—to name just a few of their uses.
The number of NHIs is growing as organizations race to innovate—or just keep pace with digital transformation. NHIs now often outnumber human users, creating a sprawling network of identities that require immediate attention.
Modern architectures—from DevOps pipelines to serverless computing—rely heavily on NHIs. This creates opportunities for bad actors, where multiple permissions, when exploited together, can lead to catastrophic breaches. Left unsecured, NHIs become prime targets for cyberattacks.
OWASP released its 2025 top 10 risks associated with NHIs, highlighting that a lack of monitoring, excessive permissions and credential mismanagement are just a few of the key issues that can lead to unauthorized access, attacks on infrastructure and data breaches. Unauthorized or poorly managed NHIs can inadvertently grant attackers lateral movement across systems. Such shadow access invites attackers to exploit systems, exposing sensitive data and resources without anyone even knowing.
Security teams often struggle to track these interactions due to the complexity of managing NHIs across cloud and on-premises resources.
Legacy identity and access management (IAM) systems are typically ill-equipped to handle the nuances of NHIs. Designed primarily for human users, these systems have two key weaknesses in relation to NHI.
• Lack Of Visibility: Legacy IAM systems fail to provide insight into how NHIs interact with resources, leaving organizations with significant blind spots.
• Focus On A Reactive Approach (Versus Proactive): Vulnerabilities are detected only after exploitation, limiting the ability to proactively secure systems.
Modern IAM must evolve to secure NHIs by leveraging automated detection, risk prioritization and real-time analytics to mitigate risks before they escalate.
To address the growing risks associated with NHIs, here are five best practices for organizations to adopt proactive strategies:
1. Establish full visibility. Use tools like risk engines and query analytics to map IAM vulnerabilities across NHIs. This approach reveals patterns of cloud data exposure, excessive privileges or overlapping permissions and exploitability. SaaS management capabilities can help reveal which vulnerabilities carry the greatest potential impact.
2. Automate risk detection and remediation. Deploy automated detection mechanisms to identify and address lateral movement, chained access and other high-risk scenarios. Ensure continuous monitoring and timely alerts to reduce reaction times and strengthen overall security posture.
3. Establish governance for NHIs. Implement strict policies to govern NHIs, such as enforcing expiration dates for access keys and conducting regular audits of service accounts. Secure service principles and tokens by aligning with established frameworks that include governance recommendations.
4. Integrate proactive security measures. Adopt a risk-driven IAM strategy that prioritizes areas with the highest exposure and exploitability. Implement a system for monitoring SaaS usage and leverage operational data to predict vulnerabilities and prevent breaches before they occur.
5. Educate and empower security teams. As with all areas of cybersecurity, employees can be a robust bulwark or an extraordinary vulnerability. Regularly provide specialized training on the risks posed by NHIs and equip teams with tools that focus on high-priority threats to minimize alert fatigue.
6. Move to more modern security postures for NHIs. API keys are useful and easy, but there are better ways of providing secure authentication for NHIs. Leverage signed JSON Web Tokens (JWTs) for authentication so that they can't be reused if compromised. Use role-based access where you don't need to have a static credential.
The rapid adoption of cloud technologies and automation has made securing NHIs a top priority. It has also made clear that traditional IAM approaches fail to meet the challenges they introduce. Organizations must evolve their strategies to gain visibility, automate remediation and establish robust governance frameworks.
Securing NHIs isn't just about reducing risk; it's about future-proofing your organization in an increasingly automated world. Given the acceleration of automation and cloud adoption, adopting an IAM strategy that addresses NHI vulnerabilities isn't just a priority—it's mission critical.
The question isn't whether your existing IAM approach is up to the task, but how quickly your organization can rise to the challenge.
