Every extra platform adds credentials, delegated roles, secrets, and logging obligations. That expands the number of places where privilege can persist unnoticed and makes access reviews less reliable. Rationalising tools is therefore an identity-control decision as much as a cost decision.
Why This Matters for Security Teams
Tool sprawl does not just create operational clutter. It multiplies the number of identities, tokens, delegated permissions, and audit trails that must be governed, which makes privilege creep harder to detect and revoke. For MSPs, that is especially dangerous because one platform can become the implicit trust bridge into many client environments. The result is a wider blast radius and weaker confidence in access reviews.
NHIMG research shows that only 5.7% of organisations have full visibility into their service accounts, and 97% of NHIs carry excessive privileges, which explains why identity drift persists even when teams believe controls are in place. That aligns with the broader governance emphasis in the NIST Cybersecurity Framework 2.0, where asset and access oversight are foundational rather than optional.
In practice, many security teams encounter over-permissioned tool access only after a customer audit, a lateral movement event, or an emergency offboarding request has already exposed the gap.
How It Works in Practice
As MSP environments add RMM platforms, ticketing systems, backup tools, SIEM integrations, automation scripts, and client-specific admin consoles, each new integration tends to bring its own service account, API key, certificate, or delegated role. The identity problem is not simply how many tools exist, but how many persistent trust paths they create. Current guidance suggests treating every tool as an identity-bearing workload, not just a software license.
That means building controls around lifecycle, scope, and verification. Start by inventorying non-human identities across all platforms, then map which client systems each identity can reach. Where possible, replace long-lived credentials with short-lived tokens, constrain permissions to the minimum task scope, and revoke access automatically when a job or contract ends. NHIMG’s Ultimate Guide to NHIs highlights how often secrets remain exposed outside secure storage, which is why credential location matters as much as credential strength.
- Use one owner for each tool identity, with explicit business and technical accountability.
- Separate client-bound access so a compromise in one tenant cannot silently extend to others.
- Review delegated roles, OAuth grants, and automation tokens on a fixed cadence, not only during incidents.
- Prefer just-in-time elevation and time-bound secrets over standing administrative access.
For implementation patterns, compare the identity and visibility issues in the Top 10 NHI Issues with the access review expectations in NIST Cybersecurity Framework 2.0; the practical gap is usually not policy intent, but untracked exceptions spread across tools and tenants. These controls tend to break down when MSPs rely on shared admin consoles with inherited permissions because attribution and revocation become ambiguous across customers.
Common Variations and Edge Cases
Tighter identity control often increases operational overhead, requiring MSPs to balance faster service delivery against stronger segregation, review, and revocation discipline. That tradeoff is real, especially in smaller providers where the same engineers support multiple clients and tool owners are not cleanly separated.
Best practice is evolving for environments with heavy automation, because some tools cannot yet support fine-grained, short-lived authorisation without breaking workflows. In those cases, organisations may need compensating controls such as stricter vaulting, enhanced logging, approval gates for elevated actions, and more frequent access recertification. There is no universal standard for this yet, but guidance consistently favors reducing standing privilege wherever the platform allows it.
Edge cases include vendor-managed integrations, emergency break-glass accounts, and inherited access through shared reseller portals. Those scenarios should be treated as exceptions with explicit expiry dates and review triggers, not as normal operating access. NHIMG’s breach research in the 52 NHI Breaches Analysis shows how quickly weak identity controls become incident paths when credentials or delegated permissions are left in place after the original use case has changed.
