Security design.
Practical proof.
I bring enterprise security experience to practical control design. I led SOC 2 audit readiness for IBM Cloud teams and coordinated HSM vulnerability remediation in financial services. Exposure Control shows how I translate that experience into an AI-assisted, synthetic security platform.

Review scope
AI assistant permissions & boundary review.
I review what an assistant can access, what it can do, and where human approval is required.
I agree on scope, deliverables, systems, access, safe tests, and exclusions with you before testing.
Keep credentials and sensitive data out.
Review approved access and permission boundaries
Test only the agreed actions and systems
Document tested actions, observed results, and recommended fixes
Hand off findings and next steps; negotiate a retest if needed

How I work.
I review finding evidence and business context, agree on remediation owners and next steps, and check whether the closure criteria were met.
Connect findings to assets and owners
Check evidence before escalation
Prioritize by exploitability and business impact
Agree on owners, deadlines, and closure checks
Direct answers
How prioritization and closure work.
What is cyber exposure architecture?
In this portfolio, cyber exposure architecture connects vulnerability findings to affected assets, business importance, controls, and remediation owners. Exposure Control demonstrates these links with fictional data.
How do organizations prioritize vulnerabilities by business risk?
Consider exploitability, whether the asset can be reached, its business importance, data sensitivity, and existing controls. Assign an owner and use those factors to decide which findings need attention first.
How does exposure control connect engineering, architecture, and executives?
The synthetic Exposure Control project shows finding priorities, affected applications, remediation owners, and closure checks. Engineers and leaders can inspect the same records when deciding what to fix and what remains open.
What does evidence-gated closure mean?
Closure requires validation data confirming that the finding was resolved or meets an approved control criterion. Without that evidence, the finding stays open or returns to remediation.
