The Era of "Governance Cosplay" is over. I am a Value Architect and Trust Agent on a mission to move GRC beyond the performance of "checking boxes." In a world of increasing systemic complexity, I transform governance from a static reporting function into a dynamic discipline: Engineering a Hardened Core. As the Founder & Managing Principal of Cyberspace Consulting, I help founders and leadership teams navigate the digital cosmos with confidence. Rather than focusing on surface-level compliance, we build the architecture required to launch into new frontiers. We replace fragmented programs with the Cyberspace Core Framework – a high-integrity methodology that minimizes overhead, maximizes ROI, and enables you to land, expand, and retain customers. I am an independent, US-based cybersecurity governance, risk, and compliance principal with deep technical expertise in cloud infrastructure and enterprise security frameworks. Having executed 300+ successful GRC engagements, audits, and enterprise implementations, I bridge the gap between executive leadership and technical engineering teams. I hold 13 global industry credentials across strategic security, audit/assurance, privacy, and emerging tech. When you hire my firm, you get my full, tenured dedication – no junior navigators, no outsourcing, and zero bureaucratic drag. I build compliance programs that integrate directly into your day-to-day operations and SDLC, enabling you to land, expand, and retain enterprise customers. My Approach: The Cyberspace Core Covenant Our mission: secure and optimize your Cyberspace – one person, process, and technology at a time. We operate under a strict code: ✦ Mission Success: Your mission is our mandate. I provide direct, high-level leadership. ✦ Galactic Excellence: We never settle for the baseline; we elevate your security posture beyond the horizon. ✦ Long-term Partners: We integrate into your crew, aligning our trajectory with your sustained growth. ✦ Zero Outsourcing: No junior navigators; you get my full, tenured dedication. EXPERTISE & CORE SERVICES: ✦ Strategy & Fractional vCISO Leadership Board-level reporting & maturity roadmaps Third-party risk management & sales enablement Business Continuity, Disaster Recovery, and Incident Response architecture Security program assessment, policy engineering, and risk management ✦ Audit Readiness & Full-Lifecycle Framework Management SOC 2 (Type I / Type II) & SOC 1 / SOC 3 ISO 27001 / ISO 27701 / ISO 42001 (AI Governance) HIPAA / HITECH Security Risk Analysis & Readiness NIST CSF, 800-171, GDPR, CCPA, PCI DSS, SOX 404 ITGCs ✦ Technical Control Engineering & Cloud Security AWS-native security architecture, cloud governance, and IAM Technical remediation, gap assessments, and continuous monitoring Translating complex regulatory requirements into scalable code and infrastructure specifications Protecting engineering velocity – securing systems without slowing product deployments ✦ Specialized Infrastructure & Email Security Advanced DNS, SPF, DKIM, and DMARC compliance and domain protection Email deliverability and security optimization (M365, Google Workspace, AWS Route53, Cloudflare) The Foundation This isn't theory; it is battle-tested operational reality backed by 13 global credentials across four domains: ✦ Strategic Security & Governance: CISSP, CISM, CRISC ✦ Audit & Assurance: CISA, CIA, ISO 27001 / 27701 / 20000 Lead Auditor ✦ Privacy & Data Protection: CIPM, CDPSE, CIPP/US ✦ AI & Emerging Tech: ISO 42001 Lead Auditor, CCSK Let’s Build My career has been defined by three distinct strategic chapters. The first was built as an external auditor and trusted advisor, driving high-impact compliance; the second, as a GRC leader maturing risk postures within global organizations; and the third, as a Founder dedicated to architecting frameworks that actually persist. I am building for velocity and engineering for readiness. If you are a leader hitting "compliance drag" that prevents growth, let’s talk. This mission – bringing my experience from both sides of the table to secure your cyberspace and harden the core – is the foundation of everything I do at Cyberspace Consulting. Are you ready for launch? 🚀 Chart your course here: cyberspacecore(dot)com ✦ Security Program takes Flight. Secure your cyberspace. Harden the core.

What I do ・Global SD-WAN/SASE design, rollout, and path-quality/failover tuning ・Internet security & endpoint stacks (ZIA/ZPA/ZDX, GlobalProtect, CrowdStrike, Proofpoint) ・Enterprise LAN/WAN/wireless architecture and troubleshooting ・GenAI/Agent AI PoC → production, with measurable business impact Keywords: SD-WAN, SASE, Zero Trust, ZIA/ZPA/ZDX, GlobalProtect, IPsec, BGP/OSPF, IP/MPLS, Segment Routing, Python, Azure OpenAI, RAG

Hey, I’m James. I’ve been a self‑employed business network and server admin for 25+ years, building and supporting critical infrastructure for SMBs and enterprises across the country. I work daily with Linux and Windows environments, VMware and Proxmox clusters, and complex networks that simply cannot go down. Many of my core clients have trusted me with their systems for over 20 years, because I focus on rock‑solid uptime, clear communication, and long‑term relationships—not quick fixes. I specialize in infrastructure that has to “just work”: virtualization, storage, networking, security, and web hosting. Recent work includes fully automated multi‑node VMware + vSAN builds using IPMI, PowerShell, and Python; high‑availability WordPress platforms with 50,000+ active members and 99.999% uptime; and deep network redesigns with Unifi, VLAN cleanup, and clear documentation your internal IT team can actually use. At the enterprise level, I’ve redesigned infrastructure for a 6‑billion‑dollar publicly traded company, implementing redundant firewalls, VMware hosts, dual fiber to AWS with VPN failover, and power redundancy—while reducing monthly management costs by over 25,000 and consolidating 20+ servers to 8. I’ve also delivered CMMC v2 cybersecurity implementations for government contractors, combining policy, technical controls, and staff training into a practical, auditable program. ​ If you’re looking for top‑tier help (not the cheapest bid) with cloud infrastructure, virtualization (VMware/Proxmox), network security, database and web hosting, or compliance‑driven environments, let’s talk. Send a brief overview of your current setup, pain points, and goals, and I’ll come back with a clear, no‑nonsense plan to stabilize, simplify, and scale your infrastructure. When you hire me, here’s what you can expect: 1. Click the “Invite” button to share your job and a brief overview of your environment. 2. Once we’re matched on Upwork, we’ll jump on a call (Zoom or phone) to walk through your current setup and objectives. 3. I’ll ask targeted questions to clarify requirements, risks, and success criteria so we’re aligned on exactly what “done” looks like. 4. I’ll send you a high‑level written plan outlining the approach, milestones, and estimated hours or budget. 5. When we agree on the plan and timeline, I’ll execute, keep you updated as we go, and document everything so your team isn’t left in the dark. If this sounds like the level of help you’re looking for, click “Invite” and let’s get your infrastructure stable, secure, and easy to manage.
