Client Success Story
Building a CMMC Program from Near-Zero for a Defense and Aerospace R&D Manufacturer
A small R&D manufacturer doing mission-critical defense and space work had the contracts but no documented security program and a non-compliant cloud. InterSec sequenced a from-scratch CMMC Level 2 build against a firm November 2026 deadline.
The Challenge
A hard November 2026 deadline sat in the company's existing and pipeline contracts, and this was a build from near-zero. Documented policies did not exist, network diagrams were incomplete, asset inventories were inaccurate, and several challenges interlocked at once.
The Approach
InterSec's approach was deliberately practical, meeting the company where it was rather than where a textbook assumed it should be. Four concurrent workstreams ran through recurring biweekly meetings and a shared evidence repository.
The Solution in Practice
A shared SharePoint environment became the central evidence repository, with a GRC platform loaded for live SPRS scoring and templates for the fifty-plus required artifacts. Baseline work rebuilt the fundamentals: inventories, network diagrams, data-flow maps, a defined CUI boundary, and an Active Directory cleanup. The GCC workstream handled tenant setup with a government-cloud partner and a subdomain strategy that kept familiar identities while enforcing CUI segregation, and technical remediation covered encryption, least-privilege access, audit logging, and vulnerability scanning.
An existing ISO 9001 documentation culture gave the from-scratch CMMC build a real head start, so the job became mapping and aligning rather than building from zero.
Results & Impact
As of April 2026, with the deadline seven months out, the program has moved from nonexistent to structured and progressing.
Key Takeaways
Working With InterSec
A near-zero start and a hard deadline is a hard combination, but a manageable one.
A sequenced program makes it work. InterSec prepares defense and aerospace contractors for CMMC assessment and builds the evidence trail that holds up. Let's map your path.
