Identity Security Debt: What MSPs Inherit From Clients 

MSPs rarely inherit a clean slate.

Whether onboarding a new client or expanding services within an existing account, providers often step into environments shaped by years of identity and access decisions made long before they became involved. Former employees may still have active accounts. Temporary administrator privileges may have quietly become permanent. Shared credentials can persist because replacing them would disrupt established workflows. Service accounts, API keys and integrations created for old projects may still be active.

Individually, these issues can appear relatively minor. Collectively, they create a much deeper challenge: identity security debt.

Similar to technical debt, identity security debt accumulates when short-term decisions, exceptions and incomplete processes create problems that eventually need to be addressed. But instead of outdated code or legacy infrastructure, debt exists in the identities, credentials and permissions woven throughout client environments.

For MSPs, that distinction matters. They may not have caused the debt, but they often inherit the responsibility for uncovering it, determining what access is still legitimate and reducing the overall risk it creates. And unlike a single vulnerability that can be patched, accumulated identity issues may require MSPs to trace years of access decisions, exceptions and workarounds before they can safely unravel them. 

How identity security debt accumulates in client environments

Identity security debt rarely stems from one major security failure. More often, it develops through a series of small decisions that make sense in the moment but aren’t revisited later on. 

• An employee changes roles but retains specific permissions from a previous position. 
• A contractor receives access for a six-month engagement that remains active after the assignment ends. 
• An administrator receives elevated privileges to resolve an urgent issue, but those privileges are never removed. 
• A former employee’s account is disabled in one system but overlooked in another.

The common theme is simple: Access is easier to add than it is to take away. And over time, that imbalance creates an environment where organizations may struggle to answer fundamental questions. 

• Who still has access to critical systems? 
• Which privileges are necessary for someone’s current role? 
• Which accounts belong to people who no longer work there? 
• Who approved an exception, and when was it supposed to expire?

The consequences extend beyond administrative clutter. Stale accounts can preserve unnecessary entry points, and privilege accumulation can give a compromised identity access to systems far beyond what the user currently needs. Incomplete offboarding can leave former employees, contractors or third parties with credentials that remain valid after their relationship with the organization ends.

For an MSP inheriting those types of environments, the challenge is determining which access reflects a legitimate business requirement and which simply reflects years of inherited access.

That distinction becomes harder the longer the debt remains unresolved. Removing an account or privilege without understanding its history can disrupt business operations, encouraging organizations to leave questionable access untouched rather than risk breaking something important.

The operational burden can grow alongside the security risk. Technicians may spend additional time validating ownership, tracing dependencies and determining whether an account or permission can be safely removed. During onboarding, that level of work can slow an MSP’s ability to establish an accurate baseline of the client environment and determine where the most pressing identity risks actually reside.

Identity security debt carries an operational cost. Left unresolved, it can demand increasingly more time and coordination to safely address. 

How service accounts, API keys and secrets create identity security debt

Not all identity security debt belongs to people.

Modern client environments depend on service accounts, API keys, tokens, secrets and other machine credentials that allow applications and automated processes to communicate. Unlike employee identities, these credentials can operate quietly for years without a clear owner or natural offboarding event.

A project ends, but its API key remains valid. An integration is replaced, but the original service account is never retired. A credential created for a temporary automation becomes embedded in a workflow nobody wants to disrupt. Over time, organizations inherit a growing web of machine access that may still function even when nobody can clearly explain why it exists. 

Recent research illustrates the persistence of this problem. GitGuardian’s 2026 State of Secrets Sprawl found that 64% of valid secrets first detected in 2022 were still active and exploitable four years later. Long-lived secrets also represented roughly 60% of the policy violations identified in that research.

That persistence illustrates exactly how security debt takes hold. GitGuardian notes that teams can hesitate to rotate credentials because doing so may cause production outages. Deeply embedded credentials can be especially challenging to rotate, particularly when multiple applications, repositories and workflows depend on them. 

For MSPs, discovery is therefore only the first step. Finding an old credential doesn’t immediately answer the questions that matter most: 

• Who owns it? 
• What systems depend on it? 
• What can it access? 
• What would break if it were revoked?

Those unknown dependencies can force MSPs to balance security needs against operational continuity. Leaving the credential untouched preserves unnecessary access, but removing it without sufficient context could also disrupt a client’s core operations. What initially began as a small lifecycle oversight can eventually require extensive investigation and coordination across multiple systems. 

Without that context, even identified issues can linger. 

And that’s exactly how debt compounds.

Why shared credentials create security and accountability risks

Some identity security debt persists not because it’s forgotten, but because it’s convenient.

Shared credentials are a primary example. An operations team needs access to an administrative portal, so one login is distributed among several co-workers. A legacy application doesn’t support individual accounts. A client has always managed a particular system that way, and changing the process seems more burdensome than leaving it alone. 

The immediate benefit is simplicity, but the long-term cost is accountability.

When multiple people operate through the same identity, individual accountability becomes much tougher to establish, particularly when determining who accessed a system, changed a configuration or exposed a credential. 

Offboarding presents another challenge. When one employee leaves, the credential may need to be rotated for everyone. If that doesn’t happen, knowledge of the login can outlive the person’s legitimate need for access. 

The problem can extend into auditing and compliance efforts, too. Clients may be asked by auditors, cyber insurers, regulators or even their own customers to show who accessed sensitive resources, when that access occurred and whether it was authorized. Shared identities weaken that chain of accountability, leaving MSPs and their clients with less reliable evidence when they need to reconstruct activity. 

These workarounds can also become increasingly entrenched over time. The more users, systems and processes that depend on a shared credential, the harder replacing it becomes.

That’s another characteristic of debt: short-term convenience can lead to lasting operational burden.  

What MSPs should look for when assessing identity security debt

Reducing identity security debt starts with determining how much already exists. 

That makes identity discovery and lifecycle review especially important during client onboarding, when MSPs are establishing their first accurate picture of who and what has access across the environment. But the process can’t end there. Roles change, contractors come and go, new integrations appear and temporary exceptions are created throughout the client relationship.

MSPs should regularly examine questions such as:

• Which inactive or former-user accounts still retain access?
• Which temporary privileges lack a defined expiration date? 
• Which users have retained permissions from previous roles? 
• Which service accounts, API keys and secrets lack clear ownership?
• Which contractor, vendor or guest accounts remain active?
• Where are credentials shared rather than individually assigned?
• Which integrations still have access despite no longer serving an active business need?

The objective isn’t simply to identify more accounts. It’s to distinguish between access a client actively needs and access that has persisted beyond its original purpose. 

That distinction gives MSPs a clearer picture of where excess exposure exists, which issues deserve priority and where corrective action should begin. More importantly, it creates a baseline to evaluate future access decisions, making it easier to recognize when new debt starts to emerge. 

Stop identity security debt from compounding

Not every piece of identity security debt can be eliminated immediately. Legacy systems may remain in production and service accounts may require careful migration. Removing undocumented permissions without first identifying their dependencies can interfere with critical business processes. 

The goal is to keep short-term exceptions from developing into long-term identity debt. 

That requires stronger lifecycle discipline: retiring stale identities, reviewing access as roles change, assigning ownership to machine credentials, replacing standing privilege with time-bound access where possible and ensuring temporary access actually expires.

Keeper offers MSPs a unified identity security platform to put those principles into practice across client environments. By consolidating enterprise password management, privileged access management, secrets management and endpoint privilege management within a zero-knowledge, zero-trust architecture, Keeper helps providers protect credentials, reduce unnecessary standing access and manage both human and non-human identities at scale.

For MSPs, reducing identity security debt goes beyond cleaning up what clients did in the past. It’s about establishing stronger access practices that prevent old patterns from repeating and keep new decisions from adding to the burden. 

Because identity security debt doesn’t disappear with time; it compounds.
