The Non-Human Identity Crisis: The Hidden Attack Surface
Undermining Cyber Resilience

While organizations have spent years securing human identities, a far larger and more dangerous risk has emerged in the shadows: nonhuman identities (NHIs). From service accounts and API keys to OAuth tokens and AI agents, these machine identities now outnumber humans by as much as 144:1 yet remain largely unmanaged and unprotected.

This growing “identity blind spot” has become a prime target for attackers. Unlike human credentials, NHIs are often overprivileged, rarely rotated, and difficult to monitor making them ideal for persistence, lateral movement, and long-term compromise.

In this eBook from Commvault, you’ll uncover how attackers exploit non-human identities to bypass traditional defenses and why securing them is critical to modern cyber resilience. Learn:

• Why non-human identities represent one of the fastest-growing attack surfaces
• How attackers pivot from human compromise to machine-level
  persistence
• The critical vulnerabilities unique to NHIs, including token theft
  and service account sprawl
• Real-world attack patterns that demonstrate the strategic value
  of NHIs to adversaries
• A modern framework for managing and securing NHIs as Tier 0
  assets.
