Federal Cybersecurity Founder-Led Delivery

Compliance Built on Execution, Not Theory

Aegidis helps defense contractors handle NIST 800-171, CMMC, and Zero Trust work from a founder who has personally run these transitions — on classified government networks and inside a Fortune 500 carrier. The same principles apply whether the problem is a compliance gap on a network or an authentication gap on a steel asset. Both come down to the same question: how do you prove what happened, and make that proof stick?

Who is delivering this Justin Brown, Founder. Three years supporting Army defensive cyber operations at RCERT-South / CTNOSC (Fort Huachuca, 2011–2014) — SCIF-based work on NIPR, SIPR, and coalition networks under a previously held TS/SCI clearance, including a full Juniper NetScreen to Palo Alto NGFW migration on SIPR. Followed by a decade inside a Fortune 500 insurance carrier's security organization, now Manager of Cloud Security Engineering — principal architect on the carrier's Zscaler ZIA and ZPA Zero Trust transition, primary driver of its Zero Trust Maturity Model program against CISA ZTMM and NIST SP 800-207, and inventor of a patent-pending hardware-rooted asset identity platform (USPTO #63/940,006).

Six named offerings

NIST 800-171 Assessments

Control-by-control gap review focused on evidence and remediation order.

  • Map current controls to 800-171 requirements.
  • Identify high-risk evidence gaps first.
  • Deliver a practical remediation sequence.

CMMC Readiness Support

Pre-assessment readiness support before external pressure arrives.

  • Define boundary and inherited controls.
  • Clarify provider vs. internal responsibilities.
  • Build an assessment-ready evidence package.

Zero Trust Architecture Design

Zero Trust architecture support grounded in real enterprise transitions.

  • Prioritize identity, device, and access controls.
  • Plan migration off legacy VPN/perimeter patterns.
  • Align controls to operations and staffing reality.

Zero Trust Maturity Assessment

Maturity evaluation against CISA ZTMM and NIST SP 800-207.

  • Score current maturity by pillar.
  • Test claimed capabilities against evidence.
  • Produce a phased improvement roadmap.

Third-Party Risk & Shared Responsibility

Shared-responsibility analysis for MSP and cloud-heavy environments.

  • Separate provider obligations from yours.
  • Surface contract and control boundary gaps.
  • Document accountable owners per requirement.

Engineering-Aware Security

Security guidance written for real engineering constraints.

  • Account for change windows and uptime limits.
  • Design around OT/legacy operational constraints.
  • Focus on controls teams can actually run.
Buyer Fit
Where this is strongest
  • Defense contractors preparing for NIST 800-171 or CMMC assessment pressure.
  • Suppliers handling engineering data, technical drawings, or CUI-adjacent workflows where policy must align with manufacturing and operational reality.
  • Organizations whose Zero Trust claims need to survive an external maturity evaluation against CISA ZTMM or NIST SP 800-207.
  • Programs where cyber decisions must align with how equipment, factories, or operational technology systems actually run.
  • Buyers who need direct technical access rather than policy-only consulting from a junior delivery layer.
Delivery Model
Clear next step

Assessment First

Start with a scoped gap review to determine whether the right next move is remediation planning, architecture support, or a maturity assessment against a specific framework. Scoping is a real conversation, not a form.

Prioritized Remediation

Turn findings into a practical sequence tied to staffing, budget, and operational constraints — rather than a compliance shopping list disconnected from how the organization actually functions.

Direct Leadership Access

Work directly with founder-led technical leadership for scoping, tradeoffs, and decision support through delivery. The person who assessed is the person who remediates.

Good fit: defense contractors who want compliance work done by someone who has run a SIPR firewall migration, managed security policy across a hybrid MSP boundary, replaced a perimeter with Zscaler at Fortune 500 scale, and driven a Zero Trust Maturity program against CISA and NIST frameworks. If the work requires someone who has actually done it, that's where this fits.
