Emeka E.

Fractional CISO and Microsoft security architect. I help organizations secure identity, devices, and data in Microsoft 365, then use AI agents and automation to keep that security running without adding headcount. Over the past 13+ years I’ve worked inside the environments I now secure: endpoint engineering, identity, Windows at enterprise scale, and security leadership. On Upwork that’s 9,000+ hours, $400K+ earned, Top Rated Plus, and 100% Job Success, for clients in healthcare, insurance, financial services, energy, and manufacturing. WHAT I DO 1. Security Leadership (vCISO / Fractional CISO) • Security strategy, roadmaps, and board-ready reporting • Risk assessments, policies, and audit and compliance readiness • AI governance: safe, policy-backed adoption of Copilot and other AI tools • Vendor and third-party risk reviews 2. AI Agents and Security Automation • AI-assisted SecOps: automated triage, alert enrichment, and investigation summaries • Monitoring pipelines on Microsoft Sentinel and OpenClaw that catch privileged role changes, sign-in anomalies, MFA failures, and persistence activity, then open tickets automatically • Custom agents and workflows that replace repetitive IT and security tasks (onboarding, access reviews, compliance evidence, reporting) • PowerShell, Microsoft Graph, and Logic Apps automation 3. Modern Microsoft Architecture • Entra ID: Conditional Access, MFA, PIM, RBAC, identity governance, FIDO2 and passwordless • Intune and Autopilot: zero-touch provisioning, compliance, app deployment, Windows, macOS, iOS, and Android • SCCM to Intune and on-prem AD to Entra migrations • Microsoft Defender: endpoint protection, ASR rules, security baselines • Purview: DLP, sensitivity labels, retention, and information protection • Jamf and Apple MDM, Group Policy, Windows Server, MDT HOW I WORK • Assess first: a clear picture of where you stand before anything changes • Build in phases with pilots, so nothing breaks in production • Automate what repeats, so the controls stay in place after I hand off • Document everything: runbooks and handoff sessions your team can actually use WHY CLIENTS HIRE ME I’m not a strategist who has never touched a tenant, and I’m not an engineer who can’t talk to leadership. I do both. I can sit with your executives on risk, then go build the Conditional Access policies, the Intune baselines, and the automation behind them. If you need someone to own your security program, modernize your Microsoft environment, or bring AI into your operations safely, send me a message. I’m happy to start with a short call to map out what you need.
