MNPI compliance and PBAC: what IAM teams need to change

TL;DR: Material nonpublic information controls fail when access is broad, context is ignored, and audit trails are thin, according to PlainID’s analysis of PBAC for sensitive data compliance. Static permissions do not match how legal, finance, expert-network, and AI-assisted workflows actually reach MNPI, so governance must move to contextual authorisation.

NHIMG editorial — based on content published by PlainID: Data Compliance and MNPI, focused on protecting sensitive information with PBAC

By the numbers:

• Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.
• 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface.
• 79% of organisations have experienced secrets leaks, with 77% of these incidents resulting in tangible damage.

Questions worth separating out

Q: How should security teams control access to MNPI without slowing business workflows?

A: Use policy-based access control to evaluate role, device trust, location, time, and data sensitivity at request time.

Q: Why do static permissions create risk for MNPI governance?

A: Static permissions become risky because they ignore changing context.

Q: What do organisations get wrong about separation of duties for sensitive data?

A: They often treat separation of duties as a paperwork control instead of an operational one.

Practitioner guidance

• Segment MNPI into explicit policy classes Define MNPI as a first-class access category in your policy model, then map legal, finance, executive, and external collaborator workflows to separate rules with distinct approval and exposure conditions.
• Tie access decisions to device and location signals Block or step up access when unmanaged devices, remote logins, or unusual geographies intersect with sensitive data requests, especially during blackout periods and deal-sensitive windows.
• Enforce separation of duties in sensitive workflows Prevent the same person or team from both approving and acting on the same MNPI-related process, and log any exception as a reviewable policy event.
