🔐 Your enterprise deal is stalling — because security is unresolved.
A customer asks for a SOC 2 report. An ISO 27001 certificate. A completed security questionnaire. Your team doesn't have the answers, and the deal slows down.
I step in as your fractional vCISO and fix that, fast.
With 10+ years building and running security programs — and a technical foundation in infrastructure, endpoint, identity, and network security — I've helped SaaS, healthcare, fintech, and managed services companies go from zero compliance posture to full audit readiness.
🎯 What I deliver:
• 📋 Compliance programs — SOC 2 (Type 1 & 2), ISO 27001:2022, ISO 42001 (AI Governance), ISO 27701 (Privacy), ISO 22301 (BCM), HIPAA, PCI DSS, GDPR, FedRAMP, CIS Controls — gap assessments, implementation, evidence collection, and audit preparation from start to finish
• 🛡️ Fractional vCISO — security program design, policy & procedure library, risk register, vendor risk management, board-level reporting, AI/SaaS third-party risk, and supply chain risk
• 🔑 Identity & Access Management — Microsoft Entra ID, Conditional Access, Privileged Access Management, MFA deployment, JML processes, and password manager deployment (Keeper, 1Password, Bitwarden, ITGlue)
• 💻 Endpoint & device management — Microsoft Intune (end-to-end), IBM MaaS360, Cisco Meraki MDM, system hardening, BitLocker, Windows hardening, Microsoft 365 Business Premium configuration
• 🛰️ Security operations — SIEM deployment & tuning (Splunk, QRadar, Microsoft Sentinel, Wazuh, Elastic/ELK), MDR (BlackPoint, Huntress, Sentinel Suite, TrendMicro), DFIR, vulnerability management, threat intelligence
• ⚙️ Compliance automation — Vanta, Drata, Secureframe, GRC engineering
• ☁️ Cloud security — AWS, Azure, GCP
• 📐 Framework alignment — NIST CSF 2.0, NIST SP 800-53, ISO 27005/31000, COBIT, CIS Controls
🔧 Why my compliance work is different:
Most compliance consultants work from a checklist. I've actually built what I audit — I've deployed MDM solutions, run enterprise vulnerability management programs, managed SAST and application security pipelines, operated MDR platforms, and hardened endpoints and infrastructure across managed services client bases. That technical depth means the controls I design actually work in the real world, not just on paper. When your auditor asks hard questions, I already know the answers.
📌 My track record includes:
• ✔ Built and operated end-to-end ISMS as fractional vCISO — from policy library to enterprise risk register
• ✔ Leading ISO 27001 ISMS lifecycle, ISO 27005 risk assessments, and ISO 27701 (PIMS) implementation at enterprise level
• ✔ Deployed and managed MDM solutions (Intune, MaaS360, Meraki) and EDR/MDR platforms across MSP client bases
• ✔ Designed and executed enterprise-wide vulnerability management programs, AppSec pipelines (SAST), and security awareness programs
• ✔ Led AI/SaaS third-party risk assessments and board-level security reporting
🔄 How I engage:
Scoping call → gap assessment → prioritized roadmap → implementation → audit support. Open to short engagements (policy review, gap assessment, security posture assessment, endpoint hardening) or long-term fractional vCISO retainers.
📩 Message me with your target framework, environment, or challenge — I'll send back a clear path forward within 24 hours.
