Manufacturing IT lives in two worlds: the office network that runs ERP, email, and accounting; and the shop-floor OT network that runs CNC controllers, PLCs, scanners, and instruments that cannot afford downtime, updates on their own schedule, or exposure to the wider internet.
Our manufacturing practice covers Fullerton, Anaheim, Torrance, and the El Segundo aerospace corridor. Whether you're a family-owned Fullerton machine shop or a Tier 2 aerospace supplier chasing your first DoD contract, we design environments that keep the line running and stand up to the compliance frameworks your customers demand.
CMMC 2.0 is real and dated
DoD contract awards from 2026 forward require CMMC. Getting from where most shops are today to Level 2 assessed is a 90–180-day project, and it starts with a real gap analysis — not a checkbox spreadsheet.
Flat networks between office and shop
Most shop networks we inherit have accounting workstations on the same broadcast domain as PLCs. One phishing click and the ransomware reaches the CNCs. We segment, always.
ERP that can't go down
Fishbowl, Sage 100, Global Shop, ECI M1, Epicor, JobBOSS — when it's down, orders don't ship. We monitor the SQL back end, the ERP services, and the integrations, not just the ping.
Compliance
Compliance frameworks we deliver against
Manufacturers face a stack of overlapping requirements. We map controls once to a unified baseline, then generate the evidence each framework wants.
CMMC 2.0 (Level 1 & Level 2)
SSP and POA&M documentation, technical controls implementation, and pre-assessment readiness for C3PAO engagement.
NIST SP 800-171 Rev. 2 & Rev. 3
All 110 requirements addressed, tracked, and evidenced. SPRS score improved and maintained.
ITAR
US-person access enforcement, encrypted export-controlled data storage, and physical access controls.
ISO 27001 / IEC 62443
For manufacturers whose customers require ISO or industrial cybersecurity certifications.

Real-world outcome
Case in point: an El Segundo aerospace subcontractor
A 45-employee aerospace machining supplier needed to bid on a DoD contract that required CMMC Level 2 within six months. Their existing IT was a flat network, no MFA, and backups that had never been restored. In 120 days we segmented the network, deployed conditional-access MFA, rebuilt the endpoint image, produced a compliant System Security Plan, and closed 108 of 110 NIST 800-171 controls (the last two required customer-side coordination). Their C3PAO assessment passed on the first attempt, and the contract was awarded three weeks later.
They took us from 'nowhere near ready' to certified in four months. We won the contract.

FAQ
Manufacturing & Defense Suppliers IT — questions we get
How long does CMMC Level 2 readiness typically take?
For a mid-sized manufacturer with a mixed environment, 90 to 180 days from gap analysis to assessment-ready. Simpler office-only environments trend to the low end; complex OT environments to the high end.
Do you handle the C3PAO assessment coordination?
Yes — we act as your IT liaison during assessment, provide evidence packages ahead of time, and remediate any conditional findings between assessment stages.
Can you keep our CNC and shop-floor equipment secure without breaking anything?
Yes. Our OT approach is 'segment first, monitor second, patch carefully.' We don't push updates to production controllers without vendor sign-off. Isolation limits the blast radius when something goes wrong upstream.
Do you support both cloud and on-prem ERP?
Yes. Fishbowl, Sage 100, Global Shop, ECI M1, and Epicor run just fine on properly configured Windows Server. We also migrate to hosted or SaaS when the business case supports it.
How do you protect CAD files and IP?
Endpoint DLP, data classification, application allowlisting, and segmented storage for engineering data. Access is logged and reviewed quarterly.
Can you help with ITAR US-person access controls?
Yes. Identity-based access enforcement, encrypted storage for export-controlled data, physical access controls, and documented policies. We've supported ITAR-aware environments in South Bay and Orange County.
