The Business Case for Killing Active Directory

Most organizations think keeping Active Directory around is the cheaper, safer option. It's actually the more expensive one — they're paying for two identity systems at once, and only using one of them. 💸 In this episode, Ernie and Josée make the financial and risk case for retiring on-prem Active Directory. We unpack the "stranded capital" problem: organizations already licensed for Entra ID P1 or P2 are paying for conditional access, risk-based identity protection, and Privileged Identity Management, while simultaneously pouring money into patching, backups, and disaster recovery for dozens or hundreds of branch domain controllers that block those very features from working. 🔒 We look at why the risk case is just as stark — over 78% of ransomware intrusions involve a breached domain controller, with a median time-to-compromise of 3.4 hours, because Active Directory replicates malicious changes exactly as faithfully as it replicates legitimate ones. ⚠️ Then we walk through the actual playbook: the six-rule cloud-first policy that stops new AD dependencies from being created, and the three-phase attrition model that lets the existing environment migrate itself using business clocks you're already funding, rather than a disruptive, unbudgeted rip-and-replace. 📋 You'll leave knowing exactly how to build the financial case for retiring Active Directory, using real ransomware and outage figures a CFO or cyber insurance underwriter will actually respond to. 📊 If you're the one building the business case for this migration, this episode is not optional. ✅ Connect with Ernie Prescott on LinkedIn at linkedin.com/in/ernieprescott
