Enterprises today face a significant workforce challenge that isn't reflected on any traditional organizational chart. Non-human identities—such as bots, service accounts, API keys, OAuth tokens, and machine certificates—have surged in number, often surpassing human identities by a staggering ratio of ten to one. These identities are constantly authenticating and operating across diverse environments, but when neglected, they linger, accumulating privileges and becoming invisible threats. Security experts have started referring to these rogue entities as ghost identities, aptly named given their elusive nature.
This is not a new concern; the security industry has received ample warnings but failed to take decisive action. Recall incidents like the SolarWinds breach, where attackers exploited machine identities with significant access rights that went unnoticed for months, infiltrating 18,000 organizations using these identities without raising alarms. In another case, the 2022 Uber hack can be traced back to a forgotten service account, which opened a pathway to critical internal resources and data. More recently, a breach affecting Okta involved compromised credentials linked to a third-party vendor, illustrating that the risks extend beyond one’s immediate security perimeter.
The Impending Crisis
Fast forward to 2026, and unmanaged non-human identities could manifest as a catastrophic event—specifically, a widespread certificate expiration crisis. Many organizations have issued machine identity certificates with validity periods of three to five years, and as digital infrastructures have expanded rapidly from 2020 to 2022, these certificates are now nearing their expiration dates.
The scenario is straightforward: a certificate expires without notice, resulting in the failure of the services it supports. When applications reliant on that service start to fail, the incident response may struggle to piece together the connections involved, often leading to significant downtime and potential revenue loss. We've seen this happen before; even a single expired certificate took Microsoft Teams offline for millions in 2020. However, the scale of the impending crisis in 2026 could be far greater as many organizations will simultaneously experience outages arising from hidden, ungoverned identities.
Currently, certificate expiration is typically relegated to IT operations, but that perception shifts dramatically when it leads to prolonged service outages that affect customer-facing systems.
Bridging the Structural Gap
The fundamental issue isn't merely negligence; it lies in the architecture underlying identity management. Many tools designed to manage access rights—like role-based access controls and privileged access management platforms—were developed for human users. Non-human identities often evade this framework: they are created to tackle specific issues, endowed with broad access, and frequently left unchecked long after their initial purpose has been fulfilled.
The risks escalate with over-provisioning. Every unmonitored service account represents a potential pivot point for threats, while dormant API keys with expansive access rights open up pathways for exploitation. Ghost identities, particularly those with legacy admin rights, yield a risk that can extend across the entire organization.
Defining Effective Governance
The solution isn't just about deploying new tools; many vendors will insist otherwise. True governance takes precedence and should begin by addressing a crucial question: "What non-human identities do we currently manage?"
This inquiry may seem straightforward but presents complexities. Non-human identities emerge organically across different teams—developers, platform managers, and third-party vendors—and rarely are these actions tracked in a centralized, useful manner. Consequently, most enterprises lack a complete map of their identity estate, resulting in operational blind spots and ineffective governance.
To begin remediation, initiate a discovery sprint focusing on high-risk areas like cloud services, CI/CD pipelines, and third-party integrations. A rough inventory of non-human identities is far more advantageous than operating without any oversight.
Simultaneously, pull data on certificate expirations. Review those due in the next eighteen months, assigning a named owner for each. If no owner exists, classify the certificate as a ghost identity and treat it with the appropriate urgency. This proactive approach directly addresses the looming expiration risks before they escalate into outages.
Additionally, conduct a privilege audit for your most sensitive service accounts. Any non-human entity with admin rights that hasn't been reviewed in the last year should be deemed over-privileged until there's evidence to support otherwise. This presumption of excess can help mitigate significant risks.
These strategies don't require new funding; they necessitate prioritization and commitment from leadership to prevent avoidable crises.
The Larger Issue
Addressing non-human identity management within a single organization is only a partial fix. If only one entity acts, it merely becomes less vulnerable among many that continue to overlook the risk.
The market for managing machine identities is still developing. Three different vendors might offer three distinct definitions for managing non-human identities. Lifecycle standards and objectives remain elusive; respected frameworks like NIST or ISO 27001 may recognize the principle of least privilege but fail to provide actionable guidance for handling numerous unmanaged service accounts across sophisticated hybrid environments.
The core of the challenge lies in specificity—a need for a shared vocabulary, lifecycle standards, and clear regulatory guidance that places NHI governance at the same seriousness as other identity management obligations. Dialogue on these topics is gaining traction with standards organizations and regulators taking note, but the pace is slow, while the threat of impending certificate expirations looms large.
A Ticking Clock
Ghost identities are silent; they don’t resign or request evaluations. They persist until disrupted—be it via a security breach, certificate expiration, or a determined security team that conducts an inventory.
For organizations that neglect to map and govern their non-human identity landscape by 2026, a disruptive event is inevitable. The only question will be whether it arises from a proactive governance strategy or as a reaction to a forced outage.
