Active Directory Security Assessment: Real Cost, Real Deliverables, and the Findings That Actually Matter in 2026
A CTO at a 640-employee logistics company forwarded a cyber insurance renewal questionnaire with a fresh annex titled Identity Infrastructure Posture asking for the most recent independent AD assessment, the Critical and High findings count with remediation status, and an attestation letter. Three quotes ranged from USD 4,800 to USD 38,500 for the same thing. We scoped a 12-business-day assessment at USD 11,800 fixed price against one forest, two domains, 7 DCs, 1,840 user accounts. The findings register shipped 31 items ranked Critical to Informational. The BloodHound attack-path graph showed 14 owned paths to Domain Admin. A 4-hour Tier 0 isolation change window closed 11 of the 14 paths on Day 1. The renewal closed at flat premium on Day 19. From 41 AD assessments over 24 months on forests from 180 to 14,000 users, the 10-domain checklist that produces a defensible report. Four pillars (Privileged Access, Authentication Protocols, Object ACLs, Hardening and Logging). The four privileged-access findings that close most real AD compromises (Tier 0 hygiene, Domain Admin sprawl, gMSA migration, built-in Administrator). Auth findings (Kerberoasting in 38 of 41 forests, unconstrained delegation in 19, NTLM relay in 26) with prevalence and exploit-time data. Open-source tooling (PingCastle, BloodHound CE, PurpleKnight) covering 70 percent of paid auditor scope and what each misses. What a real deliverable contains. Three honest pricing tiers (Single-Forest USD 6.5K-11.5K, Multi-Domain USD 12K-18K, Enterprise USD 22K-38K). A 60-day remediation plan. Four delivery models (fixed-fee external, hybrid, quarterly retainer, accelerated pre-deal). Six FAQ entries.
