Most enterprises still run identity and access on spreadsheets, tickets, and organizational knowledge—until a breach or audit exposes a harder truth: no one can clearly explain who can do what in their most critical systems, or why. If you still treat Identity and Access Management (IAM) as IT plumbing rather than your primary control surface, you are accepting invisible financial and regulatory risk you cannotreally quantify.
Why identity is now your primary control surface
Identity has quietly become the primary way attackers gain access and move laterally. In its 2024 data breach analysis, the Identity Theft Resource Center highlighted that compromised credentials and misuse of access rights remained central to many major incidents, driving up both costs and regulatory attention. For a CISO accountable to the board, access management is no longer an operational topic—it is a core element of risk governance.
Weak IAM shows up in very specific ways:
- Unauthorized production changes that bypass change control and create financial misstatement risk.
- Toxic segregation-of-duties (SoD) combinations that enable fraud or manipulation of financial results.
- Abandoned human and non-human accounts in SaaS and cloud that become invisible backdoors into sensitive data.
At the same time, NIST’s Zero Trust Architecture (SP 800-207) puts identity at the center of the “never trust, always verify” principle, making policy-led IAM a prerequisite for any credible Zero Trust roadmap. Boards and regulators increasingly expect CISOs to demonstrate that identity risk is governed end-to-end, not just patched over in pockets.
What a strong IAM framework actually is
Strong IAM is not a list of tools; it is a framework: the policies, processes, and platforms that govern digital identities and access across their full lifecycle. A good framework provides a single, coherent way to define who gets access, under what conditions, how that access is used, and when it should be revoked.
For enterprises, that framework typically rests on five pillars:
- Identity lifecycle management: Automated joiner–mover–leaver flows for employees, contractors, partners, and non-human identities, keeping access aligned with real roles.
- Authentication: Single sign-on and multi-factor authentication, augmented by risk-based checks, providing consistent verification across critical assets.
- Authorization and policy: Role- or attribute-based models that embed SoD and least privilege into how access is granted, not just how it is reviewed.
- Identity Governance and Administration: Access certifications, SoD analytics, and policy enforcement that keep entitlements under continuous governance.
- Privileged Access Management: Tight control and monitoring for high-risk and administrative accounts, ideally with just-in-time elevation and session oversight.
The key stance for CISOs is to treat this as an identity control plane: the place where risk appetite and regulatory obligations are translated into enforceable access policies.
The real cost of weak IAM
Most CISOs feel the drag of weak IAM before they see a headline breach. What looks like operational friction is often identity debt accumulating in the background. Quarterly access reviews still run on spreadsheets, burning weeks of senior time and still missing high-risk SoD conflicts until auditors flag them. HR, IT, and application owners work from different “sources of truth,” leaving orphaned accounts and lingering admin access in critical ERP and SaaS platforms.
Gaps in MFA and access policies are particularly dangerous. Long-tail SaaS, legacy systems, and machine identities often fall outside the standard pattern, creating exploitable holes in what otherwise appears to be a strong security posture. A 2024 round-up of major breaches emphasized how often attackers exploited inconsistent access controls and over-privileged accounts to escalate impact and extend dwell time.
These are not just security metrics:
- Finance teams face extended audits, potential restatements, and higher assurance costs.
- Transformation programs—from ERP modernization to AI initiatives—slow down because getting the right access in place becomes a project in itself.
- In conversations with boards and regulators, CISOs are forced to rely on partial, manual evidence rather than a defensible picture of access risk.
What “good” looks like from the CISO’s chair
A strong IAM framework changes the question from “Did we close this access ticket?” to “Should this access exist at all, and can we prove it?” That requires an explicit, opinionated model for how identity will work across the enterprise.
In a mature state, you typically see:
- Policy-first design: Business roles, SoD rules, and risk policies are defined centrally and then implemented consistently in IAM platforms and connected systems.
- Continuous governance: Certifications, SoD checks, and anomaly detection operate as ongoing processes, not just quarter-end events.
- Identity as the anchor for Zero Trust: Every access request—human or machine—is authenticated, authorized, and evaluated against real-time context and risk, aligned with NIST 800-207.
- Full lifecycle coverage: Joiner–mover–leaver processes automatically drive access changes across on-prem, cloud, and SaaS environments, including service accounts and API keys that previously fell through the cracks.
When enterprises reach this point, the benefits are tangible:
- Faster onboarding and change: New hires, acquisitions, and project teams get appropriate access in hours, not weeks—without bypassing controls.
- Lower identity-driven incident risk and a smaller blast radius when something does go wrong.
- Predictable, shorter audits, with auditors able to independently verify “who has access to what and why” from centralized evidence.
Questions every CISO should be asking
To understand whether your IAM framework is genuinely strong start with a few hard questions:
- Can we produce a single, accurate view of high-risk Segregation of Duties conflicts across ERP, SaaS, and cloud within minutes, including clear ownership for remediation?
- For any given identity, can we see what they can do in our critical systems and the full approval trail for each access grant?
- When someone changes roles or leaves, can we prove that all their accounts, tokens, and privileged access are updated or revoked within defined SLAs?
- Can we govern and monitor non-human identities in ERP, SaaS, and cloud platforms, and can we prove least privilege and continuous certification?
- Can we continuously detect policy and segregation-of-duties violations and trigger remediation workflows before they become audit or security incidents?
If the honest answer to any of these is “only with a lot of manual work,” the issue is not just tooling; it is the absence of a coherent IAM framework that the board can rely on. As a CISO, your next step is to set a clear identity control vision, align it with your Zero Trust and compliance roadmaps, and insist that new initiatives plug into that framework rather than inventing their own access model.
