“Identity-related incidents are on the rise, emphasizing the need for strong identity security measures.” That’s not a marketing line. That’s said by Jeff Reich, Executive Director of the Identity Defined Security Alliance (IDSA), after the group’s 2024 Trends in Identity Security report found that 90% of organizations had faced at least one identity-related incident in the past year.
Numbers like that raise an obvious question: if almost everyone is getting hit, why do so few companies actually know how mature their own identity program really is? That’s exactly what an identity security maturity model is built to answer, and it’s worth being clear-eyed about what identity security actually covers before going any further.
Most companies don’t lose control of identity because they picked the wrong tool.
- They lose control because controls grow unevenly.
- Multi-factor authentication might cover full-time staff but skip contractors.
- Provisioning might be automated for SaaS apps while admin accounts are still handled through email threads.
- Access reviews might technically happen, yet nobody checks whether the access removed actually matches what was flagged.
An identity security maturity model gives you a way to measure this unevenness instead of guessing at it.
What Is an Identity Security Maturity Model?
An identity security maturity model is a structured way to evaluate how well an organization’s identity and access program actually functions, not just whether the right tools are installed. It looks at authentication, lifecycle management, governance, privileged access, and monitoring, and scores each one based on consistency and proof, not intention.
The distinction matters because deploying a control and operating it well are two very different things. A company can technically “have” MFA and still sit at a low maturity level if half its legacy systems quietly bypass it. A maturity model forces that inconsistency into the open instead of letting a checkbox hide it.
Why an Identity Checklist Isn’t the Same Thing
A checklist tells you a control exists. An identity security maturity model tells you whether that control is enforced everywhere, monitored properly, and improved over time. This is the part most organizations get wrong when they self-assess.
Teams that run quarterly access reviews on the applications their identity provider happens to know about often describe themselves as advanced. But the moment an auditor asks for a complete list of every application in use, including the shadow SaaS tools nobody registered, the real picture surfaces. Maturity isn’t about what you’ve deployed. It’s about what you can prove.
Why Bothering With This Actually Pays Off
Identity has quietly become the front line of enterprise security. Between cloud sprawl, remote teams, and a growing pile of machine identities, the attack surface has expanded far past what a simple access list can capture.
The same IDSA report found that 84% of organizations that suffered an identity-related breach said it caused a direct business impact, not just an inconvenience for the security team.
Supporting point: Running a proper identity security maturity model assessment surfaces the exact gaps, like orphaned accounts and unmonitored service accounts, before they turn into headlines.
A few concrete payoffs worth mentioning:
- Fewer blind spots: Inconsistent MFA, shared admin credentials, and stale accounts get caught before an attacker finds them first.
- Smoother audits: Frameworks like SOX, HIPAA, and PCI DSS increasingly expect proof of identity governance, not just policy documents.
- Less manual grind: Mature programs automate onboarding, offboarding, and access requests instead of routing everything through tickets and spreadsheets.
- Clearer board conversations: A maturity score gives CISOs a measurable way to justify identity spend instead of relying on gut feeling.
When access reviews run continuously instead of once a year as a box-ticking exercise, you’re not just satisfying an auditor. You’re building genuine identity resilience against threats that specifically go after dormant or over-privileged accounts, which is exactly where most breaches quietly begin.
The Levels of the Identity Security Maturity Model
Every identity security maturity model, whichever version you follow, tends to describe a similar climb. Here’s a practical breakdown of what each stage actually looks like in day-to-day operations.
Level 1: Ad-hoc. Access decisions live in someone’s inbox. Passwords are the main line of defense, offboarding is inconsistent, and nobody can say with confidence how many applications the company actually uses.
Level 2: Defined. Policies exist on paper, MFA covers privileged users and core systems, and HR-driven provisioning handles the basics. The catch: enforcement is strong where tools reach and weak everywhere else.
Level 3: Managed. This is where an identity security maturity model starts paying real dividends. MFA is universal, SCIM-based provisioning is standard, access certifications run on a set schedule, and privileged accounts sit inside a vault instead of a spreadsheet.
Level 4: Optimized. Authentication becomes adaptive, reacting to device posture, location, and behavior rather than static rules. Machine identities get proper visibility, and IAM data feeds directly into SIEM and SOAR platforms for faster detection.
Level 5: Innovating. Passwordless access is the default, identity governance covers workforce, partner, and machine identities from one place, and the whole program adjusts itself continuously instead of waiting for the next scheduled review.
Most organizations sit somewhere between level 2 and level 3, with a smaller enforcement footprint than they’d like to admit. As one recent industry analysis put it plainly: the identity security programs most enterprises run today are structurally mismatched with the identity environments they’re supposed to protect, and the mismatch is architectural, not a tooling gap.
Core Areas Any Identity Security Maturity Model Should Cover
A single overall score hides more than it reveals, since companies are rarely equally mature across every domain. Break it down instead:
- Authentication and access control: MFA coverage, SSO adoption, and how well exceptions are actually tracked.
- Identity lifecycle management: How fast onboarding, role changes, and offboarding actually happen, not how fast the policy says they should.
- Access governance: Role-based access, segregation of duties, and whether certifications lead to real remediation. This is usually where the biggest cracks show up, and getting identity governance and administration right is what actually separates a policy on paper from access that’s genuinely controlled.
- Privileged access management: Credential vaulting, session monitoring, and just-in-time access for admin accounts.
- Monitoring and detection: Whether identity logs feed into a centralized system or just sit unused.
- Machine identity security: API keys, certificates, and service accounts, which now often outnumber human users in cloud-heavy environments.
Building the Actual Roadmap
An assessment tells you where you stand. The roadmap is what turns that finding into progress, and it usually follows a similar order regardless of company size.
- Fix the foundational risks first: MFA gaps, orphaned accounts, and shared admin credentials should be closed before anything fancier gets attention.
- Respect the dependencies: Adaptive authentication only works once universal MFA is solid, and just-in-time access needs a mature privileged access program underneath it.
- Set measurable checkpoints: Targets like near-complete MFA enrolment or sub-four-hour deprovisioning give the roadmap something concrete to hit rather than a vague sense of “better.”
- Tie it to business goals: Zero Trust adoption, cloud migration, and compliance deadlines all move faster when identity maturity is treated as part of the plan instead of a side project.
For most teams, the honest bottleneck isn’t ambition, it’s execution capacity. This is usually the point where choosing the right identity security vendor makes the difference between a roadmap that ships and one that stalls at the slide-deck stage.
Bringing It All Together
A maturity score by itself doesn’t fix anything. What actually moves the needle is the roadmap that comes out of the assessment: which gap creates the most risk, which fix comes first, and how the whole identity program eventually lines up with a Zero Trust approach instead of a patchwork of tools bolted together over the years.
If you’d rather not build that roadmap alone, that’s exactly where we come in.

Frequently Asked Questions
What is an identity security maturity model, in simple terms?
It’s a framework that measures how consistently and effectively your identity controls actually operate across the organization, rather than just confirming that certain tools exist. It looks past whether MFA or SSO is “deployed” and asks whether they’re enforced everywhere, monitored properly, and improving over time. Most frameworks score maturity across a handful of areas:
- Authentication and access control
- Lifecycle management (onboarding, offboarding, role changes)
- Governance and privileged access
- Monitoring and machine identity visibility
Why do most companies overestimate their own maturity level?
Because self-assessment tends to compare the program against its intentions rather than its evidence. Gaps outside the identity provider’s visibility, like shadow apps or unmanaged contractor accounts, rarely generate any signal that contradicts a team’s sense of doing well, until an audit or incident forces the question. Teams that run disciplined reviews over their known application list feel thorough, without realizing 20 to 40% of the real estate sits outside that view entirely.
How long does it take to move up a maturity level?
It depends on the transition, but a rough guide looks like this:
- Building a complete inventory plus a documented policy: 4 to 8 weeks
- Extending lifecycle automation across the full application estate: 2 to 3 months
- Layering in continuous monitoring and automated remediation: often within the same deployment cycle if the platform already supports it
Legacy, connector-heavy toolsets tend to stretch these timelines considerably.
Is reaching the highest maturity level necessary for every organization?
Not always. A solid middle tier, with complete visibility, automated lifecycle management, and regular certifications, is enough for many companies to satisfy compliance and reduce day-to-day risk. Higher levels matter more for organizations where identity is a primary attack surface concern, or where audit regimes actively probe what happens between review cycles rather than just checking the paperwork at the end of the quarter.
Does machine identity count in a maturity score?
Yes, and increasingly it’s the deciding factor rather than a footnote. A program can’t realistically claim strong maturity if its inventory ignores the identities, like API keys, service accounts, and workload credentials, that now often outnumber human users in cloud-heavy environments. Older maturity frameworks were written before this shift and tend to underweight it, so it’s worth checking whether any model you use accounts for non-human identities explicitly.
