What Is IAM (Identity & Access Management)?
Identity & Access Management (IAM) is the overarching discipline and set of tools organizations use to establish, verify, and control identities and their access to systems, applications, and data. IAM covers authentication (proving who or what an identity is), authorization (defining what that identity is permitted to do), and administration (creating, updating, and removing identities and their permissions over time). Traditionally built around human employees — with tools like single sign-on (SSO) and multi-factor authentication (MFA) — IAM platforms are increasingly asked to also govern non-human identities such as service accounts, API keys, and application secrets, which follow different lifecycles and behavior patterns than people.
Why It Matters
Most IAM platforms were designed for human users who log in through a browser, complete MFA, and follow predictable working patterns — assumptions that don't hold for non-human identities. Service accounts, API keys, and machine credentials often sit outside traditional IAM's field of view entirely, created directly in cloud consoles, CI/CD pipelines, or SaaS admin panels rather than through the identity system of record. That blind spot matters at scale: NHIs can outnumber human employees 45 to 1, and a typical 100-person company runs 2,000+ of them, most invisible to conventional IAM controls. OWASP's NHI Top 10 (2025) reports that 80% of identity breaches involve a non-human identity, underscoring that an IAM strategy covering only human accounts leaves the majority of an organization's actual identity population unmanaged and unmonitored.
How Cydenti Helps
Cydenti extends identity visibility into the territory traditional IAM tools miss — service accounts, API keys, OAuth tokens, and AI agent credentials that live outside standard human-focused identity systems. Rather than replacing existing IAM infrastructure, Cydenti complements it by discovering, mapping, and continuously monitoring the non-human side of the identity population, connecting each machine credential back to an owner, application, and permission set. Explore how Cydenti's platform brings full non-human identity coverage alongside your existing IAM investment.

Does IAM cover non-human identities like service accounts and API keys?
Traditional IAM platforms were built primarily for human users and often have limited visibility into non-human identities, since service accounts and API keys are frequently created directly in cloud consoles or CI/CD tools rather than provisioned through the central identity system. This gap is why dedicated NHI security tools have emerged to complement conventional IAM.
What's the difference between IAM and IGA?
IAM is the broader operational discipline of authenticating identities and enforcing access at runtime — think login, MFA, and permission checks. IGA (Identity Governance & Administration) sits on top of IAM and focuses on the oversight layer: reviewing who has access to what, certifying it's still appropriate, and auditing it for compliance.
