Strategic security leadership without the full-time overhead. Roadmaps, governance, and executive-ready narratives tied to your mission.

  • Security strategy & IT modernization roadmaps
  • Board & executive briefings
  • Policy alignment with NIST, CIS, ISO

Assessments & Architecture

Deep-dive assessments of critical systems, legacy stacks, and cloud environments with prioritized, realistic remediation plans.

  • NIST CSF maturity assessments

  • Zero Trust & segmentation strategies

Compliance & Resilience

Design controls that survive real audits and real incidents—PCI, CJIS, HIPAA, and state/federal guidance.

  • PCI & CJIS-aligned control mapping
  • Incident response & DR/BC playbooks
  • Tabletop exercises & readiness drills

Structured by Design

Grounded in NIST CSF & RMF

Every engagement is anchored in battle-tested frameworks. No checkbox theater— just clear alignment between controls, risk, and mission outcomes.

NIST Cybersecurity Framework

Five core functions, mapped to your reality.

CSF-1

Identify

Asset, data, and business context to focus effort where it matters.

CSF-2

Protect

Controls, hardening, and training to reduce the likelihood of impact.

CSF-3

Detect

Logging, monitoring, and analytics tuned to your threat landscape.

CSF-4

Respond

Clear playbooks and roles to act fast when an incident hits.

CSF-5

Recover

Resilient backups, DR, and lessons learned baked into the cycle.

NIST Risk Management Framework

Full lifecycle governance for systems that cannot fail quietly.

  1. Prepare — Define context, stakeholders, and risk appetite.
  2. Categorize — Classify systems by impact and mission criticality.
  3. Select — Choose controls that make sense, not just noise.
  4. Implement — Build repeatable patterns with automation in mind.
  5. Assess — Validate controls with evidence, not wishful thinking.
  6. Authorize — Empower leadership with clear risk decisions.
  7. Monitor — Continuously adapt as threats and systems evolve.
