Control the Flow of CUI. Protect the Outcome.

Perezdiaz, LLC is a veteran-owned and operated firm helping Defense Industrial Base organizations meet mandatory cybersecurity requirements with clarity, accountability, and confidence.

The firm supports organizations operating under the Cybersecurity Maturity Model Certification (CMMC) framework and related Department of Defense requirements. Perezdiaz, LLC is registered in the System for Award Management (SAM) and maintains active entity identifiers, including CAGE registration.

With more than 20 years of experience supporting, assessing, and protecting aerospace and defense programs, Perezdiaz, LLC brings assessment-grade realism to cybersecurity and compliance efforts where failure carries real operational and contractual consequences.

Perezdiaz, LLC was founded on a simple belief:

Controlled Unclassified Information matters because missions, people, and outcomes depend on it.

Too many organizations are forced into compliance conversations centered on tools, checklists, and point-in-time assessments. That approach ignores how defense and federal contractors actually operate, and how CUI is created, shared, and used every day to design, build, and deliver capability to the U.S. Government.

Effective compliance must reflect operational reality, not just written intent.

Before founding Perezdiaz, LLC, the firm’s founder served honorably in the United States Air Force and continued mission-driven work supporting the U.S. Federal Government in operational and national security environments. His career includes:

• Direct support to the National Military Command Center (NMCC) under the Defense Information Systems Agency
   
• Federal civilian service as a GS-2210 IT Specialist supporting joint operations and intelligence missions
   
• Independent contractor support to organizations including the Army Logistics Innovation Agency, the Office of the Secretary of Defense, and the Department of State
   

These roles shaped a practical understanding of how sensitive information must be protected when decisions carry real-world consequences.

The founder later served as IT Risk and Compliance Leader for a Fortune 500 prime contractor operating across specialty materials, life sciences, research and development, and advanced manufacturing.

In that role, he led NIST SP 800-171 implementation and a successful DIBCAC High Assessment, aligning cybersecurity practices with DFARS 252.204-7012 while balancing operational, contractual, and business realities.

That experience exposed a persistent gap between how compliance is often described and how it must function inside complex organizations.

As a consultant, the founder has built and scaled multiple Registered Provider Organization (RPO) practices, growing programs from fewer than five clients to double digits in under a year.

His work includes:

• Leading organizations through successful CMMC Level 2 assessments
   
• Preparing prime contractors and subcontractors for DIBCAC High assessments
   
• Supporting organizations planning for CMMC Level 3 readiness
   
• Helping leadership teams distinguish what is defensible, what is risky, and what cannot be deferred
   

His thought leadership has been recognized nationally through speaking engagements at CMMC Day, CEIC East, CEIC West, CS5 East, CS2 Boston, and other key industry forums.

Perezdiaz, LLC is not built to sell remediation, tools, or generic consulting packages.

The firm provides independent, risk-based assurance focused on:

• CUI programs designed with clear accountability
   
• Assessment-grade readiness and independent validation
   
• Evidence quality, traceability, and governance discipline
   
• Preparation for formal assessments, not just internal reviews
   

The objective is simple:

When an assessment begins, leadership should already know the outcome.

Working with Perezdiaz, LLC means your CUI program is treated as an operational system, not a documentation exercise.

In practice, that means:

Clear ownership of CUI and security decisions

Organizations can identify who owns CUI, who authorizes access, who is accountable for controls, and who makes risk decisions, without ambiguity or overlap.

Readiness evaluated the way it will actually be assessed

Program readiness is measured against how formal assessments evaluate implementation and evidence, not against checklists, tool outputs, or optimistic interpretations.

Evidence that tells one consistent story

Policies, procedures, system configurations, and artifacts align and can be traced back to clear implementation statements and governance decisions.

Governance that holds up under pressure

Changes, exceptions, and risk decisions are documented, justified, and defensible when questioned by assessors, prime contractors, or the government.

Leadership confidence before assessment day

Affirming Officials and senior leaders understand what is being asserted, why it is being asserted, and where the program’s true risks and strengths lie.

The founder holds:

• Master of Science in Information Technology
   
• Graduate Certificate in Project Management
   
• Bachelor of Science in Business Administration
   

Professional credentials include:

• Certified Information Systems Auditor (CISA)
   
• Certified in Risk and Information Systems Control (CRISC)
   
• Certificate of Cloud Security Knowledge (CCSK)
   
• Certified CMMC Assessor (CCA), among the first 100 nationwide Lead CCAs
   
• Certified CMMC Professional (CCP)

• Six Sigma Yellow Belt

• ITIL Foundation (IT Service Management)
   

These credentials support the mission. They do not define it.

Perezdiaz, LLC exists to help organizations control the flow of Controlled Unclassified Information, build accountability around its use, and stand behind their compliance posture with confidence when it is subject to formal assessment.

CUI matters because missions, people, and outcomes depend on it. Effective protection requires more than tools, checklists, or point-in-time assessments. It requires programs that reflect how defense and federal contractors actually operate, how information is created and shared, and how risk decisions are made in the real world.

In practice, this mission is carried out by delivering independent, assessment-grade assurance for organizations operating under NIST SP 800-171, DFARS 252.204-7012, and the CMMC framework.

The focus is not certification theater.

The focus is defensible compliance and accountable CUI programs.
