TL;DR: Mergers and acquisitions compress two security cultures into one access model, and StrongDM’s checklist shows why standing privilege, orphaned service accounts, weak monitoring, and slow lifecycle cleanup become immediate breach and compliance risks during integration. Secure access integration now depends on governance speed, not just tooling depth.
Editorial analysis by NHI Mgmt Group, based on content published by StrongDM: “Merger and Acquisition PAM Checklist: 7-Day Playbook for CISOs”.
Key questions
Q: What breaks when privileged access is not continuously governed?
A: When privileged access is not continuously governed, standing privilege persists, dormant accounts remain usable, and the attack surface expands across human and machine identities.
Q: Why do mergers and acquisitions increase privileged access risk so quickly?
A: M&A combines different identity models, different infrastructures, and different levels of PAM maturity under a single operating timeline.
Q: How do security teams know whether M&A access integration is actually working?
A: Look for evidence that privileged access is being issued on demand, expired automatically, and logged at the session level.
Practitioner guidance
- Inventory inherited privileged accounts Map every admin, DBA, cloud, and service account in the acquired environment before granting any broader access.
- Replace standing privilege with JIT access Use time-bound elevation for engineers and operators who need access during integration, and deny persistent privileges by default.
- Tie PAM to identity lifecycle workflows Connect joiner, mover, and leaver changes to privileged access revocation so acquired staff, contractors, and service identities lose access when ownership changes.
Bottom line: M&A exposes hidden privilege because two access models are merged before ownership, monitoring, and revocation have been reconciled.

M&A exposes a privileged access governance debt, not just a tooling gap. The moment two organisations combine, the buyer inherits access it did not design, approve, or fully understand. Standing privilege, dormant admin accounts, and orphaned service accounts become governance debt that must be paid down before the merged estate is defensible. The practitioner takeaway is to treat the first week after close as an access reconciliation period, not a normal onboarding cycle.
A few things that frame the scale:
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: Should organisations prioritise PAM redesign before or after acquisition close?
A: Before and immediately after, because inherited privilege becomes harder to unwind once business operations depend on it. A post-close delay gives dormant accounts, orphaned service identities, and bad trust relationships time to harden into normal access patterns. The safest sequence is to stabilise privileged access first, then expand integration.
